4.3. Configuring the JBoss Web Server Installation

Some configuration is required before running Red Hat JBoss Web Server. This section includes the following configuration procedures:

Procedure 4.4. Running the Post-Installation Scripts

  1. Open a shell prompt, and change directory to JWS_HOME/etc.
  2. Issue the following commands to run the post-installation scripts:
    sh .postinstall.httpd
    sh .postinstall.tomcat
    
    The post-installation scripts create the Apache and Tomcat users and groups.

Procedure 4.5. Setting the JAVA_HOME Environment Variable

You must set the JAVA_HOME environment variable for Tomcat before running JBoss Web Server.
  1. Open the Tomcat configuration file:
    • For Tomcat 7: JWS_HOME/etc/sysconfig/tomcat7
    • For Tomcat 8: JWS_HOME/etc/sysconfig/tomcat8
  2. Remove the hash (#) sign at the beginning of the following line:
    # JAVA_HOME="/usr/java"

Procedure 4.6. Removing/Re-Adding SSL Support

JBoss Web Server supports SSL by default, but it can be removed. Follow this procedure to remove or re-add SSL support.
  • Go to JWS_HOME/etc/httpd/conf.d and rename the SSL configuration file:
    • To remove SSL, rename ssl.conf to ssl.conf.disabled.
    • To re-add the SSL, rename ssl.conf.disabled to ssl.conf.

Procedure 4.7. Enabling log4j Logging for Tomcat

If required, follow this procedure to add log4j logging to Tomcat.
  1. Open a shell prompt and change directory to JWS_HOME/share/extras/.
  2. Copy the log4j-eap6.jar, log4j.properties, and tomcat-juli-adapters.jar files to the lib directory of the Tomcat directory.
    For example:
    extras]# cp log4j.properties ../tomcat<VERSION>/lib/
    extras]# cp log4j-eap6.jar ../tomcat<VERSION>/lib/
    extras]# cp tomcat-juli-adapters.jar ../tomcat<VERSION>/lib/
    Replace <VERSION> with the respective Tomcat version number (7 or 8).
  3. Replace tomcat-juli.jar file in your Tomcat bin directory with the tomcat-juli.jar file from JWS_HOME/share/extras/:
    extras]# cp tomcat-juli.jar ../tomcat<VERSION>/bin/

Procedure 4.8. Configuring mod_jk

If required, you can configure Apache HTTP Server to use mod_jk as its load balancer.
The steps below list the locations of the mod_jk configuration files. For detailed mod_jk configuration instructions, see the Configure Load Balancing Using Apache HTTP Server and mod_jk section of the HTTP Connectors and Load Balancing Guide.

Note

Sample configuration files are provided for mod_jk, and are located in JWS_HOME/etc/httpd/conf.d/. The sample configuration files are: mod_jk.conf.sample, workers.properties.sample, and uriworkermap.properties.sample. To use these samples instead of creating your own configuration files, remove the .sample extension, and modify their content as needed.
  1. In JWS_HOME/etc/httpd/conf.d/, create a file named workers.properties.
    This file should contain the available workers (JBoss instances).
  2. In JWS_HOME/etc/httpd/conf.d/, create a file named mod_jk.conf.
    This file contains general mod_jk configuration.
  3. In JWS_HOME/etc/httpd/conf.d/, create a file named uriworkermap.properties.
    This file contains request mapping rules that map requests to workers.

Procedure 4.9. Configuring Apache HTTP Server to Use mod_cluster

  • mod_cluster can be configured in JWS_HOME/httpd/conf.d/mod_cluster.conf.
    For more information about customizing mod_cluster, see the mod_cluster Connector section of the HTTP Connectors and Load Balancing Guide.
