php-mysql from remi does not work with Percona-Server

On Centos 6.5 regular PHP packages work:

[root@vagrant-centos65 vagrant]# php -v

Percona-Server-shared-56 = 5.6.17-rel66.0.el6
Percona-Server-shared-56(x86-64) = 5.6.17-rel66.0.el6

But when remi repository is installed and try to do a yum update I get the following:

[root@vagrant-centos65 vagrant]# yum update

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

However, if I remove Percona Server 56 and disable Percona repo then run a yum update then install PS 5.6 back then everything works.

I think you also have libmysqlclient.so.18 from remi repo. Usually at /usr/lib64/mysql
But Percona library usually at /usr/lib64

You can check with:
cd /usr/lib64/php/modules
ldd mysql.so

which library uses your php-mysql package ...

@Aleksis

Indeed, I have libmysqlclient.so.18 on /usr/lib64/mysql and libperconaserverclient.so.18 on /usr/lib64

And in my case php-mysql uses libmysqlclient.so.18
[root@vagrant-centos65 modules]# ldd mysql.so | grep mysql
 libmysqlclient.so.18 => /usr/lib64/mysql/libmysqlclient.so.18 (0x00007f3f37a20000)

Why is Percona-Server-shared-56 installed for libmysqlclient.so.18 dependency.
Percona-Server-shared-55 should be installed for it. If it got pulled
automatically, then it is probably due to https://bugs.launchpad.net/percona-server/+bug/1329911

Secondly, even then, symbol versioning looks broken. Any applications which depend
on that or verify it (like postfix) may still complain, as the readelf also
confirms.

Right the same with 55, difference is in --provides :

5.6.17:
[root@centos5-php-test yum.repos.d]# rpm -q Percona-Server-shared-56.x86_64 --provides
libmysqlclient.so.18()(64bit)
libperconaserverclient.so.18()(64bit)
libperconaserverclient.so.18(libperconaserverclient_18)(64bit)
Percona-Server-shared-56 = 5.6.17-rel66.0.el6
Percona-Server-shared-56(x86-64) = 5.6.17-rel66.0.el6

and

5.6.16:
[root@centos5-php-test yum.repos.d]# rpm -q Percona-Server-shared-56-5.6.16-rel64.2.el6.x86_64 --provides
libmysqlclient.so.18()(64bit)
libperconaserverclient.so.18()(64bit)
libperconaserverclient.so.18(libperconaserverclient_18)(64bit)
Percona-Server-shared-56 = 5.6.16-rel64.2.el6
Percona-Server-shared-56(x86-64) = 5.6.16-rel64.2.el6

and

5.6.15
[root@centos5-php-test yum.repos.d]# rpm -q Percona-Server-shared-56.x86_64 --provides
libmysqlclient.so.18()(64bit)
libmysqlclient.so.18(libmysqlclient_16)(64bit)
libmysqlclient.so.18(libmysqlclient_18)(64bit)
libmysqlclient.so.18(libmysqlclient_18_1)(64bit)
mysql-libs
mysql-shared
Percona-Server-shared-56 = 5.6.15-rel63.0.519.rhel6
Percona-Server-shared-56(x86-64) = 5.6.15-rel63.0.519.rhel6

Just a quick note - but installing Percona-XtraDB-Cluster-shared-56-5.6.15-25.5.759.rhel6.x86_64 solves libmysqlclient.so.18 problem.

So all combined it works like this:

Percona-Server-client-55-5.5.38-rel35.2.el6.x86_64
Percona-Server-server-55-5.5.38-rel35.2.el6.x86_64
Percona-Server-shared-compat-5.1.68-rel14.6.551.rhel6.x86_64
Percona-XtraDB-Cluster-shared-56-5.6.15-25.5.759.rhel6.x86_64
Percona-Server-shared-55-5.5.38-rel35.2.el6.x86_64

And then php-mysql from the remi repo works.

I confirm behaviour. Solution given on comment #6 is still working.
