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/selinuxSELINUX=disabled

2）关闭firewalld

systemctl stop firewalldsystemctl disable firewalld

3）设置主机名，hosts文件

vi /etc/hosts192.168.128.77 control01 192.168.128.85 controller 192.168.128.86 compute 192.168.128.87 storage

4）storage节点加盘
storage节点新加一块磁盘，作为cinder的lvm后端

这里写图片描述

加完后重启系统，可以查看到新加的磁盘

[root@storage ~]# fdisk -lDisk /dev/sdb: 10.7 GB, 10737418240 bytes, 20971520 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk /dev/sda: 10.7 GB, 10737418240 bytes, 20971520 sectorsUnits = sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk label type: dosDisk 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.service

5）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

这里写图片描述

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 Repositorybaseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/enabled=1gpgcheck=1gpgkey=https://yum.dockerproject.org/gpgEOF

2）安装Docker 1.12.6

yum install docker-engine-1.12.6 docker-engine-selinux-1.12.6 -y

3）设置Docker

mkdir /etc/systemd/system/docker.service.dtee /etc/systemd/system/docker.service.d/kolla.conf << 'EOF'[Service]MountFlags=sharedEOF

4）重启相关服务

systemctl daemon-reloadsystemctl enable dockersystemctl restart docker

5）编辑/usr/lib/systemd/system/docker.service文件

ExecStart=/usr/bin/dockerd --insecure-registry 192.168.128.77:4000

6）重启Docker服务

systemctl daemon-reloadsystemctl restart docker

3.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 storage

4.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 psCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMESb18c5accabc2        registry            "/bin/registry serve "   3 months ago        Up 22 minutes       0.0.0.0:4000->5000/tcp   registry

2）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]# lsall-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.yml

kolla_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IPdocker_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eth0tunnel_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cinderenable_cinder_backend_lvm: "yes"    cinder后端用lvmcinder_volume_group: "cinder-volumes"  enable_haproxy: "no"   不启用haproxy

[root@control01 kolla]# vi passwords.ymlkeystone_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

这里写图片描述

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

这里写图片描述

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 psCONTAINER ID        IMAGE                                                                         COMMAND             CREATED             STATUS              PORTS
