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

????OpenStack部署方式很多，常見的個人部署方式有DevStack、Rdo、all-in-one、multi-node、multi-HA-node等；企業部署方式有Ansible、SaltStack、Puppet、TripleO、Kolla、Fuel等。其中DevStack是眾多開發者們的首選安裝方式或工具，該方式主要是通過配置參數，執行shell腳本來安裝一個OpenStack的開發環境。

????OpenStack開源社區每年都會開兩次設計峰會（Design Summit），發布兩個正式版本。從2010年的首個版本至今，一共已經出了18個版本，每個版本都有獨立名字，取自當次設計峰會所在城市中選一個地名，而且從A開始，然后B、C……。最新的版本是Rocky，字母R正好排序第18位。本文部署的版本為Pike。

本文OpenStack的控制節點和計算節點都是Esxi上新建的虛機，具體配置如下：

控制節點配置：

計算節點配置：

ubuntu安裝詳見：Ubuntu16.04.5以lvm方式安裝全記錄

控制節點和計算節點安裝步驟相同，只是第6步中的配置不同，實際安裝過程中應先裝控制節點再裝計算節點，本文以計算節點安裝為例記錄搭建過程。

1.pip安裝

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

2.代碼下載

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

本文的安裝版本為pike

3.創建用戶stack

root@openstack-computer:~#?ll
total?36
drwx------??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

drwx------??2?root?root?4096?Nov?29?16:47?.cache/
drwxr-xr-x?17?root?root?4096?Nov?29?17:02?devstack/

root@openstack-computer:~#?devstack/tools/create-stack-user.sh
Creating?a?group?called?stack
Creating?a?user?called?stack
Giving?stack?user?passwordless?sudo?privileges

4.修改pip源

root用戶修改pip源

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

stack用戶修改pip源

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

5.移動devstack目錄
將devstack目錄由root的家目錄移至/opt/stack

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

6.新建配置文件

控制節點：

[[local|localrc]]

MULTI_HOST=true
#?management?&?api?network
HOST_IP=172.27.34.37
LOGFILE=/opt/stack/logs/stack.sh.log

#?Credentials
ADMIN_PASSWORD=admin
MYSQL_PASSWORD=loong576
RABBIT_PASSWORD=loong576
SERVICE_PASSWORD=loong576
SERVICE_TOKEN=loong576

#?enable?neutron-ml2-vlan
disable_service?n-net

#?Enable?LBaaS?v2
enable_plugin?neutron-lbaas?https://git.openstack.org/openstack/neutron-lbaas?stable/pike
enable_plugin?octavia?https://git.openstack.org/openstack/octavia?stable/pike
enable_plugin?neutron-lbaas-dashboard?https://git.openstack.org/openstack/neutron-lbaas-dashboard?stable/pike

#?enable?FWaaS?v2
enable_plugin?neutron-fwaas?https://git.openstack.org/openstack/neutron-fwaas?stable/pike
enable_plugin?neutron-fwaas-dashboard?https://git.openstack.org/openstack/neutron-fwaas-dashboard?stable/pike

enable_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,neutron

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

#?logging
LOG_COLOR=True
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

控制節點ip為：172.27.34.37，admin密碼為admin，后面web登陸會用到。q-***星號為v and p and n

計算節點：

stack@openstack-computer:~$?more?/opt/stack/devstack/local.conf?
[[local|localrc]]

MULTI_HOST=true
#?management?&?api?network
HOST_IP=172.27.34.38

#?Credentials
ADMIN_PASSWORD=admin
MYSQL_PASSWORD=loong576
RABBIT_PASSWORD=loong576
SERVICE_PASSWORD=loong576
SERVICE_TOKEN=loong576

#?Service?information
SERVICE_HOST=172.27.34.37
MYSQL_HOST=$SERVICE_HOST
RABBIT_HOST=$SERVICE_HOST
GLANCE_HOSTPORT=$SERVICE_HOST:9292
Q_HOST=$SERVICE_HOST
KEYSTONE_AUTH_HOST=$SERVICE_HOST
KEYSTONE_SERVICE_HOST=$SERVICE_HOST

ENABLED_SERVICES=n-cpu,q-agt,neutron
Q_AGENT=linuxbridge
ENABLE_TENANT_VLANS=True
TENANT_VLAN_RANGE=3001:4000
PHYSICAL_NETWORK=default

#?vnc?config
NOVA_VNC_ENABLED=True
NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"
VNCSERVER_LISTEN=$HOST_IP
VNCSERVER_PROXYCLIENT_ADDRESS=$VNCSERVER_LISTEN

#?Logging
LOG_COLOR=True
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

enable_service?placement-api

HOST_IP=172.27.34.38為計算節點ip

本文中參數Q_AGENT配置為linuxbridge，表示網絡選擇為Linux Bridge方式，如果選擇Open vSwitch,則Q_AGENT=openvswitch。

7.部署openstack

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

控制節點安裝完成：

計算節點安裝完成：

8.登陸web

地址為：http://172.27.34.37，用戶名密碼為配置文件中的admin/admin

至此完成OpenStack安裝。

9.卸載

若修改了local.conf則需先卸載再重新安裝

卸載命令

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