我在 Debian 上运行 Plesk 因为我大约 6 个月前安装了 Plesk，每次重新启动服务器时 nginx 都无法在启动时启动，我必须手动重新启动它。今天我需要再次重新启动服务器，但这一次我什至无法手动重新启动 nginx。
我明白了：
Starting nginx (via systemctl): nginx.serviceJob for nginx.service failed.
See 'systemctl status nginx.service' and 'journalctl -xn' for details.
failed!
systemctl status nginx.service 返回：

任何帮助将不胜感激！
提前致谢！
答案1
嗯，这很尴尬。因此，在查看重复出现的模式“（99：无法分配请求的地址）”之后，我决定查看分配 IP 地址的服务器，结果发现它没有获取静态 IP 地址，而是获取了动态 IP 地址。
更正此问题后，我能够重新启动 nginx。希望其他人能够从中受益。
