检查网卡必须有两个以上
默认的系统安装库中的软件可能已经过时，默认需要满足以下条件 stable/mitaka分支对依赖包版本的需求:
| Component | Min Version | Max Version | Comment |
|---|---|---|---|
| Ansible | 1.9.4 | <2.0.0 | On deployment host |
| Docker | 1.10.0 | none | On target nodes |
| Docker Python | 1.6.0 | none | On target nodes |
| Python Jinja2 | 2.6.0 | none | On deployment host |
stable/newton分支对依赖包版本的需求:
| Component | Min Version | Max Version | Comment |
|---|---|---|---|
| Ansible | 2.0.0 | none | On deployment host |
| Docker | 1.10.0 | none | On target nodes |
| Docker Python | 1.6.0 | none | On target nodes |
| Python Jinja2 | 2.8.0 | none | On deployment host |
a. 安装pip
yum install epel-release yum install python-pip pip install -U pip yum install python-devel libffi-devel gcc openssl-devel
b. 安装ansible
yum install ansible
c. 安装docker
推荐安装官方的docker，不要yum安装，版本必须要大于1.10.0，不等于1.13.0
# 1. 安装docker curl -sSL https://get.docker.io | bash # 检查版本 docker --version # 2. 配置docker的systemd unit # 配置dcoker的systemd unit，如果MountFlags选项配置错误，kolla-ansible部署neutron-dhcp-agent的时候会出错 # Create the drop-in unit directory for docker.service mkdir -p /etc/systemd/system/docker.service.d # Create the drop-in unit file tee /etc/systemd/system/docker.service.d/kolla.conf <<-'EOF' [Service] MountFlags=shared EOF # 3. 重启docker systemctl daemon-reload systemctl restart docker # 4. 安装docker python的库 yum install python-docker-py
d. 时间同步
openstack，rabbitMQ和ceph需要所有的主机时间同步来确保正确的消息通信，拿ceph来说，如果主机之间时间差了0.05秒以上，ceph就会不爽了。这种情况下，特别需要安装时间同步服务ntpd
yum install ntp
systemctl enable ntpd.service
systemctl start ntpd.service
e. disable libvirt
libvirt默认在许多linux发行版上启动，需要在所有的目标主机上禁用它，因为同时只有一个libvirt可以运行
systemctl stop libvirtd.service systemctl disable libvirtd.service
# 1. 安装kolla and kolla-ansible pip install kolla pip install kolla-ansible # 2. 拷贝配置文件 cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/kolla/ # 3. 拷贝inventory文件到当前目录 cp /usr/share/kolla-ansible/ansible/inventory/* .
单点安装无需配置local registry，多点需要安装

此处一直build不成功，网查有两个解决方案
- 重试多次，因为是从网上获取docker的镜像，可能由于网络问题导致build不成功(但是我多次尝试均未成功)
- 可以直接网上自己下载完整镜像包，然后导入本地(未来得及测试)
