精更新最新版本系统后，飞牛Web网页无法打开

首先使用SSH连接飞牛，并且进入root权限

发现端口 8000 5666 nginx 都监听着，但就是访问不了，一直转圈···

nginx error.log:

一般到上一步就可以解决了，但是有个别用户的还是无法解决？

比如：提示启动trim_nginx失败！

继续使用如下命令查看错误详情：

journalctl -xeu trim_nginx.service

░░ Support: https://www.debian.org/support

Apr 02 22:24:06 chao nginx[17062]: nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

这个日志显示trim_nginx被占用，我们可以看下哪个进程占用了nginx的80端口：

root@chao:~# lsof -i:80
COMMAND   PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

我们发现有一个nginx占用了飞牛的5666进程所在的那个nginx进程（trim_nginx），导致web页面无法访问

解决方案：直接杀死该nginx进程即可，可以使用如下命令

systemctl stop nginx

然后我们继续启动飞牛的nginx，即trim_nginx，具体命令如下：

systemctl restart trim_nginx

然后，我们发现linux命令行没有报错，刷新飞牛的web页面发现可以正常访问飞牛啦！
