Installing an Agent on Multiple Servers (with the Different Server Accounts and Passwords)

You can install the agent on multiple servers with different accounts and passwords.

Constraints

• Currently, HSS agents can be installed on a batch of Linux servers running different accounts and passwords on the cloud.
• All servers you want to batch install the agent must be in the same security group or security groups that are connected to each other.

Prerequisites

• All target servers must support SSH login.
• The correct login accounts, port numbers, and passwords of all servers have been obtained.
• All target servers must be in the Running state.

Procedure

1. Log in to the management console.
2. Click in the upper left corner of the page, select a region, and choose Security > Host Security Service.
3. In the navigation pane, choose Installation & Configuration. Click the Agents tab.
4. Click Installation Guide and copy the batch installation command.
5. Remotely log in to the server where you plan to install the agent.
   

   After logging in to the server, run the following command to check whether the expected command exists on the server. If the expected command does not exist, configure the yum repository.

   /bin/expect -v

6. Run the following command to access the /tmp directory:

   cd /tmp/

7. Run the following command to create the linux-host-list.txt file and add the private IP addresses of the servers you want to install the agent to the file:

   Command format: echo "IP address Portroot rootPassword" >> linux-host-list.txt

   Or echo "IP address Port user userPassword rootPassword" >> linux-host-list.txt

   Example: echo "127.8.10.8 22 root rootPassword" >> linux-host-list.txt

   Or echo "127.8.10.9 22 user userPassword rootPassword" >> linux-host-list.txt

   To specify multiple IP addresses, write multiple commands, each in a separate line.

   Example: echo "127.8.10.1 22 root rootPassword" >> linux-host-list.txt

   echo "127.8.10.8 22 user userPassword rootPassword" >> linux-host-list.txt

   echo "127.8.10.3 22 root rootPassword" >> linux-host-list.txt

8. Press Enter to save the IP address. Run the cat linux-host-list.txt command to verify the IP addresses have been added.
9. Paste the copied installation command and run it as user root to install the agent on the servers.

   If information similar to the following is displayed, the agent is successfully installed:

   remote_install finished. [OK]

10. After the installation is successful, choose Installation and Configuration > Agents > Online and check the agent status of the target server. If the agent is online, the Agent is running properly.
