Why Use CentOS 7?
CentOS 7 is a popular Linux distribution that is widely used for web server hosting. It is an open-source operating system based on the Red Hat Enterprise Linux (RHEL) operating system. CentOS 7 is known for its stability, security, and reliability. It also has a large community of users who actively contribute to its development and maintenance.
Setting Up the Apache Server
Now, let’s get started with setting up the Apache server on your CentOS 7 system. Follow the step-by-step process below:
Step 1: Install Apache
The first step is to install the Apache web server. You can use the yum package manager to install Apache on CentOS 7. Run the following command as root:
Command |
Description |
yum install httpd |
Installs Apache on CentOS 7 using yum |
This command will install Apache on your CentOS 7 system along with its dependencies. You will be prompted to confirm the installation. Press ‘y’ to proceed.
Step 2: Start the Apache Server
Once Apache is installed, you need to start the server. You can use the systemctl command to start, stop, and manage system services on CentOS 7. Run the following command as root:
Command |
Description |
systemctl start httpd |
Starts the Apache web server on CentOS 7 |
This command will start the Apache server on your CentOS 7 system. You can check if the server is running by visiting your server’s public IP address or domain name in a web browser. You should see the Apache default page, which confirms that the server is up and running.
Step 3: Configure Apache to Start Automatically
To ensure that the Apache server starts automatically when you boot your CentOS 7 system, you need to configure it as a system service. You can use the systemctl command to enable Apache as a system service. Run the following command as root:
Command |
Description |
systemctl enable httpd |
Enables Apache as a system service on CentOS 7 |
This command will configure Apache to start automatically when you boot your CentOS 7 system. You can reboot your system to test if Apache starts automatically upon boot.
Step 4: Secure Your Apache Server
Now that you have set up and started the Apache server on your CentOS 7 system, you need to secure it to prevent unauthorized access and hacking attempts. You can use the following tips to secure your Apache server:
Tip 1: Install an SSL Certificate
An SSL certificate provides a secure connection between your server and the client browser. It encrypts data in transit and prevents eavesdropping, data theft, and man-in-the-middle attacks. You can obtain an SSL certificate from a trusted certificate authority (CA) or use a self-signed certificate. To install an SSL certificate on Apache, follow these steps:
- Generate a private key
- Create a certificate signing request (CSR)
- Submit the CSR to a certificate authority (CA)
- Receive the SSL certificate from the CA
- Install the SSL certificate on Apache
Tip 2: Disable Directory Listing
Directory listing allows users to see the contents of a directory on your server. It can expose sensitive files and directories to unauthorized users. You can disable directory listing on Apache by adding the following line to your Apache configuration file:
| Options -Indexes | Disables directory listing on Apache |
Tip 3: Use Strong Passwords
Weak passwords are easy to guess and can allow unauthorized access to your server. You should use strong passwords that are difficult to guess and include a mix of letters, numbers, and special characters. You can use a password manager to generate and store strong passwords.
Tip 4: Keep Your Server Updated
Keeping your server updated with the latest security patches and software updates can prevent vulnerabilities and exploits. You should regularly check for updates and apply them promptly to keep your server secure.
