centos7系统GitLab服务器搭建（最新稳定版）

2024-07-02 09:29 由小尼发表于 #后端开发

1、GitLab介绍

GitLab 是一个用于仓库管理系统的开源项目，使 Git 作为代码管理工具，并在此基础上搭建起来的 Web 服务。

Gitlab 是被广泛使用的基于 git 的开源代码管理平台，基于 Ruby on Rails 构建, 主要针对软件开发过程中产生的代

码和文档进行管理，Gitlab 主要针对 group 和 project 两个维度进行代码和文档管理，其中 group 是群组，

project是工程项目，一个 group 可以管理多个 project，可以理解为一个群组中有多项软件开发任务，而一个

project 中可能包含多个 branch，意为每个项目中有多个分支，分支间相互独立，不同分支可以进行归并。

2、GitLab安装

如果某些步骤已经操作过了，则无需执行。

2.1 安装SSH依赖

yum install -y curl policycoreutils-python openssh-server

2.2 启动SSH服务

[root@VM-8-8-centos lighthouse]# systemctl enable sshd
[root@VM-8-8-centos lighthouse]# systemctl start sshd

# 查看启动状态
[root@VM-8-8-centos lighthouse]# systemctl status sshd
● sshd.service - OpenSSH server daemon
   Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled; vendor preset: enabled)
   Active: active (running) since Fri 2024-05-24 11:35:45 CST; 2h 36min ago
     Docs: man:sshd(8)
           man:sshd_config(5)
 Main PID: 1636 (sshd)
   CGroup: /system.slice/sshd.service
           └─1636 /usr/sbin/sshd -D

2.3 设置防火墙-启用IP转发功能（可直接关闭防火墙）

vim /etc/sysctl.conf
# 在文件末尾添加
net.ipv4.ip_forward = 1

2.4 安装并启动防火墙

yum install firewalld systemd -y
systemctl enable firewalld
systemctl start firewalld
systemctl status firewalld

#查看启动情况
[root@VM-8-8-centos lighthouse]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
   Active: active (running) since Fri 2024-05-24 14:20:56 CST; 35s ago
     Docs: man:firewalld(1)
 Main PID: 29060 (firewalld)
   CGroup: /system.slice/firewalld.service
           └─29060 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid

2.5 添加HTTP服务到firewalld

[root@VM-8-8-centos lighthouse]# firewall-cmd --permanent --add-service=http
success
[root@VM-8-8-centos lighthouse]# systemctl reload firewalld

其中，pemmanent 表示永久生效，若不加 --permanent 系统下次启动后就会失效。

2.6 安装Postfix以发送邮件

yum install postfix
systemctl enable postfix
systemctl start postfix
systemctl status postfix

# 查看启动情况
[root@VM-8-8-centos lighthouse]# systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
   Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2024-05-24 11:35:45 CST; 2h 50min ago
 Main PID: 1360 (master)
   CGroup: /system.slice/postfix.service
           ├─1360 /usr/libexec/postfix/master -w
           ├─1378 qmgr -l -t unix -u
           └─9367 pickup -l -t unix -u

vim /etc/postfix/main.cf
# 修改inet_protocols = all为
inet_protocols = ipv4
#重启服务
systemctl restart postfix

2.7 添加gitlab镜像

在 /etc/yum.repos.d 目录下新建 gitlab-ce.repo 文件并保存，内容如下：

[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1

# 重新生成缓存
yum makecache

2.8 安装GitLab

yum install -y gitlab-ce #最新稳定版

yum list gitlab-ce --showduplicates #查看yum源可安装的版本

yum install -y gitlab-ce-版本号

安装信息：

[root@VM-8-8-centos yum.repos.d]# yum install -y gitlab-ce
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

Help us improve the installation experience, let us know how we did with a 1 minute survey:

Complete!

2.9 修改gitlab配置文件

vim  /etc/gitlab/gitlab.rb
# 指定服务器ip和自定义端口
external_url 'http://192.168.164.195:8000'
# 修改alertmanager 监听地址防止alertmanager组件无法启动

alertmanager['listen_address'] = '0.0.0.0:9093'

# 将8000端口添加到防火墙中
firewall-cmd --zone=public --add-port=8000/tcp --permanent

# 重启防火墙
systemctl reload firewalld

2.10 重置gitlab

gitlab-ctl reconfigure

# 出现下面信息代表充值成功
Notes:
Default admin account has been configured with following details:
Username: root
Password: You didn't opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.

NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

[2024-05-24T16:47:38+08:00] WARN: This release of Cinc Client became end of life (EOL) on May 1st 2024. Please update to a supported release to receive new features, bug fixes, and security updates.
gitlab Reconfigured!

2.11 启动gitlab

gitlab-ctl restart

[root@VM-8-8-centos yum.repos.d]# gitlab-ctl restart
ok: run: alertmanager: (pid 11174) 0s
ok: run: gitaly: (pid 11203) 0s
ok: run: gitlab-exporter: (pid 11219) 0s
ok: run: gitlab-kas: (pid 11280) 0s
ok: run: gitlab-workhorse: (pid 11289) 0s
ok: run: logrotate: (pid 11299) 1s
ok: run: nginx: (pid 11306) 0s
ok: run: node-exporter: (pid 11312) 1s

ok: run: redis: (pid 11361) 0s
ok: run: redis-exporter: (pid 11368) 1s
ok: run: sidekiq: (pid 11383) 0s

注意：

alertmanager报错Failed to get final advertise address: No private IP address found, and explicit IP no

修改/etc/gitlab/gitlab.rb

alertmanager['listen_address'] = '0.0.0.0:9093'

2.12 访问Gitlab页面

通过服务器ip和指定端口进行访问：

查看初始化密码：

[root@VM-8-8-centos yum.repos.d]# cat /etc/gitlab/initial_root_password 
# WARNING: This value is valid only in the following conditions
#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

Password: PECffl07TzWOvpTiwZ/Yf8QI7IdTLqHnEbDhvyBBQAE=

# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
