To upgrade CentOS 6 to version 6.5, follow these steps:
- Backup your data: Before proceeding with the upgrade, it’s always a good idea to backup your data. This way, you can restore your system if something goes wrong during the upgrade process.
- Update existing packages: Before upgrading the CentOS version, you should update all existing packages to their latest version. Run the following command in your terminal:
yum update
- Verify that your system is supported: The upgrade process is supported only for systems that are running CentOS 6.0 or later. You can check your version using the following command:
cat /etc/redhat-release
- Upgrade the operating system: The recommended way to upgrade CentOS is to use the “yum” package manager. This process will upgrade all system packages and the kernel to the latest version. To upgrade your system, run the following command in your terminal:
yum upgrade
- Reboot the system: After the upgrade process is complete, you should reboot your system to apply the changes. Run the following command in your terminal:
reboot
- Verify the new version: After rebooting, verify that the upgrade was successful by checking the version number. Run the following command in your terminal:
cat /etc/redhat-release
This should display the upgraded version number, which should be 6.5. Note that the upgrade process can take some time, depending on the speed of your system and the number of packages that need to be updated.
