在这篇文章(http://blog.csdn.net/dylloveyou/article/details/77148560)中，我们已经部署了单节点的OpenStack环境，这次我们尝试部署一个多节点的环境(包括1个controller节点，1个compute节点，1个storage节点)，之前的单节点因为已经安装了kolla-ansible和docker registry，我们把它当做部署节点。
1. 环境准备
新创建3台虚拟机，分别作为controller节点，compute节点，storage节点。其中controller节点3张网卡，compute、storage节点2张网卡。操作系统为centos7.4
1）关闭Selinux
vi /etc/sysconfig/selinux
SELINUX=disabled2）关闭firewalld
systemctl stop firewalld
systemctl disable firewalld3）设置主机名，hosts文件
vi /etc/hosts
192.168.128.77 control01
192.168.128.85 controller
192.168.128.86 compute
192.168.128.87 storage4）storage节点加盘
storage节点新加一块磁盘，作为cinder的lvm后端
加完后重启系统，可以查看到新加的磁盘
[root@storage ~]# fdisk -l
Disk /dev/sdb: 10.7 GB, 10737418240 bytes, 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/sda: 10.7 GB, 10737418240 bytes, 20971520 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000d78d5
Device Boot Start End Blocks Id System
/dev/sda1 2048 20971519 10484736 8e Linux LVM
......创建pv、vg
[root@storage ~]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created.
[root@storage ~]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created修改配置
vi /etc/lvm/lvm.conf
修改 devices 下面的
filter = [ "a/sda/", "a/sdb/", "r/.*/"] 重启lvm服务
systemctl restart lvm2-lvmetad.service5）确认节点配置
controller 3 张网卡
compute 2 张网卡
storage 2 张网卡(其实一张即可，因为不需要tunnel网络)
storage 2 块硬盘
每个主机的eth0网卡作为 API&Management 网络，使用的是“NAT模式”
每个主机的eth1网卡作为 Tenant(VM) 网络，是承载VxLAN的底层网络，使用的是“仅主机模式 ”
controller节点也作为网络节点，需要模拟OpenStack的外网，增加网卡eth2，这里也选择“仅主机模式”
关于如何应用OpenStack的OVS+vxlan网络模式，请参考：http://blog.csdn.net/dylloveyou/article/details/72639187
关于如何修改CentOS7的网卡名称，请参考：http://blog.csdn.net/dylloveyou/article/details/78697896
2.安装docker
1）加入Docker的repo源
# tee /etc/yum.repos.d/docker.repo << 'EOF'
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF 2）安装Docker 1.12.6
yum install docker-engine-1.12.6 docker-engine-selinux-1.12.6 -y3）设置Docker
mkdir /etc/systemd/system/docker.service.d
tee /etc/systemd/system/docker.service.d/kolla.conf << 'EOF'
[Service]
MountFlags=shared
EOF4）重启相关服务
systemctl daemon-reload
systemctl enable docker
systemctl restart docker5）编辑/usr/lib/systemd/system/docker.service文件
ExecStart=/usr/bin/dockerd --insecure-registry 192.168.128.77:40006）重启Docker服务
systemctl daemon-reload
systemctl restart docker3.配置免密登录
部署节点和其他节点免密登陆
[root@control01 ~]# ssh-keygen
[root@control01 ~]# ssh-copy-id controller
[root@control01 ~]# ssh-copy-id compute
[root@control01 ~]# ssh-copy-id storage4.部署OpenStack
1）停止部署节点容器
因为部署节点之前已经部署了All in One的OpenStack，为了降低虚拟机的资源占用(我是用笔记本上面的虚拟机做的实验)，先停止本节的的OpenStack相关容器。
[root@control01 ~]# cd /root/kolla-ansible-4.0.3.dev36/tools/
[root@control01 tools]# . kolla-ansible stop查看只剩registry容器在运行
[root@control01 tools]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b18c5accabc2 registry "/bin/registry serve " 3 months ago Up 22 minutes 0.0.0.0:4000->5000/tcp registry2）修改multinode文件
[root@control01 ~]# cd /root/kolla-ansible-4.0.3.dev36/
[root@control01 kolla-ansible-4.0.3.dev36]# cp ansible/inventory/* /home/
[root@control01 ~]# cd /home
[root@control01 home]# ls
all-in-one multinode
[root@control01 home]# cp multinode mymultinode[root@control01 home]# vi mymultinode
[control]
controller
[network]
controller
[compute]
compute
[monitoring]
controller
[storage]
storage
......里面的内容很好理解，表示一个控制节点 controller，网络节点也安装到控制节点，一个计算节点 compute ，一个存储节点 storage，后面的部分不用修改
3）修改global和password配置文件
[root@control01 ~]# cd /etc/kolla/
[root@control01 kolla]# vi globals.ymlkolla_internal_vip_address: "192.168.128.85" 外部访问地址，如果是非HA环境，是控制节点IP
docker_registry: "192.168.128.77:4000" 镜像库，用部署节点的镜像库
docker_namespace: "99cloud"
network_interface: "eth0" 网络接口，默认就这一个接口，这里我们以eth0作为API网络
api_interface: "{{ network_interface }}" 用的是eth0
tunnel_interface: "eth1" eth1作为vxlan的承载网络
neutron_external_interface: "eth2" eth2作为外部网络
enable_cinder: "yes" 启用cinder
enable_cinder_backend_lvm: "yes" cinder后端用lvm
cinder_volume_group: "cinder-volumes"
enable_haproxy: "no" 不启用haproxy[root@control01 kolla]# vi passwords.yml
keystone_admin_password: admin admin用户登录密码4）部署前检查
[root@control01 ~]# cd /root/kolla-ansible-4.0.3.dev36/tools/
[root@control01 ~]# . kolla-ansible prechecks -i /home/mymultinode报错 ImportError: No module named docker
TASK [prechecks : Checking docker-py version] **********************************
fatal: [compute]: FAILED! => {"changed": false, "cmd": ["/usr/bin/python", "-c", "import docker; print docker.__version__"], "delta": "0:00:00.012605", "end": "2017-12-02 20:57:39.611343", "failed": true, "failed_when_result": true, "rc": 1, "start": "2017-12-02 20:57:39.598738", "stderr": "Traceback (most recent call last):\n File \"<string>\", line 1, in <module>\nImportError: No module named docker", "stdout": "", "stdout_lines": [], "warnings": []}
......解决：在各个节点安装 python-docker-py
yum install python-docker-py- 再次执行检查，没有问题，开始部署
5）部署
[root@control01 tools]# . kolla-ansible deploy -i /home/mymultinode
开始部署，等待大约20分钟，部署完成，一般不会有什么问题，如果有问题，则需要根据报错及容器日志查找原因
登录dashboard
http://192.168.128.85
登录系统，查看各个服务正常，表明部署成功。
可以通过docker ps命令查看各个节点运行的容器
[root@controller ~]# docker ps
