在开发/测试环境，日志是非常重要的。而公司对于测试环境进行了控制，只有配置人员能连接访问，而开发人员是无法获取该服务器的信息的。在出现错误时，没有异常日志，开发是很难重现问题的。因此需要对中间件 tomcat 进行配置，将日志放到某个目录下，开发人员可以通过浏览器就能查看日志。ok，开工：

目的： 能通过浏览器检查tomcat日志

方法：将 tomcat 的日志放置到 $CATALINA_HOME/webapps/ROOT/logs 下，用户就可以通过 http://xxx.xxx.xxx.xxx/logs/catalina.out 访问日志了。

1. 修改tomcat/conf下的logging.properties

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO

# For example, to log debug messages in ContextConfig and HostConfig

# classes and to log only warnings and errors in other

# org.apache.catalina.** classes, uncomment these lines:

#org.apache.catalina.startup.ContextConfig.level = FINE

#org.apache.catalina.startup.HostConfig.level = FINE

#org.apache.catalina.level = WARNING

2. 修改tomcat/bin/catalina.sh

186 if [ -z "$CATALINA_OUT" ] ; then

187   CATALINA_OUT="$CATALINA_BASE"/webapps/ROOT/logs/catalina.out

188 fi

　　

【注意】红色字体是需要修改的内容，修改为当前 tomcat 的最新的网站根目录即可。

3、重启 tomcat

4、使用浏览器即可查看日志： http://xxx.xxx.xxx.xxxx/logs/catalina.out
