Pre-Requisites

Before installing or updating Command Center, please verify this section is complete.

Intro

IT

When installing Command Center on premises, the customer IT group is very important to the successful deployment of the Lingoport applications when installing the suite on site. In particular, the IT group that sets up the Linux system must understand the usage model for the system. Lingoport requires a meeting with the parties responsible for setting up and maintaining the host system before installation can properly begin. The hope is that once the system is setup for installation, minimal IT interaction is necessary.


Preparations must be made with the IT team to ensure that all prerequisites are met before installation. For new installations, this is the recommended method to use to verify that all the various actors work together well.

Basics

Before installing Command Center, the following needs to be configured:

  • Hardware
  • Linux
  • Docker
  • Firewall
  • Https

Hardware & Software Requirements

The following sections describe the hardware and software requirements for Command Center.

Please note that the Globalyzer Server installation is in a different section.

Hardware Requirements

Element Minimum Recommended
CPU 2 4
Memory 16 GB 16 GB
Disk 160 GB 500 GB

The Globalyzer Server may be hosted by Lingoport, reside on another server, or be installed on the same system. Other Linux and Windows machines may have Globalyzer clients installed.

Software requirements

The current versions of these software products can be found at: Current versions of Lingoport products and supporting applications

Software Recommended
Operating System Linux, CentOS (7) or RedHat (8)

Since this is a Docker installation, most of the containers will be managed by Docker. However, volumes will be mounted on the Linux VM and a database configuration file will reside on the VM: This requires Linux.

Access and Ports / Firewall

Command Center may need to be accessible by Lingoport and customer personnel to configure jobs, check the console if any problem arise, run jobs if necessary. Command Center needs to be accessible by many customer actors, including development teams, management, and QA, Lingoport, Translation Vendors.

Please see External Access and Ports for all the details.

HTTPS

HTTPS is recommended but not necessary for the Command Center installation. HTTPS may already be set up or your IT may have a standard on how to set up HTTPS. If that's the case, go the next section.

Otherwise, follow this link for a suggested HTTPS configuration:

Docker Pre-Requisite

Docker is a platform that allows you to easily develop, test, and deploy applications as containers. This section will walk you through the process of installing Docker on a Linux system.

On the system (most likely a VM) dedicated to Command Center, make sure you have the latest version of docker up and running. The following steps may help.

A user with sudo privileges is required to run most commands.

Uninstall old docker versions

This is an optional step in case your docker version is out of date: 

   sudo yum remove docker \
                 docker-client \
                 docker-client-latest \
                 docker-common \
                 docker-latest \
                 docker-latest-logrotate \
                 docker-logrotate \
                 docker-engine

Install docker using the repository

   sudo yum install -y yum-utils
   sudo yum-config-manager \
     --add-repo \
     https://download.docker.com/linux/centos/docker-ce.repo

   sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Start Docker.

Start docker using the following command: 

   $ sudo systemctl start docker

Enable the Docker service to start automatically on system boot by running the following command: 

   $ sudo systemctl enable docker

Verify that Docker Engine is installed correctly

Run the hello-world image. 

   $ sudo docker run hello-world

This command will run a test container and display a message indicating that the installation is working properly.

Credentials

When deploying Command Center, the configuration determines if the user management is done by Command Center itself, via an LDAP, or via SSO (using SAML).

Command Center User Database

One administration user is configured. Contact support (at) lingoport (dot) com in order to get an administration user and password. That user can then create Command Center users. It is strongly recommended to change the first administration password and keep it safe.

LDAP

  • LDAP Connection
  • Management

SSO

  • SSO Connection
  • Management


New Command Center Installation

Create the database conf file

If you are using a CentOS system:

Uses the centos user, with sudo privileges, as default user for docker

  • /home/centos/mysql/conf.d/mysql.cnf
   [client]
   default-character-set = utf8mb4
   [mysql]
   default-character-set = utf8mb4

If you are using a RedHat system:

  • /home/ec2-user/mysql/conf.d/mysql.cnf
   [client]
   default-character-set = utf8mb4
   [mysql]
   default-character-set = utf8mb4

Configuration

Request the CommandCenterInstall.zip file from your customer success engineer. The zip file contains four files: 


   install.conf
   InstallCommandCenter.sh
   UninstallCommandCenter.sh
   UpdateCommandCenter.sh

Copy the above files under your home directory,for instance /home/centos/commandcenterinstall or /home/ec2-user/commandcenterinstall.

