Comment résoudre le problème de nginx configurant plusieurs sites pour partager le port 80

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

  include       /etc/nginx/mime.types;
  default_type    application/octet-stream;
  include /usr/local/nginx/default.d/*.conf; //就这里加一行就可以了
}

server {
  listen    80 ;  //注意这里，要把默认的那个default_server去掉,因为我们在下面要单独配置域名访问，所以这里不要留default_server，不然会报错。
  server_name mytest.com; //这里写你想设置的域名，可以写多个，与名之间用空格隔开
  root     /mnt/share/mytest.com;  //这里是你虚拟机的根目录，写绝对路径
  # Load configuration files for the default server block.

  location / {
    index index.php index.html index.htm; //这里配置默认访问的页面
  }
  location ~* \.php$ {  //这里配置php解析.php文件

    fastcgi_index  index.php;
    fastcgi_pass  127.0.0.1:9000;
    include     fastcgi_params;
