默认情况下,tomcat的catalina.out日志文件是没有像其它日志一样,按日期进行分割,而是全部输出全部写入到一个catalina.out,这样日积月累就会造成.out日志越来越大,给管理造成了不便,为了实现像其它日志文件一样按日期归档,这里我们采用cronolog来完成日志分割。
一、安装cronolog
YUM 安装
使用cronolog包实现按日期分割catalina.out日志文件
yum install cronolog
或是 源码安装
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、查看cronolog安装后所在目录(验证安装是否成功)
which cronolog /usr/sbin/cronolog
二、修改bin/catalina.sh文件 标红的为修改的内容,
具体如下:
shift
touch “$CATALINA_OUT”
if [ “$1” = “-security” ] ; then
if [ $have_tty -eq 1 ]; then
echo “Using Security Manager”
fi
shift
eval “\”$_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 \
>> “$CATALINA_OUT” 2>&1 “&”
else
eval “\”$_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 “&”
fi
改为:
shift
# touch “$CATALINA_OUT” 注释掉
if [ “$1” = “-security” ] ; then
if [ $have_tty -eq 1 ]; then
echo “Using Security Manager”
fi
shift
eval “\”$_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/sbin/cronolog “$CATALINA_BASE”/logs/catalina.%Y-%m-%d.out >> /dev/null &
else
eval “\”$_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 “$@” start 2>&1 | /usr/sbin/cronolog “$CATALINA_BASE”/logs/catalina.%Y-%m-%d.out >> /dev/null &
fi
修改后,重启tomcat
