centos7系统GitLab服务器搭建（最新稳定版）

1、GitLab先容

GitLab 是一个用于堆栈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, 重要针对软件开发过程中产生的代
码和文档进行管理，Gitlab 重要针对 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 中大概包含多个 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

假如某些步骤已经操作过了，则无需实行。
2.1 安装SSH依赖

1. yum install -y curl policycoreutils-python openssh-server

复制代码

　　
2.2 启动SSH服务

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

复制代码

1. # 查看启动状态
2. [root@VM-8-8-centos lighthouse]# systemctl status sshd
3. ● sshd.service - OpenSSH server daemon
4.    Loaded: loaded (/usr/lib/systemd/system/sshd.service; enabled; vendor preset: enabled)
5.    Active: active (running) since Fri 2024-05-24 11:35:45 CST; 2h 36min ago
6.      Docs: man:sshd(8)
7.            man:sshd_config(5)
8. Main PID: 1636 (sshd)
9.    CGroup: /system.slice/sshd.service
10.            └─1636 /usr/sbin/sshd -D

复制代码

2.3 设置防火墙-启用IP转发功能（可直接关闭防火墙）

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

复制代码

2.4 安装并启动防火墙

1. yum install firewalld systemd -y
2. systemctl enable firewalld
3. systemctl start firewalld
4. systemctl status firewalld

复制代码

1. #查看启动情况
2. [root@VM-8-8-centos lighthouse]# systemctl status firewalld
3. ● firewalld.service - firewalld - dynamic firewall daemon
4.    Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
5.    Active: active (running) since Fri 2024-05-24 14:20:56 CST; 35s ago
6.      Docs: man:firewalld(1)
7. Main PID: 29060 (firewalld)
8.    CGroup: /system.slice/firewalld.service
9.            └─29060 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid

复制代码

2.5 添加HTTP服务到firewalld

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

复制代码

其中，pemmanent 表示永世见效，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

1. yum install postfix
2. systemctl enable postfix
3. systemctl start postfix
4. systemctl status postfix

复制代码

1. # 查看启动情况
2. [root@VM-8-8-centos lighthouse]# systemctl status postfix
3. ● postfix.service - Postfix Mail Transport Agent
4.    Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)
5.    Active: active (running) since Fri 2024-05-24 11:35:45 CST; 2h 50min ago
6. Main PID: 1360 (master)
7.    CGroup: /system.slice/postfix.service
8.            ├─1360 /usr/libexec/postfix/master -w
9.            ├─1378 qmgr -l -t unix -u
10.            └─9367 pickup -l -t unix -u

复制代码

1. vim /etc/postfix/main.cf
2. # 修改inet_protocols = all为
3. inet_protocols = ipv4
4. #重启服务
5. systemctl restart postfix

复制代码

2.7 添加gitlab镜像

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

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

复制代码

1. # 重新生成缓存
2. yum makecache

复制代码

2.8 安装GitLab

1. yum install -y gitlab-ce #最新稳定版<br><br>yum list gitlab-ce --showduplicates #查看yum源可安装的版本

复制代码

1. yum install -y gitlab-ce-版本号

复制代码

安装信息：

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

54. Thank you for installing GitLab!
55. GitLab was unable to detect a valid hostname for your instance.
56. Please configure a URL for your GitLab instance by setting `external_url`
57. configuration in /etc/gitlab/gitlab.rb file.
58. Then, you can start your GitLab instance by running the following command:
59.   sudo gitlab-ctl reconfigure
61. For a comprehensive list of configuration options please see the Omnibus GitLab readme
62. https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md
64. Help us improve the installation experience, let us know how we did with a 1 minute survey:
65. https://gitlab.fra1.qualtrics.com/jfe/form/SV_6kVqZANThUQ1bZb?installation=omnibus&release=17-0

2.9 修改gitlab设置文件

1. vim  /etc/gitlab/gitlab.rb
2. # 指定服务器ip和自定义端口
3. external_url 'http://192.168.164.195:8000'<br># 修改alertmanager 监听地址防止alertmanager组件无法启动<br><br>alertmanager['listen_address'] = '0.0.0.0:9093'

复制代码

1. [/code][code]# 将8000端口添加到防火墙中
2. firewall-cmd --zone=public --add-port=8000/tcp --permanent

复制代码

1. # 重启防火墙
2. systemctl reload firewalld

复制代码

2.10 重置gitlab

1. gitlab-ctl reconfigure

复制代码

1. # 出现下面信息代表充值成功
2. Notes:
3. Default admin account has been configured with following details:
4. Username: root
5. Password: You didn't opt-in to print initial root password to STDOUT.
6. Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.
8. 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.
10. [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.
11. gitlab Reconfigured!

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：

1. [root@VM-8-8-centos yum.repos.d]# cat /etc/gitlab/initial_root_password
2. # WARNING: This value is valid only in the following conditions
3. #          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).
4. #          2. Password hasn't been changed manually, either via UI or via command line.
5. #
6. #          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.
8. Password: PECffl07TzWOvpTiwZ/Yf8QI7IdTLqHnEbDhvyBBQAE=
10. # NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
