cronolog 工具切分catalina.out

1. 下载cronolog   

解压缩 
    # tar zxvf cronolog-1.6.2.tar.gz 
进入cronolog安装文件所在目录 
    # cd cronolog-1.6.2 
运行安装 
    # ./configure 
    # make 
    # make install

成功后 运行which cronolog会找到对应的路径 /usr/local/sbin/cronolog

2.引入jar包

    log4j-1.2.16.jar 
    tomcat-juli-adapters.jar
    tomcat-juli.jar

3. 找到tomcat/bin/catalina.sh 中修改

org.apache.catalina.startup.Bootstrap “$@” start  \   
>> “$CATALINA_BASE”/logs/catalina.out 2>&1 &  

为

org.apache.catalina.startup.Bootstrap "$@" start \
2>&1 |/usr/local/sbin/cronolog "/logs/apps/tomcat/catalina-%Y-%m-%d.out" &

4.重启tomcat
