You can deploy ScaleArc in one of two ways on GCP:

• Using the public image (from the marketplace)
• Doing a custom install

Marketplace

ScaleArc database load balancing is available on the Google Cloud Platform as a virtual machine (VM) image.  The VM image contains the latest version of ScaleArc optimized for use with Google Cloud Platform Compute Engine. 

Prerequisites

You need the following to get started: 

• Google Cloud Platform account
• SQL Server (Google Cloud Engine) database servers on cloud VMs 
  
  

Installing the ScaleArc VM 

Follow the steps blow to set up a ScaleArc environment on the Google Cloud Platform using Cloud Launcher.

1. Access ScaleArc for MS SQL page in Google Cloud Launcher and click on the Launch On Compute Engine button.
   
   
   
   

2. The Google Developers Console window opens. Create a new VM instance and specify the deployment name, zone, machine type, and boot disk.  
   
   
   
   

   The minimum VM size supported is 4 cores.  

3. In the Firewall section, make sure to Allow HTTP, HTTPS, TCP port 22, and TCP port 3306 traffic check boxes.  

4. Locate Custom metadata > scalearc_user_password. Copy this system-generated password for reuse when you initialize ScaleArc on Google Cloud. 
5. Click the Deploy button. The Google Deployment Manager confirms that ScaleArc was deployed successfully. 
   
   

Log in to ScaleArc

You are now ready to log into ScaleArc.

1. Browse to the IP address to set up ScaleArc.
   
   
   
   
2. A successful network setup brings up the Welcome screen. You are now ready to initialize ScaleArc.
   
   
   
   

Custom install

Prerequisites

You need the following to get started: 

• A Google Cloud Platform account
• MS SQL (Google Cloud Engine) database servers on Cloud VMs 
• ScaleArc 3.12 RPM installer

Deployment Procedure

Since the ScaleArc RPM installer checks for CentOS version, disk, and RAM size, a deprecated version of CentOS from Google Cloud Platform needs to be deployed to expand the disk. Follow the steps below to begin the deployment process.

1. Login to htts://console.developers.google.com using your credential.
2. Scroll down to Compute Engine, click Images, click Show Deprecated Images.
   
   
   
   
3.  Select centos-6-v20170227 and click on Create Instance.
   
   
   
   
4. Fill in the following details.
   
   
   
   
   1. Instance Name
   2. Zone (choose a zone to launch the instance)
   3. Machine type (at a minimum select n1-standard-4)
   4. In the Boot disk pop up screen, select CentOS 6, and set the disk size to 50GB or more
   5. Under Firewall settings, select Allow HTTP and HTTPS traffic
      
      
5. Click Create to complete the VM creation.
6. To SSH directly from your web browser in the Google Cloud Platform Console, go to the VM Instances page. In the list of virtual machine instances, click the SSH button in the row of the instance to which you want to connect.   
   
   
   
   

7.  Run the following from the command line as a sudo user.
   
   

   # rpm -ivh "https://idblb-iso.s3.amazonaws.com/scalearc-3.11.0.2.1/RPMs/idb_installer-3.11.0.2.1-7.x86_64.rpm?AWSAccessKeyId=AKIAIIM5N6CCFZ76RTNQ&Expires=1521950132&Signature=2ELcNYFWHJfTNoyZTugL85JPaSo%3D"

8. The following RPM is installed by default on the Google CentOS image. This RPM is not required and will cause conflicts with the deployment if it is not removed. Remove the RPM from the machine. 

   yum remove augeas-libs

   Removing the RPM will remove the below dependencies as well.

9. Open a second SSH session to follow the install log for ScaleArc.

   # tail -f /var/log/scalearc-install.log

10. Run the custom installer as shown below.

    # cd /opt/idb/bin/
    # ./custom_install.sh -c Rackspace

    The custom installer will fail while performing a precheck if an RPM of a higher version is found than what ScaleArc supports.

    Below is an example of a failure message.

    

    
    

11. From "/var/log/scalearc-install.log" determine the failed RPM.
