You can try to find the right package by the following command:
$ sudo yum whatprovides libmysqlclient.so.15
libmysqlclient15-5.0.95-5.w5.i386
libmysqlclient15-devel-5.0.95-5.w5.i386
cpanel-mysql-libs-5.0.96-1.cp1136.i386 : The shared libraries required for MySQL clients
then:
$ sudo yum reinstall WHATEVER_THE_PACKAGE_NAME_IS
You may double check the package name by doing yum search package_name
.
If not found, you may try to fix your yum repositories e.g. by configuring Webtatic Yum Repository.
To set up the repository, install the webtatic-release RPM:
Webtatic EL6 for CentOS/RHEL 6:
rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
Webtatic EL5.1 for CentOS/RHEL 5:
rpm -Uvh http://repo.webtatic.com/yum/el5/latest.rpm
Webtatic 5 for CentOS/RHEL 5:
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm
and repeat the search/reinstall process again.
If you're running cPanel, you may try to run the following script:
/scripts/check_cpanel_rpms --fix
If won't help, remove the broken package e.g. rpm -e cpanel-mysql-5.0.96-1.cp1136
and run the check command again.
If still doesn't work, another thing could be to recompile your Apache (only if your LAMP is broken) by:
/scripts/easyapache
