Nginx erreur它没有打开

请我服务器上的nginx确实启动了，请关注我

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)

如何让它开始

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

根据错误消息，您的服务器上似乎已禁用了ipv6。编辑nginx默认服务器配置，并将其更改为仅在ipv4上侦听或启用ipv6。

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

我只是删除了这一行

听[::]：80 default_server ipv6only = on;

从

/ etc / nginx / sites-available / default，它可以工作：D

感谢您提及ipv6。

就我而言，我在nginx conf中有一行

proxy_pass http://localhost:3028/;

当我在内核配置中禁用ipv6时，发生了问题。重新启用ipv6可以解决问题，但这不是我想要的。

解决的办法是删除

::1     localhost ip6-localhost ip6-loopback
ff02::1     ip6-allnodes
ff02::2     ip6-allrouters

在/etc/hosts。

因此，本地主机将始终遵循默认的ipv4目标，即127.0.0.1。

仅删除该::1行就足够了。由于ipv6已完全禁用，因此我将全部删除。

将localhostnginx配置更改为127.0.0.1也可以解决此问题。
