在RedHat 6.3下安装MySQL-server-5.6.13-1.el6.x86_64.rpm
首先下载下面三个文件：
MySQL-client-5.6.13-1.el6.x86_64.rpm
MySQL-devel-5.6.13-1.el6.x86_64.rpm
MySQL-server-5.6.13-1.el6.x86_64.rpm
然后使用root账号登陆，进行安装：
1. 安装server、devel、client：1. 安装server、devel、client：
rpm -ivh --replacefiles MySQL-s*.rpm
rpm -ivh --replacefiles MySQL-d*.rpm
rpm -ivh --replacefiles MySQL-c*.rpm
[root@localhost download]# rpm -ivh --replacefiles MySQL-server-5.6.13-1.el6.x86_64.rpm

要移除安装可以使用 rpm -e MySQL-server 、 rpm -e MySQL-devel、MySQL-client即可；
2. 初始化数据库：
/usr/bin/mysql_install_db
3. 启动mysql服务：
service mysql start
使用命令ps -ef | grep mysql 查看mysql进程：
[root@localhost ~]# ps -ef | grep mysql
root 26047 1 0 18:14 pts/12 00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/localhost.localdomain.pid
mysql 26227 26047 0 18:14 pts/12 00:00:01 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/log/mysqld.log --pid-file=/var/lib/mysql/localhost.localdomain.pid --socket=/var/lib/mysql/mysql.sock
root 26545 24726 0 18:27 pts/8 00:00:00 grep mysql
4.第一次登陆设置root密码：
首先查看 cat /root/.mysql_secret
root@localhost ~]# cat /root/.mysql_secret
# The random password set for the root user at Fri Aug 30 15:57:18 2013 (local time): fMYcarvB
然后命令行：mysql -u root -p ，然后输入上面的密码即可：
[root@localhost ~]# mysql -u root -p
Enter password:

注意：
MySql5.6操作时报错：You must SET PASSWORD before executing this statement解决
mysql> SET PASSWORD = PASSWORD('123456');
Query OK, 0 rows affected (0.03 sec)
mysql> create database roger;
Query OK, 1 row affected (0.00 sec)
也就是用mysql> SET PASSWORD = PASSWORD('123456');这句话重新设置一次密码！
设置root密码：
mysql> use mysql
Database changed
mysql> update user set password=password('root') where user='root';
Query OK, 0 rows affected (0.15 sec)
Rows matched: 5 Changed: 0 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
退出，重新登陆即可使用新的密码登陆；
5. 设置远程登陆：
使用root登陆到mysql后
mysql> update user set host='%' where user='root';
ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'
mysql> select host,user from user;
+-----------------------+------+
| host | user |
+-----------------------+------+
| % | root |
| 127.0.0.1 | root |
| 192.168.128.142 | root |
| ::1 | root |
| localhost.localdomain | root |
+-----------------------+------+
5 rows in set (0.00 sec)
然后：
mysql> grant all privileges on *.* to 'root'@'%' with grant option;
Query OK, 0 rows affected (0.08 sec)
mysql> exit
Bye
[root@localhost ~]# service mysql restart
Shutting down MySQL.. SUCCESS!
Starting MySQL.. SUCCESS!
重启mysql即可远程登陆。
