qTest Automation Host 2.x Installation Guide on Linux


In this article, we will walk you through how to install the qTest Automation Host version 2.x on a Linux machine.

Note: This article walks through installing the Automation host on a Linux machine using the recommended Web Interface. There is an advanced installation method that requires you using the command line, e.g. when IT admin want to mass install automation host to multiple machines in the network, refer to this article to learn more about this method.

Download qTest Automation Host 2.x

  1. From the Download Automation Host page, download the qTest Automation Host 2.x for Linux.
    IMPORTANT: It is highly recommended that you download the latest 2.x version to benefit from bug fixes and enhancements.
  2. Open the Terminal.
  3. Copy the downloaded file agentctl-[version]-linux-x64-full.tgz to a desired installation directory, e.g. /usr/local/agentctl-[version]-linux-x64-full.tgz
    • If you plan to install multiple automation host instances on Linux, it is important that you create a parent folder for each instance to easily identity the instance as well to avoid issues when upgrading each instance. The best practice is to suffix parent folder with a number. For EXAMPLE:
      • Instance #1: /usr/local/qtest-automation-host-1/agentctl-[version]-linux-x64-full.tgz
      • Instance #2: /usr/local/qtest-automation-host-2/agentctl-[version]-linux-x64-full.tgz
      • ...
      • Instance #N: /usr/local/qtest-automation-host-N/agentctl-[version]-linux-x64-full.tgz
    • Replace [version] in the command to the actual version that you have chosen to download, e.g. 2.1.1
  4. Change the current directory to the installation directory. For EXAMPLE:
    $ cd /usr/local
    or if you are going to install multiple automation host instances
    $ cd /usr/local/qtest-automation-host-N
  5. Extract the bundle:
    $ tar -zxf agentctl-[version]-linux-x64-full.tgz
  6. Change the current directory to the extracted agentctl:
    $ cd agentctl-[version]

Acquire your qTest API Token

  1. Login to qTest Manager as an Administrator and access the Resources page.
  2. Expand the APIs and SDK section.
  3. Copy the API Token, as shown below:



The token will be automatically changed by qTest Manager if below events occur:

  • Users change their password in qTest Manager OR
  • Users switch authentication type, e.g. from authenticating with qTest using Username and Password to SSO or LDAP, and vice versa

Install and Configure the Automation Host

  1. From the Terminal, execute the following command:
    /path/to/agentctl-[version]$ ./agentctl start
  2. Wait a couple of minutes for the Automation Host to fully start. Open a web browser and navigate to http://localhost:6789. You'll see the registration UI being shown, as below.
  3. Enter information to register the automation host:
    • Host Name: Enter a meaningful name for the host
    • qTest URL: Your qTest Site URL
    • qTest Token: Enter the token from the step Aquire your qTest API token
    • Full Name: Your full name
    • Configure Proxy: If you are connecting to the internet through your corporate proxy, select Enable checkbox to enable proxy configuration
      • Script: If your proxy server is configured with a script, enter the URL to access your PAC (Proxy Auto-Configuration) file
      • Host: Enter the proxy host address. This can be either the IP address, computer name, or dns name of this proxy server. Note: If you specify both Script and Host, the automation host will connect to the script-based proxy server first, then connect to the proxy host if the connection to the script-based one failed.
      • Port: Specify the port that the proxy server is running on. This parameter is required.
      • Username: If your proxy server requires basic authentication, enter a username to authenticate with the proxy. Otherwise, leave this field empty.
      • Password: If your proxy server requires basic authentication, enter a password to authenticate with the proxy. Otherwise, leave this field empty.
    • Run on Start Up: Available on Automation Host 2.2.2 and later. Select this option to automatically start the Automation Host when the machine starts



Select Register to start registering Automation Host with qTest Manager. This process will take a while and once it's finished, you'll be automatically navigated to the home page.

Install the Automation Host as Service on Linux

If you want the Automation Host to automatically start when system starts, there are two options:

  1. Install Automation Host as a service OR
  2. Configure it to run at system start up (highly recommended for Automation Host 2.2.2+). Refer to the previous instructions to learn how to configure Automation Host to automatically start when system starts

Install qTest Automation Host as a single Service on Linux

Notes: if you are using Automation Host 2.1.1 or later AND you want to install multiple instances of Automation Host as services on Linux, skip to next section.

Access the agentctl directory and execute following commands:

1. If the automation host is running in the Terminal, press Ctrl + C to stop it

2. Execute below command to install the automation host as a service:

/path/to/agentctl-[version]$ sudo ./install

3. Check if the service is installed successfully with below command

/path/to/agentctl-[version]$ sudo systemctl status qtest-automation-agent 

Note: It might take some minutes for the service to fully start for the first time. After that, you can access the host UI using your browser.

Install Multiple qTest Automation Host Instances as Services on Linux

Notes: This feature is only available from the Automation Host version 2.1.1 and later.

Follow the steps below if you want to install multiple Automation Host instances as services on Linux.

  1. Extract the downloaded Automation Host package to multiple directories. Make sure you create a parent directory for each automation host instance to easily identify it as well to avoid issues when upgrading that instance. EXAMPLE below shows how we extract each package inside a parent directory whose name is suffixed with a number
    • Instance #1: /usr/local/qtest-automation-host-1/agentctl-[version]
    • Instance #2: /usr/local/qtest-automation-host-2/agentctl-[version]
    • ...
    • Instance #N: /usr/local/qTest-automation-host-N/agentctl-[version]
  2. Access each directory, then perform steps 3-5 for each directory.
  3. Install and Register the Automation Host.
    IMPORTANT: make sure you give each instance a unique Port number via -Pport parameter. It is also highly recommended to give each instance a unique automation host name via -Phostname parameter in config or start command
  4. If the Automation Host is running in Terminal, stop it with below command.
    ./agentctl stop
  5. Execute the command below to install the host as a service:
    IMPORTANT: you must give the service a unique name via <service name> parameter:
    /path/to/agenctl-[version]$ sudo ./install "<service name>"

Uninstall Service

If you want to uninstall the  Automation Host 2.x service, open the Terminal and execute the following commands:

/path/to/agentctl-[version]$ sudo ./uninstall

If you installed multiple instances of automation host as services on Linux, access to each automation host directory and execute the above ./uninstall command.
