Can't install percona-xtradb-cluster

[jasonfe33]

Trying to install percona xtradb cluster 8 on my Oracle Linux 8.4 server.
When trying to run yum install percona-xtradb-cluster I receive.

Last metadata expiration check: 0:54:01 ago on Wed 13 Oct 2021 02:45:31 PM CDT.
All matches were filtered out by modular filtering for argument: percona-xtradb-cluster
Error: Unable to find a match: percona-xtradb-cluster

Repositories look good and ran
sudo dnf install https://repo.percona.com/yum/percona-release-latest.noarch.rpm

which worked fine
then ran

sudo percona-release enable pxc-80

but now I am not able to install the cluster piece. When searching percona it does not show any 8.x versions available for install.

What am I doing wrong? or what needs to be adjusted for this to work?

Hello @jasonfe33,

@jasonfe33

What am I doing wrong? or what needs to be adjusted for this to work?

When you are “enabling” the repo the percona-release script just enables the pxc-80 repo, but doesn’t disables MySQL dnf module, which prevents pxc-80 packages of being searched/installed.
In this case you just need to run the following command before installing percona-xtradb-cluster of 8.0 version:

dnf module disable mysql -y

Also, this is done by the script automatically if you use the setup command:

percona-release setup pxc-80

Along with enabling pxc-80 repo and disabling MySQL dnf module, the setup command also enables supplementary repo which is called tools.

Thank you so much for this. I was trying to install version 5.7 and running

percona-release enable ps-57 release

did not automatically run

dnf module disable mysql -y

I had also run

percona-release setup ps-57
