centos安装mysql5.6

一、首先下载mysql5.6所需安装包， 采用rpm方式进行安装，所以下载以下载以下安装包

MySQL-client-5.6.15-1.el6.x86_64.rpm

MySQL-devel-5.6.15-1.el6.x86_64.rpm

MySQL-server-5.6.15-1.el6.x86_64.rpm

如系统可以联网，可采用以下方式下载，如不能上网可根据以下地址提前下载。

wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-client-5.6.15-1.el6.x86_64.rpm

  

wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-devel-5.6.15-1.el6.x86_64.rpm

 

wget http://cdn.mysql.com/archives/mysql-5.6/MySQL-server-5.6.15-1.el6.x86_64.rpm

 

 二、安装mysql

2.1 检查系统是否已安装mysql

执行以下命令查看系统中是否安装mysql

rpm -qa|grep mysql

 我的系统执行后结果如下：

[[email protected] tmp]# rpm -qa|grep mysql
mysql-libs-5.1.61-4.el6.x86_64

 以上结果显示安装了mysql-libs 且版本为5.1.61，此时必须删除该包，否则安装时会报有冲突，如下所示

MySQL-server-5.6.15-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64

 删除mysql相应的包：

yum -y remove mysql*

 2.2安装mysql

依次执行以下命令进行安装

rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm

 

rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm

 

rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm

 执行结果如下所示：

[[email protected] tmp]# rpm -ivh MySQL-server-5.6.15-1.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!

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
