配置nginx的端口来访问不同网站

可以.在配置nginx.conf里的http下配置两个server即可:
server {
    listen 81;
    root   /path/to/site1;
    index index.html index.htm index.php;
    location ~ \.php$ {
        try_files $uri =404;
        include fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}
server {
    listen 82;
    root   /path/to/site2;
    index index.html index.htm index.php;
    location ~ \.php$ {
        try_files $uri =404;
        include fastcgi_params;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}
