You should noticed that this question is old and the short tags issue was mentioned 16 times, also in the top comment of my question.
I just share my solution, I was also facing the same error and after executing this command of mcrypt my issue solved. I was just missing the libapache2-mod-php7. Henry van Megen Henry van Megen 2, 2 2 gold badges 21 21 silver badges 32 32 bronze badges. Where are these config settings exactly?
For existing hosts, you need to edit apache config in webmin. Eitherway, this is not as secure as fastcgi - virtualmin's default. So the correct approach should be to troubleshoot why fcgi doesn't work, for example it may be caused by file permissions.
If you're using a version of Apache that doesn't have httpd. I know it should sound silly PHP works fine checked using command line. Thanks for the help. Dummy I am xampp but it works fine.

The syntax of JavaScript if-else statement is given below. It is just like else if statement that we have learned in previous page. But it is convenient than if.. The signature of JavaScript switch statement is given below. PHP is a open source, interpreted and object-oriented scripting language i.
It is used to develop web applications an application i. PHP 2 transformed the language into a Server-side embedded scripting language. Added database support, file uploads, variables, arrays, recursive functions, conditionals, iteration, regular expressions, etc.
PHP 4 became an independent component of the web server for added efficiency. The parser was renamed the Zend Engine. Many security feature were added. File: hello. It is available for all operating systems. The program runs as a server providing multi-user access to a number of databases.
They run on both linux and windows servers so your web host most likely supports it. With the advent of PH5, PHP language has evolved to be an object oriented programming language enabling more robust and standards based web applications..
PHP or PHP Hypertext Preprocessor is a server-side scripting language that is used to create dynamic web pages that can interact with databases.
It is a widely-used open source language that is specifically used for web application development and can be embedded within HTML. The distinguishing feature of PHP is that the scripting code is executed on the server, which generates HTML that is sent back to the client. The client receives the result of executing the script without knowing the underlying code. Any website can require a variety of data or information to display and to retrieve them from the database.
This can include display of a simple list to the running of the website based on data stored in the database. The PHP script can also maintain a count of banner views and clicks from the website.
The PHP script can. Defining the command as a variable. The result of the operation will be assigned to the variable 9. The server software is freely distributed, and the open source license means users can edit the underlying code to tweak performance and contribute to the future development of the program — a major source of its beloved status among its proponents.
Support, fixes and development are handled by the loyal user community and coordinated by the Apache Software Foundation. As is expected of a core Microsoft product, it only runs and is bundled on Windows operating systems, but is otherwise free for use. It is a closed software product and supported by solely by Microsoft. Although development is not as open and quick as the open-source user-supported nature of Apache, a behemoth like Microsoft can throw formidable support and development resources at its products, and IIS has fortunately benefitted from this.
As someone with no prior experience in JavaScript whatsoever I believe my time spent in training and discovering new languages was well worth it and contributed to finding an acceptable solution to an important aspect of web design and development. Although I have often stumbled upon these problems at University, they had to be approached differently in a working environment.
Working with web development languages has increased my interest in them, hence prompting me to transfer to the Web Design and Development course at my college.
The purpose is to easily create and manage a new Apache Karaf runtime without installing a complete distribution. A instance is a new instance that you can launch separately from the root one, and deploy applications into. It means that each instance is run on a different JVM. A instance does not contain a full copy of the Apache Karaf distribution, but only a set of the configuration files and data folder which contains all the runtime information, logs and temporary files.
The new instance is a new Karaf instance and is assigned an SSH port number based on an incremental count starting at and a RMI registry port number based on an incremental count starting at The new instance is a fresh Apache Karaf instance. It uses the same default configuration files, as when you install a fresh Karaf distribution. You can enable the verbose mode for the instance:create command using the -v option:. You can manually configure the different ports, the location of the instance, the Apache Karaf features URLs using different options of the instance:create command.
You can have details about these options using the --help option. Instead of creating a fresh instance, you can clone an existing instance using instance:clone. You find a directory with the name of the instance storing the different instance files. You can change the location of the instance using the -l option to the instance:create and instance:clone commands:.
You can change the SSH port number assigned to an instance using the instance:ssh-port-change command:. To list the instances and their current status, you can use the instance:list command:.
You can get directly the status of a given instance using the instance:status command:. You can connect to a running instance directly from the root one using the instance:connect command:.
By default, this command will use the same username used on the root instance, and the password will be prompted. You can use a different username using the -u or --username option. You can also provide the password using the -p or --password option. You can logoff from the instance and return back to the root instance using the logout command or CTRL-D key binding:.
The instance:connect command accepts shell commands as argument. It allows you to directly execute commands or scripts on the instance:. To stop an instance, you can connect to the instance using instance:connect and execute the system:shutdown command. The instance:destroy deletes the instance store the location where the instance files are stored. For instance, to list all the instances, you can use the instance script with the list command:. You can obtain details about commands options and arguments using the --help option.
The Instances attribute is a tabular data attribute providing details about the instances:. If wait is true, this operation is waiting for the instance is in "Started" state. If debug is true, the instance is started in debug mode. If verbose is true, this operation provides details in the log. Apache Karaf is able to manage multiple realms. The login modules define the authentication and authorization for the realm. This login module authenticates the users and returns the users' roles.
This file contains the users and a public key associated to each user. You can manage an existing realm, login module, or create your own realm using the jaas:realm-manage command. If a new realm should be added Apache Karaf provides an easy way to create a new Realm although with limited flexibility compared to other approaches like blueprint or directly via DS. The jaas:realm-add command can be used for that purpose. Note, that it takes at least 2 Parameters name of the realm and class name of the initial Login Module or even more, if the Login Module needs parameters.
To add a new Login Module to an existing realm the jaas:module-add command can be used. It is similar in semantics than the jaas:realm-add command except that it takes no realm name.
Instead, the realm to modify has to be selected via jaas:realm-manage previously. Note that the options for the Login Module are given as a list of parameters which is interpreted as a map in the order "key1 value1 key2 value2". So the command. We can see in this file, that we have one user by default: karaf. The default password is karaf. A group defines a set of roles. By default, the admingroup defines group , admin , manager , and viewer roles.
It means that the karaf user will have the roles defined by the admingroup. To identify the realm and login module that you want to manage, you can use the --index option. The indexes are displayed by the jaas:realm-list command:. Another way is to use the --realm and --module options.
The --realm option expects the realm name, and the --module option expects the login module class name:. When you are in edit mode, you can list the users in the login module using the jaas:user-list :. The jaas:user-add command adds a new user and the password in the currently edited login module:. To "commit" your change here the user addition , you have to execute the jaas:update command:. On the other hand, if you want to rollback the user addition, you can use the jaas:cancel command.
Like for the jaas:user-add command, you have to use the jaas:update to commit your change or jaas:cancel to rollback :. The jaas:group-add command assigns a group and eventually creates the group to a user in the currently edited login module:. The jaas:group-delete command removes a user from a group in the currently edited login module:. The jaas:group-role-add command adds a role in a group in the currently edited login module:. The jaas:group-role-delete command removes a role from a group in the currently edited login module:.
The jaas:update command commits your changes in the login module backend. If the encryption. With encryption enabled, the password are encrypted at the first time a user logs in. The encryption. The default is "basic" which just supports basic digesting of the password, without salting.
This is not secure for production environments. A more secure alternative is "jasypt", which supports digesting with salting. However, the most secure alternative which should be used in production is "spring-security-crypto", which supports modern password digest algorithms such as "argon2" and "bcrypt".
The default is SHA since Karaf 4. When the "spring-security-crypto" encryption. The possible values are hexadecimal or base The default value is hexadecimal. For the SSH layer, Karaf supports the authentication by key, allowing to login without providing the password.
