The UI cannot be opened after a single Management Node starts. How do I resolve this?

Symptom

The UI cannot be opened and a permission denied error appears.

Cause

The permissions on the Management Node configuration file are incorrect.

Solution

• Log in to the Management Node and run the following command to change the owner group of zstack.properties to zstack.

  [root@localhost ~]#  chown  zstack:zstack  /usr/local/zstack/apache-tomcat/webapps/zstack/WEB-INF/classes/zstack.properties
