Logging into the linux server, we can use the command line to update the SSL certificate. As technology advances and the amount of data exchanged increases, the need for increased security becomes more and more important. Through this article we will explain how SSL can make the Linux server more secure, how to upgrade SSL on Linux and what benefits it brings us.
SSL (Secure Socket Layer) is a protocol used in computer communication networks that provides secure communication channels to allow the sending and receiving of data. SSL is the most widely used security protocol on the Internet today, and Linux has the ability to upgrade SSL. It is important to upgrade SSL because the data that is exchanged between servers and users must be secure enough to protect against malicious behavior and hackers.
Udating SSL on Linux can be done by first installing the OpenSSL package. This can be done with the command:
# yum install openssl
Once the package is installed, it is important to generate a new SSL certificate and key. This is done by running the OpenSSL command with the following arguments:
# openssl req -newkey rsa:2048 -nodes -keyout my.key -x509 -days 365 -out my.crt
The new SSL certificate and key will now be generated and stored in the current directory. Once completed, the new SSL certificate and key can be activated by running the following command:
# mv my.crt /etc/ssl/certs/
# mv my.key /etc/ssl/keys/
The last step is to edit the Apache configuration file, located at /etc/apache2/apache2.conf. This file must be updated with the new SSL certificate and key, as well as any additional configuration settings. Once this is complete, Apache can be restarted with the command:
# service apache2 restart
By updating SSL on Linux, users can be sure that all data being exchanged between their server and the end user is secure. In addition, the encryption protocols used for SSL are constantly updated to ensure the highest level of security and privacy. This is an important step for any server administrator, and can help improve the overall security of the system.
