Gitlab和NGINX设置

我正在尝试配置现有的NGINX以在CentOS上使用Gitlab omnibus.我目前安装了另一个使用127.0.0.1:3838的应用程序(App A).到目前为止,我有NGINX设置,以便进入我的网站IP 12.345.678.910,我能够重定向到App A.我想设置Gitlab,以便当我转到12.345.678.910/gitlab时,它将我重定向到Gitlab.我的想法是在http://127.0.0.1:8081上运行Gitlab ,并让NGINX将12.345.678.910/gitlab重定向到localhost:8081.

我已按照这些链接寻求帮助:

https://docs.gitlab.com/omnibus/settings/nginx.html#using-a-non-bundled-web-server.

使用现有Nginx安装转发到GitLab子域

编辑/etc/gitlab/gitlab.rb

external_url = 'http://127.0.0.1:8081'
nginx['enable'] = false
web_server['external_users'] = ['nginx']

新配置文件/ etc/nginx/sites-enabled/gitlab

upstream gitlab-workhorse {
    server unix:/var/opt/gitlab/gitlab-workhorse/socket;
}

server {
  listen 0.0.0.0:8081;
  listen [::]:8081;
  server_name localhost;
  server_tokens off;
  root /opt/gitlab/embedded/service/gitlab-rails/public;

  access_log  /var/log/nginx/gitlab_access.log;
  error_log   /var/log/nginx/gitlab_error.log;

location / {
  client_max_body_size 0;
  gzip off;

  proxy_read_timeout      300;
  proxy_connect_timeout   300;
  proxy_redirect          off;
  proxy_http_version 1.1;
  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-Forwarded-Proto   $scheme;
  proxy_pass http://gitlab-workhorse;
 }
}

添加到/etc/nginx/conf.d/default.conf:

server {
    listen 80 default_server;
    server_name localhost;
location / {
    root /usr/share/nginx/html;
    index index.html index.htm;
}
location /gitlab {
    proxy_pass http://127.0.0.1:8081;
}

我已将'nginx'添加到gitlab-www组.跑nginx restart和gitlab重新配置命令.

sudo usermod -aG gitlab-www nginx
sudo service nginx restart
sudo gitlab-ctl reconfigure && gitlab-ctl restart

我在上面的链接中为每个评论安装了Passenger,但这并没有解决问题.所以当我转到12.345.678.910/gitlab时,我得到一个Page Not Found错误.

我仍然是这一切的新手,任何帮助将不胜感激.
