sudo yum install -y curl openssh-server openssh-clients cronie
sudo lokkit -s http -s ssh
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install -y gitlab-ce
sudo gitlab-ctl reconfigure
完成后有下面几处要进行更改：
[root@centos3 ~]# vim /etc/gitlab/gitlab.rb
external_url 'http://192.168.2.22' #设置git地址
gitlab_rails['backup_path'] = "/date/gitlab/backups" #设置备份的目录。
# git_data_dirs({
# "default" => {
# "path" => "/mnt/nfs-01/git-data",
# "failure_count_threshold" => 10,
# "failure_wait_time" => 30,
# "failure_reset_time" => 1800,
# "storage_timeout" => 5
# }
# })
创建备份：
gitlab-rake gitlab:backup:create
执行完成后，就备份成功，在备份目录下回有个.,tar的包：
备份恢复：
gitlab-rake gitlab:backup:restore BACKUP=1503886015_2017_08_28_9.5.1
注意：BACKUP的值取的是备份包1503886015_2017_08_28_9.5.1_gitlab_backup.tar的“_gitlab_backup.tar”前面的部分，这样就恢复到指定的版本，上面的备份可以写一个定时任务，定时执行。
安装完成后 ，去另外的机器上执行:ssh -Tv [email protected],如果连接成功，那就ok，然后配置sshconfig
vim ~/.ssh/config
Host 10.40.2.22
RSAAuthentication yes
IdentityFile ~/.ssh/config/private-key-filename-01
如果不加上面的这段，git clone http://10.40.2.22/soa/gbl.git没有问题，但是git clone [email protected]:soa/gbl.git,会报错ssh链接呗拒绝，还有必须是git的版本是2.0以上，硬性要求，不然 clone的时候会爆401认证的问题，没法clone代码
新版的页面改动比较大：
ssh认证
user group project添加：
新用户设置密码：
新创建用户liujiang，设置密码：
group组人员权限变更：
设置项目管理者：
这个置顶用户成为owner ，就可以对这个组进行用户的添加和删除
修改gitlab时区：
[root@liujiangbu gitlab]# vim /etc/gitlab/gitlab.rb
# gitlab_rails['time_zone'] = 'UTC'
gitlab_rails['time_zone'] = 'Asia/Shanghai'
### Email Settings
# gitlab_rails['gitlab_email_enabled'] = true
gitlab-ctl reconfigure
合并：
命令行修改密码：
(http://docs.gitlab.com/ce/security/reset_root_password.html#how-to-reset-your-root-password)
Log into your server with root privileges. Then start a Ruby on Rails console.
Start the console with this command:
gitlab-rails console production
Wait until the console has loaded.
There are multiple ways to find your user. You can search for email or username.
user = User.where(id: 1).first
or
user = User.find_by(email: '[email protected]')
Now you can change your password:
user.password = 'secret_pass'
user.password_confirmation = 'secret_pass'
It's important that you change both password and password_confirmation to make it work.
Don't forget to save the changes.
user.save!
