下面是官网复制过来的官方安装方法，最简单的安装，在我大天朝，只能望天兴叹，你可翻墙安装或者略过这里，看下面的。
- 安装并配置必要的依赖项
If you install Postfix to send email please select 'Internet Site' during setup. Instead of using Postfix you can also use Sendmail or configure a custom SMTP server and configure it as an SMTP server.
On Centos 6 and 7, the commands below will also open HTTP and SSH access in the system firewall.
sudo yum install curl openssh-server openssh-clients postfix cronie
sudo service postfix start
sudo chkconfig postfix on
sudo lokkit -s http -s ssh
- 添加gitlab服务器包和安装包
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install gitlab-ce
If you are not comfortable installing the repository through a piped script, you can find the entire script here and select and download the package manually and install using gitlab/gitlab-ce
curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/6/gitlab-ce-XXX.rpm/download
curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/7/gitlab-ce-10.2.2-ce.0.el7.x86_64.rpm/download
rpm -i gitlab-ce-XXX.rpm- 配置并启动GitLab
sudo gitlab-ctl reconfigure
- 浏览器打开并登录
On your first visit, you'll be redirected to a password reset screen to provide the password for the initial administrator account. Enter your desired password and you'll be redirected back to the login screen.
The default account's username is root. Provide the password you created earlier and login. After login you can change the username if you wish.

# 找到 external_url 'http://000.00.00.00:8081'

# 将`external_url = 'http://git.example.com'`修改为自己的IP地址：`http://xxx.xx.xxx.xx`，

sudo gitlab-ctl reconfigure
# 清除缓存
sudo gitlab-rake cache:clear RAILS_ENV=productionUsername: root

开启 Configuring Registry 功能，只需修改配置 /etc/gitlab/gitlab.rb 文件，将 registry_external_url 的值修改为 http://192.168.188.211:5008
registry_external_url 'http://192.168.188.211:5008'registry_external_url 这个地址是我们使用 docker 命令进行 pull 或者 push 镜像的仓库地址。
重启 Gitlab 后，可以在 Gitlab 左侧面板看到 Container Registry 的菜单。
按照 gitlab 给出的提示，我们先登录上 gitlab 的 registry：
docker login 192.168.188.211:5008
Username: ****
Password: **注意：personal_access_tokens 而不是真正的密码
docker build -t 192.168.188.211:5008/docker/docker-static-service-template .

