libmysqlclient.so.15: cannot open shared object file: No such file or directory

问题

All Rails applications are working just fine until today. I am not sure if someone changes the settings on this machine. However does anyone know what could be the fix for this?

Details:

1. Centos 5.5
2. Apache
3. Passenger
4. Rails 3.0.x
5. MySql 5.0.77

Okay this saves the day.

wget -O /usr/lib64/libmysqlclient.so.15 http://files.directadmin.com/services/es_5.0_64/libmysqlclient.so.15
chmod 755 /usr/lib64/libmysqlclient.so.15
ldconfig

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
