ubuntu12.04下 rails 安装mysql

1.安装mysql
sudo apt-get install mysql-server

2.如果此时马上bundle，可能会报如下错误：
ERROR: Failed to build gem native extension
。。。
。。。。
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details
或者
An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

总之，错误连连
3. 解决方法：安装2个lib
sudo apt-get install libmysql-ruby libmysqlclient-dev

4.bundle， 成功！ 楼主笑了！
游客，你笑了么~