使用rails工具打开终端
sudo gitlab-rails console production查询用户的email，用户名，密码等信息，id:1 表示root账号
user = User.where(id: 1).first重新设置密码
user.password = '新密码'
user.password_confirmation = '新密码' 保存密码
user.save!完整的操作ruby脚本
user = User.where(id: 1).first
user.password = '新密码'
user.password_confirmation = '新密码'
user.save!使用Gitlab一键安装包安装Gitlab非常简单, 同样的备份恢复与迁移也非常简单,用一条命令即可创建完整的Gitlab备份:
修改/etc/gitlab/gitlab.rb来修改默认存放备份文件的目录:
gitlab_rails['backup_path'] = '/mnt/backups' gitlab-rake gitlab:backup:create以上命令将在 /var/opt/gitlab/backups 目录下创建一个名称类似为xxxxxxxx_gitlab_backup.tar的压缩包, 这个压缩包就是Gitlab整个的完整部分, 其中开头的xxxxxx是备份创建的时间戳。
修改后使用gitlab-ctl reconfigure命令重载配置文件。
这里放你的备份文件文件夹，和仓库源文件。
/var/opt/gitlab/backups # 备份文件文件夹
/var/opt/gitlab/git-data/repositories # git仓库源文件通过crontab使用备份命令实现自动备份
crontab -e
# 每天2点备份gitlab数据
0 2 * * * /usr/bin/gitlab-rake gitlab:backup:create
0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create上面两行保存之后，重新载入配置
service crond reload
# or
systemctl reload crond.service设置只保存最近7天的备份，编辑 /etc/gitlab/gitlab.rb 配置文件，找到如下代码，删除注释 # 保存
# /etc/gitlab/gitlab.rb 配置文件 修改下面这一行
gitlab_rails['backup_keep_time'] = 604800 重新加载gitlab配置文件
sudo gitlab-ctl reconfigure 迁移如同备份与恢复的步骤一样, 只需要将老服务器 /var/opt/gitlab/backups 目录下的备份文件拷贝到新服务器上的 /var/opt/gitlab/backups 即可(如果你没修改过默认备份目录的话)。 然后执行恢复命令。
如果修改了，首先进入备份 gitlab 的目录，这个目录是配置文件中的 gitlab_rails['backup_path'] ，默认为 /var/opt/gitlab/backups 。
然后停止 unicorn 和 sidekiq ，保证数据库没有新的连接，不会有写数据情况。
# 停止相关数据连接服务
gitlab-ctl stop unicorn
# ok: down: unicorn: 0s, normally up
gitlab-ctl stop sidekiq
# ok: down: sidekiq: 0s, normally up
# 从xxxxx编号备份中恢复
# 然后恢复数据，1406691018为备份文件的时间戳
gitlab-rake gitlab:backup:restore BACKUP=1406691018
# 新版本 1483533591_2017_01_04_gitlab_backup.tar
gitlab-rake gitlab:backup:restore BACKUP=1483533591_2017_01_04_gitlab_backup.tar
# 启动Gitlab
sudo gitlab-ctl start 判断是执行实际操作的gitlab相关用户：git，没有得到足够的权限。依次执行命令：
# 恢复过程中没有权限
mkdir /var/opt/gitlab/backups
chown git /var/opt/gitlab/backups
chmod 700 /var/opt/gitlab/backups
# 恢复成功页面报没有权限的错误
sudo chown -R git:git /var/opt/gitlab/git-data/repositories
sudo chmod -R ug+rwX,o-rwx /var/opt/gitlab/git-data/repositories
sudo chmod -R ug-s /var/opt/gitlab/git-data/repositories
sudo find /var/opt/gitlab/git-data/repositories -type d -print0 | sudo xargs -0 chmod g+s如果备份文件报没有权限，通过ls -al查看权限是不是git，而不是root，通过下面方式给git用户权限
sudo chown -R git:git 1483533591_2017_01_04_gitlab_backup.tar# 登陆gitlab的安装服务查看配置文件
cat /var/opt/gitlab/gitlab-rails/etc/database.yml
vim /var/opt/gitlab/postgresql/data/postgresql.conf
# listen_addresses = '192.168.1.125' # 修改监听地址为ip
# 或者改为 "*"修改 pg_hba.conf 配置
vim /var/opt/gitlab/postgresql/data/pg_hba.conf
# 将下面这一行添加到配置的最后面
# host all all 0.0.0.0/0 trust如果不希望允许所有IP远程访问，则可以将上述配置项中的0.0.0.0设定为特定的IP值。
重启 postgresql 数据库
gitlab-ctl restart postgresql
查看 /etc/passwd 文件里边 gitlab 对应的系统用户
[root@localhost ~]$ cat /etc/passwd
...
gitlab-psql:x:493:490::/var/opt/gitlab/postgresql:/bin/sh # gitlab的postgresql用户# 配置目录
/etc/gitlab/gitlab.rb
# 生成好的nginx配置
/var/opt/gitlab/nginx/conf/gitlab-http.conf
# 备份目录
/var/opt/gitlab/backups直接将nginx配置复制到你自己的nginx配置中，停掉gitlab的nginx
cp /var/opt/gitlab/nginx/conf/gitlab-http.conf /usr/local/nginx/conf/vhost/将你的SSL证书配置复制进去

}暴力升级前先备份，然后停止所有服务运行，记得备份的良好习惯
gitlab-ctl stop # 停止所有 gitlab 组件：
# 更新gitlab包
yum update gitlab-ce直接编辑源 /etc/yum.repos.d/gitlab-ce.repo，安装 GitLab 社区版
yum list gitlab-ce # 查看版本
sudo yum install gitlab-ce #(自动安装最新版)
sudo yum install gitlab-ce-8.15.2-ce.0.el6 #(安装指定版本)注意：10.7 版本升级到 11.x 版本需要先升级到 10.8 版本
# 安装指定版本 10.8 的版本
sudo yum install gitlab-ce-10.8.0-ce.0.el6安装完成记得将所有服务启起来哦
gitlab-ctl start # 启动所有数据库
# postgresql 数据库如果启动不了，通过重启启动
gitlab-ctl restart postgresql安装过如果报错，查看提示根据提示操作，版本跨度太大会报错哦。
