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
