下载devstack和前期准备
这里和别人的文章有点出入，git clone devstack的时候需要指定分支，不然安装openstack的时候会提示一个脚本不存在
复制
代码语言：javascript复制
# cd /opt
# git clone https://git.openstack.org/openstack-dev/devstack -b stable/liberty
新建stack用户，修改devstack文件夹所有者
复制
代码语言：javascript复制
# cd /opt/devstack/tools/
# ./create-stack-user.sh
# chown -R stack:stack /opt/devstack
新建local.conf文件，示例如下，按需更改
复制
代码语言：javascript复制
# vim /opt/devstack/local.conf
