https://docs.openstack.org/project-deploy-guide/openstack-ansible/pike/index.html
步骤如下：
一、Prepare the deployment host
centos 7.4
# yum upgrade
# yum install https://rdoproject.org/repos/openstack-pike/rdo-release-pike.rpm
# yum install git ntp ntpdate openssh-server python-devel \
sudo '@Development Tools'
# systemctl stop firewalld
# systemctl mask firewalld
# git clone -b 16.0.6 https://git.openstack.org/openstack/openstack-ansible \ /opt/openstack-ansible
# scripts/bootstrap-ansible.sh
运行结果如下：
PLAY RECAP *******************************************************************************************************************************
localhost : ok=4 changed=3 unreachable=0 failed=0
二、Prepare the target hosts
centos 7.4
# yum upgrade
# uname -r
# yum install bridge-utils iputils lsof lvm2 \ ntp ntpdate openssh-server sudo tcpdump
# echo 'bonding' >> /etc/modules-load.d/openstack-ansible.conf # echo '8021q' >> /etc/modules-load.d/openstack-ansible.conf
# systemctl enable ntpd.service
# systemctl start ntpd.service
三、Configure the deployment
1、SSH免秘钥登录
#ssh-keygen
ssh-copy-id 10.20.0.161
2、参考： Appendix A: Example test environment configuration
cp -r /opt/openstack-ansible/etc/openstack_deploy /etc/openstack_deploy
3、
# cd /opt/openstack-ansible/scripts
# python pw-token-gen.py --file /etc/openstack_deploy/user_secrets.yml
四、Run playbooks
1、检查配置文件
/opt/openstack-ansible/playbooks
# openstack-ansible setup-infrastructure.yml --syntax-check
运行结果如下：
Variable files: "-e @/etc/openstack_deploy/user_secrets.yml -e @/etc/openstack_deploy/user_variables.yml "
[DEPRECATION WARNING]: docker is kept for backwards compatibility but usage is discouraged. The module documentation details page may
explain more about this rationale..
This feature will be removed in a future release. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.
playbook: setup-infrastructure.yml
2、配置主机
/opt/openstack-ansible/playbooks
# openstack-ansible setup-hosts.yml
在部署过程中安把相关模块拷贝到/tmp/ansible相关目录，可进去查看相关文件和脚本。
结果如下：
PLAY RECAP *******************************************************************************************************************************

中间遇到网络问题，系统问题比较多，花了2天多的时间解决了。
（1）网络问题，官方网站是基于ubuntu写的配置文件/etc/network/interfaces，而我用的centos7.4的系统，没有这个配置文件，需要重新理解官方的配置，花了2天多的时间。
（2）
ok: [infra1] => {
"msg": "Failed writing to \"/sys/fs/cgroup/pids/init.scope/pids.max\". While\nwe prefer setting this option it's not required. See the following\nissues on why this is desired and what can be done when the cgroup\nhierarchy exists.\n * https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1497420\n * https://github.com/lxc/lxc/issues/713\n * https://bugs.archlinux.org/index.php?do=details&action=details.addvote&task_id=47303\n"
}
原因是系统差异，缺少init.scope的目录
/sys/fs/cgroup/pids/init.scope
（3）其它可能就是网络的原因了，需要重新运行脚本。
3、
# openstack-ansible setup-infrastructure.yml
这里遇到了个错误,没有解决。

查看lxc的log发现如下的错误，没有解决，由于时间关系，没有继续。
