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

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

Support Browsers and Versions

The following browsers are supported:

  • Chrome: 117+
  • Edge: 117+
  • Firefox: 71+

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.

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:

Email Sender

Email notifications are sent to a project configured recipients . See Create a new project after this installation. For those notifications to be sent, the following will be configured in the settings.

The following information will then be needed:

  • Host URL (like smpt.gmail.com for instance)
  • Authorization method (SMTP, SMTPS, etc.)
  • Sender email address (localyzer@customerdomain.com for instance)
  • Sender password

Docker Install

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.

The supported versions of Linux are:

Other versions of Linux may work correctly, but these are the versions and processes that have been verified.

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 when Command Center is installed. 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

sudo user

A user, such as centos or ec2-user, with sudo privileges is required as the user under which to install Command Center.

  • Note: This should not be the legacy jenkins user.

Create the database conf file

Use the sudo user home for Docker, such as /home/centos for CentOS systems and /home/ec2-user for RedHat virtual systems.

The mysql and conf.d folders may need to be created as well. 

vi /home/<user>/mysql/conf.d/mysql.cnf

[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4

Configuration

Get the installation and update scripts and the install.conf file from the main branch of this public repository:

You should have files such as: 

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

If you need to install SSO version, the relevant files are: 

   install.conf
   BackupCommandCenterDatabase.sh
   InstallSSOCommandCenter.sh
   UninstallCommandCenter.sh
   UpdateSSOCommandCenter.sh
   saml_configuration.conf

Copy the above files under your home directory, for instance <user>/commandCenterInstall where <user> may be /home/centos or /home/ec2-user.

Set up install.conf

Unless directed otherwise, change the top part of the install.conf file.

Set up saml_configuration.conf if you are going to use SAML

The initial version number will be provided for the first installation.

For updates, command_center_image_version will be the only parameter to change in the install.conf file. 

# Provide the Command Center version
# For *Regular* Updates, this should be the only parameter to change
command_center_image_version=113

Make sure to keep a copy of that file in case you overwrite it when updating from the https://github.com/Lingoport/CommandCenterConfig Git repository

#
# After Install, Updates should not need to change anything below
# ----------------------------------------------------------------

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

# Provide the home directory, lingoport/commandcenter/Lingoport_Data
# folder will be created
home_directory=/home/centos

# Provide the Command Center server port
serverPort=8083

Run InstallCommandCenter.sh

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

If you are using sso version installer, run 

    chmod +x *.sh
    sudo ./InstallSSOCommandCenter.sh

To check the running container status 

   sudo docker ps

Re-install Command Center

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

  • Uninstall Command Center
  sudo ./UninstallCommandCenter.sh
  • Verify that Command Center and the database is no longer in the list
  sudo docker ps
  • Remove the image to download and install again
  sudo docker image ls
  sudo docker image rm --force <command center image ID>
  • Start the install again
  sudo ./InstallCommandCenter.sh


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.

Note: Database backup

To backup the database, run the following script: 

    chmod +x *.sh
    sudo ./BackupCommandCenterDatabase.sh

The database backup sql file will be under $home_directory/commandcenter/backup folder, named commandcenter_backup_$current_date.sql

Right after installation, the backup is not necessary. However, as you configure and on-board projects, you may want to set up a backup strategy. To backup the database periodically, schedule to run BackupCommandCenterDatabase.sh on a regular basis, for instance with a Cron service.

Verify Installation

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

   https://commandcenter.mycompany.io/command-center


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.

If the installation is unsuccessful for any reason, do not try to re-install. Instead, uninstall, make any needed changes, and re-install to avoid conflicts. 

sudo ./UninstallCommandCenter.sh

Command Center Update

Get latest scripts

Make sure to make a copy of the install.conf file used previously in case it's overwritten by the git pull / git clone below.

Make sure to update the installation and update scripts and the install.conf file from the main branch of this public repository:

Note: You may need to chmod -x the scripts under DockerScripts before git pull.

Backup the database

You don't have to backup the current version of the database before proceeding to the update to the new version of the system, because the Update script will backup your current database automatically before updating. If you want to do the backup manually, you can use the BackupCommandCenterDatabase.sh script 

    chmod +x *.sh
    sudo ./BackupCommandCenterDatabase.sh

The database backup sql file will be under $home_directory/commandcenter/backup folder, named commandcenter_backup_$current_date.sql

To backup the database periodically, schedule to run BackupCommandCenterDatabase.sh, for instance with cron services.

Note: Restoring the database

If later, at some point, the database needs to be restored, the following shows how to do so: 

    chmod +x *.sh
    sudo ./RestoreCommandCenterDatabase.sh YYYY-MM-DD

Check your database backup sql file under $home_directory/commandcenter/backup folder, they are named commandcenter_backup_$current_date.sql, for example, if you backup the database on 2023 September 20th, you will see a commandcenter_backup_2023-09-20.sql file, and you can use below command to restore it 

    sudo ./RestoreCommandCenterDatabase.sh 2023-09-20

Return to the previous version

1. Stop the current active Command Center container

You can use "docker ps" to see all active containers, and use "docker stop CONTAINER ID" to stop your current Command Center container

2. Restart your previous Command Center server version

You can use "docker ps -a" to see all exited containers, and use "docker start CONTAINER ID" to restart your previous version Command Center container

3. Restore the database to match your previous Command Center server version 

    sudo ./RestoreCommandCenterDatabase.sh YYYY-MM-DD

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

If you are using SSO version installer, run UpdateSSOCommandCenter.sh instead of UpdateCommandCenter.sh

To check the running container status 

   sudo docker ps

The database backup sql file is in $home_directory/commandcenter/ folder, named commandcenter_backup_$current_date.sql

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:8.0                     "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


How to backup and restore a system

If you have a system that you want to install a new version of Command Center, but keep the current configuration, here are the steps to do that.

  • Backup the Command Center databases
  sudo ./BackupCommandCenterDatabase.sh

This will create two files <home>/commandcenter/backup/commandcenter_backup_YYYY-MM-DD.sql and <home>/commandcenter/backup/LRM_backup_YYYY-MM-DD.sql Where YYYY-MM-DD is the current date.

  • Stop the currently running Command Center container and its associated MySQL container
  sudo docker ps
  sudo docker stop <Command Center Container ID> <MySQL Container ID>
  sudo docker ps
  • Modify the install.conf file for the correct version of Command Center to install
  • Install Command Center
  sudo ./InstallCommandCenter.sh

If there is an error about the container in use, remove the container that is identified and attempt the install again. 

  sudo docker rm <container>
  sudo ./InstallCommandCenter.sh
  • Verify that Command Center comes up in the browser. Login with the CCAdmin user. There should be no projects or configuration set up
  • Restore from the database
  sudo ./RestoreCommandCenterDatabase.sh YYYY-MM-DD
  • Verify that Command Center is populated with the correct information

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.