NB: you can provide a passphrase with -N option to ssh-keygen but, in that case, you will need to enter the passphrase to allow the SSH client to use the key. You copy the key from karaf. Here, we define that feature:list and feature:info commands can be executed by users with viewer role, whereas the feature:install and feature:uninstall commands can only be executed by users with admin role. Note that users in the admin group will also have viewer role, so will be able to do everything. Only the users with admin role can execute feature:install , feature:uninstall , feature:start , feature:stop and feature:update commands.
Only the users with admin role can execute jaas:update command. Only the users with admin role can execute kar:install and kar:uninstall commands.
Only the users with admin role can execute shell:edit , shell:exec , shell:new , and shell:java commands. Only the users with admin role can execute system:property and system:shutdown commands. Users with manager role can call system:start-level above , otherwise admin role is required. Also users with viewer role can obtain the current start-level. You can fine tune the command RBAC support by editing the karaf.
It contains the "global" ACL definition. This ACL limits the setStartLevel , start , stop , and update operations for system bundles for only users with admin role. The other operations can be performed by users with the manager role. This ACL limits the change on jmx. This ACL limits the invocation of the canInvoke operation for the users with viewer role.
This ACL limits the changes on jmx. This ACL limits the invocation of the gc operation for only users with the manager role. The Apache Karaf WebConsole is not available by default. To enable it, you have to install the webconsole feature:. All users with the admin role can logon to the WebConsole and perform any operations. The JVM imposes some restrictions about the use of such jars: they have to be signed and be available on the boot classpath.
While this approach works fine, it has a global effect and requires you to configure all your servers accordingly. In addition, you may want to provide access to the classes from those providers from the system bundle so that all bundles can access those. It can be done by modifying the org.
Apache Karaf provides Docker resources allowing you to easily create your own image and container. You can create your own docker image. If you want to build the Karaf image run:. It could be on the same local machine where Apache Karaf instance is running or a remote Docker machine.
In a nutshell, you just have to enable the tcp transport connector for the docker daemon. You have to do it using the -H option on dockerd :.
The docker:images command or images operation on the DockerMBean lists the available images on docker:. The docker:rmi command or rmi operation on the DockerMBean removes an image from docker:. Provisioning is a specific way of creating a container based on the current running Karaf instance: it creates a Docker container using the current running Apache Karaf instance karaf.
You can then reuse this container to create a Docker image and to duplicate the container on another Docker backend via dockerhub.
The docker:top command displays the current running processes in an existing container:. OBR achieves the first goal by providing a service that can automatically install a bundle, with its deployment dependencies, from a bundle repository. This makes it easier for people to experiment with existing bundles.
OBR is an optional Apache Karaf feature. You have to install the obr feature to use OBR service:. It means that Apache Karaf can use a OBR repository for the installation of the bundles, and during the installation of the features.
The OBR repository contains all bundles. Thanks to that, when you install "deploy" in OBR wording a bundle using the OBR service, it looks for all bundles providing the capabilities matching the bundle requirements. It will automatically install the bundles needed for the bundle. If the feature specifies obr in the resolver attribute, Apache Karaf can use the OBR service to construct the list of bundles to install with the features.
The obr:url-add command expects an url argument. You have to reload the repository. Instead of using the URL, you can use the repository index as displayed by the obr:url-list command. To do so, you have to use the -i option:. The obr:list command lists all bundles available on the registered OBR repositories:. The obr:info command displays the details about bundles available on the OBR service.
Especially, it provides details about capabilities and requirements of bundles. It means that you have to use the following command to see the info about the wrapper core bundle with version 4. The obr:source command check the source URL in the OBR metadata for a given bundle, and download the sources on a target folder:. It means that you have to use the following command to download the source of wrapper core bundle with version 4. The obr:resolve command displays the resolution output for a given set of requirements.
Actually, it show the bundles providing the capabilities to match the requirements. Optionally, the obr:resolve command can deploy the bundles as the obr:deploy command does.
