军哥lnmp1.7重启后nginx无法自启

一开始都是正常的，服务器重启nginx还会自动启动，突然今天重启服务器，发现网站打不开了，systemctl status nginx，提示

使用nginx -t，检查没问题
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

输入journalctl -xe，向上翻几页，看到：

手动输入 systemctl start nginx，可以启动，网站可以正常打开，输入systemctl status nginx，提示：

有大神知道什么原因吗？

不知道，紫薯布丁，楼下解答

caddy

没看你日志，这样看日志看得眼花，系统直接看，错误部分是可以标红

试下重激活看看

systemctl enable nginx.service

llyang

systemctl enable nginx
reboot
systemctl status nginx
看看啥情况，理论上应该没问题

如果不行，查看log报告

输入systemctl enable nginx.service后，重启，还是不会自启

systemctl enable nginx
reboot
systemctl status nginx

试过，还是不行，是查看/usr/local/nginx/logs/error.log吗？

检查一下LOG档是否太大 空间满了 也会这样

fcurrk

用军哥的命令管理nginx。

唐王李世民

查看你的nginx配置或网站配置

如果有这个文件，就是的。

如果没找到这个文件，在.conf中查找这个文件。文件名称、位置，都在这里定义。
