原因1

系统中已有mysql相关的文件了。

Linux安装时默认会有些MySQL相关文件。

输入rpm -qa|grep mysql命令查看系统中是否已有mysql，发现已有了

解决1

所以执行需要卸载掉自带的mysql，执行rpm -e --nodeps mysql-libs命令，而mysql-libs上面的文件名

再次查找，就没有mysql了，可以进行安装了，需要注意安装的顺序，安装的顺序如下：

原因2

我安装的mysql包是32位的，而我Linux系统是CentOS7并且64位的。

可以使用uname -a命令查看Linux系统是32位还是64位

解决2

从官网上下载64位的安装包进行安装。注意根据自己的系统版本来选择。

原因3

即我们要安装的包和系统已有的包发生了冲突：

解决3

执行yum -y remove mariadb-libs-1:5.5.68-1.el7.x86_64命令移除冲突的包，其中mariadb-libs-1:5.5.68-1.el7.x86_64就是冲突的包名，卸载产生的日志如下：

[root@localhost mysql]# yum -y remove mariadb-libs-1:5.5.68-1.el7.x86_64