For instance, to know the OBR bundle resolving the org. The obr:find command is similar to the obr:resolve one. It displays the bundles resolving the provided requirements, with details. For instance, to find the OBR bundle providing the org. The obr:deploy command installs a bundle from the OBR repository, including all bundles required to satisfy the bundle requirements. By default, the bundles are just installed, not started. You can use the -s option to start the bundles.
It means that you have to use the following command to deploy the wrapper core bundle with version 4. The obr:start command does the same as obr:deploy -s command. It installs the bundle and all required bundles to satisfy the requirements and starts all installed bundles. It means that you have to use the following command to deploy and start the wrapper core bundle with version 4. The Bundles attribute provides a tabular data containing all bundles available on the registered OBR repositories.
The bundles are not automatically started. If start is true , the bundles are automatically started. If deployOptional is true , even the optional requirements will be resolved by the OBR service meaning installing more bundles to satisfy the optional requirements. If you want to use Apache Felix Http Service, you have to install felix-http feature:.
The Pax Web whiteboard extender is an enhancement of the http feature. So use the following command to install:. For commands take a look at the command section in the webcontainer chapter.
The installation of the webconsole feature automatically installs the war feature. The default port used by the WebContainer is Note: the connector is actually bound only when at least a servlet or webapplication is using it. However note that this is not a good idea from a security point of view.
The first step is to create a keystore containing a server certificate. For instance the following command creates a keystore with a self-signed certificate:. By default, Apache Karaf bind these ports on all network interfaces 0. You can config the host property to bind on a specific network interface with a given IP address.
Bundle-ManifestVersion: 2 defines that the bundle follows the rules of R4 specification. Bundle-SymbolicName specifies a unique, non-localizable name for the bundle. This name should be based on the reverse domain name convention. WAB can be deployed directly in Apache Karaf, for instance, by dropping the archive in the deploy folder, or using the bundle:install command.
For instance, the Apache Karaf manual documentation is available as a WAB that you can deploy directly in a running instance:. It allows you to expose remote web applications in Karaf. You can use the Karaf ProxyService programmatically, or via the corresponding shell commands and MBeans.
The State is the current state of the Servlet Deployed or Undeployed. For instance, if you installed the Apache Karaf manual WAR file as described previously, you can see it with web:list :. The web:stop command stops a web application in the WebContainer. The web:stop command expects a id argument corresponding to the bundle ID as displayed by the web:list command. The web:start command starts a web application in the WebContainer.
The web:start command expects a id argument corresponding to the bundle ID as displayed by the web:list command. The http:proxy-add registers a new HTTP proxy. By default, two balancing policies are available: random selecting one URL randomly and round-robin selecting one URL after another one.
You can see the balancing policies available using http:proxy-balancing-list command:. The Servlets attribute provides a tabular data providing the list of deployed Servlets including:. State is the current Servlet state Deployed or Undeployed. The ProxyBalacingPolicies attribute provides the collection of balancing policies available.
The WebBundles attribute provides a tabular data providing the list of deployed Web Applications including:. The OSGi service registry can be viewed as an example of such a system. Apache Karaf also supports regular JNDI, including a directoy system where you can register name bindings, sub-context, etc. The jndi:names command lists all JNDI names. The jndi:names command accepts an optional context argument to list names on the given context. The jndi:names lists only names the full qualified name.
It means that the empty JNDI sub-contexts are not displayed. To display all JNDI sub-contexts empty or not , you can use the jndi:contexts command. However, the transaction feature is installed as a transitive dependency when installing enterprise features like jdbc or jms features for instance. The installation of the transaction feature installs a new configuration: org. A recoverable resource is a transactional object whose state is saved to stable storage if the transaction is committed, and whose state can be reset to what it was at the beginning of the transaction if the transaction is rolled back.
At commit time, the transaction manager uses the two-phase XA protocol when communicating with the recoverable resource to ensure transactional integrity when more than one recoverable resource is involved in the transaction being committed. Transactional databases and message brokers like Apache ActiveMQ are examples of recoverable resources.
