Setting up Apache Server on Centos
Now that we’ve covered the basics, let’s get started with setting up Apache Server on Centos.
Step 1: Updating your System
Before we begin, it’s essential to make sure your system is up to date. To do this, log in to your server as the root user or a user with sudo privileges and run the following command:
sudo yum update
This command will update all packages and dependencies on your system to their latest version.
Step 2: Installing Apache Server
Once your system is up to date, we can install Apache Server by running the following command:
sudo yum install httpd
This command will install Apache Server on your system.
Step 3: Starting Apache Server
After installing Apache Server, you can start it by executing the following command:
sudo systemctl start httpd
This command will start Apache Server on your system.
Step 4: Enabling Apache Server
To enable Apache Server to start automatically when you boot your system, run the following command:
sudo systemctl enable httpd
This command will enable Apache Server to start automatically on system boot.
Step 5: Testing Apache Server
To test if Apache Server is working correctly, open your web browser and visit http://localhost. If Apache Server is running correctly, you will see a default page that says “Apache 2 Test Page.”
Step 6: Configuring Apache Server
By default, Apache Server is configured to use the /var/www/html directory as the document root directory. You may need to modify this configuration to serve your website or application.
To modify the configuration, you’ll need to edit the Apache Server configuration file located at /etc/httpd/conf/httpd.conf.
