一年前我一直在使用Nginx＆PageSpeed。 但是，我安装了cerbot来发出Let's Encrypt SSL证书，并且该软件包自动重新安装了Nginx（当我的网站pipe理员安装它时从源代码运行）。
从那以后，Nginx被克隆到一个新的位置，并引发service nginx <stop|start|restart>命令的问题。 我已经手动删除了certbot安装的/usr/sbin/nginx目录，但是我仍然无法启动，停止或重新启动Nginx。
请注意，我的网站仍旧在旧的Nginx服务器上运行，并立即提供内容。 但是，如果我想更新我的Nginxconfiguration文件，我将无法重新启动Nginx。 如果我重新启动VPS，最有可能启动失败。
我怎样才能解决这个烦人的问题？ 我已经连续2小时寻找解决scheme。 这里是service nginx restart抛出的错误：
● nginx.service - A high performance web server and a reverse proxy server Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2017-10-11 19:57:53 EDT; 7s ago Process: 18479 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=203/EXEC) Main PID: 14066 (code=killed, signal=KILL) Oct 11 19:57:53 vps118687 systemd[1]: Starting A high performance web server and a reverse proxy server...

我也尝试入侵/etc/init.d/nginx文件，以解决可能的path问题。 无论如何，这里是/etc/init.d/nginx内容：

/usr/local/sbin/nginx -V工作并返回所有的Nginx安装版本和信息。
感谢您的回答。
