Understanding NGINX Restart vs. Reload
NGINX provides a range of commands for controlling its operational state, but users frequently get confused between the restart and reload commands.
At first glance, both actions seem identical and seem to carry out the same task of restarting the service.
Nevertheless, when approached from a technical standpoint, the two actions display distinct dissimilarities and yield contrasting results.
Let’s delve into the specifics of these actions.
To restart the NGINX web server in Linux, the systemctl tool can be utilized.
When NGINX is restarted, it undergoes a two-step process: first, the server is completely shut down and then it is started again. This process involves closing all ongoing connections and worker processes before initiating a new instance of the server.
Determining the appropriate moment to restart the NGINX web server
You should restart an NGINX server for:
Major Configuration Changes
If you have made important changes to the NGINX configuration, such as modifying server blocks, adjusting ports, or changing the number of worker processes, it is necessary to restart the server.
Module Additions/Removals
It is necessary to restart the server after adding or removing an NGINX module. This is because the modules are integrated into the system during the start-up phase of the restart process.
To reboot the NGINX server in Linux using systemctl, execute the given command.
Restarting Nginx using the command "sudo systemctl restart nginx."
Please be aware that if you restart the server, it may temporarily interrupt ongoing connections and could have an impact on user satisfaction. We highly recommend scheduling server restarts at times when there is less traffic.
To reload NGINX configuration on Linux, you can utilize the systemctl command.
While swapping the old configuration for the new one, the NGINX server remains active throughout the reloading process.
The NGINX master process stays operational to keep active connections running smoothly. The updated configuration spawns new worker processes, and the older ones are gracefully terminated once they finish their ongoing tasks.
When should the NGINX server configuration be reloaded?
There are various scenarios where you should contemplate reloading the NGINX server configuration:
Minor Configuration Tweaks
If you make any changes, such as editing redirect rules, adding MIME types, or adjusting rate limiting, it is advisable to reload the server configuration.
Certificate Renewals
It is important to refresh the NGINX server configuration every time you make changes to SSL certificates.
Frequent Changes

To reload the configuration of the NGINX server in Linux using systemctl, execute the following command.
Reloading Nginx using the sudo systemctl command.
Important : Prior to reloading, examine the configuration file to check for any syntax errors by conducting a test. nginx -t It is advisable to follow good practices. If the configuration is faulty, a failed reload could cause service disruption and necessitate a complete server restart.
If NGINX identifies a syntax error while reloading, it terminates the process. However, the server still operates using the previous configuration, ensuring uninterrupted server functionality and a seamless user experience.
Start or stop the NGINX service automatically on system startup in Linux by utilizing the systemctl command.
In order for NGINX to start automatically when the system starts up, you will need to enable it using the given command.
Enable the nginx service using the sudo systemctl command.
On the other hand, if you prefer not to have the NGINX service automatically start when the system is booted, you can use the command below.
Disable the nginx service using the sudo command and the systemctl command.
These are only a couple of the numerous managerial procedures. Here is an in-depth analysis of the functioning process of dedicated servers.
Problems that are frequently encountered with NGINX and their easy solutions.
