nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol) 错误

centos6.8环境

修改nginx配置文件后，重启报错：

nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)

解决办法：

vim /etc/nginx/conf.d/default.conf
将
listen       80 default_server;
listen       [::]:80 default_server;


改为：
listen       80;

#listen       [::]:80 default_server;

重新启动nginx即可，网上说的那种kill掉nginx进程和ipv6 on的方法不适用
