Environment preparation
This article uses Ubuntu 18.04. If you are using other distributions, please ensure that the following preparations have been completed:
-
A server with a Linux system installed.
Make sure the server's network is connected and you can access the external network.
Make sure you have installed the necessary dependent libraries: openssh-server, ca-certificates, curl, postfix. You can use the following command to install dependent libraries:
sudo apt-get install -y openssh-server ca-certificates curl postfix
Install GitLab
-
Add GitLab Community Edition software source:
curl https://packages.gitlab.com/gpg.key 2>&1 | sudo apt-key add - sudo curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
-
Install GitLab:
sudo apt-get install gitlab-ce
The installation process may take some time. After the installation is successful, you can enter the following command in the terminal to start GitLab:
sudo gitlab-ctl reconfigure
-
Access GitLab in the browser:
By default, the port GitLab listens to is 80, so you can enter the address of your server plus port 80 in the browser to access the GitLab page . When using cloud hosts such as Alibaba Cloud, you must first open port 80 on the cloud platform.
http://<server IP>:80/
You will see the welcome page of GitLab, as well as some information about GitLab.
Configuring GitLab
You can configure GitLab through the following steps:
-
Register an administrator account:
On the GitLab welcome page, click "Register a new GitLab administrator account", fill in your administrator information, and then click "Create account" to register an administrator account.
-
Change administrator password:
After registration is completed, click the administrator avatar in the upper right corner, then select "Settings" and select "Account" on the left "Password" to change the administrator password.
-
Create a project:
Click the " " icon in the upper right corner, select "New project", fill in the name and description of the project, and then click "Create project" ” to create a project.
-
Manage projects:
You can manage the project on the project page, including adding members, managing branches, and viewing submission history. You can set access permissions when setting up project permissions to ensure the security of your project.

The timing and reasons for using Linux maintenance mode: 1) When the system starts up, 2) When performing major system updates or upgrades, 3) When performing file system maintenance. Maintenance mode provides a safe and controlled environment, ensuring operational safety and efficiency, reducing impact on users, and enhancing system security.

Indispensable commands in Linux include: 1.ls: list directory contents; 2.cd: change working directory; 3.mkdir: create a new directory; 4.rm: delete file or directory; 5.cp: copy file or directory; 6.mv: move or rename file or directory. These commands help users manage files and systems efficiently by interacting with the kernel.

In Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Linux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.

The steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.
