Ubuntu Linux: Start / Restart / Stop Nginx Web Server
sudo systemctl restart nginx
OR
sudo service nginx restart
OR (older Ubuntu Linux version):
sudo /etc/init.d/nginx restart
The same commands can be used to start / stop / restart the nginx server on a Ubuntu Linux:
sudo systemctl start nginx sudo systemctl stop nginx sudo systemctl restart nginx |
OR
sudo service nginx start sudo service nginx stop sudo service nginx restart |
OR
sudo /etc/init.d/nginx start sudo /etc/init.d/nginx stop sudo /etc/init.d/nginx restart |
To view status of your server
Use any one of the following command:
sudo service status nginx
OR
sudo systemctl status nginx
Sample outputs:
? nginx.service - A high performance web server and a reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

A note about reload nginx server
It is also possible to use the following syntax to reload nginx server after you made changes to the config file such as nginx.conf:
sudo nginx -s reload
OR
sudo systemctl reload nginx
OR
sudo service nginx reload
Dealing with error messages on screen
If the nginx server failed to start or stop or restart, check for the syntax error:
nginx -t ## OR set path to config file and test for the errors ## nginx -c /etc/nginx/nginx.conf -t |
Sample outputs:
The following error indicate that the username “nginxf” does not exists on line # 2:
nginx: [emerg] getpwnam(“nginxf”) failed in /etc/nginx/nginx.conf:2
To fix this error, edit the file with a text editor such as vi/vim/joe etc:
sudo vi /etc/nginx/nginx.conf ## or edit and jump to line no. 2 ### sudo vi +2 /etc/nginx/nginx.conf |
Update config file. Save and close the file. Test is again:
nginx -t |
I also recommend that you check for nginx server log files for more info:
sudo tail -f /var/log/nginx/error.log
2015/03/19 02:49:30 [emerg] 43130#0: getpwnam("nginxf") failed in /etc/nginx/nginx.conf:2
2015/03/19 02:49:44 [emerg] 43145#0: getpwnam("nginxf") failed in /etc/nginx/nginx.conf:2
It is also possible to use the systemd systemctl and journalctl commands for details on errors:
$ sudo systemctl status nginx.service
$ sudo journalctl -xe
