**1.配置yum源**

*  vim /etc/yum.repos.d/mysql-community.repo

> 输入如下内容：  
> \[mysql-connectors-community\]  
> name=MySQL Connectors Community  
> baseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/6/$basearch/  
> enabled=1  
> gpgcheck=1  
> gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql  
>

> \[mysql-tools-community\]  
> name=MySQL Tools Community  
> baseurl=http://repo.mysql.com/yum/mysql-tools-community/el/6/$basearch/  
> enabled=1  
> gpgcheck=1  
> gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

**2.yum安装**

> **yum list|grep mysql-community**  
> mysql-community-bench.x86\_64               5.6.30-2.el6                 mysql56-community  
> mysql-community-client.i686                5.6.30-2.el6                 mysql56-community

**3.启动mysql**

> service mysqld start  
>

**4.设置root密码**

> /usr/bin/mysqladmin -u root password '××××××'  
>

**5.更改超级用户，删除敏感root账户，授权一般用户**

*  **查看root权限**

>         mysql> show grants for 'root'@'localhost';  
>         +----------------------------------------------------------------------------------------------------------------------------------------+  
>         | Grants for root@localhost                                                                                                              |  
>         +----------------------------------------------------------------------------------------------------------------------------------------+  
>         | GRANT ALL PRIVILEGES ON \*.\* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '\*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' WITH GRANT OPTION |  
>         | GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION                                                                           |  
>         +----------------------------------------------------------------------------------------------------------------------------------------+  
> 
> 
>         2 rows in set (0.00 sec)  
>

*  **授予超级用户和root相同权限**

> grant all privileges on \*.\* to '超级用户'@'127.0.0.1' identified by '超级用户密码' with grant option;  
> grant proxy on ''@'' to '超级用户'@'127.0.0.1' with grant option;  
>

*  **删除其他授权**

> 查看不安全授权：select \* from mysql.user where user='root' or user='';  
> 删除授权：delete from mysql.user where user='root' or user='';flush privileges;  
> 再次检查：select \* from mysql.user;  
>

*  **授予普通用户增删改查**

> GRANT SELECT, INSERT, UPDATE, DELETE ON 数据库名.\* TO '普通用户'@'127.0.0.1'  IDENTIFIED BY '普通用户密码';  
>

**6.上传数据文件，导入数据库**

**7.更改配置文件**
