Add support for UTF-8 File system by adding -Dfile.encoding=UTF-8 to the JAVA_OPTS:

JAVA_OPTS="-Xms1024m -Xmx1024m -XX:MaxPermSize=512m $JAVA_OPTS -Djava.awt.headless=true -XX:NewSize=512m -Dfile.encoding=UTF-8"
export JAVA_OPTS

Tweaking of memory and usage comes in play here, I prefer this for a 4 GB Server:

JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MaxPermSize=512m -Djava.awt.headless=true -XX:NewSize=700m -XX:+UseParallelGC -Dsun.rmi.dgc.client.gcInterval=900000 -Dsun.rmi.dgc.server.gcInterval=900000 -XX:+DisableExplicitGC -Dfile.encoding=UTF-8"
export JAVA_OPTS

For saving Garbage Collection in /pack/confluence/logs/gc.log for debugging

JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MaxPermSize=512m -Djava.awt.headless=true -verbose:gc -Xloggc:/pack/confluence/logs/gc.log -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:NewSize=700m -XX:+UseParallelGC -Dsun.rmi.dgc.client.gcInterval=900000 -Dsun.rmi.dgc.server.gcInterval=900000 -XX:+DisableExplicitGC -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/backup/hdump -Dfile.encoding=UTF-8"
export JAVA_OPTS

Binding to a fixed IP Address, add the address= to the connector. Also the port= can be changed (Under Linux only root can bond bind to 0-1023):

<Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8080" address="10.0.0.10" minProcessors="5"
                   maxProcessors="75"
                   enableLookups="false" redirectPort="8443" acceptCount="10" debug="0" connectionTimeout="20000"
                   useURIValidationHack="false" />

...

<Context path="" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true" scheme="https" proxyName="jira.example.com" proxyPort="443">

If the Tomcat needs to travel through symbolic links on the filesystem, add the allowLinking="true" to the context:

<Context path="" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true" allowLinking="true">

I

If the JIRA If the Confluence instance need to run below root /, change the path= parameter:

<Context path="/confluencejira" docBase="../confluence" debug="0" reloadable="false" useHttpOnly="true" allowLinking="true">

Set up logrotate to avoid ever growing catalina.out log file. Here ConfluenceJIRA_Home is /opt/confluencejira, logs are rotated daily and keept for 7 days:

/opt/confluencejira/logs/catalina.out {
    daily
    rotate 7 
    compress
    copytruncate
    delaycompress
    missingok
    size 10M
    notifempty
}
