Redhat7 更换Centos 7 yum源
6、卸载redhat自带的yum
| 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
需要下载python-urlgrabber-3.10-8.el7.noarch.rpm
卸载原先的python-urlgrabber-3.10-4.el7.noarch.rpm
| wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-125.el7.centos.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-29.el7.noarch.rpm |
注意：安装包都在不断更新，请按照包名自己匹配.
8、安装以上下载包
| 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
| 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$releasever更改为centos的版本号7
repo参考：
| # CentOS-Base.repo
# # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-7 – Base – 163.com #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$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 |

12、yum makecache 获取yum列表
