Configuration Details After Install Nginx:
Service Management
The Service section allows you to manage the Nginx service by performing the following actions:
- Start
- Stop
- Restart/Reload
Reloading the service applies configuration changes without interrupting active connections, whereas restarting the Nginx service completely restarts it.
Web Server:
The Web Server section supports multi-web server hosting. Unless you have a specific requirement, it is recommended to keep the default configuration unchanged.
Configuration File:
The Config File option opens the main nginx.conf configuration file, where you can modify the global Nginx settings.
After making configuration changes, always verify the syntax before reloading the service by running the following command:
nginx -tIf the configuration test completes successfully, you can safely reload Nginx to apply the changes.
Switch Version:
The Switch Version feature allows you to upgrade or downgrade the installed version of Nginx.
This is useful when you need:
- New features

Load Status:
The Load Status section provides real-time information about the Nginx server, including:
- Active connections
- Accepted requests
- Handled requests
- Request processing statistics
These metrics help monitor server performance and identify potential bottlenecks.
Optimization:
The Optimization feature recommends performance settings based on your server’s available resources.
It can automatically optimize parameters such as:
- Worker processes
- Worker connections
- Connection limits
- Buffer sizes
Applying these recommendations can improve overall server performance and efficiently handle increased website traffic.
Error Log:
The Error Log records errors and warning messages generated by Nginx.
This should be the first place to check when troubleshooting website issues such as:
