HTTPS configuration and precautions for building a web server on CentOS
With the popularity and development of the Internet, security has become an important aspect in website operation and maintenance. In order to protect users' personal information, it has become a trend to use HTTPS protocol for website encryption. In this article, we will introduce how to set up a web server and configure HTTPS on CentOS, and list some things to pay attention to.
Before you begin, please ensure that you have installed the CentOS operating system and have certain experience in Linux system management and operation and maintenance. In addition, you will need a domain name and SSL certificate. You can purchase a commercial SSL certificate or use Let's Encrypt's free certificate for testing.
First, we need to install Apache as the web server. Use the following command to install:
sudo yum install httpd
After the installation is complete, start Apache and set it to start automatically at boot:
sudo systemctl start httpd sudo systemctl enable httpd
mod_ssl is for Apache A module to support the HTTPS protocol. Use the following command to install:
sudo yum install mod_ssl
After the installation is complete, restart Apache:
sudo systemctl restart httpd
Change your domain name and SSL certificate Place the file in the appropriate location, then edit Apache's configuration file:
sudo vi /etc/httpd/conf.d/ssl.conf
Find and edit the following lines, replacing them with your certificate file path and key file path:
SSLCertificateFile /path/to/your_certificate_file SSLCertificateKeyFile /path/to/your_private_key_file
Save and exit the file. Restart Apache:
sudo systemctl restart httpd
At this point, your website already supports the HTTPS protocol.
In order to increase the security of the website, we can also adjust the SSL protocol and encryption algorithm. Edit the following file:
sudo vi /etc/httpd/conf.d/ssl.conf
Find and edit the following lines, replacing them with a more secure configuration:
SSLProtocol TLSv1.2 SSLHonorCipherOrder on SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
Save and exit the file. Restart Apache:
sudo systemctl restart httpd
When configuring HTTPS, there are some things to pay attention to:
Summary
This article introduces the steps and precautions for building a web server on CentOS and configuring HTTPS. When configuring HTTPS, we need to install Apache and the mod_ssl module, configure the SSL certificate, and adjust the SSL protocol and encryption algorithm. We also remind you of some things you need to pay attention to to increase the security of your website. I hope this article can be helpful to you, and I wish you success in setting up a secure web server!
