CentOS Setup Nginx Server: Step-by-Step Guide
Step 1: Update CentOS
The first step in setting up Nginx on CentOS is to update the system. This ensures that you have the latest security patches and updates installed. To update CentOS, run the following command:
| Command: | sudo yum update |
This command will update all packages and dependencies on your system. Depending on the number of packages that need to be updated, this may take some time.
Step 2: Install Nginx on CentOS
The next step is to install Nginx on CentOS. To do this, run the following command:
| Command: | sudo yum install nginx |
This command will install Nginx and all of its dependencies. Once the installation is complete, you can start Nginx by running the following command:
| Command: | sudo systemctl start nginx |
Step 3: Configure Nginx
By default, Nginx is configured to serve files from the /usr/share/nginx/html directory. To change this, you need to edit the Nginx configuration file. The configuration file is located at /etc/nginx/nginx.conf.
Before you make any changes to the configuration file, it’s a good idea to create a backup. You can do this by running the following command:
| Command: | sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak |
Once you have created a backup, you can edit the configuration file using your preferred text editor. In this example, we’ll use the nano text editor:
| Command: | sudo nano /etc/nginx/nginx.conf |
Within the configuration file, you can find the server block. This is where you can configure the Nginx server. Here’s an example:
server {listen80;server_nameexample.com;root/var/www/example.com;indexindex.html;location / {try_files $uri $uri/ /index.html;}error_page404/404.html;location = /404.html {internal;}error_page500 502 503 504/50x.html;location = /50x.html {internal;}}In this example, we have configured the server to listen on port 80 for the domain example.com. We have also specified the root directory as /var/www/example.com and set the index file to index.html.
Once you have made your changes, save and exit the configuration file.
Step 4: Test Nginx
Now that Nginx is installed and configured, it’s time to test it. To test Nginx, open a web browser and navigate to your server’s IP address. You should see the default Nginx welcome page.
