大家好,又见面了,我是你们的朋友全栈君。
在安装yum的时候发现网上的方法参差不齐,不是很完整,以下是个人亲测,同时是总结出的最方便的方法,希望能帮助到大家!
- 查看已安装的yum
rpm -qa|grep yum
- 删除已有的yum
rpm -aq|grep yum|xargs rpm -e --nodeps
- 下载以下安装包
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/python-2.7.5-89.el7.x86_64.rpm
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
如果找不到以上版本,可以到http://tel.mirrors.163.com/centos/7/os/x86_64/Packages/下载最新版本
- 安装
rpm -ivh python-2.7.5-89.el7.x86_64.rpm python-iniparse-0.4-9.el7.noarch.rpm --nodeps --force
rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64.rpm --nodeps --force
rpm -ivh yum-3.4.3-168.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm --nodeps --force
- 更改yum源
-
到该网站http://mirrors.163.com/.help/centos.html下载配置文件,重命名为CentOS-Base.repo
-
首先备份/etc/yum.repos.d/CentOS-Base.repo
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
-
下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)
-
运行以下命令生成缓存
yum clean all yum makecache
-
-
修改配置文件
- 运行一下命令打开CentOS-Base.repo文件
cd /etc/yum.repos.d vim CentOS-Base.repo
也可以通过Xftp7软件编辑,更加方便快捷
- 将以下配置更换Centos-Base.repo里的内容
# 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-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus baseurl=https://mirrors.ustc.edu.cn/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
- 配置完成后更新缓存
yum clean all yum makecache
- 完成以上步骤就可以成功在Linux安装上yum啦
