官方安装教程

  1. Install and configure the necessary dependencies

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
  1. Add the GitLab package server and install the package
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

curl -LJO https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/6/gitlab-ce-XXX.rpm/download
rpm -i gitlab-ce-XXX.rpm
  1. Configure and start GitLab
sudo gitlab-ctl reconfigure
  1. Browse to the hostname and login

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.

解决官方无法安装的情况

编辑源

使用清华大学 TUNA 镜像源 打开网址将内容复制到gitlab-ce.repo文件中，编辑路径vim /etc/yum.repos.d/gitlab-ce.repo

[gitlab-ce]
name=gitlab-ce
baseurl=http://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el6
repo_gpgcheck=0
gpgcheck=0

gpgkey=https://packages.gitlab.com/gpg.key

更新本地 YUM 缓存

sudo yum makecache

安装 GitLab 社区版

sudo yum install gitlab-ce #(自动安装最新版)
sudo yum install gitlab-ce-8.8.4-ce.0.el6 #(安装指定版本)

更改配置

 vim /etc/gitlab/gitlab.rb
 # 找到 external_url 'http://000.00.00.00:8081'
 # 修改成你的地址

配置并启动GitLab

# 打开`/etc/gitlab/gitlab.rb`,
# 将`external_url = 'http://git.example.com'`修改为自己的IP地址：`http://xxx.xx.xxx.xx`，
# 然后执行下面的命令，对GitLab进行编译。
sudo gitlab-ctl reconfigure

登录GitLab

Username: root 
Password: 5iveL!fe

GitLab头像无法正常显示

原因：gravatar被墙 解决办法： 编辑 /etc/gitlab/gitlab.rb，将

# gitlab_rails['gravatar_plain_url'] = 'http://gravatar.duoshuo.com/avatar/%{hash}?s=%{size}&d=identicon'

修改为：

gitlab_rails['gravatar_plain_url'] = 'http://gravatar.duoshuo.com/avatar/%{hash}?s=%{size}&d=identicon'

然后在命令行执行：

sudo gitlab-ctl reconfigure 
sudo gitlab-rake cache:clear RAILS_ENV=production

nginx配置

解决 80 端口被占用

upstream gitlab {
     server 114.55.111.111:8081 ;
}
server {
    #侦听的80端口
    listen       80;
    server_name  git.diggg.cn;
    location / {
        proxy_pass   http://gitlab;    #在这里设置一个代理，和upstream的名字一样
        #以下是一些反向代理的配置可删除
        proxy_redirect             off;
        #后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
        proxy_set_header           Host $host;
        proxy_set_header           X-Real-IP $remote_addr;
        proxy_set_header           X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size       10m; #允许客户端请求的最大单文件字节数
        client_body_buffer_size    128k; #缓冲区代理缓冲用户端请求的最大字节数
        proxy_connect_timeout      300; #nginx跟后端服务器连接超时时间(代理连接超时)
        proxy_send_timeout         300; #后端服务器数据回传时间(代理发送超时)
        proxy_read_timeout         300; #连接成功后，后端服务器响应时间(代理接收超时)
        proxy_buffer_size          4k; #设置代理服务器（nginx）保存用户头信息的缓冲区大小
        proxy_buffers              4 32k; #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置
        proxy_busy_buffers_size    64k; #高负荷下缓冲大小（proxy_buffers*2）
        proxy_temp_file_write_size 64k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传
    }
}

# 检查配置
/usr/local/nginx-1.5.1/sbin/nginx -tc conf/nginx.conf

# nginx 重新加载配置
/usr/local/nginx-1.5.1/sbin/nginx -s reload

运维

# 启动所有 gitlab 组件：
sudo gitlab-ctl start

# 停止所有 gitlab 组件：
sudo gitlab-ctl stop

# 重启所有 gitlab 组件：
sudo gitlab-ctl restart

# 查看服务状态
sudo gitlab-ctl status

# 启动服务
sudo gitlab-ctl reconfigure

# 修改默认的配置文件
sudo vim /etc/gitlab/gitlab.rb

# 查看版本
sudo cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

# echo "vm.overcommit_memory=1" >> /etc/sysctl.conf
# sysctl -p
# echo never > /sys/kernel/mm/transparent_hugepage/enabled

# 检查gitlab
gitlab-rake gitlab:check SANITIZE=true --trace

# 查看日志
sudo gitlab-ctl tail

备份恢复

Gitlab 创建备份

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:

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。

Gitlab 修改备份文件默认目录

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'

修改后使用gitlab-ctl reconfigure命令重载配置文件。

备份

0 2 * * * /usr/bin/gitlab-rake gitlab:backup:create
0 2 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create

恢复

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
# ok: down: unicorn: 0s, normally up
gitlab-ctl stop unicorn  
# ok: down: sidekiq: 0s, normally up
gitlab-ctl stop sidekiq

# 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=xxxxxx

# 启动Gitlab
sudo gitlab-ctl start
