Use Cronolog to cut Tomcat logs and delete log records before the specified number of days under Linux

Use the Cronolog tool to slice Tomcat's catalina.out log files

Normal user download, install Cronolog

[[email protected] ~]$ tar-xf cronolog-1.6.2.tar.gz[[email protected] ~]$ CD Cronolog-1.6.2/[[email protected] cronolog- 1.6.2]$./configure--prefix=/home/tomcat/cronologmakemake Install

Root user download, install Cronolog

[Email protected] ~]# Rpm-qa |grep cronolog[[email protected] ~]# tar zxvf cronolog-1.6.2.tar.gz [[email protected] ~]# CD Cronolog-1.6.2[[email protected] cronolog-1.6.2]#./configure [[email protected] cronolog-1.6.2]# make && Make Install[[email protected] cronolog-1.6.2]# which cronolog/usr/local/sbin/cronolog

In the normal user's home directory, edit the. bash_profile file and add "$HOME/cronolog/sbin" to add the Cronolog installation path

[Email protected] ~]$ Vi. bash_profile

# .bash_profile                                                                                                                                                                                        # get the aliases  and functionsif [ -f ~/.bashrc ]; then         . ~/.bashrcfi# user specific environment and startup programspath=$ PATH: $HOME/bin: $HOME/cronolog/sbinexport path

With which cronolog you can find the path to the installation, which will be used when modifying catalina.sh.

Modify the catalina.sh file

Modify the 186 line "catalina_out=" $CATALINA _base "/logs/catalina.out " to 187 lines "catalina_out=" $CATALINA _base "/logs/ Opres.%y-%m-%d.out " content, log name can be defined by itself;

Comment out 370 lines of "touch" $CATALINA _out "";

383, 384 lines "

Org.apache.catalina.startup.Bootstrap "[email protected]" start \

>> "$CATALINA _out" 2>&1 "&" " Replace with 385, 386 lines "

Org.apache.catalina.startup.Bootstrap "[email protected]" Start 2>&1 \

| /home/tomcat/cronolog/sbin/cronolog "$CATALINA _out" >>/dev/null 2>&1 &

";

396, 397 lines "

Org.apache.catalina.startup.Bootstrap "[email protected]" start \

>> "$CATALINA _out" 2>&1 "&"

" Replace with 394, 395 lines "

Org.apache.catalina.startup.Bootstrap "[email protected]" Start 2>&1 \

| /home/tomcat/cronolog/sbin/cronolog "$CATALINA _out" >>/dev/null 2>&1 &

the final step (394, 395) to note that if the original command is only commented out, the content of the replacement must be on the original content, otherwise it will not start normally, the previous replacement (383, 384) position is not related

You can see if the configuration file is correct by using./catalina.sh start, so that the/usr/local/tomcat/logs is automatically generated every day opres.%y-%m-% D.out file, the next thing we do is to regularly clean up these outdated files, we can crontab to achieve

[[email protected] ~]$ CRONTAB-E30 3 * * */bin/find/home/tomcat/openapi/logs/-mtime +7-type f-name "Opres*.*.out"-E xec/bin/rm-f {} \; [Email protected] ~]$ crontab-l 3 * */bin/find/home/tomcat/open api/logs/-mtime +7-type f-name "Opres*.*.out"-exec/bin/rm-f {} \;

7 days before the purge is performed daily 3:30 A.M. the log expires
