Ubuntu mysql 换为 Percona server

Percona apt Repository

Debian and Ubuntu packages from Percona are signed with a key. Before using the repository, you should add the key toapt. To do that, run the following commands:

$ gpg --keyserver  hkp://keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A
... [some output removed] ...
gpg:               imported: 1

$ gpg -a --export CD2EFD2A | sudo apt-key add -

Add this to /etc/apt/sources.list, replacing VERSION with the name of your distribution:

deb http://repo.percona.com/apt VERSION main
deb-src http://repo.percona.com/apt VERSION main

Remember to update the local cache:

# apt-get update

After that you can install the server and client packages

# apt-get install percona-server-server-5.5 percona-server-client-5.5

在有mysql 的ubuntu 上只需要 apt-get autoremove mysql客户端 和 服务器 就可以 执行上面的命令啦
