NGINX 反向代理和多个应用程序的配置

NGINX 反向代理和多个应用程序的配置

我是 NGINX 的新手，它确实让我头疼......

我有一台运行着多项服务的服务器：confluent/kafka、grafana。这些服务中的每一个都可以通过 http://:port 从域中的其他计算机访问。

我想使用 HTTPS 反向代理这些服务以提高安全性，以便 confluent 和 grafana 只能通过 URI 访问

  • https://<hostname>/grafana
  • https://<hostname>/confluent
  • https://<hostname>/more to come

好的，也会

  1. https://grafana.<hostname>
  2. https://confluent.<hostname>
  3. https://more_to_come.<hostname>
  4. 项目清单

到目前为止我有一个 nginx.conf（或多或少是默认模板）：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 768;
        # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off;

    server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
    ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
   ##
    # Gzip Settings
    ##

    gzip on;
    gzip_disable "msie6";

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;
    # gzip_buffers 16 8k;
    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}
... # mail all commented out

如果没有其他文件（服务器配置），我在.works中创建了两个*.conf文件：conf.dgrafana.conf*.conf

server {

  listen 80;
  listen [::]:80;

  listen 443 ssl;
  ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
  ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

  root /var/www/<hostname>/html;
  index index.html index.htm;

  server_name <hostname>;

  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Server $host;
  }
}

注意： 处有一个虚拟网页/var/www/<hostname>/html/index.html。但是，如果我只有一个，grafana.conf则不会将其拉出，而是拉出 URI 处的 Grafana 应用程序https://<hostname>（或多或少符合预期）。

如果我添加另一个.conf文件，请confluent.conf像这样：

server {

  listen 80;
  listen [::]:80;

  listen 443 ssl;
  ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
  ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

  root /var/www/<hostname>/confluent/html;
  index index.html index.htm;

  server_name <hostname>;

  location /confluent {
    proxy_pass http://localhost:9091;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Server $host;
  }
}

系统返回：

  • http://<hostname>-->/var/www/<hostname>/html/index.html
  • https://<hostname>-->/var/www/<hostname>/html/index.html
  • https://<hostname>/confluent-->502 Bad Gateway

我会坚持使用单服务器配置，使用映射来定义每个主机名的根和池。如下所示：

map $http_host $docroot {
    grafana.statnamen.de /var/www/www.statnamen.de/html;
    confluent.statnamen.de /var/www/www.statnamen.de/confluent/html;
    moretocome.statnamen.de /var/www/www.statnamen.de/moretocome/html;
    default /var/www/html;
}

map $http_host $pool {
    grafana.statnamen.de localhost:3000;
    confluent.statnamen.de localhost:9091;
    moretocome.statnamen.de 127.0.0.1:9092;
    default 127.0.0.1:3000;
}


server {

    listen 80;
    listen [::]:80;

    listen 443 ssl;
    ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
    ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

    root /var/www/$docroot;
    index index.html index.htm;

    server_name grafana.statnamen.de confluent.statnamen.de moretocome.statnamen.de;

    location / {
        proxy_pass http://$pool;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Server $host;
    }
}
