devstack安裝初體驗（ubuntu）

最近剛上手安裝devstack，碰到一些問題，紀錄下來，失敗的主要問題是下載下傳各種源的網絡問題，選擇合适的源很重要。

關于虛拟機網絡，采用橋接，這樣主控端和虛拟機能互通，還要保證虛拟機能通路外網

關于硬體配置，記憶體4G以上，不然nova服務啟動，會報記憶體配置設定失敗的錯誤

步驟：

1，首先安裝git

sudo apt-get install git
           

 2，擷取devstack源代碼(liberty版本)

git clone https://git.openstack.org/openstack-dev/devstack -b stable/liberty
           

3，擷取完之後進行一些修改

• 更新ubuntu的源為國内源

                重新載入源，檔案路徑：/etc/apt/sources.list

                更改内容為國内源，國外的源由于有限制使用起來經常會失敗，提供一下阿裡的源 

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

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

        将上述内容寫入sources.list然後執行下述指令更新（保險做法将原來的sources.list備份一下，下述指令是清除已安裝的東西然後再更新）

sudo rm -fR /var/lib/apt/lists/*
sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade
      

• 更改get-pip.sh的源路徑

                  将devstack/tools/install_pip.sh 的PIP_GET_PIP_URL的變量路徑改為https://coding.net/u/xiaoquqi/p/pip/git/raw/master/contrib/get-pip.py

• 在devstack下增加localrc檔案（新版本名字為local.conf，詳細用法參考官方文檔）

            比較重要的檔案( 将HOST_IP改成自己的IP)

DEST=/opt/stack



# SCREEN_LOGDIR=$DEST/logs/screen


HOST_IP=200.21.101.203 # controller ip

MULTI_HOST=True

# LOGFILE=$DEST/logs/stack.sh.log

SERVICE_TOKEN=0210

ADMIN_PASSWORD=0210

MYSQL_PASSWORD=0210

RABBIT_PASSWORD=0210

SERVICE_PASSWORD=0210

#LDAP_PASSWORD=0210

LOCK_PATH=/tmp


# To get a clean install everytime

RECLONE=no

# To enable neutron

enable_service n-net

disable_service q-svc

disable_service q-agt

disable_service q-dhcp

disable_service q-l3

disable_service q-meta

disable_service quantum



# Enable the ceilometer services

disable_service ceilometer-acompute,ceilometer-acentral,ceilometer-collector,ceilometer-api


# Enable Heat

disable_service heat h-api h-eng
           

•  更換pip源

             openstack是python項目 好多依賴都要用pip install 當然要換pip源啦

                   執行以下指令即可

mkdir ~/.pip
cat << EOF > ~/.pip/pip.conf
[global]
index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com
EOF
           

•  安裝使用者必須為非root且具有sudo權限的普通使用者（新增名為stack的使用者）         

adduser stack
           

            添加stack的sudo權限

在/etc/sudoers 加上下面一行
stack ALL=(ALL) NOPASSWD: ALL 
           

4，一切準備就緒安裝

cd devstack && ./stack.sh
           

5, 安裝完成會出來資訊，然後登入danshborad就可以玩耍了

          碰到問題：

          oslo.config子產品導入問題

**keystone-manage pki_setup --keystone-user keystone --keystone-group keystone**
Traceback (most recent call last):
  File "/usr/bin/keystone-manage", line 30, in <module>
    from keystone import cli
  File "/usr/lib/python2.7/site-packages/keystone/cli.py", line 19, in <module>
    from oslo.config import cfg
ImportError: No module named oslo.config
           

        安裝一下 oslo.config 子產品就好了
