Red hat7安装yum源

时间 2020-07-21 标签 red hat7 hat 安装 yum

RedHat yum源是收费的，没有注册的Redhat机器是不能使用yum源的。
因此须要本身手动更改为CentOS 的更新包，CentOS几乎和RedHat是同样的，因此无需担忧软件包是否可安装，下面是安装步骤。node

查看RHEL是否安装了yum，如果安装了，那么又有哪些yum包：

[root@localhost ~]# rpm -qa |grep yum
yum-rhn-plugin-2.0.1-4.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-118.el7.noarch

删除redhat自带的yum包，这里用脚本代替，yum.sh

#! /bin/sh
rpm -qa |grep yum
rpm -qa|grep yum|xargs rpm -e --nodeps ##（不检查依赖，直接删除rpm包）
rpm -qa |grep yum ##(再次查看)

下载新的yum软件包。

通常能够进入如下网站上面查看软件包的版本是否升级或者找到本身系统所对应的文件包版本更新；
网易163网络源地址：http://mirrors.163.com/centos/
CentOS网络源地址：http://centos.ustc.edu.cn/centos/
找到本身所须要的版本下载：
//若是找不到，是安装包更新了，你能够到这个网站http://mirrors.163.com/centos/7/os/x86_64/Packages/复制下载连接，而后再下载下来；web

下载并安装，我在home目录下建立了脚本yum.sh，下载并安装这些软件包

防止安装包之间会出现依赖关系，因此将全部yum相关的软件包都下载下来了shell

新建repo 配置文件

[root@localhost yum.repos.d]# vi /etc/yum.repos.d/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

# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

运行yum makecache命令生成缓存

[root@localhost yum.repos.d]# yum clean all
[root@localhost yum.repos.d]# yum makecache
[root@localhost yum.repos.d]# yum update

通过上述六个步骤，新的yum源已经安装完成了，咱们能够用yum install 命令来测试安装是否正常

[root@localhost yum.repos.d]# yum install net-tools
