If you’re running a web server on Ubuntu, there’s a good chance you’re using Nginx as your web server software. Nginx is a popular open-source web server that is known for its speed, scalability, and ease of use. However, like any software, Nginx can encounter issues that require you to restart the service.

In this guide, we’ll walk you through the steps to restart Nginx on Ubuntu. Whether you’re a beginner or an experienced system administrator, this guide will help you quickly and easily restart Nginx on your Ubuntu server.

Prerequisites

Before we begin, you’ll need to have access to an Ubuntu server with Nginx installed. You should also have root or sudo privileges to execute commands.

Step 1: Check Nginx Status

Before you restart Nginx, you should check its status to see if it’s running. To do this, open a terminal window and run the following command:

sudo systemctl status nginx

If Nginx is running, you’ll see output similar to this:

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Tue 2021-08-10 17:20:52 UTC; 1 weeks 2 days ago
     Docs: man:nginx(8)
  Process: 12345 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
 Main PID: 12346 (nginx)
    Tasks: 2 (limit: 4704)
   Memory: 2.2M
   CGroup: /system.slice/nginx.service
           ├─12346 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
           └─12347 nginx: worker process

If Nginx is not running, you’ll see output similar to this:

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Tue 2021-08-10 17:20:52 UTC; 1 weeks 2 days ago
     Docs: man:nginx(8)
  Process: 12345 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
 Main PID: 12346 (code=exited, status=0/SUCCESS)

If Nginx is not running, you’ll need to start it before you can restart it.

Step 2: Stop Nginx

To restart Nginx, you’ll first need to stop the service. To do this, run the following command:

sudo systemctl stop nginx

This command will stop the Nginx service.

Step 3: Restart Nginx

Once you’ve stopped Nginx, you can restart it by running the following command:

sudo systemctl restart nginx

This command will restart the Nginx service.

Step 4: Verify Nginx Status

After you’ve restarted Nginx, you should verify its status to ensure that it’s running. To do this, run the following command:

sudo systemctl status nginx

If Nginx is running, you’ll see output similar to the output in Step 1.
