nginx.service 的作业失败，因为控制进程退出并显示错误代码

Question

在网上研究了很长时间后我一无所获......

我正在尝试在 Ubuntu 18.04 VPS 上启动 Nginx：

nginx.service 的作业失败，因为控制进程退出并显示错误代码。

当我查看journalctl -xe这里时，我得到的是：

[date] [terminal name] sshd[16465]: pam_unix(sshd:auth): check pass; user unknown
[date] [terminal name] sshd[16465]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=200.108.
[date] [terminal name] sshd[16465]: Failed password for invalid user info from 200.108.143.6 port 35460 ssh2
[date] [terminal name] sshd[16465]: Received disconnect from 200.108.143.6 port 35460:11: Bye Bye [preauth]
[date] [terminal name] sshd[16465]: Disconnected from invalid user info 200.108.143.6 port 35460 [preauth]

谁能帮我？
