The data can only be decrypted by using a unique private key located on the host server. This high level of encryption prevents unauthorized attempts to access the information. Note: Trusted CAs do not verify self-signed certificates. Users cannot use it to validate the identity of their server automatically. It uses the certbot software tool to administer certificates automatically.
Certbot is a highly automated tool. You should first read our tutorial on how to install Apache on CentOS 7 if you need assistance with configuring your firewall and virtual hosts.
Use the command terminal to install the EPEL repository and yum-utils :. Once the installation runs its course, you can start the process to obtain a certificate by entering:. The client asks you to provide an email address and to read and accept the Terms of Services. Certbot then lists the domains available on your server. Once you have made your choices, the message on the terminal confirms that you have enabled encryption for your domain. The certbot renew command checks the installed certificates and tries to renew them if they are less than 30 days away from expiration.
To automate this process, create a cron job to execute the command periodically. Use your preferred text editor to define how often to execute the renew command:. Our detailed guide on how to generate a certificate signing request CSR with OpenSSL is an excellent resource if you need assistance with this process.
You can now install the certificate on your CentOS 7 server. Aftr you have successfully certified the domain and placed the key files on the server, the next step will be to configure the virtual hosts to display the certificate. Test your Apache configuration before restarting. Make sure that the syntax is correct by typing:. A self-signed certificate is useful for testing, in development environments, and on an intranet.
Proceed to configure the virtual host to display the new certificate. To make sure that the syntax is correct, type:. Ask Question. Asked 10 years, 10 months ago. Active 10 months ago.
