Hi All, I’m trying to get xtradb cluster installed on my new server. At first I notice that the new server which is on RHEL 6 comes with mysql installed. I’ve uninstalled the existing mysql & tried to run the installation for xtradb cluster. However I’m getting this error & I can’t move forward. Any idea how do I find those dependency packages? –\> Finished Dependency ResolutionError: Package: Percona-XtraDB-Cluster-server-57-5.7.29-31.43.1.el6.x86\_64 (percona-release-x86\_64)           Requires: socatError: Package: percona-xtrabackup-24-2.4.20-1.el6.x86\_64 (percona-release-x86\_64)           Requires: libev.so.4()(64bit) You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest ---

Hi @JasonO. You need to enable epel repo in order to install socat and libev. How it can. be done: sudo yum -y install epel-release After this you can install Percona-XtraDB-Cluster. Also please keep in mind thatCentOS-6 will reach End of Life on  **November 30th, 2020**
