    Elastic Compute Service:Stop and uninstall Cloud Assistant Agent

    Last Updated:Sep 24, 2025

    Stopping or uninstalling Cloud Assistant Agent disables key remote management features. You will lose access to the following: password-free logon through Session Manager and Workbench, command execution through CloudOps Orchestration Service (OOS), and self-service troubleshooting tools.

    Stop Cloud Assistant Agent

    Important

    If you are connected to the instance using Session Manager or Workbench, stopping the agent terminates your session. Before you proceed, connect to the instance using another method, such as Workbench terminal connection, third-party client tool (SSH), or VNC.

    Linux

    1. Connect to a Linux instance by using a username and password.

    2. Stop the Cloud Assistant daemon process.

      The daemon process monitors and stabilizes Cloud Assistant Agent. If you stop only the main agent service, the daemon process will automatically restart it.
      sudo /usr/local/share/assist-daemon/assist_daemon --stop

    3. Identify the init system type.

      The init system manages services at startup. You need to identify your instance's init system because the commands to manage Cloud Assistant Agent differ for each type.

      • systemd: Alibaba Cloud Linux, CentOS 7+, Red Hat Enterprise Linux (RHEL) 7+, Fedora 15+, Ubuntu 15.04+, Debian 8+, and others.

      • Upstart: Ubuntu 6.10-14.10, RHEL 6, CentOS 6, and others.

      • SysVinit: RHEL 5, CentOS 5, Debian 6, and others.

    4. Stop the Cloud Assistant Agent.

      systemd

      sudo systemctl stop aliyun.service

# Verify that the service has stopped. The service is stopped if the output contains "inactive (dead)".
sudo systemctl status aliyun.service

      Upstart

      sudo /sbin/initctl stop aliyun-service

# Verify that the service has stopped. The service is stopped if the output is empty.
ps aux | grep -v grep | grep "aliyun-service"

      SysVinit

      sudo /etc/init.d/aliyun-service stop

# Verify that the service has stopped. The service is stopped if the output is empty.
ps aux | grep -v grep | grep "aliyun-service"
