Cronolog日志分割工具

下载安装Cronolog

wget http://rpmfind.net/linux/epel/7/x86_64/Packages/c/cronolog-1.6.2-14.el7.x86_64.rpm
rpm -Uvh cronolog-1.6.2-14.el7.x86_64.rpm

#验证cronolog安装路径
which cronolog             
/sbin/cronolog

Tomcat日志分割(一)

在Tomcat下bin/catalina.sh文件中添加以下字段

CATALINA_OUT_CMD="cronolog $CATALINA_BASE/logs/catalina.%Y-%m-%d.out >/dev/null 2>&1"

然后重新启动tomcat，查看日志文件格式

Tomcat日志分割(二)

1）修改Tomcat下bin/catalina.sh文件

cp -rf catalina.sh catalina.sh.default

2）修改为以下

450 # touch "$CATALINA_OUT" 
451   if [ "$1" = "-security" ] ; then
452     if [ $have_tty -eq 1 ]; then
453       echo "Using Security Manager"
454     fi
455     shift
456     eval $_NOHUP "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
457       -D$ENDORSED_PROP="\"$JAVA_ENDORSED_DIRS\"" \
458       -classpath "\"$CLASSPATH\"" \
459       -Djava.security.manager \
460       -Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \
461       -Dcatalina.base="\"$CATALINA_BASE\"" \
462       -Dcatalina.home="\"$CATALINA_HOME\"" \
463       -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
464       org.apache.catalina.startup.Bootstrap "$@" start 2>&1\
465       | /sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null &
466 
467   else
468     eval $_NOHUP "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
469       -D$ENDORSED_PROP="\"$JAVA_ENDORSED_DIRS\"" \
470       -classpath "\"$CLASSPATH\"" \
471       -Dcatalina.base="\"$CATALINA_BASE\"" \
472       -Dcatalina.home="\"$CATALINA_HOME\"" \
473       -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
474       org.apache.catalina.startup.Bootstrap "$@" start 2>&1\
475       | /sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-%d.out >> /dev/null &
476 
477   fi

修改成功后，重启Tomcat，然后去看tomcat日志格式
