What is Rocky Linux?<\/h2>\n\n\n\n
Rocky Linux is an open-source operating system and one of the strongest replacement candidates for CentOS 8. It is a 100% binary-compatible release using the Red Hat Enterprise Linux (RHEL). Let us see how to migrate CentOS 8 Linux live server to Rocky Linux 8 using a shell script provided by the Rocky Linux project.<\/p>\n\n\n\n
Step 1 \u2013 Backup CentOS 8<\/h2>\n\n\n\n
I started the migration process with backup. I do have nightly backups, but before upgrading, I made a snapshot to revert back when something goes wrong. In other words, keep verified backups.<\/p>\n\n\n\n
Step 2 \u2013 Installing all updates on CentOS 8<\/h2>\n\n\n\n
Then I log in using the ssh command: ssh user@cyburdial-php8-app1<\/code><\/p>\n\n\n\n
Now, all we have to do is use the dnf command to apply all pending updates: sudo dnf update<\/code><\/p>\n\n\n\n
Finally, reboot the Linux box using the shutdown command or reboot command: sudo reboot<\/code><\/p>\n\n\n\n
Let us verify CentOS Linux 8 version using the cat command or more command\/less command: more \/etc\/centos-release<\/code> <\/p>\n\n\n\n
RockyLinux<\/figcaption><\/figure><\/div>\n\n\n\n
Step 3 \u2013 Installing git client on CentOS 8<\/h2>\n\n\n\n
We need git to install the migration script. Is git installed on the server? Let us find out. Execute the\u00a0type command: type -a git<\/code><\/p>\n\n\n\n
Let us search for the git package, Execute: dnf list git dnf search git dnf info git<\/code><\/p>\n\n\n\n
Now, install git on your server with the help of the dnf utility, Execute: sudo dnf install git type -a git<\/code> <\/p>\n\n\n\n
Clone the repo to install migration tool called rocky-tool<\/h3>\n\n\n\n
Finally, we need to clone the rocky-tools repo with the help of the git command: cd \/tmp\/ git clone https:\/\/github.com\/rocky-linux\/rocky-tools.git<\/code> Getting ready for Rocky Linux migration<\/p>\n\n\n\n
<\/p>\n\n\n\n
Step 4 \u2013 Migrating from CentOS 8 to Rocky Linux<\/h2>\n\n\n\n
Change the directory using cd command where rocky-tools cloned: cd \/tmp\/rocky-tools\/migrate2rocky<\/kbd><\/li>
Set up executable permissions using the chmod command: chmod -v +x migrate2rocky.sh<\/kbd><\/li>
Start the migration from CentOS 8 to Rocky Linux by typing the migrate2rocky.sh command: .\/migrate2rocky.sh -r<\/kbd> <\/li>
Follow on-screen instructions and wait for some time to finish the migration job. At the end you should see:Done, please reboot your system. A log of this installation can be found at \/var\/log\/migrate2rocky.log<\/li><\/ol>\n","protected":false},"excerpt":{"rendered":"
