Solution Prerequisites

Installation Steps

The 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.

{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "50m",
        "max-file": "3"
    }
}

Installing Application

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.
To execute the script, give it the execute permissions and execute it.
# chmod +x deploy-wallboard.sh
# ./deploy-wallboard.sh
Create two databases in your DB server corresponding to the 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.

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

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
`DB_USER`	database user
`DB_PASSWORD`	database password
`DB_DRIVER`	JDBC driver e.g., net.sourceforge.jtds.jdbc.Driver
`DB_DIALECT`	Database dialect e.g., org.hibernate.dialect.SQLServer2008Dialect

umm-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`	UMM 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

`FINESSE_USER`	Finesse administrator user
`FINESSE_PASS`	Finesse administrator password
`ADMIN_PASS`	The password of the admin user

synchronizer-variables.env

Name	Description
`CC_TYPE`	Decides whether Cisco contact center is UCCX or UCCE Holds string "UCCX" for UCCX and "UCCE" for UCCE. Default is UCCX
`REDUNDANT_DEPLOYMENT`	Decides if synchronizer deployment is redundant. Set it to "true". Holds strings "true" or "false". Default is false
`INSTANCE_NAME`	Used for differentiation of instances when deployed redundant, could be any string. It should be different on both machines.
`SYNC_AGENTS`	To enable Agent sync set it to "true", default is true
`SYNC_AGENTS_STATS`	Enables/disables agents stats sync, default is true
`SYNC_AGENTS_EMAIL_STATS`	Enables/disables agent email stats, default is false
`SYNC_QUEUES_STATS`	Enables/disables queue stats, default is true
`SYNC_QUEUES`	Enables/disables queues/skillgroups in case of UCCE, default is true
Following variables are used when CC_TYPE = "UCCX"
`UCCX_PUB_IP`	Primary UCCX IP
`UCCX_PUB_USERNAME`	Primary UCCX admin username
`UCCX_PUB_PASSWORD`	Primary UCCX admin password
`UCCX_SUB_USERNAME`	Secondary UCCX admin username
`UCCX_SUB_PASSWORD`	Secondary UCCX admin password
`UCCX_PUB_DB_PASSWORD`	Primary UCCX database reporting user (hruser) password
`UCCX_SUB_DB_PASSWORD`	Secondary UCCX database reporting user (hruser) password
`UCCX_REAL_TIME_PORT`	UCCX real-time APIs port, default is 9080
`SYNC_SKILLS`	Enables/disables UCCX skills sync, default is false

`CCE_DB_USER`	CCE database user
`CCE_DB_PASSWORD`	CCE database password

The following configuration must be done at UCCX. This will allow the UCCX System to write real-time data to tables that Synchronizer uses to fetch for gadgets. This step is not needed for UCCE deployments.
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 the "Wallboard System".
5. Click on the update button.
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.
Update the translation files inside /root/wallboard/docker/translations folder for multilingual UI. The file names in the translation folder should remain unchanged.
Having environment configurations done, copy the wallboard directory on the second machine in/root directory using the following command. (Only for HA deployment)
```
# scp -r /root/wallboard root@<machine-ip>:/root/
```
Having copied the wallboard directory to the second machine, got to /root/wallboard/docker/environment-variables and update the 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. (Only for HA deployment)
Execute the following commands inside /root/wallboard directory on both machines (if in HA, otherwise on the only machine in the cluster).
# chmod 755 install.sh
# ./install.sh
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

Virtual IP configuration (Only for HA deployment)

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

Download keepalived.sh script and place it in /root directory.
Give execute permission and execute the script:
# chmod +x keepalived.sh
# ./keepalived.sh

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 a list of IPs of all the other machines in the cluster. The format of the list is as below: `"#PYTHON2BASH:['192.168.1.76','192.168.1.80']"`
`KEEPALIVED_VIRTUAL_IPS`	Virtual IP of the cluster. It should be available in the LAN. For example: 192.168.1.245
`KEEPALIVED_PRIORITY`	The priority of the node. Instances with lower numbers 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 http://localhost/umm/base/index.html`

Give the execute permission and execute the script:
# chmod +x keep-command.sh
# ./keep-command.sh

Adding License

Browse to https://FQDN/umm in your browser (FQDN will be the domain name assigned to the IP/VIP).
Click on the red warning icon on right, paste the license in the field and click save.
Go to https://FQDN to access wallboard front-end. (FQDN will be the domain name assigned to the VIP).
Go to Data Service on the 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.

# docker-compose -f /root/wallboard/docker/docker-compose.yml down
# docker rm -f keep-alived
# docker system prune
# docker network prune

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
