很奇怪，linux下rpm软件安装的问题，为什么我删除mysql的时候说没有安装，我安装的时候又提示已经安装！！

Question

[root@test1 Packages]# rpm -qa |grep mysql
mysql-5.1.47-4.el6.i686
mysql-devel-5.1.47-4.el6.i686
mysql-libs-5.1.47-4.el6.i686

[root@test1 Packages]# rpm -e mysql-libs-5.1.47-4.el6.i686.rpm
error: package mysql-libs-5.1.47-4.el6.i686.rpm is not installed
[root@test1 Packages]# rpm -iv mysql-libs-5.1.47-4.el6.i686.rpm
Preparing packages for installation...
package mysql-libs-5.1.47-4.el6.i686 is already installed

Answer 1

应该是把最后的.rpm去掉，rpm是包名，软件名是
mysql-libs-5.1.47-4.el6.i686

rpm -ev mysql-libs-5.1.47-4.el6.i686

Answer 2

把后面的版本号去掉 rpm -e mysql-libs
