Centos7第三方源的安裝與卸載

一、第三方源的添加：

第三方源下載地址：

http://repoforge.org/use/

選擇合適自己包

我選擇的是EL7的

wget 下載這個包

接着使用rpm -ivh 包名

確認是否添加成功

ls /etc/yum.repos.d/   該目錄下是否新增了rpmforge.repo文件，如果有，說明添加成功

現在試一下使用第三方源，安裝htop（默認沒有該安裝源），提示安裝成功

 二、第三方源的卸載

[root@localhost yum.repos.d]# yum list|grep el8　　#centos7系統不小心加了centos8的安裝源，導致安裝時會出異常報錯，所以我們需要卸載el8相關的源
