5. root用户目录下配置pip安装源

[root@localhost ~]$ mkdir .pip
[root@localhost ~]$ vi .pip/pip.conf
[global]
index-url=https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host=pypi.tuna.tsinghua.edu.cn

6.下载指定文件(手动下载防止延迟)

[stack@localhost ~]$cd devstack/files

7. 调整防火墙

[root@localhost ~]$vim /etc/selinux/config
SELINUX=permissive
[root@localhost ~]$setenforce 0
[root@localhost ~]$iptables -F
[root@localhost ~]$iptables -X
[root@localhost ~]$iptables -Z

8.安装devstack

[stack@localhost ~]$cd devstack
[stack@localhost devstack]$ ./stack
