CentOS 6.6上安装MySQL 5.6

1、首先第一步是安装好CentOS 6.6

先下载好centos 6.6，然后，在虚拟机中安装好系统。

需要安装vmware tools，由于VMware Tools这个目录中包含了空格，所以要用 \ 来转义空格：

[root@ggg1 Desktop]# cd /media/VMware\ Tools

[root@ggg1 Desktop]# tar -zvxf VMwareTools-9.2.0-799703.tar.gz -C /root/Desktop

安装后，就可以从LInux中复制粘贴。

2、下载MysqL 5.6

MysqL的下载地址是在 网页 http://downloads.MysqL.com/archives/community/ 中，我选择了MysqL 5.6.12版，具体的rpm包是：MysqL-server-5.6.12-2.el6.x86_64.rpm。

通过wget命令来下载，指定的下载地址是：http://dev.MysqL.com/get/Downloads/mysql-5.6/MysqL-server-5.6.12-2.el6.x86_64.rpm

[root@wc1 Desktop]# wget http://dev.MysqL.com/get/Downloads/mysql-5.6/MysqL-server-5.6.12-2.el6.x86_64.rpm

运行如下命令来安装，但是并没有安装，显示有冲突，从字面的意思看出，大致上是我要安装的rpm包，和之前的MysqL-libs-5.1.73-3.el6_5.x86_64 有冲突：

[root@wc1 Desktop]# rpm -ivh MysqL-server-5.6.12-2.el6.x86_64.rpm

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.

Please report any problems with the /usr/bin/MysqLbug script!

The latest information about MysqL is available on the web at

  http://www.MysqL.com

Support MysqL by buying support/licenses at http://shop.MysqL.com

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@wc1 Desktop]# 

从上面的安装日志中，能够看到很多有用的信息，比如：

A RANDOM passworD HAS BEEN SET FOR THE MysqL root USER !
you will find that password in '/root/.MysqL_secret'.

至此，安装成功

4、下载并安装MysqL 客户端

安装好了MysqL之后，我们需要连接到MysqL，但是由于MysqL-server并不包含客户端，所以还要下载客户端。

先下载：

[root@wc1 Desktop]# wget http://dev.MysqL.com/get/Downloads/mysql-5.6/MysqL-client-5.6.12-2.el6.x86_64.rpm
--2016-08-16 13:20:48--  http://dev.MysqL.com/get/Downloads/mysql-5.6/MysqL-client-5.6.12-2.el6.x86_64.rpm

   1:MysqL-client           ########################################### [100%]

5、启动MysqL

[root@wc1 Desktop]# service MysqL start
StarTing MysqL....                                         [  OK  ]

[root@wc1 Desktop]# chkconfig --list | grep MysqL
MysqL          	0:off	1:off	2:on	3:on	4:on	5:on	6:off

如果没有设置，可以通过如下命令来设置：

[root@wc1 Desktop]# chkconfig MysqL on

要登录MysqL，就得有密码，而密码就在这个文件里'/root/.MysqL_secret'.

于是找到这个文件，这里ls的参数a只指显示所有隐藏的文件，包含以点开头的，而l参数表示显示详细列表：

[root@wc1 ~]# ls -al | grep 'secret'
-rw-------.  1 root root    96 Aug 16 11:46 .MysqL_secret
[root@wc1 ~]# cat .MysqL_secret
# The random password set for the root user at Tue Aug 16 11:46:41 2016 (local timE): 6g2niot5

[root@wc1 ~]# MysqL -uroot -p
