Managing the Azure Execution Server

The deployment process of the CloudShell Template deploys a VM on the Azure region called ExecutionServer-VM and in it installs an Execution Server called "Azure-<region>" (for example, "Azure-East US").

Support

• The Execution Server is installed on a Centos 7 VM (CentOS 7.2 and up).
• The Execution Server comes with Python 2.7 and 3 installed and configured out of the box.

Accessing the Execution Server VM

• Use the Admin Username and Admin Password defined in the CloudShell Template that was deployed on the Azure region.

Connecting the Execution Server to Quali Server

This procedure is required if Quali Server is also installed on Azure.

• Log in to the Execution Server machine and follow the instructions in Configure the Linux Execution Server.

Execution Server logs

Execution Server logs reside at:

• /opt/ExecutionServer/logs
• /var/log/qualisystems/

Performing maintenance operations on an Execution Server

Do the following if you need to perform any maintenance operations on the Execution Server, such as updating the Execution Server version of setting customer.config keys:

1. Stop the Execution Server service by running the following command:

   sudo systemctl stop es

2. Perform the maintenance operations.

3. Start the Execution Server service by running the following command:

   sudo systemctl start es

Installing a new Execution Server

Follow this procedure to install a new Execution Server from scratch. To upgrade an existing Execution server, scroll down to the next section.

1. From Quali’s Download Center, download the Linux Execution Server installation script to your local machine.

2. Create a new VM in your region.

3. In the All services window, click Virtual machines.
4. In the Virtual machines blade, click Add.
5. Create a CentOS VM (CentOS 7.2 and up) .
6. In the Settings blade of the new virtual machine, click Extensions.

7. In the Extensions blade, select Add extension and then select Custom Script For Linux.

   

8. In the Custom Script for Linux blade, click Create.

9. In the Install extension blade, set the params:

   • Script files: Browse to the Linux Execution Server installation script file you downloaded.

   • Command: Paste the below line, and set the CloudShell Server and admin credentials.

     sudo sh cloudshell_es_install_script.sh [CloudShellServerIP] [CloudShellServerAdmin] [CloudShellServerAdminPassword] [ExecutionServerName]

     For example:

     sudo sh cloudshell_es_install_script.sh 192.168.52.47 admin admin es-EastUS

     Notes:

     • If the Execution Server VM does not have an internet connection, make sure the OfflinePackageRepository zip file is extracted to the local PyPi Server repository. For details, see Add the out-of-the-box dependencies package to the local PyPi Server repository.

     • Quali Server must be running when configuring the Execution Server.

     • Depending on your flavor of Linux, you may need to escape parameter values containing special characters with single or double quotes. For example: "admin1234!"

10. Click OK on all the blades until you reach the Create blade.
11. Click Create.

Upgrading an existing Execution Server

There are two ways to upgrade the Azure Execution Server:

• Upgrade to a GA version (by running a custom script on the Execution Server VM)
• Upgrade to a non-GA patch version (by replacing configuration DLLs)

To upgrade to a GA version:

1. SSH to the VM.

2. Stop the Execution Server service by running the following command:

   sudo systemctl stop es

3. Run the following script (set the appropriate values):

   curl [InstallScript] --output cloudshell_es_install_script.sh --retry 20 -s -S
   chmod +rwx ./cloudshell_es_install_script.sh
   sed -i -e 's/\r$//' ./cloudshell_es_install_script.sh
   ./cloudshell_es_install_script.sh [CloudShellServerIP] [CloudShellServerAdmin] [CloudShellServerAdminPassword] [ExecutionServerName]

   For example:

   curl https://s3.amazonaws.com/quali-prod-binaries/8.3-168734/ES/cloudshell_es_install_script.sh --output cloudshell_es_install_script.sh --retry 20 -s -S
   chmod +rwx ./cloudshell_es_install_script.sh
   sed -i -e 's/\r$//' ./cloudshell_es_install_script.sh
   ./cloudshell_es_install_script.sh 192.168.42.132 admin admin es-shells

   Notes:

   • If the Execution Server VM does not have an internet connection, make sure the OfflinePackageRepository zip file is extracted to the local PyPi Server repository. For details, see Add the out-of-the-box dependencies package to the local PyPi Server repository.

   • Quali Server must be running when configuring the Execution Server.

   • Depending on your flavor of Linux, you may need to escape parameter values containing special characters with single or double quotes. For example: "admin1234!"

4. Start the Execution Server service by running the following command:

   sudo systemctl start es

   Tip: The Execution Server service name was changed from qa_execution_server to es in version 8.3.

To upgrade to a patch version:

1. Open the CloudShell patch package.

2. Go to the ~\CloudShell <version>\Data\ExecutionServer\Qualisystems\TestShell\ExecutionServer folder. For example:

3. Select all contents in the folder and create a tar archive.
4. Copy the tar file to the /temp folder in the ExecutionServer-VM VM.
5. SSH to the VM.

6. Stop the Execution Server service by running the following command:

   sudo systemctl stop es

7. Extract the tar file to /opt/ExecutionServer, overriding any existing files.

8. Start the Execution Server service by running the following command:

   sudo systemctl start es
