nginx配置多个域名使用同一个端口

nginx版本是1.21.0

随着服务器性能的提升和业务的需求，一台服务器上往往会同时有多个服务，这些服务都希望监听80端口，比如有a.xxx.com和b.xxx.com。如下筒单配置即可实现。

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  a.xxx.com;

        charset utf-8;

        access_log  logs/host.access.log  main;

        location / {
            root   /opt/a_xxx_com;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
    server {
        listen       80;
        server_name  b.xxx.com;

        charset utf-8;

        access_log  logs/host.access.log  main;

        location / {
            root   /opt/b_xxx_com;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }
