redhat 7 -安装阿里的YUM源
环境：Red Hat Enterprise Linux Server release 7.3 (Maipo)
1、查看本系统安装的yum的包
[root@localhost yum.repos.d]# rpm -qa |grep yum
yum-rhn-plugin-2.0.1-6.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-150.el7.noarch
更新前的YUM包
[root@localhost bak]# rpm -qa | grep yum
yum-3.4.3-168.el7.centos.noarch
yum-langpacks-0.4.2-7.el7.noarch
yum-utils-1.1.31-54.el7_8.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-rhn-plugin-2.0.1-10.el7.noarch这是已经更新yum 后的包
2、手动先下载这些包
下载地址：http://pub.mirrors.aliyun.com/centos/7/os/x86_64/Packages/
python-urlgrabber-3.10-10.el7.noarch.rpm
PackageKit-yum-1.1.10-2.el7.centos.x86_64.rpm
yum-3.4.3-168.el7.centos.noarch
yum-langpacks-0.4.2-7.el7.noarch
yum-utils-1.1.31-54.el7_8.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-rhn-plugin-2.0.1-10.el7.noarch
3、删除原有的YUM
rpm -qa|grep yum|xargs rpm -e --nodeps #删除yum包
python-urlgrabber 先卸载掉python-urlgrabber。安装yum包才会成功
rpm -qa|grep yum|xargs rpm -e --nodeps
4、安装yum 包
上传下专的7个包
rpm -ivh python-urlgrabber-3.10-10.el7.noarch.rpm
rpm -ivh yum-* #安装不成功就使用下面的强行安装
rpm -ivh yum-* --force --nodeps
5、下载Centos yum源
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
修改Centos-7.repo
sed -i 's/$releasever/7/g' /etc/yum.repos.d/Centos-7.repo
或进入vi centos-7.repo
:%s/$releaserver/7/g
6、使用
yum clean all
yum repolist
测试
[root@localhost bak]# yum install -y wget
