YUM配置修改

本文主要是介绍YUM配置修改,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

一、背景

     linux服务器需要下载一些依赖包,如果服务器能上外网,除了DNS配置,还需要YUM(/etc/yum.repos.d)有能下载的地方,有些操作系统版本自带的YUM配置不能去公网拉取依赖包(本地YUM源除外,可参考我的博客https://www.cnblogs.com/zgt-edu-cn/p/15525305.html)

二、YUM源文件配置/etc/yum.repos.d,做此操作之前,可以新建一个文件夹

/etc/yum.repos.d/bak,把原有YUM源移动到新文件夹中,详细操作如下 

 

#graphically 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-$releasever - Base - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

#released updates
[updates]
name=CentOS-$releasever - Updates - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
baseurl=http://mirrors.163.com/centos/$releasever/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-$releasever - Plus - 163.com
baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 

 

三、清理本地YUM残留

 

 

1、清除YUM缓存

yum clean all

 

 

 2、 就是把服务器的包信息下载到本地电脑缓存起来

yum makecache

  

3、更新软件仓库  

 

四、下载测试,成功
