​​Ubuntu系统上双节点部署OpenStack​​



​安装和部署双节点OpenStack​

​介绍：​

1、宿主机：Win10操作系统

2、在VMware下创建两台虚拟机：

devstack-controller：控制节点 + 网络节点 + 块存储节点 + 计算节点

devstack-compute：计算节点

3、方法：利用Devstack部署OpenStack


​前期准备工作：​

1、下载ubuntu镜像，我用的是ubuntu-14.04.5-server-amd64版本

2、下载vmware workstation，我用的是vmware workstation 12版本

3、下载xshell/SecureCRT/Putty，用于ssh连接虚拟机，方便复制代码

4、安装完vmware后，点击编辑，启动虚拟网络编辑器，选择vmnet8，依次设置子网ip、子网掩码、点击NAT设置，修改网关为192.168.213.2（192.168.213.1默认分给宿主机）

​一、安装控制节点：devstack-controller​

步骤：

​1、安装虚拟机和操作系统：​

内存至少6G，硬盘容量至少在40G以上

CPU一定开启虚拟化，一个默认网卡设置成NAT，添加两个网卡，设置成仅主机模式，然后启动虚拟机，安装操作系统。

安装完毕，进入系统

设置root密码：sudo passwd

sudo和su是不一样的，

sudo：输入当前用户的密码 allen

su：输入切换后的用户密码

​2、通过Xshell远程连接虚拟机:SSH（secure shell）协议：安全外壳协议​

注：若连接不成功，修改ssh_config /etc/ssh/



vi /etc/ssh/ssh_config
PemitRootLogin yes

service ssh restart



问题1：没有sshd_config文件，需要安装openssh-server：apt-get install openssh-server

问题2：vi编辑器无法编辑，需要安装vim编辑器：apt-get install vim

3、配置三个网卡：（*）



auto eth0
iface eth0 inet static 
address 192.168.213.10
netmask 255.255.255.0
gateway 192.168.213.2
dns-nameserver 114.114.114.114

auto eth1 
iface eth1 inet manual

auto eth2
iface eth2 inet manual



4、修改Ubuntu14.04的apt源为国内的阿里云的源：



cp /etc/apt/sources.list /etc/apt/sources.list.back
vi /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse



配置DNS服务器：



vi /etc/resolv.conf
nameserver 8.8.8.8 
nameserver 8.8.4.4



更新软件源和软件：



apt-get update
apt-get upgrade



​5、安装pip并修改pip源：​



apt-get install python-pip
mkdir ~/.pip
vi ~/.pip/pip.conf



添加



[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com



​6、安装git：​



apt-get install git



7、下载devstack：



git clone http://git.trystack.cn/openstack-dev/devstack.git -b stable/ocata



8、创建stack用户：



devstack/tools/create-stack-user.sh
mv devstack /opt/stack
chown -R stack:stack /opt/stack/devstack



9、切换到stack用户并修改pip源：



su stack
mkdir ~/.pip
vi ~/.pip/pip.conf



添加



[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com



10、设置Devstack的配置文件：



[[local|localrc]]

MULTI_HOST=true
HOST_IP=192.168.213.10 # management & api network 
LOGFILE=/opt/stack/logs/stack.sh.log

# Credentials 
ADMIN_PASSWORD=admin

Q_AGENT=linuxbridge 
ENABLE_TENANT_VLANS=True 
TENANT_VLAN_RANGE=3001:4000 
PHYSICAL_NETWORK=default

LOG_COLOR=False 
LOGDIR=$DEST/logs 
SCREEN_LOGDIR=$LOGDIR/screen

# use TryStack git mirror 
GIT_BASE=http://git.trystack.cn 
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git 
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git
