安装mysql的时候时：
错误现象：
[root@localhost opt]# rpm -ivh mysql-server-5.5.32-1.el6.x86_64.rpm preparing... ########################################### [100%] file /usr/share/mysql/charsets/index.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/armscii8.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/ascii.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/cp1250.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/cp1256.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/cp1257.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/cp850.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64 file /usr/share/mysql/charsets/cp852.xml from install of mysql-server-5.5.32-1.el6.x86_64 conflicts with file from package mysql-libs-5.1.61-4.el6.x86_64
错误原因：
原因由包冲突引起的！
解决方法：
先移除冲突的libs包，再进行安装。
yum -y remove mysql-libs-5.1.61*
-y的意思就是不用询问是否remove卸载完成之后，
然后再执行命令
rpm -ivh mysql-server-5.5.32-1.el6.x86_64.rpm
安装mysql就可以成功了，如下：
