不出意外的话，tomcat虽然可以正常访问，但是，我们无法进入图形化管理后台，这个还需要另外配置

[root@localhost ~]# cd apache-tomcat-9.0.2/conf/
[root@localhost conf]# ls
Catalina catalina.policy catalina.properties context.xml jaspic-providers.xml jaspic-providers.xsd logging.properties server.xml tomcat-users.xml tomcat-users.xsd web.xml

配置tomcat-users.xml文件，在该文件末尾增加以下内容

<role rolename="manager-gui"/>
<user username="tomcat" password="123456" roles="manager-gui"/>

除此之外还需要配置

[root@localhost META-INF]# pwd
/root/apache-tomcat-9.0.2/webapps/manager/META-INF
[root@localhost META-INF]# ls
context.xml
[root@localhost META-INF]# cat context.xml
<?xml version="1.0" encoding="UTF-8"?>

最后重启，就可以进入tomcat的server status了，用户名为tomcat，密码123456

tomcat网站目录位于apache-tomcat-9.0.2/webapps/ROOT目录下
