Comment 1 for bug 1291249

@Rene,

If you built php-mysql against Percona-Server-Shared-55, then you will need to rebuild against Percona-Server-Shared-55 again (with Percona-Server-devel-55 installed for mysql_config).

Otherwise, the php you are using, which repo is it from? The php from CentOS6 repo is still linked against libmysqlclient.so.16. http://pkgs.org/centos-6/centos-i386/php-mysql-5.3.3-26.el6.i686.rpm.html, which is provided by mysql-libs and Percona-Server-shared-51 package.

If you are using php from other repo (linked against libmysqlclient.so.18) then you will need to use mysql-libs from that repo.

The reason such a symlink doesn't exist is that we didn't want conflict with upstream libmysqlclient.so.{16..18.1} libraries. (and thus be compatible with them).

mysql-libs-5.5.36 is available otherwise from other repos as well - http://pkgs.org/search/?keyword=mysql-libs (atomic for instance has it)
