需要安装这么多的依赖，yum试了没法，如果手动下载需要安装那么多依赖，真的费时
解决方法：
换一个安装包，下载一个带有依赖的不就解决了
下载地址：
http://mirror.neu.edu.cn/mysql/Downloads/MySQL-5.6/MySQL-5.6.28-1.linux_glibc2.5.i386.rpm-bundle.tar
这是一个镜像网站，速度较快
下载下来进行解压
如果在安装的时候出现这个错误，我当时出现了依赖冲突

既然告知我们冲突，我们就把他干掉
找到 mariadb相关的依赖
rpm -qa | grep mariadb干掉：
rpm -e --nodeps 将上面找到的依赖放上来当时我找了这三个依赖，故而我干掉这三个
rpm -e --nodeps mariadb-libs-5.5.60-1.el7_5.x86_64 mariadb-devel-5.5.60-1.el7_5.x86_64 mariadb-5.5.60-1.el7_5.x86_64然后安装就没问题了
