PXC8 tarball glibc version suitable for RHEL8?

MySQL & MariaDB Percona XtraDB Cluster 8.x

Hi Folks,

We make use of the PXC8 tarball versions (to allow non-root install etc). For RHEL8 servers we’ve initially been deploying the tarball based around glibc2.17 i.e. downloaded from:

https://downloads.percona.com/downloads/Percona-XtraDB-Cluster-80/Percona-XtraDB-Cluster-8.0.32/binary/tarball/Percona-XtraDB-Cluster_8.0.32-24.2_Linux.x86_64.glibc2.17.tar.gz

Whilst this does work we’ve noticed it contains old 1.0.2k ssl libs which is a concern from a vulnerability scan perspective e.g: OpenSSL 1.0.2 < 1.0.2za Vulnerability<!-- --> | Tenable®

Looking at the Percona download site (for PXC 8.0.32 by example) there seems to be 3 different glibc versions available:

  • Percona-XtraDB-Cluster_8.0.32-24.2_Linux.x86_64.glibc2.17.tar.gz
  • Percona-XtraDB-Cluster_8.0.32-24.2_Linux.x86_64.glibc2.34.tar.gz
  • Percona-XtraDB-Cluster_8.0.32-24.2_Linux.x86_64.glibc2.35.tar.gz

My understanding of glibc versions for RHEL is:

  • RHEL7 - glibc2.17
  • RHEL8 - glibc2.28
  • RHEL9 - glibc2.34

…and this is quite strict I believe.

Is there a reason therefore that glibc2.28 (i.e RHEL8) versions of these tarballs do not exist?

many thanks,

Neil

Bump.

Anyone have any ideas on this one?

thanks,

Neil

Hey @Neil_Billett .
Yes each OS has it’s own glibc version. But glibc has a good backward compatibility. As we create generic tarballs we use the oldest possible glibc version (we support centos7, ol8 and ol9 so it is centos7) and create tarball based on this version

Hi @Neil_Billett

I noticed you have also asked a similar question with regards to Percona XtraBackup in this thread: https://forums.percona.com/t/xtrabackup-8-tarball-glibc-version-suitable-for-rhel8/28182 I have provided additional response there. Just FYI.

Cheers,
Bartek.
