Hi, First of all i am sorry to post new post here again as i see this is right place to post for installation errors. I am new to percona, till now I have worked on mysql. Just learned about percona two days back and so thought of giving a try to platform. So i tired in my one of the VPS which is on servermania on openVZ. Details of Installation is as below: OS: Centos 6.5 x64 RAM: 4GB I have not installed any thing prior to percona installation. It is clean fresh OS install. Just did upate through yum update. And followed below installation instruction page for percona installation. “[Percona legacy documentation](http://www.percona.com/doc/percona-server/5.6/installation.html)” Repository get installed without any issue. Start installation with command “yum install Percona-Server-client-56 Percona-Server-server-56” as per the instruction guide i get below output for installation process. =========================================================== [root@domainmy ~]# yum install Percona-Server-client-56 Percona-Server-server-56 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile - base: [mirror.kentdigital.net](http://mirror.kentdigital.net) - extras: [mirror.solarvps.com](http://mirror.solarvps.com) - updates: [distro.ibiblio.org](http://distro.ibiblio.org) Setting up Install Process Resolving Dependencies /… …/ Dependencies Resolved # ================================================================================== Package Arch Version Repository Size Installing: Percona-Server-client-56 x86\_64 5.6.20-rel68.0.el6 percona-release-x86\_64 6.4 M Percona-Server-server-56 x86\_64 5.6.20-rel68.0.el6 percona-release-x86\_64 19 M Installing for dependencies: Percona-Server-shared-56 x86\_64 5.6.20-rel68.0.el6 percona-release-x86\_64 720 k libaio x86\_64 0.3.107-10.el6 base 21 k perl x86\_64 4:5.10.1-136.el6 base 10 M perl-Module-Pluggable x86\_64 1:3.90-136.el6 base 40 k perl-Pod-Escapes x86\_64 1:1.04-136.el6 base 32 k perl-Pod-Simple x86\_64 1:3.13-136.el6 base 212 k perl-libs x86\_64 4:5.10.1-136.el6 base 578 k perl-version x86\_64 3:0.77-136.el6 base 51 k # Transaction Summary Install 10 Package(s) ## Total download size: 38 M Installed size: 158 M Is this ok [y/N]: y Downloading Packages: /… …/ (8/10): perl-Pod-Simple-3.13-136.el6.x86\_64.rpm | 212 kB 00:00 (9/10): perl-libs-5.10.1-136.el6.x86\_64.rpm | 578 kB 00:00 (10/10): perl-version-0.77-136.el6.x86\_64.rpm | 51 kB 00:00 Total 15 MB/s | 38 MB 00:02 warning: rpmts\_HdrFromFdno: Header V4 DSA/SHA1 Signature, key ID cd2efd2a: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Percona Importing GPG key 0xCD2EFD2A: /… …/ Is this ok [y/N]: y /… …/ Running Transaction Installing : Percona-Server-shared-56-5.6.20-rel68.0.el6.x86\_64 1/10 Installing : 1: perl-Pod-Escapes-1.04-136.el6.x86\_64 2/10 Installing : 4: perl-libs-5.10.1-136.el6.x86\_64 3/10 Installing : 1: perl-Pod-Simple-3.13-136.el6.x86\_64 4/10 Installing : 3: perl-version-0.77-136.el6.x86\_64 5/10 Installing : 1: perl-Module-Pluggable-3.90-136.el6.x86\_64 6/10 Installing : 4: perl-5.10.1-136.el6.x86\_64 7/10 Installing : Percona-Server-client-56-5.6.20-rel68.0.el6.x86\_64 8/10 Installing : libaio-0.3.107-10.el6.x86\_64 9/10 Installing : Percona-Server-server-56-5.6.20-rel68.0.el6.x86\_64 10/10 2014-09-29 01:47:27 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.