Set up install.conf

Fill in your home directory, DB password, serverURL and port number, your Docker Hub username and token. The initial version number will be provided for the first installation. For updates, this will be the only parameter to change in the install.conf file. 

#!/bin/bash
#
# Provide your home directory, lingoport/commandcenter/Lingoport_Data folder will be created
#
home_directory=/home/centos

#
# Provide the MYSQL root password you want to create for the MySQL database container
#
database_root_password=

#
# Provide your Docker Hub username
#
docker_username=

#
# Provide your Docker Hub account token
#
docker_account_token=

#
# The Server URL: '"https://yourserver/command-center"'
#
serverURL=

#
# Provide the Command Center server port
#
serverPort=

#
# Command Center version
#
command_center_image_version=

# DO NOT CHANGE THE PARAMETERS BELOW

#
# Provide the Docker network name you want to create
#
database_network=mysqlnetscommand

#
# The company name on your Localyzer license
#
company_name=


# lingoport/command-center_dev or lingoport/command-center
docker_image=lingoport/command-center

Run InstallCommandCenter.sh

    chmod +x InstallCommandCenter.sh
    sudo ./InstallCommandCenter.sh

To check the running container status 

   sudo docker ps

If you need to re-run the InstallCommandCenter.sh, make sure to run UninstallCommandCenter.sh first to clean your environment.

Note: Docker image version is not the Command Center version, check latest docker image version at https://hub.docker.com/repository/docker/lingoport/command-center_dev/general

You should see at least an MySQL and a Command Center container running.

Verify Installation

Log in to the URL based on the command-center-config.sh settings, so something like: 

   https://commandcenter.mycompany.io/


You should now be able to install the licenses and create projects.

The Command Center will initially have one Administrator user CCAdmin with the password please.reset.me.

Command Center Update

Update install.conf

Change the version number in the install.conf to get the Command Center image update version. 

 command_center_image_version=<new version number>

See full Configuration above.

Run UpdateCommandCenter.sh

    chmod +x UpdateCommandCenter.sh
    sudo ./UpdateCommandCenter.sh

To check the running container status 

   sudo docker ps

Start and Stop System

  • From Command Center, as an administrator, go to settings and click 'Restart'
  • From the VM, use docker commands to stop or start Command Center. For example:
   sudo docker ps
   sudo docker stop <hash>
   sudo docker ps
   
   sudo docker container ls -a | grep command
   sudo docker start <hash>
   sudo docker ps


Uninstall

 sudo ./UninstallCommandCenter.sh
 Uninstalling the Command Center Servers ...

 sudo docker ps
 CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

FAQ and Troubleshooting

Make sure the Server URL is reachable

Navigate to the server URL set up in install.conf: is the login screen available?

If it is not, first check that the docker container is up and running. Make sure both lingoport/command-center and mysql are running. 

 sudo docker container ls -a 
 CONTAINER ID   IMAGE                         COMMAND                  CREATED      STATUS       PORTS                                       NAMES
 3d9da7a80e0a   lingoport/command-center:80   "catalina.sh run"        3 days ago   Up 6 hours   0.0.0.0:8081->8080/tcp, :::8081->8080/tcp   pedantic_aryabhata
 683c55907c06   mysql:5.7                     "docker-entrypoint.s…"   3 days ago   Up 6 hours   3306/tcp, 33060/tcp                         quizzical_newton

Check with IT that the DNS for that system is correct.

Check with IT that the firewall allows for reaching the URL from your system.

Ask IT to check the https and the server URL / DNS.

To check files on disk

To troubleshoot, it may be necessary to check files handled by Docker, such as looking for reports under Lingoport_Data. In that case, first use the Docker PS command to get the container ID of the Command Center application. 

 sudo docker container ls -a 
 CONTAINER ID   IMAGE                         COMMAND                  CREATED      STATUS       PORTS                                       NAMES
 3d9da7a80e0a   lingoport/command-center:80   "catalina.sh run"        3 days ago   Up 6 hours   0.0.0.0:8081->8080/tcp, :::8081->8080/tcp   pedantic_aryabhata

With the container ID, execute the following command to run bash with access to those files: 

 sudo docker exec -it 3d9da7a80e0a bash

Next Steps

Command Center is now ready to be used. Proceed to the URL configured in the installation and follow the User's Guide's steps.
