CentOS6.5 YUM源

一、CentOS6.5创建本地YUM下载源：
1、创建挂载和存放ios目录：
   mkdir -p /mnt/cdrom /mnt/centosyum
2、将ios挂载到/mnt/cdrom目录下
   mount -t /dev/cdrom /mnt/cdrom
3、将挂载目录下所有内容拷贝到/mnt/centosyum
    cp -fr /mnt/cdrom/* /mnt/centosyum
4、配置本地yum
     cd /etc/yum.repos.d/
     mv CentOS-Base.repo CentOS-Base.repo.bak
     mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
     mv CentOS-Vault.repo CentOS-Vault.repo.bak
     vim CentOS-Media.repo
###########
    [c6-media]
     name=CentOS-$releasever - Media
     baseurl=file:///mnt/centosyum  #本地源
                file:///media/cdrom/
                file:///media/cdrecorder/
      gpgcheck=1 #检查GPG-KEY，0为不检查，1为检查
      enabled=1   #使用此yum源(0为不启用，1为启用)
      gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
###########
     yum clean all #清除yum缓存
     yum list        #显示yum安装包列表
二、CentOS6.5网络YUM下载源：
1、添加DNS：
    vim /etc/resolv.conf
    #####
    nameserver 202.106.0.20
     nameserver 8.8.8.8
    #####
2、系统自带配置不需更改(系统自带centos6官方下载源)。
    /etc/yum.repos.d
    CentOS-Base.repo  
    CentOS-Debuginfo.repo
    CentOS-Media.repo  
    CentOS-Vault.repo
