Centos7第三方源的安装与卸载
一、第三方源的添加：
第三方源下载地址：
http://repoforge.org/use/
选择合适自己包
我选择的是EL7的
wget 下载这个包
接着使用rpm -ivh 包名
确认是否添加成功
ls /etc/yum.repos.d/ 该目录下是否新增了rpmforge.repo文件，如果有，说明添加成功
现在试一下使用第三方源，安装htop（默认没有该安装源），提示安装成功
二、第三方源的卸载
[root@localhost yum.repos.d]# yum list|grep el8 #centos7系统不小心加了centos8的安装源，导致安装时会出异常报错，所以我们需要卸载el8相关的源 zabbix-agent.x86_64 4.0.12-1.el7 installed zabbix-release.noarch 4.0-2.el8 installed zlib.x86_64 1.2.7-18.el7 @anaconda Available Packages fping.x86_64 3.16-1.el8 zabbix-non-supported zabbix-agent.x86_64 4.0.14-1.el8 zabbix zabbix-get.x86_64 4.0.14-1.el8 zabbix zabbix-java-gateway.x86_64 4.0.14-1.el8 zabbix zabbix-proxy-mysql.x86_64 4.0.14-1.el8 zabbix zabbix-proxy-pgsql.x86_64 4.0.14-1.el8 zabbix zabbix-proxy-sqlite3.x86_64 4.0.14-1.el8 zabbix zabbix-sender.x86_64 4.0.14-1.el8 zabbix zabbix-server-mysql.x86_64 4.0.14-1.el8 zabbix zabbix-server-pgsql.x86_64 4.0.14-1.el8 zabbix zabbix-web.noarch 4.0.14-1.el8 zabbix zabbix-web-japanese.noarch 4.0.14-1.el8 zabbix zabbix-web-mysql.noarch 4.0.14-1.el8 zabbix zabbix-web-pgsql.noarch 4.0.14-1.el8 zabbix [root@localhost yum.repos.d]# yum remove zabbix-release.noarch #直接remove卸载即可 Loaded plugins: fastestmirror Resolving Dependencies --> Running transaction check ---> Package zabbix-release.noarch 0:4.0-2.el8 will be erased --> Finished Dependency Resolution Dependencies Resolved ======================================================================================= Package Arch Version Repository Size ======================================================================================= Removing: zabbix-release noarch 4.0-2.el8 installed 21 k Transaction Summary ======================================================================================= Remove 1 Package Installed size: 21 k Is this ok [y/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Erasing : zabbix-release-4.0-2.el8.noarch 1/1 Verifying : zabbix-release-4.0-2.el8.noarch 1/1 Removed: zabbix-release.noarch 0:4.0-2.el8 Complete!
