1. 检查系统自带的Mysql，并卸载自带的版本

[root@iZ2366ycl7sZ config]# yum list installed |grep mysql
mysql.x86_64 5.1.73-5.el6_6 @base
mysql-libs.x86_64 5.1.73-5.el6_6 @base
php56w-mysql.x86_64 5.6.40-1.w6 @webtatic </pre>

2. 卸载系统自带的mysql及其依赖

[root@iZ2366ycl7sZ config]# yum -y remove mysql-libs.x86_64

给****CentOS****添加****rpm****源，并且选择较新的源

1）下载rpm包

3）验证是否安装成功

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;”>[root@iZ2366ycl7sZ software]# yum repolist all | grep mysql

4）修改默认版本为5.7

注：如下是截取的老徐之前文章 -》原文 <u style=”box-sizing: border-box;”>http://istester.com/huanjing/134.html</u>

如上，默认是5.6版本可用，如果想安装5.7怎么操作？

有如下两个方法：

方法一：

执行：

yum-config-manager –disable mysql56-community

yum-config-manager –enable mysql57-community-dmr

如上操作，是把5.6禁用，把5.7启用
此法，会有异常情况：
如果执行命令出现如下错误：
-bash: yum-config-manager: command not found
可用执行如下命令解决，然后继续上面的操作命令：
yum -y install yum-utils
注意：如上操作可能有一部分同学的会出现一些问题；好处是操作简单，两个命令搞定～
如果有问题，底部给老徐留言～

方法二：

直接编辑配置文件，简单、直接，基本不会出现错误～

vi /etc/yum.repos.d/mysql-community.repo

把5.6的enabled=0

把5.7的enabled=1

然后保存就ok

Enable to use MySQL 5.5
[mysql55-community]
name=MySQL 5.5 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.5-community/el/6/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
Enable to use MySQL 5.6
[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
Note: MySQL 5.7 is currently in development. For use at your own risk.
Please read with sub pages: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/
[mysql57-community-dmr]
name=MySQL 5.7 Community Server Development Milestone Release
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

如上，颜色标记处。

此时，再执行：

yum repolist all | grep mysql

就可以看到，5.7是启用的

[root@localhost webserver]# yum repolist all | grep mysql
mysql-connectors-community MySQL Connectors Community 启用: 21
mysql-connectors-community-source MySQL Connectors Community – Sourc 禁用
mysql-tools-community MySQL Tools Community 启用: 38
mysql-tools-community-source MySQL Tools Community – Source 禁用
mysql55-community MySQL 5.5 Community Server 禁用
mysql55-community-source MySQL 5.5 Community Server – Sourc 禁用
mysql56-community MySQL 5.6 Community Server 禁用
mysql56-community-source MySQL 5.6 Community Server – Sourc 禁用
mysql57-community-dmr MySQL 5.7 Community Server Develop 启用: 130
mysql57-community-dmr-source MySQL 5.7 Community Server Develop 禁用

如上。

OK，至此，基础准备工作完成。

4. 安装mysql

执行如下命令：

yum install mysql-community-server

<pre style=”box-sizing: border-box; font-family: Monaco, Menlo, Consolas, “Courier New”, monospace; font-size: 12px; white-space: pre-wrap; display: block; padding: 9.5px; margin: 0px 0px 10px; line-height: 1.38462; color: rgb(51, 51, 51); word-break: break-all; overflow-wrap: break-word; background-color: rgb(245, 245, 245); border: 1px solid rgb(204, 204, 204); border-radius: 4px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;”>**[root@iZ2366ycl7sZ software]# yum install mysql-community-server

5. 启动mysql

6. 查看mysql服务状态

7. 查看mysql 初始密码

mysql5.7之后初始密码不再默认为空

其中，最后的xo%LBtyoo2MV 就是密码

8. 命令行登录mysql ，并修改密码

登录之后第一步必须先修改密码，

否则其他操作都执行不了。

修改密码的方法：

alter user root@localhost identified by ‘passwd’;

‘passwd’ 里，填写你的新密码。

新修改的密码中必须包含大小写字母数字及符号

</pre>

End 。
