Hi,
Two things are to do (description below on Unix/Linux) :
To rotate tomcat logs
To purge files older than x days
1) To rotate tomcat logs
- Put this file (attached) log.rotate (c) Copyright 2004 Steven P Kneizys into the logs directory of your java application instance under Tomcat. This script is in Perl (verify that /usr/bin/perl is well the path of Perl language on the server)
- Set the file executable (chmod +x command line for example)
- Modify le file catalina.sh of your Tomcat distribution directory /opt/app/<tomcat-distrib>/bin/catalina.sh replacing 2 time the line (for Tomcat 6.0.x or higher)
>> "$CATALINA_BASE"/logs/catalina.out 2>&1 &
by these 2 lines (no space after "\")
2>&1 | "$CATALINA_BASE"/logs/rmo.log.rotate \
"$CATALINA_BASE"/logs/catalina.out.%Y-%M-%D.log &
- Stop the application ./run.sh stop <instance-name> (verify that the process is well stopped, otherwise kill it)
- Remove the old file catalina.out
- Start the application ./run.sh start <instance-name>
- Tomcat create again an empty catalina.out file on every start, and this file is not touch after. Its modification date is the date of the last start of tomcat. The rotated log files look like catalina.out_log.2013-08-13.txt
Info : on standalone installations, even if a rotation is in place for atlassian logs, catalina.out is filled. To activate the rotation, modify the file /opt/app/atlassian-standalone-appli/apache-tomcat/bin/catalina.sh
2) To purge files older than x days
- Put this file (attached) log.purge (c) Copyright 2004 Steven P Kneizys into the logs or save directory to purge. This script is in Perl (verify that /usr/bin/perl is well the path of Perl language on the server)
- Set the file executable (chmod +x command line for example)
- To manually purge the logs more than 10 days, into to logs directory, you can use the command line below
./log.purge "." 10 "(catalina.2)(.)*(.log$)"
- To automate it, set a daily cron entry at 1:05am, for instance
Login as <tt>root</tt>
Edit the crontab file crontab -e
Add the line below (set your proper path and file name regex of logs or files to purge)
5 1 * * * su - app -c 'cd /opt/app/tomcat/jira/logs; ./rmo.log.purge "." 10 "(catalina.out.2)(.)*(.log$)" >/dev/null 2>&1'
Save it
- A cron line must be created for every directory where a log.purge file must run
- Example for Crowd standalone
5 1 * * * su - app -c 'cd /opt/app/atlassian-crowd-2.3.4/apache-tomcat/logs; \
./rmo.log.purge "." 10 "(catalina.2)(.)*(.log$)" >/dev/null 2>&1'
5 1 * * * su - app -c 'cd /opt/app/atlassian-crowd-2.3.4/apache-tomcat/logs; \
./rmo.log.purge "." 10 "(manager.2)(.)*(.log$)" >/dev/null 2>&1'
5 1 * * * su - app -c 'cd /opt/app/atlassian-crowd-2.3.4/apache-tomcat/logs; \
./rmo.log.purge "." 10 "(localhost.2)(.)*(.log$)" >/dev/null 2>&1'
Hope that will help you, best regards.
