Uninstalling ICAgent

If ICAgent is uninstalled from a host, log collection will be affected. Exercise caution when performing this operation.

Only ICAgent installed on Linux hosts can be uninstalled from the Host Management page of the LTS console. To uninstall ICAgent from a Windows host, go to \ICProbeAgent\bin\manual\win in the directory where the ICAgent installation package was decompressed, and double-click the script named uninstall.bat. If the message ICAgent uninstall success is displayed, the uninstallation was successful.

Uninstalling ICAgent does not delete the installation files. You need to delete them manually if necessary.

There are a number of ways to uninstall ICAgent:

Uninstalling ICAgent on the Console: This can be used to uninstall ICAgent that has been successfully installed.
Uninstalling ICAgent on a Host: This can be used to remove ICAgent that fails to be installed for reinstallation.
Remotely Uninstalling ICAgent: This can be used to remotely uninstall ICAgent that has been successfully installed.
Batch Uninstalling ICAgent: This can be used to uninstall ICAgent that has been successfully installed from a batch of hosts.

Uninstalling ICAgent on the Console

Log in to the LTS console and choose Host Management in the navigation pane on the left.
Click the Hosts tab.
Select one or more hosts where ICAgent is to be uninstalled and click Uninstall ICAgent.
In the displayed dialog box, click OK.
The uninstallation begins. This process takes about a minute.

Once uninstalled, the host will be removed from the host list.

To reinstall ICAgent, wait for 5 minutes after the uninstallation completes, or the reinstalled ICAgent may be unintentionally uninstalled again.

Uninstalling ICAgent on a Host

Log in to a host where ICAgent is to be uninstalled as user root.
Run the following command:
bash /opt/oss/servicemgr/ICAgent/bin/manual/uninstall.sh;

If the message ICAgent uninstall success is displayed, the uninstallation has completed.

Remotely Uninstalling ICAgent

You can uninstall ICAgent on one host remotely from another host.

Run the following command on the host where ICAgent has been installed, x.x.x.x is the IP address of the host you want to uninstall ICAgent from.
bash /opt/oss/servicemgr/ICAgent/bin/remoteUninstall/remote_uninstall.sh -ip x.x.x.x
Enter the password for user root of the host when prompted.
- If the Expect tool is installed on the host that has ICAgent installed, the ICAgent uninstallation should be able to complete without prompting you for a password. Otherwise, enter the password as prompted.
- Ensure that user root can run SSH or SCP commands on the host where ICAgent has been installed to communicate with the remote host to uninstall ICAgent.
- If the message ICAgent uninstall success is displayed, the uninstallation has completed.

Batch Uninstalling ICAgent

If ICAgent has been installed on a host and the ICAgent installation package ICProbeAgent.tar.gz is in the /opt/ICAgent/ directory of the host, you can use this method to uninstall ICAgent from multiple hosts at once.

The hosts must all belong to the same Virtual Private Cloud (VPC) and be on the same subnet.

Prerequisites

The IP addresses and passwords of all hosts to uninstall ICAgent have been collected, sorted in the iplist.cfg file, and uploaded to the /opt/ICAgent/ directory on the host that has ICAgent installed. Each IP address and password in the iplist.cfg file must be separated by a space, as shown in the following example:

192.168.0.109 Password (Replace the IP address and password with the actual ones)

192.168.0.39 Password (Replace the IP address and password with the actual ones)

Because the iplist.cfg file contains sensitive information, you are advised to clear it after using it.

If all hosts share a password, list only IP addresses in the iplist.cfg file and enter the password during execution. If one of the hosts uses a different password, type the password behind its IP address.

Procedure

Run the following command on the host that has ICAgent installed:
bash /opt/oss/servicemgr/ICAgent/bin/remoteUninstall/remote_uninstall.sh -batchModeConfig /opt/ICAgent/iplist.cfg

Enter the default password for user root of the hosts to uninstall ICAgent. If the passwords of all hosts have been configured in the iplist.cfg file, press Enter to skip this step.
```
batch uninstall begin
Please input default passwd:
send cmd to 192.168.0.109
send cmd to 192.168.0.39
2 tasks running, please wait...
End of uninstall agent: 192.168.0.109
End of uninstall agent: 192.168.0.39
All hosts uninstall icagent finish.
```
If the message All hosts uninstall icagent finish. is displayed, the batch uninstallation has completed.
Choose Host Management > Hosts on the LTS console to view the ICAgent status.
