一、下載並解壓
$ wget http://cdn.mysql.com/Downloads/MySQL-5.5/MySQL-5.5.42-1.el6.x86_64.rpm-bundle.tar
解壓後得到以下幾個檔案：
$ tar -xvf MySQL-5.5.42-1.el6.x86_64.rpm-bundle.tar  
MySQL-shared-5.5.42-1.el6.x86_64.rpm
MySQL-shared-compat-5.5.42-1.el6.x86_64.rpm
MySQL-server-5.5.42-1.el6.x86_64.rpm
MySQL-devel-5.5.42-1.el6.x86_64.rpm
MySQL-test-5.5.42-1.el6.x86_64.rpm
MySQL-client-5.5.42-1.el6.x86_64.rpm
MySQL-embedded-5.5.42-1.el6.x86_64.rpm

二、安裝
1、安裝server
（1）# rpm -ivh MySQL-server-5.5.42-1.el6.x86_64.rpm

（2）若出現衝突錯誤，則是由於linux可能內建了mysql的庫，需要先將之刪除
# rpm -e mysql-libs.x86_64 --nodeps

2、安裝client
# rpm -ivh MySQL-client-5.5.42-1.el6.x86_64.rpm

三、關於設定檔
# ls *.cnf
my-huge.cnf  my-innodb-heavy-4G.cnf  my-large.cnf  my-medium.cnf  my-small.cnf
# pwd
/usr/share/mysql
使用rpm方法進行安裝時，設定檔放在/usr/share/mysql中，可根據需要放到其它地方。

四、啟動及關閉
1、方式一：命令列方式
# mysqld_safe &
# mysqladmin -uroot shutdown

2、方式二：服務方式
# service mysql start
# service mysql stop
# service mysql restart

3、串連資料庫開始使用
# mysql -u root -p
