redhat 的更新包只對註冊的用戶生效,因此咱們須要本身手動更改爲CentOS 的更新包,CentOS幾乎和redhat是同樣的,因此無需擔憂軟件包是否可安裝,安裝以後是否有問題。node
一、首先刪除redhat原有的yum ,由於redhat 本來的yum 沒有註冊爲redhat用戶是用不了的。python
rpm -aq|grep yum|xargs rpm -e --nodeps rpm -aq|grep python-iniparse|xargs rpm -e --nodeps
二、下載163的yum 安裝包centos
wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-3.4.3-150.el7.centos.noarch.rpm wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7.3.1611/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-40.el7.noarch.rpm三、安裝下載的rpm包
rpm -ivh *.rpm
[base] name=CentOS-$releasever - Base baseurl=http://mirrors.163.com/centos/7.3.1611/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://mirrors.163.com/centos/7.3.1611/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7 [extras] name=CentOS-$releasever - Extras baseurl=http://mirrors.163.com/centos/7.3.1611/extras//$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/7.3.1611/os/x86_64/RPM-GPG-KEY-CentOS-7 [centosplus] name=CentOS-$releasever - Plus baseurl=http://mirrors.163.com/centos/7.3.1611/centosplus//$basearch/ gpgcheck=1 enabled=0
六、 yum clean all
七、 yum update 測試。 bash
八、 安裝 epel 源 測試
yum install epel-release
