## 修改gitlab配置文件

- 备份
> cp /opt/gitlab/service/nginx/run /opt/gitlab/service/nginx/run_copy

- 修改

``` bash
#源内容
#!/bin/sh
exec 2>&1

cd /var/opt/gitlab/nginxexec chpst -P /opt/gitlab/embedded/sbin/nginx -p
/var/opt/gitlab/nginx
#新内容
#!/bin/sh
exec 2>&1

cd /usr/local/nginx
exec chpst -P /usr/local/nginx/sbin/nginx -p
/usr/local/nginx
```

## nginx 增加虚拟主机配置

``` bash
# gitlab socket 文件地址
upstream gitlab {
  # 7.x 版本在此位置
  # server unix:/var/opt/gitlab/gitlab-rails/tmp/sockets/gitlab.socket;
  # 8.0 位置
  server unix://var/opt/gitlab/gitlab-rails/sockets/gitlab.socket;
}

server {
  listen *:8081;

  server_name gitlab.liaohuqiu.com;   # 请修改为你的域名

  server_tokens off;     # don't show the version number, a security best practice
  root /opt/gitlab/embedded/service/gitlab-rails/public;

  # Increase this if you want to upload large attachments
  # Or if you want to accept large git objects over http
  client_max_body_size 250m;

  # individual nginx logs for this gitlab vhost
  access_log  /var/log/gitlab/nginx/gitlab_access.log;
  error_log   /var/log/gitlab/nginx/gitlab_error.log;

  location / {
    # serve static files from defined root folder;.
    # @gitlab is a named location for the upstream fallback, see below
    try_files $uri $uri/index.html $uri.html @gitlab;
  }

  # if a file, which is not found in the root folder is requested,
  # then the proxy pass the request to the upsteam (gitlab unicorn)
  location @gitlab {
    # If you use https make sure you disable gzip compression 
    # to be safe against BREACH attack

    proxy_read_timeout 300; # Some requests take more than 30 seconds.
    proxy_connect_timeout 300; # Some requests take more than 30 seconds.
    proxy_redirect     off;

    proxy_set_header   X-Forwarded-Proto $scheme;
    proxy_set_header   Host              $http_host;
    proxy_set_header   X-Real-IP         $remote_addr;
    proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header   X-Frame-Options   SAMEORIGIN;

    proxy_pass http://gitlab;
  }

  # Enable gzip compression as per rails guide: http://guides.rubyonrails.org/asset_pipeline.html#gzip-compression
  # WARNING: If you are using relative urls do remove the block below
  # See config/application.rb under "Relative url support" for the list of
  # other files that need to be changed for relative url support
  location ~ ^/(assets)/  {
    root /opt/gitlab/embedded/service/gitlab-rails/public;
    # gzip_static on; # to serve pre-gzipped version
    expires max;
    add_header Cache-Control public;
  }

  error_page 502 /502.html;
}
```

## 禁用自带 nginx

``` bash
vim /etc/gitlab/gitlab.rb

# 修改
nginx['enable'] = false
```

## 重启 nginx, 重启gitlab

``` bash
sudo /usr/local/nginx/sbin/nginx -s reload
sudo gitlab-ctl reconfigure
```

## 权限配置

访问会报502。原本是 nginx 用户无法访问gitlab用户的 socket 文件，用户权限配置，因人而异。粗暴地:
> sudo chmod -R o+x /var/opt/gitlab/gitlab-rails
