实际企业中，大多数服务器不能连接外网，需要安装软件只能通过本地yum仓库（本次实验FTP服务器IP地址：10.0.0.61）。
yum仓库原理图
[oldboy@m01 ~]$ cat /etc/redhat-release CentOS release 6.7 (Final) [oldboy@m01 ~]$ uname -r 2.6.32-573.el6.x86_64 [oldboy@m01 ~]$ uname -m x86_64
准备工作：虚拟机加载ISO文件，确保连接。
请到下面网站中下载最完整安装包作为base库（本文以CentOS-6.7为例）
https://mirrors.aliyun.com/centos-vault/6.7/isos/x86_64/CentOS-6.7-x86_64-bin-DVD1.iso

wget -O /etc/yum.repos.d/epel.repo http://file.kangle.odata.cc/repo/epel-6.repo
cat > /etc/yum.repos.d/saltstack.repo <<EOF [saltstack-repo] name=SaltStack repo for RHEL/CentOS $releasever baseurl=http://archive.repo.saltstack.com/yum/redhat/\$releasever/\$basearch/latest enabled=1 gpgcheck=1 gpgkey=http://archive.repo.saltstack.com/yum/redhat/\$releasever/\$basearch/latest/SALTSTACK-GPG-KEY.pub EOF
说明：由于CentOS 6停更，所以需要将上面三个repo文件的路径改为上述的备用路径（千辛万苦才找到）！
yum clean all
yum makecache
yum install vsftpd createrepo -y
/etc/init.d/vsftpd start
说明：必要的时候检查一下vsftpd服务是否已经启动，即netstat -lntup|grep vsftpd（CentOS7无此命令，可以使用ps -ef |grep vsftpd）。
