libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.0.0-p643/gems/mysql2-0.3.18 for inspection.
Results logged to /usr/local/rvm/gems/ruby-2.0.0-p643/extensions/x86-linux/2.0.0/mysql2-0.3.18/gem_make.out
An error occurred while installing mysql2 (0.3.18) , and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.18'` succeeds before bundling.
it is advised to put mysql-server mysql-client libmysqlclient-dev
but how to do it on cent os? I read somewhere that these libraries are not installed on cent os in principle ....

On CentOS 7:

[[email protected] ~]# rpm -ql mariadb-devel.x86_64 | grep mysql\\.h
/usr/include/mysql/mysql.h
/usr/include/mysql/private/probes_mysql.h
[[email protected] ~]#

So
or something like that (perhaps in version 6 it was somehow different).
