Nginx如何配置多端口多域名访问

时间：2023-05-12 14:12

主域名多端口访问

在dns nameserver设置a记录

将指向服务器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 acceptiptables -a input -ptcp --dport 8080 -j accept

修改配置文件:

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