在centos 7操作系统环境下安装mysql

在centos操作系统环境下，安装mysql真是曲折啊，动用了在线安装和离线安装，在线安装前提是有网络连接，但是我在线安装的时候，发现不少问题，总是缺少相应的包，后来采用离线安装

下载mysql，在官方下载，因为在官方下载最靠谱

以下是网址：http://dev.mysql.com/downloads/file.php?id=457682

下完之后，我的mysql名字是MySQL-5.6.25-1.linux_glibc2.5.x86_64.rpm-bundle.tar

无论手动建档还是命令行建档，能解决问题都一样

1. [root@localhost  mysql]# rpm -qa|grep mysql

查看是否有有没有自带的mysql，如果有请卸载

首先解压软件包：利用命令行解压

第一步安装：服务端MySQL-server-5.6.25-1.linux_glibc2.5.x86_64.rpm

 2. [root@localhost  mysql]# rpm -ivh MySQL-server-5.6.25-1.linux_glibc2.5.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 at http://bugs.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.
