Nginx配置多端口多域名访问的实现

在一个服务器上部署多个站点，需要开放多个端口来访问不同的站点，流程很简单，调试花了2小时，记录一下：

主域名多端口访问

在DNS NameServer设置A记录

将 www.xxx.com 指向服务器ip

开放所需端口，修改nginx配置文件

比如我们有两个服务分别开放在80端口和8080端口

如果有iptable，先开放端口：

iptables -A INPUT -ptcp --dport 80 -j ACCEPT
iptables -A INPUT -ptcp --dport 8080 -j ACCEPT

修改配置文件:

#path: /usr/local/nginx/conf/nginx.conf

server {
listen 80;
server_name www.xxx.com;
access_log /data/www/log/33.33.33.33_nginx.log combined;
index index.html index.htm index.php;
include /usr/local/nginx/conf/rewrite/none.conf;
root /data/www/website/33.33.33.33:80;


location ~ [^/]\.php(/|$) {
  fastcgi_pass unix:/dev/shm/php-cgi.sock;
  fastcgi_index index.php;
  include fastcgi.conf;
  }
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
  expires 30d;
  access_log off;
  }
location ~ .*\.(js|css)?$ {
  expires 7d;
  access_log off;
  }
}
server {
listen 8080;
server_name A.xxx.com;
access_log /data/www/log/33.33.33.33:8080_nginx.log combined;
index index.html index.htm index.php;
include /usr/local/nginx/conf/rewrite/none.conf;
root /data/www/website/33.33.33.33:8080;


location ~ [^/]\.php(/|$) {
  fastcgi_pass unix:/dev/shm/php-cgi.sock;
  fastcgi_index index.php;
  include fastcgi.conf;
  }
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
  expires 30d;
  access_log off;
  }
location ~ .*\.(js|css)?$ {
  expires 7d;
  access_log off;
  }
}

关键就是两个 server 段配置，你也可以把这两段拆成两个配置文件，放到

/etc/nginx/conf.d/

目录下面；

子域名多端口访问

这种访问比较傻，因为你的8080端口的访问需要 http://xxx.com:8080 这样的格式；

而且如果有两个不同的cgi，比如80端口对应一个php web服务， 8080端口对应一个nodejs web服务；而我们的nodejs自带web服务，已经在8080端口监听了，这怎么办？

这个时候我们需要Nginx的反向代理功能，并在DNS Server上面增加一条A记录，最终实现

• www.xxx.com 访问80端口
• A.xxx.com 通过nginx转发访问8080端口服务

增加一条A记录

将 A.xxx.com 指向服务器ip

Nginx配置模板如下：

#path: /usr/local/nginx/conf/nginx.conf

server {
  listen 80;
  server_name www.xxx.com;
  access_log /data/www/log/33.33.33.33_nginx.log combined;
  index index.html index.htm index.php;
  include /usr/local/nginx/conf/rewrite/none.conf;
  root /data/www/website/33.33.33.33:80;


  location ~ [^/]\.php(/|$) {
    fastcgi_pass unix:/dev/shm/php-cgi.sock;
    fastcgi_index index.php;
    include fastcgi.conf;
    }
  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
    expires 30d;
    access_log off;
    }
  location ~ .*\.(js|css)?$ {
    expires 7d;
    access_log off;
    }
}

server {
  listen 80;
  listen [::]:80;

  server_name A.XXX.com;

  proxy_connect_timeout 300s;
  proxy_send_timeout 300s;
  proxy_read_timeout 300s;
  fastcgi_send_timeout 300s;
  fastcgi_read_timeout 300s;

  location / {
    proxy_pass  http://127.0.0.1:3000;
    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;
    try_files $uri $uri/ =404;
  }
}

nginx重新载入配置文件

nginx -s reload
