Redhat7 替换Centos7 yum源

erwerwe

准备：win主机*1、Redhat最小化安装企业版*1

1、Xshell ssh链接redhat，并切换到root账户（后续按照等操作都在Xshell界面进行）
#这个比较简单，一般redhat ssh开机自启，ps命令能直接查看

2、win主机打开http://mirrors.163.com/centos/7/os/x86_64/Packages/，Ctrl+F查找wget并下载到本地，直接链接：wget-1.14-10.el7_0.1.x86_64.rpm
3、使用WinSCP，以root登录redhat
4、将下载的wget-1.14-10.el7_0.1.x86_64.rpm 传到/tmp目录
5、安装wget

1 2	cd /tmp rpm -ivh wget-1.14-10.el7_0.1.x86_64.rpm

6、卸载redhat自带的yum

1	rpm -qa | grep yum | xargs rpm -e --nodeps

注：a、xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题

       b、--nodeps  强制卸载,不管依赖性
7、下载centos的yum安装包，路径同2，可以直接使用下列链接

1 2 3 4

wget http://mirrors.163.com/centos/7/ ... .4-9.el7.noarch.rpm wget http://mirrors.163.com/centos/7/ ... 7.centos.noarch.rpm wget http://mirrors.163.com/centos/7/ ... 4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7/ ... 1-29.el7.noarch.rpm

注意：安装包都在不断更新，请按照包名自己匹配，当前可用2015-11。

8、安装以上下载包

1 2 3

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm rpm -ivh yum-3.4.3-125.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-29.el7.noarch.rpm

[注] :最后2个需要一起安装，否则会出现依赖性错误

9、下载repo文件，注意切换目录
当然你可以简单点，直接将10中的repo复制，并在yum.repos.d目录新建*******.repo文件

1 2	cd /etc/yum.repos.d/ wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

10、编辑CentOS7-Base-163.repo文件，将其中的$releasever更改为centos的版本号7

此步骤建议下载到本机，使用记事本或notepad打开一键替换，再使用winscp上传到redhat

# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.  You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-7 - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os baseurl=http://mirrors.163.com/centos/7/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-7 - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/7/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-7 - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/7/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-7 - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

11、yum clean all 清除原有缓存

12、yum makecache  获取yum列表
出现下面提示，表示yum更改完成：
Metadata Cache Created

13、yum repolist可以查看源数据

1 2 3 4 5 6

yum repolist repo id                      repo name                             status !base/x86_64                 CentOS-7 - Base - 163.com             8,652 !extras/x86_64               CentOS-7 - Extras - 163.com           275 !updates/x86_64              CentOS-7 - Updates - 163.com          1,707 repolist: 10,634
