server {
  listen       80;  //监听的端口号
  server_name  localhost;  //用域名方式访问的地址

  #charset koi8-r; //编码
  #access_log  /var/log/nginx/host.access.log  main;  //访问日志文件和名称

  location / {
      root   /usr/share/nginx/html;  //静态文件根目录
      index  index.html index.htm;  //首页的索引文件
  }

  #error_page  404              /404.html;  //指定错误页面

  # redirect server error pages to the static page /50x.html

  error_page   500 502 503 504  /50x.html; 
   当路径是/50x.html去找/usr/share/nginx/html里面的文件
  location = /50x.html {
      root   /usr/share/nginx/html;
  }
