1.下载安装包（这里是32位的）：
MySQL-client-5.6.13-1.rhel5.i386.rpm
MySQL-server-5.6.13-1.rhel5.i386.rpm
2.安装
rpm -ivh MySQL-server-5.6.13-1.rhel5.i386rpm -ivh MySQL-client-5.6.13-1.rhel5.i386
3.重启
4.netstate -ntl 查看3306端口是否启动，启动则正常。
5.
mysqladmin -u root password '123456';mysql -u root -p123456
如果进入，即出现mysql>表示安装登陆成功!
但是我第五步总会出错，错误信息是
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
解决办法是：
/etc/init.d/mysql stopmysqld_safe --user=mysql --skip-grant-tables --skip-networking &mysql -u root mysqlmysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';mysql> FLUSH PRIVILEGES;mysql> quit /etc/init.d/mysql restartmysql -u root -pnewpassword
