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

entos6.5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
