Deployment Guide

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.

Allow ports in the firewall

For internal communication of the docker swarm, you'll need to allow communication (both inbound and outbound) on the ports: 8083/tcp,8084/tcp , 8085/tcp, 8086/tcp, 8087/tcp, 8844/tcp, 8834/tcp, 8443/tcp and 443/tcp.

To start the firewall on CentOS (if it isn't started already), execute the following commands. You'll have to execute these commands on all the cluster machines.: 

systemctl enable firewalld
systemctl start firewalld

To allow the ports on CentOS firewall, you can execute the following commands. You'll have to execute these commands on all the cluster machines.

firewall-cmd --add-port=8083/tcp --permanent
firewall-cmd --add-port=8084/tcp --permanent
firewall-cmd --add-port=8085/tcp --permanent
firewall-cmd --add-port=8086/tcp --permanent
firewall-cmd --add-port=8087/tcp --permanent
firewall-cmd --add-port=8844/tcp --permanent
firewall-cmd --add-port=8834/tcp --permanent
firewall-cmd --add-port=8443/tcp --permanent
firewall-cmd --add-port=443/tcp --permanent
firewall-cmd --reload

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"
  }
}

Creating Databases

Create a database for UMM and Supervisor Tools services in the MSSQL server with suitable names and follow the application installation steps.

Installing Application

1. Download the deployment script . This script will:

   1. delete the supervisor-tools-deployment directory in the present working directory if it exists.

   2. clone the supervisor-tools-deployment repository from GitLab in the present working directory.

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

   chmod +x supervisor-tools-deployment.sh
   ./supervisor-tools-deployment.sh

3. For UCCE customers only, execute the following command

    rm /root/supervisor-tools-deployment/docker/config/umm/permissions/tam.json

4. For UCCX customers only, uncomment the lines 67 - 77 from file /root/supervisor-tools-deployment/docker/docker-compose.yml

   It should looks like

   tam:
   image: gitlab.expertflow.com:9242/supervisor-tools/team-administration:13.2.1
   ports:
   - "8082:8080"
   env_file:
   - ${PWD}/docker/environment-variables/environment-variables.env
   restart: always
   volumes:
   - ${PWD}/docker/trustStore:/usr/local/trustStore
   networks:
   - st

5. Update environment variables  in the following files inside /supervisor-tools-deployment/docker/environment_variables folder.

   1. Update UMM environment variables in the umm-environment-variables.env file.

   2. Update Supervisor Tools Environment variables in the environment-variables.env. See also, Caller Lists Environment Variables to specify variables of the Caller Lists microservice.

6. Get domain/CA signed SSL certificates for SupervisorTools FQDN/CN and place the files in /root/supervisor-tools-deployment/docker/certificates folder. The file names should be server.crt and server.key.

7. Copy the supervisor-tools-deployment directory to the second machine for HA. Execute below command 

   scp -r supervisor-tools-deployment root@machine-ip:~/

8. Go to the second machine and update the environment variables where necessary.

9. Execute the following commands inside /root/supervisor-tools-deployment directory on both machines.

   chmod 755 install.sh
   ./install.sh

10. 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

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

1. Download keepalived.sh script and place it in /root the 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	Pear machine IP. 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	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. It could be either umm or any backend microservice API. pidof dockerd && wget -O index.html http://localhost:7575/

4.  Update the SERVER_URL in /supervisor-tools-deployment/docker/environment_variables to hold Virtual IP for front-end.

5. Give the execute permission and execute the script on both machine.

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

SMBv2 Commands:

1. Detect if SMB1 enabled
   Get-SmbServerConfiguration | Select EnableSMB1Protocol

   Set-SmbServerConfiguration -EnableSMB1Protocol $true

3. Disable SMB1
   Set-SmbServerConfiguration -EnableSMB1Protocol $false

4. Detect if SMB2 enabled
   Get-SmbServerConfiguration | Select EnableSMB2Protocol

5. Enable SMB2

6. Disable SMB2
   Set-SmbServerConfiguration -EnableSMB2Protocol $false
