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
yum install -y curl policycoreutils-python openssh-server
2.2 启动SSH服务
# systemctl enable sshd
# systemctl start sshd# 查看启动状态
# 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 -D2.3 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 = 12.4 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
# 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 --nopid2.5 添加HTTP服务到firewalld
# firewall-cmd --permanent --add-service=http
success
# systemctl reload firewalld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
yum install postfix
systemctl enable postfix
systemctl start postfix
systemctl status postfix# 查看启动情况
# 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 -uvim /etc/postfix/main.cf
# 修改inet_protocols = all为
inet_protocols = ipv4
#重启服务
systemctl restart postfix2.7 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：
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 makecache2.8 安装GitLab
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yum install -y gitlab-ce-版本号安装信息：
# 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:

Installed:
gitlab-ce.x86_64 0:17.0.1-ce.0.el7
Complete!2.9 修改gitlab设置文件
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'<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'# 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 firewalld2.10 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.
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.

查看初始化密码：
# 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.
