设置log rotation避免tomcat catalina.out文件增长过大

创建logrotate配置文件

?

1	$ vi /etc/logrotate.d/tomcat

 

添加以下内容：

?

1 2 3 4 5 6 7 8 9

/opt/tomcat/logs/catalina.out {    copytruncate    daily    rotate 7   compress    missingok    dateext   size 100m  }

 

参数说明：

?

1 2 3 4 5 6 7 8

specify the path to the log file. copytruncate – creates a copy of the log file and then truncates the original to an empty file so that the service can keep on logging uninterrupted. daily – rotates the catalina.out daily. rotate – keeps at most 7 log files. compress – create a gzip compressed file of the rotated files. missingok – suppresses error messages if the file does not exist. dateext – add the date to the filename of the archived log file. size – rotates if the size of catalina.out is bigger than 100m.

　　

在大多数linux系统上都可以找到文件：/etc/cron.daily/logrotate，该文件每天都会被运行。运行时会调用：

?

1	/usr/sbin/logrotate /etc/logrotate.conf

这样就会rotate掉tomcat的日志。
如果有多个tomcat实例，就需要配置多个单独的rotation文件。

 

也可以手动编写定时任务：

?

1	2 * * * * /usr/sbin/logrotate /etc/logrotate.d/tomcat

　　

也可以顺便将tomcat的临时文件删除掉：

?

1 2 3 4 5 6 7 8 9 10 11 12

/opt/tomcat/logs/catalina.out {    notifempty   copytruncate   dateext   daily   rotate 10   compress   missingok   postrotate     /bin/nice /usr/bin/find /opt/tomcat/temp -type f -mtime +10 -exec /bin/rm {} \; > /dev/null   endscript }
