Percona 是否向后兼容 MySQL？ 导轨盒中的 Ruby

Question

I'm starting a Ruby on Rails project and I'm interested in using Percona as my DBMS. I've read that Percona is fully compatible with MySQL tooling

I wonder if I can use Ruby on Rails tooling with Percona (using the MySQL support)?

Answer 1

I recently switched to Percona as well, you just need to install the mysql development library they provide, for ubuntu/debian you need to run: sudo apt-get install libmysqlclient-dev

Install mysql/mysql2 gems as normal, no need to specify mysql_config location.

Answer 2

As long as you have the mysql client libraries you should be able to build the mysql gem which is the interface rails (through active record) uses to interact with mysql.

You may have to pass the percona mysql_config when building the gem like so:

gem install mysql -- --with-mysql-config=/usr/local/percona-xtradb/bin/mysql_config

If you are using the mysql2 gem you "shouldn't" need to do this (I think)

Answer 3

I'm on CentOS 5 using Percona 5.5 and was having trouble installing the mysql gem. And as mentioned above, you just need the appropriate percona devel libraries for your system.

Get them here: http://www.percona.com/downloads/Percona-Server-5.5/

If you have Ruby 1.8.5, install the gem with:

gem install mysql --no-ri --no-rdoc -v 2.7  -- --build-flags --with-mysql-config

If you have 1.8.6 or above, use:

gem install mysql --no-ri --no-rdoc -- --build-flags --with-mysql-config

You might be able to omit some of those parameters, but that is what I've found to work well given the different Ruby versions..
