使用crontab将tomcat日志自动分割


使用cronolog进行日志切割
1、下载(最新版本)
# wget http://cronolog.org/download/cronolog-1.6.2.tar.gz
2、解压缩
# tar zxvf cronolog-1.6.2.tar.gz
3、进入cronolog安装文件所在目录 
# cd cronolog-1.6.2
4、运行安装 
# ./configure 
# make
# make install
5.进入Tomcat的bin目录,打开catalina.sh文件 ,找到tomcat启动的相关行,或者你直接查找catalina.out,一般我们修改下面行中的内容(因为我们一般不会在-security条件下运行), 

将:

if [ -z "$CATALINA_OUT" ] ; then

  CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out

fi


修改为:

if [ -z "$CATALINA_OUT" ] ; then

  CATALINA_OUT="$CATALINA_BASE"/logs/catalina.%Y-%m-%d.log

fi


将:touch "$CATALINA_OUT"注释掉

#touch "$CATALINA_OUT"


将:

    shift

    "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

      -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \

      -Djava.security.manager \

      -Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \

      -Dcatalina.base="$CATALINA_BASE" \

      -Dcatalina.home="$CATALINA_HOME" \

      -Djava.io.tmpdir="$CATALINA_TMPDIR" \

      org.apache.catalina.startup.Bootstrap "$@" start \

      >> "$CATALINA_OUT" 2>&1 &

修改为:

    "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

      -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \

      -Djava.security.manager \

      -Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \

      -Dcatalina.base="$CATALINA_BASE" \

      -Dcatalina.home="$CATALINA_HOME" \

      -Djava.io.tmpdir="$CATALINA_TMPDIR" \

      org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \

 |/usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null &


将:

  else

    "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

      -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \

      -Dcatalina.base="$CATALINA_BASE" \

      -Dcatalina.home="$CATALINA_HOME" \

      -Djava.io.tmpdir="$CATALINA_TMPDIR" \

      org.apache.catalina.startup.Bootstrap "$@" start \

      >> "$CATALINA_OUT" 2>&1 &

修改为:

  else

    "$_RUNJAVA" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

      -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \

      -Dcatalina.base="$CATALINA_BASE" \

      -Dcatalina.home="$CATALINA_HOME" \

      -Djava.io.tmpdir="$CATALINA_TMPDIR" \

  org.apache.catalina.startup.Bootstrap "$@" start 2>&1 \

  |/usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null &


6.修改完重启tomcat服务即可
