NGINX Cheat Sheet

-

 



To manage the Nginx web server on a Linux system using systemd (which is used by most modern Linux distributions including Ubuntu), you can use the `systemctl` command. Here are the common commands for starting, stopping, checking the status, and restarting Nginx:


1. **Check the status of the Nginx server**:

   ```bash

   sudo systemctl status nginx

   ```

   This command displays the current status of the Nginx server, including whether it is running or not, and recent log entries.


2. **Start the Nginx server**:

   ```bash

   sudo systemctl start nginx

   ```

   Use this command to start the Nginx service if it's not already running.


3. **Stop the Nginx server**:

   ```bash

   sudo systemctl stop nginx

   ```

   This command stops the Nginx server. It's useful if you need to halt the server for maintenance or any other purpose.


4. **Restart the Nginx server**:

   ```bash

   sudo systemctl restart nginx

   ```

   Restarting is typically needed when you have made configuration changes. This command stops the server and starts it again.


5. **Reload the Nginx configuration without dropping connections**:

   ```bash

   sudo systemctl reload nginx

   ```

   If you've made changes to the Nginx configuration files, you can use this command to apply the changes without interrupting ongoing connections. This is less disruptive than a full restart and is generally recommended for applying changes in a production environment.


These commands should cover most scenarios for managing the Nginx service on your server.

  To connect to SSH via the Mac Terminal, follow these steps: 1. Open Terminal: You can find it in Applications > Utilities > Terminal, or you can use Spotlight by pressing Command + Space, typing "Terminal," and hitting Enter. 2. Use the ssh command: The basic syntax is ssh username@hostname . For example, if your username is "myuser" and the IP address of the remote server is "123.456.789.0," you would type: ssh myuser@123.456.789.0 If you're connecting using a domain name, you can replace the IP address with the domain. 3. Enter your password: Once you press Enter, Terminal will ask for your password. 4.Type it in (you won't see any characters on the screen as you type for security reasons) and press Enter. And that's it! You should now be connected to the remote server via SSH. Remember to replace "myuser" and "123.456.789.0" with your actual username and the IP address or domain of your SSH server. If your serv...
