1. 安装准备

centos8环境安装---用的dnf安装器
下载社区版安装包---gitlab官网下载
安装参考---gitlab官方教程

2. 安装依赖环境

#安装依赖
sudo dnf install -y curl policycoreutils openssh-server

#打开HTTP, HTTPS和SSH访问
sudo systemctl enable sshd
sudo systemctl start sshd
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo systemctl reload firewalld

#安装Postfix,用来发送通知邮件
sudo dnf install postfix
sudo systemctl enable postfix
sudo systemctl start postfix

3. 安装gitlab-ce

在官网下载好安装包后,放到自己习惯放的路径下即可

#找到路径下的文件,在当前目录执行rpm安装命令,一般中间不会出现问题,我之前安装gitlab12.3.5版本有的时候还会出现问题,具体解决办法我写到上个博客系统去了(上个博客系统被我误删了😭 ),所以你们只能去搜一下了
#一般出现gitlab的logo图案就算是安装完毕了
rpm -ivh gitlab-ce-13.9.2-ce.0.el8.x86_64.rpm

4. 配置域名/ip

#编辑gitlab配置文件
vim /etc/gitlab/gitlab.rb
#在里边某行能找到external_url =“***”
#将里边的***修改为自己想要访问的地址即可----ps:记得添加http
#如果http不用80用其他端口访问直接再后边加上其他端口号即可
external_url = "http://192.168.1.5"
external_url = "http://www.***.com"
external_url = "http://www.***.com:9999"
external_url = "http://192.168.1.5:9999"

#如果自己项配置https访问的话,需要自己先去申请ssl证书,我这个版本的gitlab用的是nginx的证书
#需要修改,并且把http修改为https,不用默认的443,用其他端口直接添加即可
#ssl证书路径可随意修改,能读取到文件就好
#有些人配置了强制跳转https,我这里木有配置

external_url = "https://www.***.com"
#external_url = "https://www.***.com:9999"
nginx['ssl_certificate'] = "/etc/gitlab/ssl/***.crt"
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/***.key"

#如果需要强制从http转为https把这个打开即可
nginx['enable'] = true
nginx['redirect_http_to_https'] = true
nginx['redirect_http_to_https_port'] = 80

#配置完毕后记得重新配置gitlab
sudo gitlab-ctl reconfigure
#重启gitlab
sudo gitlab-ctl restart 

#一定记得去开放端口号,阿里云,腾讯云等还需要去开白名单

gitlab常用命令

#启动
gitlab-ctl start
#停止
gitlab-ctl stop
#重启
gitlab-ctl restart

#实时查看日志
gitlab-ctl tail
#实时各个模块日志
gitlab-ctl tail redis/postgresql/gitlab-workhorse/logrotate/nginx/sidekiq/unicorn

#Gitlab服务构成
nginx: 静态web服务器
gitlab-shell: 用于处理Git命令和修改authorized keys列表
gitlab-workhorse: 轻量级的反向代理服务器
logrotate:日志文件管理工具
postgresql:数据库
redis:缓存数据库
sidekiq:用于在后台执行队列任务(异步执行)
unicorn:HTTP服务,GitLab Rails应用是托管在这个服务器上面的。
#主要配置文件目录
主配置文件: /etc/gitlab/gitlab.rb
文档根目录: /opt/gitlab
默认存储库位置: /var/opt/gitlab/git-data/repositories
Nginx配置文件: /var/opt/gitlab/nginx/conf/gitlab-http.conf
Postgresql数据目录: /var/opt/gitlab/postgresql/data

扩展

备份设置

vim /etc/gitlab/gitlab.rb

#指定备份后数据存放的路径、权限、时间配置
gitlab_rails['manage_backup_path'] = true                  #536行      开启备份功能
gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"    #537行      指定备份的路径
gitlab_rails['backup_archive_permissions'] = 0644          #540行      备份包(tar格式压缩包)的权限
gitlab_rails['backup_keep_time'] = 604800                 #545行      备份的保留时间,单位是秒
创建备份目录并授权:
mkdir /var/opt/gitlab/backups && chown -R git.git /var/opt/gitlab/backups/

配置完毕后
gitlab-ctl reconfigure  # 重载配置,使之生效

手动备份

gitlab-rake gitlab:backup:create  # 备份数据

#不知道之前版本怎么样,我这gitlab13.9.2版本在/opt/gitlab/bin/目录下找到了gitlab-backup我就尝试运行了一下,结果正常生成备份,与上边的命令生成的一样

gitlab-backup

定时备份

使用Crontab任务进行定时备份。

[root@VM-8-13-centos ~]# crontab -l
no crontab for root
[root@VM-8-13-centos ~]# 
[root@VM-8-13-centos ~]# crontab -e
no crontab for root - using an empty one
crontab: installing new crontab
[root@VM-8-13-centos ~]# 
[root@VM-8-13-centos ~]# crontab -l
# 编辑内容
0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1
[root@VM-8-13-centos ~]#
#重启crontab 
/bin/systemctl restart crond.service  

还原数据
特别注意:

备份目录和gitlab.rb中定义的备份目录必须一致
GitLab的版本和备份文件中的版本必须一致,否则还原时会报错。

[root@VM-8-13-centos ~]# cat /etc/gitlab/gitlab.rb |grep "backup_path" |grep -Ev "^$"  # 确认备份目录
gitlab_rails['backup_path'] = "/var/opt/gitlab/backups"
[root@VM-8-13-centos ~]# 
[root@VM-8-13-centos ~]# ll /var/opt/gitlab/backups/  # 确认备份文件
