root@s45-***:/home/arabico# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
nginx: configuration file /etc/nginx/nginx.conf test failed

root@s45***:/home/arabico# sudo nginx
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)

请如何让它开始

Answer 1

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

从错误消息看来，您的服务器上禁用了 ipv6。编辑 nginx 默认服务器配置并将其更改为仅侦听 ipv4 或启用 ipv6。

listen 80 default_server;
# comment to disable ipv6
# listen [::]:80 default_server;

Answer 2

只是我删除了这一行

听 [::]:80 default_server ipv6only=on;

从

/etc/nginx/sites-available/default 并且它有效：D
