*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
Provided configuration options:
–with-opt-dir

所以得先 remove MySQL 然後再重新安裝 MySQL 跟 MySQL Development Lib

yum remove mysql
yum install mysql
yum install mysql-devel

要在 CentOS 安裝 Rails Gem，那就

gem i rails -y 即可。

gem install mysql -- --with-mysql-include=/usr/include/mysql/mysql --with-mysql-lib=/usr/lib/mysql/
