tomcat启动报错：LifecycleException: 无法启动组件[org.apache.catalina.webresources.StandardRoot@22807d9a]

一、场景

启动tomcat失败，并且catalina.out出现异常信息

二、报错信息

三、排查

从以下2处报错信息可以看出，启动失败和WEB资源有关

1、无法启动组件[org.apache.catalina.webresources.StandardRoot@22807d9a]

2、Caused by: java.lang.IllegalArgumentException: 指定的主资源集 [/home/xxx/upload] 无效

3、进入tomcat的conf目录，打开server.xml配置文件，查看tomcat配置的静态资源目录

4、确认该目录是否存在

四、原因

tomcat配置的静态资源目录不存在

五、解决

方式1、更改tomcat所配置的静态资源目录，重启tomcat

方式2、新建tomcat所配置的静态资源目录，重启tomcat
