需要下载三个rpm软件包：

MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
MySQL-server-5.6.21-1.rhel5.x86_64.rpm

下载地址下载地址引用处：

http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm

安装

rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm
可能需要安装：libaio
yum install -y libaio

修改配置文件位置。

[root@linuxidc tools]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

初始化MySQL及修改MySQL默认的root密码。

/usr/bin/mysql_install_db
ps -ef | grep mysql
netstat -anpt | grep 3306
more /root/.mysql_secret

mysql -uroot -pF6K3v_xggFoLQeiN
mysql> SET PASSWORD = PASSWORD(‘mima’);

[root@linuxidc tools]# mysql -uroot -pmima

mysql>

设置MySQL服务开机自启动。

[root@linuxidc tools]# chkconfig mysql on
[root@linuxidc tools]# chkconfig mysql –list

安装过程的错误的解决

1、重点在centos6中使用mysql管理他的服务而不是mysqld
2、错误描述：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)这个问题属于mysql的服务没有开启。

解决方法：

systemctl start mysql（centos7）service mysql start(centos6)

3、错误描述：

file /usr/share/mysql/charsets/swe7.xml from install of MySQL-server-5.6.21-1.rhel5.x86_64 conflicts with file from package mariadb-libs-1:5.5.44-2.el7.centos.x86_64

解决办法：

 yum remove mysql-libs

远程连接

1、mysql中执行

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '密码' WITH GRANT OPTION;

这样在物理机的外面就可以访问vm中的linux了。
