Solution Prerequisites

Internet should be available on the machine where the application is being installed and connections on port 9242 should be allowed in the network firewall to carry out the installation steps.  All the commands start with a # indicating that root user privileges are required to execute these commands. Trailing # is not a part of the command.

Configure Log Rotation

Add the following lines in /etc/docker/daemon.json file (create the file if not there already) and restart the docker daemon using systemctl restart docker. Perform this step on all the machines in the cluster in case of HA deployment.

Installing Application

1. Download the deployment script deploy-wallboard.sh and place it in the /root directory. This script will:
   1. delete the wallboard directory in the present working directory if it exists.
   2. clone the wallboard repository from gitlab in the present working directory.

2. To execute the script, give it the execute permissions and execute it. 

   # chmod +x deploy-wallboard.sh # ./deploy-wallboard.sh

3. Create two databases in your DB server corresponding to wallboard and umm. This step is only required if you're using your own DB server/cluster. If you're using the built in MSSQL database server, you don't need to do anything. 

4. Update environment variables  in the following files inside /root/wallboard/docker/environment_variables folder.

   1. common-variables.env

      Name	Description
      Do not change the default values for non-HA deployment OR if you want to use the built in database. For HA, use SQL server cluster settings instead of the defaults. If you want to use your own MSSQL instance anyway, update the following variables accordingly.
      DB_URL	Wallboard database connection url For example: jdbc:jtds:sqlserver://<MACHINE-IP or FQDN>:PORT/db_name jdbc:jtds:sqlserver://<MACHINE-IP or FQDN>:PORT/db_name;instanceName=SomeInstance

5. The following configuration must be done at UCCX. This will allow UCCX System to write real-time data to tables that Synchronizer uses to fetch for gadgets.
   1. Go to Tools > “Real Time Snapshot Config” on UCCX Administration UI.
   2. Enable all three checkboxes
   3. Select “5” from dropdown against “Data Writing Interval”
   4. Provide the IP addresses of the machine where Synchronizer will run (comma separated IPs in case of HA, otherwise only one IP) separated by commas in the field against “Server Name” under “Wallboard System.
   5. Click on update button. 
6. Get domain/CA signed SSL certificates for wallboard FQDN/CN and place the files in /root/wallboard/docker/certificates folder. The file names should be server.crt and server.key.
7. Update the translation files inside /root/wallboard/docker/translations folder for multilingual UI. The file names in translation folder should remain unchanged.

8. Having environment configurations done, copy the wallboard directory on the second machine in/rootdirectory using the following command. 

   # scp -r /root/wallboard root@<machine-ip>:/root/

9. Having copied the wallboard directory to the second machine, got to /root/wallboard/docker/environment-variables and update INSTANCE_NAME variable in synchronizer-variables.env. Set it to any value other than the value that is set in the first machine. It will differentiate the two VMs as only one synchronizer service will be active. If one goes down, the other starts synchronizing data from UCCE/UCCX.

10. Execute the following commands inside /root/wallboard directory on both machines.

    # chmod 755 install.sh # ./install.sh

11. Run the following command to ensure that all the components are up and running. The screenshot below shows a sample response for a standalone non-HA deployment. 

    # docker ps

    
    
    

12. Run below in script in wallboard database once the containers are up and running 

    ALTER TABLE queue ADD skill_group_id int;
    
    ALTER TABLE queue ADD agent_group_id int;

13. If queue and agent attributes are not loading while creating gadgets, restart  NGINX (docker_proxy_1) container using the following command 

    docker restart container_id

Virtual IP configuration

Repeat the following steps for all the machines in the HA cluster.

1. Download keepalived.sh script and place it in /root directory.

2. Give execute permission and execute the script: 

   # chmod +x keepalived.sh # ./keepalived.sh

3. Configure keep.env file inside /root/keep-alived folder

   Name	Description
   KEEPALIVED_UNICAST_PEERS	IPs of the machines in the cluster. On each machine, this variable should have the IP of the other machine in HA
   KEEPALIVED_VIRTUAL_IPS	Virtual IP of the cluster. It should be available in the LAN. For example: 192.168.1.245
   KEEPALIVED_PRIORITY	Priority of the node. Instance with lower number will have a higher priority. It can take any value from 1-255.
   KEEPALIVED_INTERFACE	Name of the network interface with which your machine is connected to the network. On CentOS, ifconfig or ip addr sh will show all the network interfaces and assigned addresses.
   CLEARANCE_TIMEOUT	Corresponds to the initial startup time of the application in seconds which is being monitored by keepalived. A nominal value of 60-120 is good enough
   KEEPALIVED_ROUTER_ID	Do not change this value.
   SCRIPT_VAR	This script is continuously polled after 2 seconds. Keepalived relinquishes control if this shell script returns a non-zero response. For wallboard, it should be: pidof dockerd && wget -O index.html https://localhost:443

4. Give the execute permission and execute the script: 

   # chmod +x keep-command.sh # ./keep-command.sh

Adding License

1. Browse to https://FQDN/umm in your browser (FQDN will be the domain name assigned to the IP/VIP). 
2. Click on the red warning icon on right, paste the license in the field and click save. 
   
3. Go to https://FQDN to access wallboard front-end. (FQDN will be the domain name assigned to the VIP).
4. Go to Data Service on left side menu to define data services. There will be two data services named Agent Service and Queue Service with the following URLs.

       https://FQDN/agent-service and https://FQDN/queue-service 

            

Uninstalling

To uninstall the application completely, execute the following commands.

Troubleshooting

• To update any changes in the environment variables and/or compose file, simply execute the install script again:

  /root/wallboard/install.sh

• To restart the whole stack completely, execute the following commands: 

  # docker-compose -f /root/wallboard/docker/docker-compose.yml down # /root/wallboard/install.sh
