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
