yum源配置

**1、本地yum源，首先挂载iso文件，确保光盘挂载点有文件**

在设备状态全部打勾

选择使用iso映像文件

**如果在配置yum源过程中遇到****yum被another app lock使用下面命令**

**rm -f /var/run/yum.pid**

创建挂载点
    mkdir -p /mnt/local
    将iso文件挂载到指定挂载点
    mount /dev/cdrom /mnt/local
    [root@xuexi yum.repos.d]# ls  /mnt/local
    
    CentOS_BuildTag  EULA  images    LiveOS   repodata       RPM-GPG-KEY-CentOS-Testing-7
    
    EFI              GPL   isolinux  Packages  RPM-GPG-KEY-CentOS-7  TRANS.TBL

**2、yum的一切配置信息都存储在一个叫yum.repos.d目录下的配置文件中。所以跳转到/etc/yum.repos.d目录下**

cd /etc/yum.repos.d

**3、创建一个新的yum源配置文件，yum源配置文件的结尾必须是.repo**

vim CentOS7.repo

内容如下：

[CentOS7]                  //yum的ID，本地唯一，用于区分不同yum源
    name=CentOS-server         //描述信息
    baseurl=file:///mnt/local        //前面的file://是协议，后面的/mnt是光盘挂载点
    enabled=1                  //1启用yum源，0禁用yum源
    gpgcheck=0                 //1使用公钥验证rpm包的正确性，0不验证

保存退出后就可以开始验证了。

如果启用公钥验证，需要配置公钥gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

**4、接着清空yum已存在的源信息（缓存）**

**yum clean all**

**yum makecache**

**yum repolist //验证local yum源是否配置成功**

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