Centos 6,7 YUM本地源和网络源配置

前言

YUM（全称为 Yellow dog Updater, Modified）是一个在Fedora中的Shell前端软件包管理器。基于RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软体包，无须繁琐地一次次下载和安装。文章以RHEL(Red Hat Enterprise Linux)配置YUM源为例分享YUM常用命令技巧以及如何搭建ISO本地源和CentOS YUM源。

YUM是一个安装，卸载和搜索软件包的工具

YUM常用命令

列举平时做常用的几组YUM命令

#清除缓存目录 yum clean all #更新缓存 yum makecache #使用YUM查找软件包 yum search telnet #用YUM安装软件包 yum install telnet #用YUM删除软件包 yum remove telnet #安装更新软件 yum update yum update telnet

本地YUM源

无论直接加载ISO还是拷贝文件来搭建本地YUM源都是很简单的

搭建YUM服务器

选择ftp或http等方式多可以，偷懒必须要简单有效

YUM服务端

#安装apache yum install httpd* #编辑apache配置文件 cd /etc/httpd/conf cp httpd.conf httpd.conf.bak #删除测试启动服务 rm -f /etc/httpd/conf.d/welcome.conf /var/www/error/noindex.html #拷贝文件到目录或者修改httpd.conf中的DocumentRoot cp -r /tmp/repo /var/www/html cd /var/www/html chmod -R 755 repo/ #重启apache服务 并设置服务自启动 service httpd restart chkconfig httpd on chkconfig --list | grep httpd httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
