Linux Restart Nginx Webserver
To restart the nginx web server use any one of the following command as a root user as per your Linux distro. Open a terminal or login to the remote server using ssh. For instance:
ssh vivek@server1.cyberciti.biz
sudo systemctl nginx [command]
Debian/Ubuntu/RHEL/CentOS Linux
Linux restart Nginx webserver, run:
# /etc/init.d/nginx restart
OR
# /etc/init.d/nginx reload
One can use the service command for sysv init based systems:
# service nginx restart
OR
# service nginx reload
If you are using systemd based Linux distro:
$ sudo systemctl restart nginx
OR
$ sudo systemctl reload nginx
To view status:
# service nginx status
OR
$ sudo systemctl status nginx

Fig.01: Restarting or reloading Nginx server
Using nginx command
Nginx has in built option to send signal to a master process. This should work with any Linux distributions or Unix-like operating systems. The syntax is as follows:
nginx - s signal
Reload Nginx Webserver
# nginx -s reload
OR
# /path/to/full/nginx -s reload
Stop Nginx Webserver
# nginx -s stop
OR
# /path/to/full/nginx -s stop
Exit or Quit Nginx Webserver
# nginx -s quit
OR
# /path/to/full/nginx -s quit
If nginx compiled and installed from the source code
If nginx binary is installed at /usr/local/nginx/sbin/nginx, enter:
# /usr/local/nginx/sbin/nginx -s reload
How to Start, Stop, or Restart Nginx Server
Here is the summary of all commands that you can pass either to the systemctl command OR service command
Option | Description | Examples |
---|---|---|
start | Start the Nginx web server | sudo systemctl start nginx sudo service nginx start |
stop | Stop the Nginx on Linux | sudo systemctl stop nginx sudo service nginx stop |
restart | Stops and then starts the Nginx web server service | sudo systemctl restart nginx sudo service nginx restart |
reload | Gracefully restarts the Nginx service after config changes | sudo systemctl reload nginx sudo service nginx reload |
status | Get the service or server status in Linux | sudo systemctl status nginx sudo service nginx status |
How to check nginx server config errors
You need to pass the -t to the nginx command to test configuration and exit. For example:
nginx -t
Pass the -T to test configuration, dump it on screen and exit, run:
nginx -T
How to send signal to a Nginx
The syntax is as follows for Linux and Unix users:
nginx -s signal
Signal can be stop, quit, reopen and reload. For instance, we can send reload signal as follows as the root user:
# nginx -t
# nginx -s reload
See nginx docs here for more info.

The method used is largely determined by whether NGINX was installed via package manager or compiled from source, correct?
I guess so. If compiled from source use /path/to/nginx -s reload else use service nginx reload or service nginx restart
Thanks for you,
I always use “service nginx restart” after config nginx
