查看操作系统相关信息。
[root@bj_db1 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@bj_db1 ~]# uname -a
Linux bj_db1 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
2.创建需要下载rpm软件包的目录。
[root@bj_db1 ~]# mkdir -p /taokey/tools
3.查看下是否有系统自带mysql的rpm包，如果有，需要删除自带的旧rpm包。
[root@bj_db1 ~]# rpm -qa | grep mysqlmysql-libs-5.1.71-1.el6.x86_64[root@bj_db1 ~]# yum -y remove mysql-libs-5.1*[root@bj_db1 ~]# rpm -qa | grep mysql[root@bj_db1 ~]#
4.在MySQL官网下载安装MySQL-5.6.21所需的rpm软件包。
需要下载三个rpm软件包：
MySQL-client-5.6.21-1.rhel5.x86_64.rpm MySQL-devel-5.6.21-1.rhel5.x86_64.rpm MySQL-server-5.6.21-1.rhel5.x86_64.rpm[root@bj_db1 ~]# cd /taokey/tools/[root@bj_db1 tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm[root@bj_db1 tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm[root@bj_db1 tools]# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm
5.下载完之后，安装三个rpm软件包。
[root@bj_db1 tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
error: Failed dependencies:
libaio.so.1()(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
安装MySQL-server报错，原因是没有安装libaio，系统缺少libaio.so此软件包，下边yum安装一下libaio.so软件包。
[root@bj_db1 tools]# yum install -y libaio[root@bj_db1 tools]# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm[root@bj_db1 tools]# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm Preparing... ########################################### [100%] 1:MySQL-client ########################################### [100%][root@bj_db1 tools]# rpm -ivh MySQL-devel-5.6.21-1.rhel5.x86_64.rpm Preparing... ########################################### [100%] 1:MySQL-devel ########################################### [100%]
6.修改配置文件位置。
[root@bj_db1 tools]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
7.初始化MySQL及修改MySQL默认的root密码。
[root@bj_db1 tools]# /usr/bin/mysql_install_db[root@bj_db1 tools]# /etc/init.d/mysql start[root@bj_db1 tools]# ps -ef | grep mysqlroot 2188 1 0 14:48 pts/1 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/bj_db1.pidmysql 2303 2188 30 14:48 pts/1 00:00:02 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/bj_db1.err --pid-file=/var/lib/mysql/bj_db1.pidroot 2331 1853 0 14:49 pts/1 00:00:00 grep mysql[root@bj_db1 tools]# netstat -anpt | grep 3306tcp 0 0 :::3306 :::* LISTEN 2303/mysqld[root@bj_db1 tools]# more /root/.mysql_secret# The random password set for the root user at Thu Apr 9 14:43:59 2015 (local time): F6K3v_xggFoLQeiN[root@bj_db1 tools]# mysql -uroot -pF6K3v_xggFoLQeiNWarning: Using a password on the command line interface can be insecure.Welcome to the MySQL monitor.

8.设置MySQL服务开机自启动。
[root@bj_db1 tools]# chkconfig mysql on[root@bj_db1 tools]# chkconfig mysql --listmysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off
9.MySQL三中修改账号密码的方法：
1).为特定用户账号设置密码；
SET PASSWORD FOR "username"@"host" = PASSWORD("123.com");
2).直接修改表中内容的方式，修改数据库账号密码；
update user set password=PASSWORD('your_password') WHERE User='root' and host='hostname or ip';
通常修改不会立即生效，需要执行flush
3).mysqladmin修改root密码
mysqladmin -u root -h127.0.0.1 -p password 'new_password'
回车之后要求输入旧密码，旧密码为空直接回车即可。
到此为止，使用RPM安装MySQL5.6版本数据库安装完毕，谢谢大家。
