搭建本地yum源，离线安装openstack

##搭建本地openstack yum源

yum install centos-release-openstack-pike
yum install https://rdoproject.org/repos/rdo-release.rpm
yum -y install reposync
reposync -p <存放目录> #我这里直接把同步下来的目录放在了/var/www/html目录，这样就不需要更改httpd的配置文件了
yum install -y createrepo.noarch
createrepo . #在同步下来的目录都需要执行
yum -y install httpd
systemctl start httpd
systemctl enable httpd
systemctl stop firewalld
systemctl disable firewalld
setenforce 0

修改配置文件 /etc/selinux/config

SELINUX=disabled
