Adding a second Tomcat instance to an existing Apache-Tomcat config
- In workers.properties,
- add another worker. The first one is probably 'ajp13' on port 8009. Pick a different name and port.
worker.ajp13inf.port=8109
worker.ajp13inf.host=localhost
worker.ajp13inf.type=ajp13
- add the worker to the list:
worker.list=ajp13, ajp13inf
- In the second Tomcat's server.xml
- tell it to generate mod_jk.conf with the new worker name:
<Listener className="org.apache.ajp.tomcat4.config.ApacheConfig"
modJk="/path/to/apache/modules/mod_jk.so"
workersConfig="/path/to/apache/conf/workers.properties"
jkLog="/path/to/tomcat2/logs/mod_jk.log"
jkDebug="info"
jkWorker="ajp13inf"/>
- and define the Connector using the same port you used in worker.properties
<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8109 -->
<Connector port="8109"
enableLookups="false" redirectPort="8073" debug="0"
protocol="AJP/1.3" />
- In httpd.conf,
- Add the second auto-generated mod_jk.conf file
<IfModule !mod_jk.c>
LoadModule jk_module /path/to/apache/modules/mod_jk.so
</IfModule>
JkWorkersFile /path/to/apache/conf/workers.properties
Include /path/to/tomcat/conf/auto/mod_jk.conf
Include /path/to/tomcat2/conf/auto/mod_jk.conf
- If you're using SSL, add the new contexts to ssl.conf:
Alias /newapp "/path/to/tomcat2/webapps/newapp"
<Directory "/path/to/tomcat2/webapps/newapp">
SSLOptions +StdEnvVars +ExportCertData
Options Indexes FollowSymLinks
</Directory>
JkMount /newapp/* ajp13inf
<Location "/newapp/WEB-INF/">
AllowOverride None
Deny from all
</Location>
