6.执行yum update
7.执行yum -y install centos-release-openstack-train
8.再次更新yum源
sed -i s/mirror.centos.org/vault.centos.org/g /etc/yum.repos.d/*.repo
sed -i s/^#.*baseurl=http/baseurl=http/g /etc/yum.repos.d/*.repo

CONFIG\_CINDER\_VOLUMES\_SIZE=3000G
CONFIG\_PROVISION\_DEMO=n
12.安装
packstack --answer-file=openstack.txt
13.修改mysql连接数
vi /usr/lib/systemd/system/mariadb.service
