linux安装mysql的方法
1、上传并解压mysql安装包 MySQL-5.6.23-1.rhel5.i386.rpm-bundle.tar
[hadoop@mdw mysql]$ cp /mnt/cdrom/MySQL-5.6.23-1.rhel5.i386.rpm-bundle.tar .
[hadoop@mdw mysql]$ tar xf MySQL-5.6.23-1.rhel5.i386.rpm-bundle.tar
2、使用root账户安装mysql
[root@mdw mysql]# rpm -ivh MySQL-server-5.6.23-1.rhel5.i386.rpm
如果报以下错误，解决方法参考linux安装MySQL 5.6.10包冲突问题导致安装失败的问题

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
[root@mdw mysql]#
mysql的server安装完成后，会随机生成一个密码，密码放在/root/.mysql_secret文件中，如上面红色部分，查看该文件：
[root@mdw mysql]# cat /root/.mysql_secret
# The random password set for the root user at Sat Jun 6 06:42:28 2015 (local time): ql2NNQ3RnBiuz3aE
3、安装mysql的client和mysql devel
[root@mdw mysql]# rpm -ivh MySQL-client-5.6.23-1.rhel5.i386.rpm

4、启动mysql服务
[root@mdw mysql]# service mysql start
Starting MySQL.. SUCCESS!
5、登录mysql server并修改root密码
[root@mdw mysql]# mysql -uroot -p
Enter password: 【输入刚才生成的密码】
