安装cronolog
官网下载：http://cronolog.org/usage.html
./configuremake;make install
或者
yum install cronolog -y
默认安装位置：
# which cronolog/usr/local/sbin/cronolog
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/tomcatUsing CATALINA_HOME: /usr/local/tomcatUsing CATALINA_TMPDIR: /usr/local/tomcat/tempUsing JRE_HOME: /usr/java/jdk1.6.0_29Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar[root@VM tomcat]# bin/startup.sh Using CATALINA_BASE: /usr/local/tomcatUsing CATALINA_HOME: /usr/local/tomcatUsing CATALINA_TMPDIR: /usr/local/tomcat/tempUsing JRE_HOME: /usr/java/jdk1.6.0_29Using 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.20140730.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。
