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

1、找到nginx.conf文件或/etc/nginx/conf.d/default.conf文件

找到修改：

listen       80 default_server;

listen       [::]:80 default_server;

修改为:

listen       80;

#listen       [::]:80 default_server;

2、重启nginx

service nginx restart
