[stack@controller devstack]$ ./stack.sh
2016-10-14 09:55:19.480 | ./stack.sh: line 488: generate-subunit: command not found
上面报错执行下面三条命令
[stack@controller devstack]$ sudo yum install python-pip -y
[stack@controller devstack]$ sudo pip install --upgrade pip
[stack@controller devstack]$ sudo pip install --upgrade pip
如果再失败，删除再重来，可能要多次，我是没有成功过
[stack@controller devstack]$ ./unstack.sh
[stack@controller devstack]$ ./stack.sh
