name = centos
baseurl = file: /// opt / centos
enabled = 1
gpgcheck = 0

mkdir -p /dev/cdrom
mount /dev/cdrom /opt/centos
yum clean all; yum makecache

3.安装vsftpd
yum install -y vsftp
echo “anon_root=/opt” >> /etc/vsftpd/vsftpd
systemctl start vsftpd
systemctl enable vsftp

4. Web page verification

2. Make yum warehouse

yum install -y createrepo

mkdir /dvd/test
createrepo /dev/test
