ubuntu 上一切都很简单，我使用的是Ubuntu 14.04 LTS
准备环境，查看防火墙。

Rhel 7.2 就要烦很多：先disable iptables, disable selinux.
1. 装brctl. 此处略过下载，创建stack 用户和修改conf文件的过程。

- # The manual check for missing packages is because yum -y assumes
- # missing or failed packages are OK.

- (sudo_with_proxies "${YUM:-yum}" install -y "$@" 2>&1 || echo YUM_FAILED $?) \

- time_stop "yum_install"
- # if we return 1, then the wrapper functions will run an update
- # and try installing the package again as a defense against bad
- # mirrors. This can hide failures, especially when we have
- # packages that are in the "Failed:" section because their rpm
- # install scripts failed to run correctly (in this case, the
- # package looks installed, so when the retry happens we just think
- # the package is OK, and incorrectly continue on).
- if [ "$result" == 2 ]; then
- die "Detected fatal package install failure"
- fi
- return "$result"
- }
可以断定：'Detected fatal package install failure' 意味着yum install -y 某个包出错，在log里面一顿找，发现有些包没有找到，手动装上。
3. 又碰上mariadb 的问题，我安装了更新的 mariadb-libs.
log 如下：

总结下： Ubuntu 14.04 LTS 使用devstack 装openstack ，一路绿灯，没有报错。
Rhel 7.2 出错10次左右，自己手动卸载或者安装N个。
Centos 7.2 可以参考：
