如何让nginx在启动时不对proxy_pass中的主机名进行dns解析检查

Question

nginx在启动时，会对proxy_pass中的主机名进行dns解析，如果解析失败就停止启动。

 [emerg] 1#1: host not found in upstream "q_web"

nginx的配置如下：

server {
  listen 80;
  server_name q.cnblogs.com;
  access_log off;

  location / {
    resolver 127.0.0.11;
    proxy_set_header Host $host;
    proxy_pass http://q_web;
  }
}

请问如何可以躲过这个dns解析检查让nginx先启动起来？
