在 Mysql 官网下载 RPM 的 bundle 包并解压。

[root@localhost mysql5.7]# tar xvf mysql-5.7.12-1.el6.x86_64.rpm-bundle.tar

单独安装 Server 包，报依赖关系的错误。

[root@T400-kelong software]# rpm -ivh mysql-community-server-5.7.10-1.el6.x86_64.rpm
warning: mysql-community-server-5.7.10-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
mysql-community-client(x86-64) = 5.7.10-1.el6 is needed by mysql-community-server-5.7.10-1.el6.x86_64
mysql-community-common(x86-64) = 5.7.10-1.el6 is needed by mysql-community-server-5.7.10-1.el6.x86_64

将所需的包添加上，依然报错，缺少另外一个包。

[root@T400-kelong software]# rpm -ivh mysql-community-server-5.7.10-1.el6.x86_64.rpm mysql-community-common-5.7.10-1.el6.x86_64.rpm mysql-community-client-5.7.10-1.el6.x86_64.rpm

error: Failed dependencies:
mysql-community-libs(x86-64) = 5.7.10-1.el6 is needed by mysql-community-client-5.7.10-1.el6.x86_64

将所需的包添加上，继续报错，和系统自带的5.1 版本冲突。
