tomcat8用log4j配置日志 解决日志过大问题

不想给linux安装插件切割,只想tomcat解决

官方文档参考:https://tomcat.apache.org/tomcat-8.0-doc/logging.html

上面连接有说明怎么用

下方为使用方法找到你的tomcat对应版本

下载地址为:https://archive.apache.org/dist/tomcat/tomcat-8/v8.0.53/bin/extras/

替换掉你本地版本去找下载便可,个人版本是v8.0.53,因此直接改上面版本下载便可

下载tomcat-juli-adapters.jar和tomcat-juli.jar

将tomcat-juli-adapters放到 tomcat目录\lib下

将tomcat-juli放到 tomcat目录\bin下 (切记 切记 切记 是bin目录下)

而后下载log4j的包
下载地址:https://mvnrepository.com/artifact/log4j/log4j

我用的版本是:log4j-1.2.17.jar

将log4j-1.2.17.jar拷贝到 tomcat目录\lib下

删除tomcat自己的logging.properties (在tomcat目录\conf 下面)

建立log4j.properties文件,将文件放到tomcat目录\lib下(注意:不是conf下面)

还须要注意:注释掉catalina.sh里面的这一行

if [ -z "$CATALINA_OUT" ] ; then
  #CATALINA_OUT="$CATALINA_BASE"/logs/catalina.out
  CATALINA_OUT=/dev/null
fi

下面是截图: 位置本身搜索应该就一行
