How often do you restart ngnix service on Linux webserver? This blog post will cover various ways to restart Nginx on a Linux system via command line and on Nginx running in a docker container. I have covered on both on a Systemd server and SysV init\/Upstart system.<\/p>\n

Open your terminal and login with root\/sudo user to run below shown commands.<\/p>\n

Restart Nginx HTTP server<\/h2>\n

CentOS 7, Ubuntu 18.04 and Ubuntu16.04 are a systemd operating system. To restart nginx service, you’ll need to use systemctl command<\/a> line tool.<\/p>\n

It is recommended to check syntax before restarting nginx service,<\/p>\n

$ sudo nginx -t
\n$ sudo systemctl restart nginx<\/p>\n

If you’re restarting after modifying nginx service unit file, you need to reload systemd first<\/p>\n

$ sudo systemctl daemon-reload<\/p>\n

Then restart nginx<\/p>\n

$ sudo systemctl restart nginx<\/p>\n

If you want to reload the configuration without restarting the service, i.e maintain current sessions, use<\/p>\n

sudo systemctl reload nginx<\/p>\n

Restarting Nginx on Upstart\/SysV init system<\/h2>\n

If you’re running a system with upstart or SysV init system. e.g Ubuntu 14.04, CentOS 6, you need to manage nginx service using the servicecommand.<\/p>\n

$ sudo service nginx restart<\/p>\n

You can also use an absolute path to init script, e.g<\/p>\n

sudo \/etc\/init.d\/nginx restart<\/p>\n

Restarting Nginx inside docker container<\/h2>\n

For nginx running inside a Docker container, it is advisable to reload the configuration instead of restarting the service.<\/p>\n

docker exec <nginx-container-name-or-id> nginx -s reload<\/p>\n

If you must restart the nginx process, then consider restarting the container using the command:<\/p>\n

$ docker restart <container name|id><\/p>\n

Example<\/p>\n

$ docker restart nginx<\/p>\n

Where nginx is the name of nginx container.<\/p>\n

Restarting nginx is a simple process but you need to be careful to ensure that any change made has correct syntax to avoid failure during a restart. The command used to check for configuration syntax is nginx -t<\/p>\n
