安装rpm包：MySQL-community-client-5.7.13-1.el7.x86_64.rpm
报错如下：
/home/mysql>sudo rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm
[sudo] password for *****:
warning: mysql-community-client-5.7.13-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
mysql-community-libs(x86-64) >= 5.7.9 is needed by mysql-community-client-5.7.13-1.el7.x86_64
mariadb is obsoleted by mysql-community-client-5.7.13-1.el7.x86_64
解决办法：安装包后面增加2个参数（安装时不再分析包之间的依赖关系而直接安装）
/home/mysql>sudo rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm --nodeps --force
