Therefore, create a manager.xml

# Cat/usr/local/tomcat/conf/catalina/localhost/manager.xml<context privileged= "true" antiResourceLocking= " False "         docbase=" ${catalina.home}/webapps/manager ">  <valve classname=" Org.apache.catalina.valves.RemoteAddrValve "         allow=" ^.* "/></context>

Similarly, if we want to access host Manager, we need to create host-manager.xml

# Cat/usr/local/tomcat/conf/catalina/localhost/host-manager.xml <context privileged= "true" antiResourceLocking= "False"         docbase= "${catalina.home}/webapps/host-manager" >  <valve classname= " Org.apache.catalina.valves.RemoteAddrValve "         allow=" ^.* "/></context>

Finally, we need to modify the Tomcat-users.xml

  <role rolename= "Manager-gui"/>     #对应的角色  <role rolename= "Admin-gui"/>          #对应的角色  <user Username= "Tomcat" password= "Tomcat" roles= "Manager-gui,admin-gui"/>   #用户密码tomcat, password tomcat, with Manager-gui, Admin-gui role

After rebooting tomcat, we can use the above account password to access these three pages
