The procedure for raising the CentOS version 6.5 to version 7.0
We start with the installation of Redhat upgrade tool:
We add a new repository since redhat-upgrade-tool is not available in the standard repositories.
# Vi /etc/yum.repos.d/upgrade.repo
Add the following entry:
[upgrade] name = upgrade baseurl = http: //dev.centos.org/centos/6/upg/x86_64/
enabled = 1
gpgcheck = 1
The second stage of installing these packages
# Yum install preupgrade es-assistant-contents redhat-upgrade-tool preupgrade-assistant
Enter the command preupg to diagnose any problems that arise during the renovation
# preupg
or you can enter a command that will show errors
# Preupg --riskcheck --verbose
We import the GPG key needed:
# Rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7
Charge to initiate the update package:
# Centos-upgrade-tool-cli --network 7 --instrepo = http: //mirror.centos.org/centos/7/os/x86_64/
If at this point we find the problems wymuśmy power To assume:
# Centos-upgrade-tool-cli --network 7 --force --instrepo = http: //mirror.centos.org/centos/7/os/x86_64/
rpm transaction 100%
setting up the system for upgrade Finished. Reboot to start the upgrade.
At the end we reboot the system during boot is updated.
#reboot
If during testing preupg command will show the errors could mean that the execution of the upgrade is virtually impossible.
Errors found during the installation that prevent the upgrade:
