HAA Active-Active installation/Set up with CRDB

Active-Active UiPath installation HAA CRDB set-up

Note: If you already have HAA installed, please use the below command to remove/uninstall it from all HAA servers before proceeding to install -

yum remove redislabs -y

Prerequisite:
Ensure that DNS Entries are created for the HAA nodes and Cluster

1. HAA Master Node installation on Primary Datacenter

 

1.      Create the directory where HAA is to be downloaded and extracted, for example: mkdir haa.

2.      Change to the newly created directory using the command: cd /<path-to>/haa/.

3.      Download the installation script by running wget http://download.uipath.com/haa/get-haa.sh.

4.      Make the script executable by running chmod +x get-haa.sh.

5.       Install the master node with the following command: sh get-haa.sh -u <email> -p <password> -d <DNS delegation PRIMARY cluster name>

 

2. HAA Secondary Nodes Installation on Primary Datacenter

After you have installed the master node, on both additional secondary nodes:

  1. Create the directory where HAA is to be downloaded and extracted, for example: mkdir haa.
  2. Change to the newly created directory using the command: cd /<path-to>/haa/.
  3. Download the installation script by running wget http://download.uipath.com/haa/get-haa.sh.
  4. Make the script executable by running chmod +x get-haa.sh.
  5. Install the node with the following command: sh get-haa.sh -u <email> -p <password> -j <IP_address_of_the_master_node in Primary datacenter> -d < DNS delegation PRIMARY cluster name >

3. HAA Cluster Primary Datacenter - Database deletion

Open the HAA User Interface by opening a browser and navigating to the URL – https:// < DNS delegation PRIMARY cluster name >:8443 OR https://<IP address of the master node in Primary datacenter>:8443. Login to the HAA application

Ensure that all 3 nodes are active(status – green)

 

 Click on ‘databases’

The default database – ‘uipath-orchestrator’ should be displayed. Click on the name ‘uipath-orchestrator’ to open the details page

Click on ‘Configuration’ and scroll to the end of the page

On scrolling down, you should see the ‘Delete’ option. Click ‘Delete’ and delete the ‘uipath-orchestrator’ on the HAA cluster in the Primary datacenter.

 

4. HAA Master Node installation on DR/Secondary Datacenter

 

1.      Create the directory where HAA is to be downloaded and extracted, for example: mkdir haa.

2.      Change to the newly created directory using the command: cd /<path-to>/haa/.

3.      Download the installation script by running wget http://download.uipath.com/haa/get-haa.sh.

4.      Make the script executable by running chmod +x get-haa.sh.

5.       Install the master node with the following command: sh get-haa.sh -u <email> -p <password> -d <DNS delegation DR/SECONDARY cluster name>

 

5. HAA Secondary Nodes Installation on DR/Secondary Datacenter

After you have installed the master node, on both additional secondary nodes:

1.      Create the directory where HAA is to be downloaded and extracted, for example: mkdir haa.

2.      Change to the newly created directory using the command: cd /<path-to>/haa/.

3.      Download the installation script by running wget http://download.uipath.com/haa/get-haa.sh.

4.      Make the script executable by running chmod +x get-haa.sh.

5.       Install the node with the following command: sh get-haa.sh -u <email> -p <password> -j <IP_address_of_the_master_node in DR/Secondary datacenter> -d < DNS delegation DR/SECONDARY cluster name >

 

 

6.   HAA Cluster DR/SECONDARY Datacenter - Database deletion

Open the HAA User Interface by opening a browser and navigating to the URL – https://< DNS delegation DR/SECONDARY cluster name >:8443 OR  https://<IP address of the master node in Secondary datacenter>:8443 . Login to the HAA application

Ensure that all 3 nodes are active (status – green)

 

Click on ‘databases’

The default database – ‘uipath-orchestrator’ should be displayed. Click on the name ‘uipath-orchestrator’ to open the details page

Click on ‘Configuration’ and scroll to the end of the page

On scrolling down, you should see the ‘Delete’ option. Click ‘Delete’ and delete the ‘uipath-orchestrator’ on the HAA cluster in the Primary datacenter.

 

 

7. Create Geo-Distributed Database on HAA in PRIMARY Datacenter

On the HAA Application on Primary datacenter, Click on ‘Databases’
