High availability setup

note

Before you proceed, make sure that you have prepared for installation and executed the precheck.

Remember to run the following commands from the directory, where you have downloaded and extracted the installation package, for example, /opt/workfusion/wf_installer.

cd PACKAGE_DIR # /opt/workfusion/wf_installer

Install HAProxy

On each APP server, as a Linux installation user, run the following commands:

$ ./install.sh preinstall lb -c local --limit host-ct1.example.com
$ ./install.sh install lb -c local --limit host-ct1.example.com

note

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.

Install INT components

warning

If you can't complete installation of all servers in one pass, make sure to stop metricbeat on the INT servers, so it doesn't spawn infinite requests to Secret Vault while waiting for the next call to proceed with the setup.

To stop metricbeat, run the command:

wfmanager stop metricbeat

To install the INT components:

1. On the INT2 server, run the following commands as a Linux installation user:

   $ ./install.sh preinstall int2 -c local --limit int2.example.com
   $ ./install.sh install int2 -c local --limit int2.example.com
   

2. On the INT1 server, run the following commands as a Linux installation user:

   $ ./install.sh preinstall int -c local --limit int1.example.com
   $ ./install.sh install int -c local --limit int1.example.com
   $ ./install.sh check int -c local --limit int1.example.com
   

3. Repeat step 2 on all other INT servers, including INT2. Remember to change the INT host correspondingly, for example, int2.example.com for INT2, int3.example.com for INT3.

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.

Install BEP Master components

To install the BEP Master components, on each BEP Master server, run the following commands as a Linux installation user:

$ ./install.sh preinstall bep-master -c local --limit bep-master1.example.com
$ ./install.sh install bep-master -c local --limit bep-master1.example.com
$ ./install.sh check bep-master -c local --limit bep-master1.example.com

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.

Install BEP Agent components

To install the BEP Agent components, on each BEP Agent server, run the following commands as a Linux installation user:

$ ./install.sh preinstall bep-agent -c local --limit bep-agent1.example.com
$ ./install.sh install bep-agent -c local --limit bep-agent1.example.com
$ ./install.sh check bep-agent -c local --limit bep-agent1.example.com

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.

Install APP components

To install the APP components, on each APP server, run the following commands as a Linux installation user:

$ ./install.sh preinstall app -c local --limit host-ct1.example.com
$ ./install.sh install app -c local --limit host-ct1.example.com
$ ./install.sh check app -c local --limit host-ct1.example.com

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.

Install OCR components

If you install Linux OCR, you don't need to install Windows OCR. Otherwise, skip this step and follow the guide.

To install the OCR Linux components, on each OCR server, run the following commands as a Linux installation user:

$ ./install.sh preinstall ocr -c local --limit ocr1.example.com
$ ./install.sh install ocr -c local --limit ocr1.example.com
$ ./install.sh check ocr -c local --limit ocr1.example.com

Remember to change the --limit parameter accordingly for each server. It must reflect the hostname of the server on which you are executing the command.