A recoverable resource is represented using the javax. If a transaction has a lifetime longer than this timeout a transaction exception is raised and the transaction is rollbacked. Default is 10 minutes.
Combined with the aries. The transaction feature defines the configuration in memory by default. It means that changes that you can do will be lost in case of Apache Karaf restart. The jdbc:ds-factories command lists the available datasource factories, with the available driver. For instance, once you installed the jdbc feature, you can install pax-jdbc-postgresql feature, providing the PostgreSQL datasource factory:.
You can see there the JDBC driver name and class that you can use in the jdbc:ds-create command. The jdbc:ds-create command automatically creates a datasource definition file by leveraging pax-jdbc. Another example using PostgreSQL driver class name you can find with jdbc:ds-factories command :. The jdbc:ds-info command provides details about a JDBC datasource.
The data source may be specified using name or service. Typically, you can use the jdbc:execute command to create tables, insert values into tables, etc. The jdbc:query command is similar to the jdbc:execute one but it displays the query result. It automatically creates a blueprint XML file in the deploy folder containing the JMS connection factory definition corresponding to the type that you mentioned. Currently only activemq and webspheremq types are supported.
It allows you to define the pooling framework you want to use: pooledjms, narayana, transx. In the previous example, we assume that you previously installed the activemq-broker feature. The connectionfactory-test. The jms:delete command deletes a JMS connection factory. The name argument is the name that you used at creation time:. If the JMS broker requires authentication, you can use the -u --username and -p --password options.
Depending of the JMS connection factory type, this command may not work. For now, the command works only with Apache ActiveMQ. For instance, to send a message containing Hello World in the MyQueue queue, you can do:. If you want to consume only some messages, you can define a selector using the -s --selector option. The jms:consume command just consumes so removes messages from a JMS queue. If you want to see the details of messages, you can use the jms:browse command.
By default, the messages properties are not displayed. You can use the -v --verbose option to display the properties:. If you want to browse only some messages, you can define a selector using the -s --selector option. If the JMS broker requires an authentication, you can use the -u --username and -p --password options. The jms:move command consumes all messages from a JMS queue and send it to another one.
For instance, to move all messages from MyQueue queue to AnotherQueue queue, you can do:. The Connectionfactories attribute provides the list of all JMS connection factories names. Apache OpenJPA. The hibernate feature installs the jpa feature with the Hibernate persistence engine:. The eclipselink feature installs the jpa featue with the ElipseLink persistence engine:.
By default, the feature:repo-add openejb command will install the latest OpenEJB version available. However, this project is now "deprecated", and all resources from KarafEE will move directly to Apache Karaf soon. See the developer guide for that. You just have to install the feature corresponding to the CDI container and version that you want to use. Apache Karaf natively provides a failover mechanism. Karaf provides failover capability using either a simple lock file or a JDBC locking mechanism.
In both cases, a container-level lock system allows bundles to be preloaded into the slave Karaf instance in order to provide faster failover performance. This container-level lock system allows bundles installed on the master to be preloaded on the slave, in order to provide faster failover performance.
When a first instance starts, if the lock is available, it takes the lock and become the master. If a second instance starts, it tries to acquire the lock. As the lock is already hold by the master, the instance becomes a slave, in standby mode not active.
A slave periodically check if the lock has been released or not. The Apache Karaf instances share a lock on the filesystem.
Here, we use the filesystem lock. All instances have to share the same lock. The master instance holds the lock by locking a table in the database. If the master loses the lock, a waiting slave gains access to the locking table, acquire the lock on the table and starts. The JDBC driver to use is the one corresponding to the database used for the locking system. Another possible cause of this problem could be that you are trying to run the script in a "user directory" from the the UserDir module.
Running PHP scripts in user directories is disabled by default. You must comment or delete the tag block at the bottom that reads. My case was a little different. I upgraded from Ubuntu While upgration it installed php 7. With 2 versions installed a2query -m php7.
