Tomcat日志 ls /usr/local/tomcat/logs 其中catalina开头的日志为tomcat的综合日志，他记录tomcat服务相关信息，也会记录错误日志 其中catalina.日期.log和catalina.out内容相同，前者会每天生成一个新的日志 host-manager和manager为管理相关的日志，其中host-manager为虚拟主机的管理日志 localhost和localhost_access为虚拟主机相关日志，其中带access字样的日志为访问日志，不带access字样的为默认虚拟主机的错误日志 访问日志默认不会生成，需要server.xml中配置一下

[root@localhost ~]# ls /usr/local/tomcat/logs/ catalina.2018-01-17.log host-manager.2018-01-17.log localhost.2018-01-21.log manager.2018-01-17.log catalina.2018-01-21.log host-manager.2018-01-21.log localhost_access_log.2018-01-17.txt manager.2018-01-21.log catalina.out localhost.2018-01-17.log localhost_access_log.2018-01-21.txt [root@localhost ~]# cd !$ cd /usr/local/tomcat/logs/
