在nginx中创建虚拟主机以托管NodeJS应用程序

Question

以前，我使用Apache代理托管了我的NodeJS应用程序，并在虚拟主机中进行了以下配置。

<VirtualHost *:80> 
    ServerName api.mydomain.com 
    ProxyPreserveHost On 
    ProxyPass/http://localhost:8090/ 
    ProxyPassReverse/http://localhost:8090/ 
    ErrorLog ${APACHE_LOG_DIR}/error.log 
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
</VirtualHost> 

现在我已经搬到NGINX因为GitLab依赖。

现在虚拟主机/etc/nginx/sites-available/api.mydomain.com

server { 
    listen 80; 

    server_name api.mydomain.com; 

    location/{ 
     proxy_pass http://localhost:8090; 
     proxy_http_version 1.1; 
     proxy_set_header Upgrade $http_upgrade; 
     proxy_set_header Connection 'upgrade'; 
     proxy_set_header Host $host; 
     proxy_cache_bypass $http_upgrade; 
    } 
} 

下，但域加载主主机内容，而不是应用程序的NodeJS。

nginx的版本nginx/1.10.1，Ubuntu的版本16.04

下面是唯一的另一台虚拟主机，我有gitlab，

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

## Normal HTTP host 
server { 
    ## Either remove "default_server" from the listen line below, 
    ## or delete the /etc/nginx/sites-enabled/default file. This will cause gitlab 
    ## to be served if you visit any address that your server responds to, eg. 
    ## the ip address of the server (http://x.x.x.x/)n 0.0.0.0:80 default_server; 
    listen 0.0.0.0:80 default_server; 
    listen [::]:80 default_server; 
    server_name gitlab.mydomain.com 
    server_tokens off; ## Don't show the nginx version number, a security best practice 
    root /opt/gitlab/embedded/service/gitlab-rails/public; 

    ## See app/controllers/application_controller.rb for headers set 

    ## Individual nginx logs for this GitLab vhost 
    access_log /var/log/nginx/gitlab_access.log; 
    error_log /var/log/nginx/gitlab_error.log; 

    location/{ 
    client_max_body_size 0; 
    gzip off; 

    ## https://github.com/gitlabhq/gitlabhq/issues/694 
    ## Some requests take more than 30 seconds. 
    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; 
    } 
}

你可能还没有创建在sites-enabled一个符号链接指向配置在sites-available，所以配置实际上没有读取。
