centos下刪除用yum安裝的軟件

作者:田逸([email protected])

yum安裝軟件包,方便簡單.但在這個過程中,那些文件和目錄都到哪裏去了呢?到處都是呀!要維護這些文件,很麻煩的.前兩天,我用源碼安裝mysql-proxy,在編譯過程中,老出錯,我就依提示安裝mysql, 爲了儘快完事,我用了yum install mysql.現在我打算重新安裝mysql,因此需要把yum方式安裝的mysql刪除. 

用rpm工具吧,不行呢.挨個刪除文件,更不可行,因爲我不知道究竟安裝了哪些文件,都存放在哪些位置.怎麼辦?還好,yum自己可以完成這個工作. 

現在我們來看一下yum的參數:

[root@test1 ~]# yum 
You need to give some command
usage: yum [options] < grouplist, localinstall, groupinfo, localupdate, resolvedep, erase, deplist, groupremove, makecache, upgrade, provides, shell, install, whatprovides, groupinstall, update, repolist, groupupdate, info, search, check-update, list, remove, clean, grouperase >

其中remove就是刪除命令.好了,我們來執行命令 yum remove mysql ,其輸出如下:

[root@test1 ~]# yum remove mysql

看,很容易就完成了.再來驗證一下: 執行命令mysql,其結果爲:

[root@test1 ~]# mysql
-bash: mysql: command not found

果然刪除了!
