最新版Gitlab 更改自带nginx 为自建nginx

一. gitlab 安装

  参考：https://www.cnblogs.com/weifeng1463/p/7714492.html

二. gitlab 配置

   禁用自带 nginx

vim /etc/gitlab/gitlab.rb

加入

nginx['enable'] = false

 重启gitlab

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart

 三. nginx 安装

  参考：https://blog.youkuaiyun.com/db3265613/article/details/84581930

 四. nginx 配置

如果服务器资源不充裕的情况下，我们不能让一个gitlab 独自霸占服务器，那么就需要给gitlab动刀子了。

当我试图在gitlab服务自带nginx上创建一个站点时，想当然的创建一个.conf文件再包含进去，
但是当我运行 gitlab-ctl reconfigure 发现现实并不是那么如意，nginx所有配置文件全都恢复默认了，
所以这条路不通了。

但是如果直接启动本机自带的nginx呢？不用试都会知道两个nginx 公用一个80会有冲突根本启动不了，
网上虽然有将gitlab 的gitlab改个名字，但是非常不靠谱，而且根本行不通。

那么只能把gitlab自带的nginx废弃掉，用自建的nginx扩展性才会更好。



更改Gitlab使用的nginx
禁用gitlab的nginx启动
vim /etc/gitlab/gitlab.rb

更改配置：

nginx['enable'] = false

2. 更改自建nginx.conf配置

因为gitlab里的nginx有自定义的参数配置，所以大部分都最好继续沿用
以下为我的nginx.conf配置，没有把gitlab的/opt/gitlab/embedded/conf/nginx.conf 完全拿来用，
因为发现有的项会导致自建nginx卡在Starting nginx位置

include vhost/*.conf;
include /var/opt/gitlab/nginx/conf/nginx-status.conf;
}
再直接把/var/opt/gitlab/nginx/conf/gitlab-http.conf，完整复制到自建nginx的conf/vhost目录，无需修改。

至此就已经完成了移植，新增站点就在vhost里添加配置文件了。
