CentOS 7.6 Installation Deployment Gitlab

1. Introduction to gitlab

GitLab is an open source project for a warehouse management system. It uses Git as a code management tool and builds a web service on this basis. GitLab is developed by Ukrainian programmers Dmitriy Zaporozhets and Valery Sizov, and it is written in Ruby language. Later, part of the code was rewritten in Go language and is now widely used by large and medium-sized Internet companies at home and abroad.
The differences between git, gitlab, and GitHub are as follows:
git is a command-based version control system with full command operation and no visual interface.
Gitlab is an online code warehouse software based on git. It provides a web visual management interface and is usually used for collaborative development within an enterprise team.
github is an online code hosting warehouse based on git. It also provides a visual management interface. It also provides free accounts and paid accounts, as well as open and private warehouses. Most open source projects choose github as the code hosting warehouse.
