使用cronolog工具切分Tomcat的catalina.out日志文件
普通用户下载、安装cronolog
[tomcat@localhost ~]$ tar -xf cronolog-1.6.2.tar.gz [tomcat@localhost ~]$ cd cronolog-1.6.2/ [tomcat@localhost cronolog-1.6.2]$ ./configure --prefix=/home/tomcat/cronolog make make install
root用户下下载、安装cronolog
[root@localhost ~]# rpm -qa |grep cronolog [root@localhost ~]# tar zxvf cronolog-1.6.2.tar.gz [root@localhost ~]# cd cronolog-1.6.2 [root@localhost cronolog-1.6.2]# ./configure [root@localhost cronolog-1.6.2]# make && make install [root@localhost cronolog-1.6.2]# which cronolog /usr/local/sbin/cronolog
在普通用户的家目录下编辑.bash_profile文件里添加“$HOME/cronolog/sbin”添加cronolog的安装路径
[tomcat@localhost ~]$ vi .bash_profile
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin:$HOME/cronolog/sbin export PATH
用which cronolog可以查到安装的路径,这个路径待会在修改catalina.sh时会用到。
修改catalina.sh 文件
将186行【CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out】修改成187行【CATALINA_OUT="$CATALINA_BASE"/logs/opres.%Y-%m-%d.out】内容,日志名可以自行定义;
注释掉370行【touch "$CATALINA_OUT"】;
383、384行【
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 "&"】替换成385、386行【
org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \
| /home/tomcat/cronolog/sbin/cronolog "$CATALINA_OUT" >> /dev/null 2>&1 &
】;
396、397行【
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 "&"
】替换成394、395行【
org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \
| /home/tomcat/cronolog/sbin/cronolog "$CATALINA_OUT" >> /dev/null 2>&1 &
】;最后一步(394、395)要注意如果原本的命令只是注释掉,替换的内容一定要在原本内容的上面,不然无法正常启动,前面的替换(383、384)位置没有关系的
97 JAVA_OPTS="-Xms512m -Xmx1024m -Xss1024K -XX:PermSize=256m -XX:MaxPermSize=512m" 98 99 # OS specific support. $var _must_ be set to either true or false. 185 if [ -z "$CATALINA_OUT" ] ; then 186 # CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out 187 CATALINA_OUT="$CATALINA_BASE"/logs/opres.%Y-%m-%d.out 370 #touch "$CATALINA_OUT" 371 if [ "$1" = "-security" ] ; then 372 if [ $have_tty -eq 1 ]; then 373 echo "Using Security Manager" 374 fi 375 shift 376 eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS 377 -Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" 378 -Djava.security.manager 379 -Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" 380 -Dcatalina.base="\"$CATALINA_BASE\"" 381 -Dcatalina.home="\"$CATALINA_HOME\"" 382 -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" 383 # org.apache.catalina.startup.Bootstrap "$@" start 384 # >> "$CATALINA_OUT" 2>&1 "&" 385 org.apache.catalina.startup.Bootstrap "$@" start 2>&1 386 | /home/tomcat/cronolog/sbin/cronolog "$CATALINA_OUT" >> /dev/null 2>&1 & 387 388 else 389 eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS 390 -Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" 391 -Dcatalina.base="\"$CATALINA_BASE\"" 392 -Dcatalina.home="\"$CATALINA_HOME\"" 393 -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" 394 org.apache.catalina.startup.Bootstrap "$@" start 2>&1 395 | /home/tomcat/cronolog/sbin/cronolog "$CATALINA_OUT" >> /dev/null 2>&1 & 396 # org.apache.catalina.startup.Bootstrap "$@" start 397 # >> "$CATALINA_OUT" 2>&1 "&" 398 fi
可以通过./catalina.sh start 来查看配置文件是否正确;这样在/usr/local/tomcat/logs每天会自动生成opres.%Y-%m-%d.out文件,下面我们要做的是定期清理这些过期的文件,我们可以通过crontab来实现
[tomcat@localhost ~]$ crontab -e 30 3 * * * /bin/find /home/tomcat/openapi/logs/ -mtime +7 -type f -name "opres*.*.out" -exec /bin/rm -f {} \; [tomcat@localhost ~]$ crontab -l 30 3 * * * /bin/find /home/tomcat/openapi/logs/ -mtime +7 -type f -name "opres*.*.out" -exec /bin/rm -f {} \;
每天凌晨3点半执行清除7天之前过期日志
