Nginx 无法启动，因为我犯了一个错误，不知道如何反转它

Question

I am following this tutorial in order to learn how to deploy flask-react applications from a singe nginx server, but I made the mistake of trying this command: $ sudo ln -s /etc/nginx/sites-available/react-flask-app.nginx /etc/nginx/sites-enabled/react-flask-app.nginx , but it happens that my file has no nginx extension, so the command should have been $ sudo ln -s /etc/nginx/sites-available/react-flask-app /etc/nginx/sites-enabled/react-flask-app . Now nginx refuses to start with command sudo systemctl start nginx , and command systemctl status nginx.service returns the following:

Dec 14 16:32:21 ip-172-31-5-99 systemd[1]: Starting A high performance web server and a reverse proxy server...
Dec 14 16:32:21 ip-172-31-5-99 nginx[2017]: nginx: [emerg] open() "/etc/nginx/sites-enabled/react-flask-app.nginx" failed (2: No such file or directory) in /etc/nginx/nginx.conf:62
Dec 14 16:32:21 ip-172-31-5-99 nginx[2017]: nginx: configuration file /etc/nginx/nginx.conf test failed
Dec 14 16:32:21 ip-172-31-5-99 systemd[1]: nginx.service: Control process exited, code=exited status=1
Dec 14 16:32:21 ip-172-31-5-99 systemd[1]: nginx.service: Failed with result 'exit-code'.
Dec 14 16:32:21 ip-172-31-5-99 systemd[1]: Failed to start A high performance web server and a reverse proxy server.

I don't know how to instruct nginx to forget about that file, I already stopped, started and reloaded nginx.

Answer 1

I found that a file with the name react-flask-app.nginx was created in /etc/nginx/sites-enabled , and such file contains the error message. I only deleted the file and everything went back to normal.
