Openstack Ocata版本+Ubuntu 16.04安裝筆記

環境virtualbox，安裝兩個節點，一個控制節點，一個計算節點，兩個節點都是2c8g，都是雙網卡。硬盤留出80GB。

1.兩個網絡，一個管理網絡，給物理節點上網安裝軟件使用，模式NAT網絡。一個provider網絡，給虛機上網使用，模式Host-only，注意：provider網絡上的網卡必定要容許「混雜模式」，不然節點是沒法ping通openstack建立出來的虛擬機的！！！！

2.查看openstack日誌，在/var/log目錄下，keystone的日誌在/var/log/apache2/keystone目錄下。

3./etc/keystone/keystone-paste.ini is missing a 'pipeline' pipline這個配置不能註釋掉。

4.在編輯/nova/nova.conf文件中[placement]一欄時要注意os_region_name改成RegionOne，不能使用原來的openstack。

5.VIM刪除空白行 :g/^$/d   刪除註釋行 :%s/^#.*$//g

6.配好各個主機的主機名，而且要能經過主機名訪問各節點。

7.阿里雲ubuntu 16的APT源，修改/etc/apt/source.list文件爲如下內容：

deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted

8.horizon遇到Permission denied: '/var/lib/openstack-dashboard/secret_key'錯誤緣由是apache是以www-data用戶啓動，沒有權限訪問文件，執行

chown -R www-data:www-data  secret-key
