nginx.service 的作業失敗，因為控制進程退出並出現錯誤代碼

Question

在網上研究了很長時間，我什麼也沒找到......

我正在嘗試在 Ubuntu 18.04 VPS 上啟動 Nginx：

nginx.service 的作業失敗，因為控制進程退出並出現錯誤代碼。

當我查看journalctl -xe這裡時，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]

誰能幫我？
