CentOS6.5系列默认安装的是MySQL5.1版本,并且默认的repo里也没有高版本的MySQL。

卸载低版本MySQL

先通过

rpm -qa|grep mysql

命令查到mysql安装包详细的名称。然后用命令

rpm -e mysql-**** --nodeps

卸载即可

添加MySQL5.7 Repo源

在目录/etc/yum.repos.d/下新建mysql-community.repo文件,内容如下:

[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=

配置GPG Key

/etc/pki/rpm-gpg/ 目录下新建RPM-GPG-KEY-mysql 文件,从MySQL5.7的官方文档(http://dev.mysql.com/doc/refman/5.7/en/checking-gpg-signature.html)拷贝如下Key内容至该文件:
