The platform cannot be logged in to. How do I resolve this?

Platform login failures generally have the following two causes. Identify the cause and refer to the corresponding solution to troubleshoot:

Cause 1

The management IP in the Management Node configuration file does not match the IP shown in the management service status output.

Solution

1. Connect to the Management Node via SSH.

2. Edit the Management Node configuration file: open /usr/local/zstack/apache-tomcat/webapps/zstack/WEB-INF/classes/zstack.properties and update management.server.ip and any other related IP addresses to the correct values.

3. Run the following command to restart the Management Node service:

   [root@localhost ~]# zstack-ctl stop && zstack-ctl start

4. Log in to the platform again. The login succeeds.

Cause 2

The platform is inaccessible and the host dmesg output shows a Temperature above threshold message, which may indicate abnormal CPU temperature on the host.

Solution

• Check whether the data center air conditioning is functioning properly.

• Check the status of the rack where the host is located.
