1. Go to the /opt/redhat/ews/share/extras directory.
2. Copy the log4j.jar and log4j.properties files to the lib directory of the Tomcat directory:
   • If using Tomcat 6, run the following commands:

     extras]# cp log4j.jar log4j.properties ../tomcat6/lib

     extras] # cp tomcat-juli-adapters.jar /opt/redhat/ews/share/tomcat6/lib

     Copy to Clipboard Toggle word wrap
   • If using Tomcat 5, run the following commands:

     extras]# cp log4j.properties ../tomcat5/common/classes

     Copy to Clipboard Toggle word wrap

Procedure 5.8. Configuring mod_jk

1. Create a workers.properties file in /opt/rehat/ews/etc/httpd/conf/httpd/conf/ (refer to http://tomcat.apache.org/connectors-doc/reference/apache.html).
2. Create a mod_jk.conf in /opt/rehat/ews/etc/httpd/conf/httpd/conf.d/, (refer to http://tomcat.apache.org/connectors-doc/reference/apache.html).

   Note

   You can also copy and modify the sample files mod_jk.conf.sample and workers.properties.sample available in /opt/rehat/ews/etc/httpd/conf/httpd/conf/: modify their content as needed and rename them to mod_jk.conf and workers.properties.

Procedure 5.9. Configuring mod_cluster

1. From Red Hat Customer Portal, download the jboss-ep-native ZIP file for your operating system and architecture.
2. Unzip the downloaded file.
3. In the location, where you have extracted the file, change to jboss-ep-<VERSION> /native/lib[64]/httpd/modules
4. Run the following command to copy mod_cluster modules to /opt/redhat/ews/lib[64]/httpd/modules:

   modules]# cp mod_advertise.so mod_manager.so mod_proxy_cluster.so mod_slotmem.so -t /usr/lib[64]/httpd/modules

   Copy to Clipboard Toggle word wrap
5. In /opt/redhat/ews/httpd/conf/httpd.conf add a hash (#) sign at the beginning of the following line to disable the mod_proxy_balancer module:

   LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

   Copy to Clipboard Toggle word wrap

   This module is incompatible with the JBoss HTTP Connector.
6. Configure the server to load the JBoss HTTP Connector modules:
   1. Create the file /opt/redhat/ews/httpd/conf.d/JBoss_HTTP.conf.
   2. Add the following lines to the file JBoss_HTTP.conf:

      LoadModule slotmem_module modules/mod_slotmem.so
      LoadModule manager_module modules/mod_manager.so
      LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
      LoadModule advertise_module modules/mod_advertise.so
