Linux挂载iso镜像、配置本地yum源

Linux挂载iso镜像、配置本地yum源

1、备份原yum源配置文件

[root@localhost ~]# ll /etc/yum.repos.d/
[root@localhost ~]# mkdir /etc/yum.repos.d.bak
[root@localhost ~]# mv /etc/yum.repos.d/* /etc/yum.repos.d.bak/
[root@localhost ~]# ll /etc/yum.repos.d/
[root@localhost ~]# ll /etc/yum.repos.d.bak/

2、上传镜像文件并挂载

[root@localhost ~]# mkdir /mnt/CentOS7  # 创建挂载目录
[root@localhost ~]# mount /Tools/CentOS-7-x86_64-DVD-2009.iso /mnt/CentOS7  # 挂载
[root@localhost ~]# ll /mnt/CentOS7/

3、新建本地yum源文件

[root@localhost ~]# vim /etc/yum.repos.d/CentOS-local.repo

• [base-local] 本源的名称
• name 名称
• baseurl 源路径
• enabled 是否启用 1-开启 0-不开启
• gpgcheck 是否安全检测 1-开启 0-不开启
• gpgkey 公钥

[base-local]
name=CentOS-local
baseurl=file:///mnt/CentOS7
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

4、清理缓存

[root@localhost ~]# yum clean all 
[root@localhost ~]# yum makecache

5、测试

[root@localhost ~]# yum -y install gcc
