How do I rotate catalina.out?

CATALINA_BASE/logs/catalina.out does not rotate. But it should not be an issue because nothing should be printing to standard output since you are using a logging package, right?

If you really must rotate catalina.out, here are some techniques you can use:

1. If you are using jsvc 1.0.4 or later (from Apache Commons Daemon project) to launch Tomcat, you can send SIGUSR1 signal to jsvc to get it to re-open its log files (Jira Ticket). You can couple this with ’logrotate’ or your favorite log-rotation utility (including good-old ‘mv’) to re-name catalina.out at intervals and then get jsvc to re-open the original (catalina.out) file and continue writing to it.
2. Use ’logrotate’ with the ‘copytruncate’ option. This allows you to externally rotate catalina.out without changing anything within Tomcat.
3. Modify bin/catalina.sh (or bin/catalina.bat) to pipe output from the JVM into a piped-logger such as cronolog or Apache httpd’s rotatelogs (note that the previous reference is for Apache httpd documentation and is not applicable to Tomcat – it merely illustrates the concept). See also the patch in Bug 53930, “Allow capture of catalina stdout/stderr to a command instead of just a file”.
