1 、安装cronolog
wget http://down1.chinaunix.net/distfiles/cronolog-1.6.2.tar.gz
./configure
make && sudo make install
默认安装位置:
# which cronolog
/usr/local/sbin/cronolog
2、配置分割Tomcat日志
编辑tomcat目录bin下的catalina.sh文件
# vi bin/catalina.sh
找到下面这行
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_OUT" 2>&1 &
类似这样的行有2处,第一处是tomcat时带“-security”参数的启动,第二处是默认tomcat启动方式,也就是else下面的那部分,我们只修改这里。
另外还要把touch “$CATALINA_OUT"这行注释掉。
完整的修改如下:
# touch "$CATALINA_OUT"
if [ "$1" = "-security" ] ; then
if [ $have_tty -eq 1 ]; then
echo "Using Security Manager"
fi
shift
"$_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 \
>> "$CATALINA_OUT" 2>&1 &
else
"$_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 "$@" start 2>&1 | /usr/local/sbin/cronolog /usr/local/tomcat/logs/catalina.%Y%m%d.out >> /dev/null &
# >> "$CATALINA_OUT" 2>&1 &
fi
保存退出
重启Tomcat服务
[root@VM tomcat]# bin/shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.8.0_23
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar
[root@VM tomcat]# bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jdk1.8.0_23
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar
查看日志目录是否生成catalina.yymmdd.out的日志文件
-rw-r--r-- 1 root root 10537 Jul 30 10:50 catalina.20150527.out
配置cronolog完成了,观察每天是否有一个新的catalina.yymmdd.out的日志文件生成,定期删除日期较旧的日志文件。
