How can I install cronolog in Tomcat for daily log rotate?

Question

When i wanted to lotate log daily, I was editing catalina.sh in other to redirect log to cronolog.

I think it is bad solution because catalina.sh file is executable shell file.

Can I config it using editing properties or any files in conf directory ?

Is there another good solution?

new:

      org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \
      | cronolog "$CATALINA_BASE"/logs/catalina.
%Y-%m-%d.out >> /dev/null &

old:

      org.apache.catalina.startup.Bootstrap "$@" start \
      >> "$CATALINA_BASE"/logs/catalina.out 2>&1 &

Answer 1

Why not use a proper logging framework instead of System.out? You have at least three at your disposal:

• java.util.logging and use the RollingFileHandler from http://www.x4juli.org/
• Log4j and use DailyRollingFileAppender
• Logback and use RollingFileAppender

Using any of these you will be able to control what you log (using levels - debug, info, warn, error), where you log (turn loggers on and off) and log into different targets - files, db, mail, jms etc.

Answer 2

David Rabinowitz makes a good point, but to answer your question, your use of cronolog is fine.
