| $ cp -a /etc/httpd /etc/httpd_backup |
This command creates a copy of your Apache configuration files in a backup directory. You can restore your Apache configuration files if anything goes wrong during the update.
Step 3: Update Your Operating System
Updating your operating system is necessary before updating Apache. You can use the command below to update your operating system:
