OpenStack实践(一):Ubuntu16.04下DevStack方式搭建p版OpenStack

OpenStack部署方式很多，常见的个人部署方式有DevStack、Rdo、all-in-one、multi-node、multi-HA-node等；企业部署方式有Ansible、SaltStack、Puppet、TripleO、Kolla、Fuel等。其中DevStack是众多开发者们的首选安装方式或工具，该方式主要是通过配置参数，执行shell脚本来安装一个OpenStack的开发环境。

OpenStack开源社区每年都会开两次设计峰会（Design Summit），发布两个正式版本。从2010年的首个版本至今，一共已经出了18个版本，每个版本都有独立名字，取自当次设计峰会所在城市中选一个地名，而且从A开始，然后B、C……。最新的版本是Rocky，字母R正好排序第18位。本文部署的版本为Pike。

本文OpenStack的控制节点和计算节点都是Esxi上新建的虚机，具体配置如下：

控制节点配置：

计算节点配置：

ubuntu安装详见：Ubuntu16.04.5以lvm方式安装全记录

控制节点和计算节点安装步骤相同，只是第6步中的配置不同，实际安装过程中应先装控制节点再装计算节点，本文以计算节点安装为例记录搭建过程。

1.pip安装

root@openstack-computer:~# pipThe program 'pip' is currently not installed. You can install it by typing:apt install python-piproot@openstack-computer:~# apt install -y python-pip

2.代码下载

root@openstack-computer:~# git clone https://git.openstack.org/openstack-dev/devstack -b stable/pike

本文的安装版本为pike

3.创建用户stack

root@openstack-computer:~# lltotal 36drwx------  4 root root 4096 Nov 29 17:02 ./drwxr-xr-x 23 root root 4096 Nov 29 16:32 ../-rw-------  1 root root   49 Nov 29 16:47 .bash_history-rw-r--r--  1 root root 3106 Oct 23  2015 .bashrcdrwx------  2 root root 4096 Nov 29 16:47 .cache/drwxr-xr-x 17 root root 4096 Nov 29 17:02 devstack/-rw-r--r--  1 root root  148 Aug 17  2015 .profile-rw-------  1 root root 3413 Nov 29 16:51 .viminfo-rw-------  1 root root  128 Nov 29 16:47 .Xauthorityroot@openstack-computer:~# devstack/tools/create-stack-user.shCreating a group called stackCreating a user called stackGiving stack user passwordless sudo privileges

4.修改pip源

root用户修改pip源

root@openstack-computer:~# mkdir ~/.piproot@openstack-computer:~# view ~/.pip/pip.conf[global]trusted-host=mirrors.aliyun.comindex-url=https://mirrors.aliyun.com/pypi/simple/

stack用户修改pip源

root@openstack-computer:~# su - stackstack@openstack-computer:~$ mkdir ~/.pipstack@openstack-computer:~$ view ~/.pip/pip.conf[global]trusted-host=mirrors.aliyun.comindex-url=https://mirrors.aliyun.com/pypi/simple/

5.移动devstack目录
将devstack目录由root的家目录移至/opt/stack

root@openstack-computer:~# mv devstack /opt/stackroot@openstack-computer:~# chown -R stack:stack /opt/stack/devstack

6.新建配置文件

控制节点：

[[local|localrc]]MULTI_HOST=true# management & api networkHOST_IP=172.27.34.37LOGFILE=/opt/stack/logs/stack.sh.log# CredentialsADMIN_PASSWORD=adminMYSQL_PASSWORD=loong576RABBIT_PASSWORD=loong576SERVICE_PASSWORD=loong576SERVICE_TOKEN=loong576# enable neutron-ml2-vlandisable_service n-net# Enable LBaaS v2enable_plugin neutron-lbaas https://git.openstack.org/openstack/neutron-lbaas stable/pikeenable_plugin octavia https://git.openstack.org/openstack/octavia stable/pikeenable_plugin neutron-lbaas-dashboard https://git.openstack.org/openstack/neutron-lbaas-dashboard stable/pike# enable FWaaS v2enable_plugin neutron-fwaas https://git.openstack.org/openstack/neutron-fwaas stable/pikeenable_plugin neutron-fwaas-dashboard https://git.openstack.org/openstack/neutron-fwaas-dashboard stable/pikeenable_service q-lbaasv2,octavia,o-cw,o-hk,o-hm,o-api,q-***,q-fwaas-v2,q-svc,q-agt,q-dhcp,q-l3,q-meta,neutronQ_AGENT=linuxbridgeENABLE_TENANT_VLANS=TrueTENANT_VLAN_RANGE=3001:4000PHYSICAL_NETWORK=default# loggingLOG_COLOR=TrueLOGDIR=$DEST/logsSCREEN_LOGDIR=$LOGDIR/screen# use TryStack git mirrorGIT_BASE=http://git.trystack.cnNOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.gitSPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git

控制节点ip为：172.27.34.37，admin密码为admin，后面web登陆会用到。q-***星号为v and p and n

计算节点：

stack@openstack-computer:~$ more /opt/stack/devstack/local.conf [[local|localrc]]MULTI_HOST=true# management & api networkHOST_IP=172.27.34.38# CredentialsADMIN_PASSWORD=adminMYSQL_PASSWORD=loong576RABBIT_PASSWORD=loong576SERVICE_PASSWORD=loong576SERVICE_TOKEN=loong576# Service informationSERVICE_HOST=172.27.34.37MYSQL_HOST=$SERVICE_HOSTRABBIT_HOST=$SERVICE_HOSTGLANCE_HOSTPORT=$SERVICE_HOST:9292Q_HOST=$SERVICE_HOSTKEYSTONE_AUTH_HOST=$SERVICE_HOSTKEYSTONE_SERVICE_HOST=$SERVICE_HOSTENABLED_SERVICES=n-cpu,q-agt,neutronQ_AGENT=linuxbridgeENABLE_TENANT_VLANS=TrueTENANT_VLAN_RANGE=3001:4000PHYSICAL_NETWORK=default# vnc configNOVA_VNC_ENABLED=TrueNOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"VNCSERVER_LISTEN=$HOST_IPVNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN# LoggingLOG_COLOR=TrueLOGDIR=$DEST/logsSCREEN_LOGDIR=$LOGDIR/screen# use TryStack git mirrorGIT_BASE=http://git.trystack.cnNOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.gitSPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.gitenable_service placement-api

HOST_IP=172.27.34.38为计算节点ip

本文中参数Q_AGENT配置为linuxbridge，表示网络选择为Linux Bridge方式，如果选择Open vSwitch,则Q_AGENT=openvswitch。

7.部署openstack

stack@openstack-computer:~/devstack$ ./stack.sh

控制节点安装完成：

计算节点安装完成：

8.登陆web

地址为：http://172.27.34.37，用户名密码为配置文件中的admin/admin

至此完成OpenStack安装。

9.卸载

若修改了local.conf则需先卸载再重新安装

卸载命令

stack@openstack-controller:~/devstack$ ./unstack.shstack@openstack-controller:~/devstack$ ./clean.sh
