yum的一些配置

安装配置Yum

删除原有yum,如果存在的话

rpm -aq|grep yum|xargs rpm -e --nodeps

找到最新版yum rpm 包,使用rpm -ivh 安装

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpm
rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm

但是会有依赖问题,需要先安装依赖,yum的依赖

error: Failed dependencies:
	python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-73.el6.centos.noarch
	yum-metadata-parser >= 1.1.0 is needed by yum-3.2.29-73.el6.centos.noarch
	yum-plugin-fastestmirror is needed by yum-3.2.29-73.el6.centos.noarch

于是,同时注意,这些依赖的旧版本也要清理

清理

rpm -aq|grep python-urlgrabber  # 查看旧的版本
rpm -e --nodeps python-urlgrabber #把旧版本卸载掉,然后安装新版本

安装新版本

yum-plugin-fastestmirror还会依赖yum,yum又依赖yum-plugin-fastestmirror,要一个命令一块安装

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm

安装完可以清理这些安装包

rm -f python-urlgrabber-3.9.1-11.el6.noarch.rpm yum-metadata-parser-1.1.2-16.el6.x86_64.rpm yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm

安装完后 yum repolist 显示已配置的仓库

使用更快的源 http://mirrors.163.com/.help/centos.html

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
cd /etc/yum.repos.d
wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
yum clean all
yum makecache

网易的源下载可到 2.5 MB/s

搜狐也有,但版本太老 http://mirrors.sohu.com/help/centos.html

可以使用清华大学的. https://lug.ustc.edu.cn/wiki/mirrors/help/centos 速度都十分快.
