启动nginx报错，80 failed (97: Address family not supported by protocol)

最近想使用云服务器来部署自己的web应用。 利用yum install nginx安装了nginx后， 用命令service nginx start 启动时，出现错误如下

找到nginx的配置文件：

vim /etc/nginx/conf.d/default.conf

# # The default server # server {
    listen 80 default_server; listen [::]:80 default_server; server_name  _; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / {
    }

    error_page 404 /404.html; location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html; location = /50x.html {
    }

}

将

listen [::]:80 default_server; 

该部分注释掉即可
