What Should I Do If I Don't See the VM Agent After Installing It?

Symptom

After the agent is installed on the VM, the message "Install agent success!" is displayed.

However, Agent Status indicates that the agent is still missing and to install it first.

Solution

1. Log in to the ECS where the VM agent is offline. For details, see Logging In to an ECS.
2. Run the following commands to check Authorization Model selected during the VM agent installation.

   cd /opt/servicestage-agent

   cat servicestage-agent.conf

   • If the returned AK and SK values are empty, Authorization Model is Agency. Then, go to 3.
   • If the returned AK and SK values are not empty, Authorization Model is AKSK. Go to 4.

3. If Authorization Model is Agency:
   1. Log in to the cloud server console.
   2. Choose Elastic Cloud Server and click the ECS whose VM agent is offline.
   3. In the Management Information area of the Basic Information tab page, view the IAM agency bound to the ECS.
   4. Log in to the Identity and Access Management (IAM) console.
   5. Choose Agencies and click the agency obtained in 3.c.
      1. On the Basic Information tab page, check whether Cloud Service is ECS.
      2. On the Permissions tab page, check whether the permission is Tenant Administrator.

      If both are yes, go to 5.

      If either is no, modify an agency and go to 3.f.

   6. Log in to the ECS where the VM agent is offline. For details, see Logging In to an ECS.
   7. Run the following commands to restart the agent. Replace x.x.x with the version of servicestage-agent in the actual environment.

      cd /opt/servicestage-agent/servicestage-agent-x.x.x

      su agent ./servicestage-agent.sh start

   8. Check whether the agent is online.
      • If yes, no further operation is required.
      • If no, go to 5.

4. If Authorization Model is AKSK, perform the following operations:
   1. Obtain the AK or SK with the correct permissions or create new AK or SK. For details, see Access Keys.
   2. Log in to the ECS where the VM agent is offline. For details, see Logging In to an ECS.
   3. Run the following commands to change the AK and SK values in the configuration file, and save and exit the file.

      cd /opt/servicestage-agent

      vi servicestage-agent.conf

   4. Run the following commands to restart the agent. Replace x.x.x with the version of servicestage-agent in the actual environment.

      cd /opt/servicestage-agent/servicestage-agent-x.x.x

      su agent ./servicestage-agent.sh start

   5. Check whether the agent is online.
      • If yes, no further operation is required.
      • If no, go to 5.

5. If the fault persists, contact customer service.
