Cronolog 分割 Tomcat日志操作手册

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
需要先杀掉进程：kill -9 1407
修改后，重启tomcat
./ startup.sh
