What's the problem with Nginx failing to start? Today, I saw a netizen deploy the pagoda panel on the server, and Nginx failed to start automatically. Here, we need to help him find out what the problem is.

If Nginx fails to start, it may be due to one of the following reasons:
1. Configuration error
We need to check whether the configuration file of Nginx is correct. have access to nginx -t
The command tests whether the syntax of the configuration file is correct. If you don't trust us, we can uninstall Nginx and reinstall a new version. After all, when using the pagoda panel, the software is visual and can be uninstalled at will.
2. Port occupation
If another process is already using the port Nginx is listening on, Nginx will fail to start. You can execute netstat -tlnp | grep <port>
Command to check whether the port has been occupied.
3. Permission issues
Nginx may not have sufficient permissions to start. Please ensure that the running user of Nginx has appropriate permissions, such as reading configuration files and accessing log files.
4. Log corruption
If the file that Nginx records the error log is damaged or the permissions are set incorrectly, it may also cause Nginx to fail to start. Please check the relevant log files and make necessary repairs.
If we are afraid of trouble in the following 2-4 problems, I usually use the first method. Uninstall and reinstall directly.
