我认为yum在安装MySQL 5.1时遇到问题，因为已经有了一个预先安装的MySQL 5.5。
我想干净地删除MySQL 5.5（我用PHP和Python有5.5的问题）。
我删除了与MySQL 5.5相关的每个文件夹和文件：
yum remove mysql-server rm -i /usr/bin/mysq* rm -R /var/lib/mysql/ /usr/share/mysql/ /usr/lib64/mysql/ /usr/include/mysql/
我键入find / -name mysql ，我得到
/usr/lib64/perl5/auto/DBD/mysql /usr/lib64/perl5/DBD/mysql
现在，当我尝试yum install mysql-server.x86_64我得到以下错误：

我删除了名为mysql每个文件和文件夹，我是否需要删除这个MySQL-client-5.5.20-1.linux2.6.x86_64软件包？ 如果是这样，我该怎么做？
是的，你会想要删除MySQL 5.5客户端，以消除冲突。 尝试
rpm -e MySQL-client-5.5.20-1.linux2.6.x86_64 rpm -e MySQL-devel-5.5.20-1.linux2.6.x86_64
仔细检查一下，mysql包已经被彻底删除了
yum list installed | grep -i mysql
如果发现任何东西，请删除
yum erase <package-name>
如果还有没有安装的软件包。 输出为冲突引用的目录列表保留所有文件，因此…必须删除！
编辑：是的，删除MySQL客户端软件包。 这实际上似乎是冲突。
