視覺化配置網路-前端
首先要先建立一個openstack使用者，作為另外一個租戶建立一個單獨私有網段。
建立組
建立專案
建立使用者
將openstack-cloud使用者加入組
openstack網路配置
網路-公共網路
首先通過admin登陸，找到管理員->系統，刪除”路由”,網路中的所有內容
第一步
點選public網路，進去新增子網。點選下一步，最後點選建立
第二步
第三步
第四步
檢視子網
網路-私有網路
切換使用者 用“openstack-cloud登陸”
在專案-網路-網路，建立私有網路
第一步
第二步
第三步
完成建立
檢視網路
建立路由
在專案-網路-路由裡面建立
第一步 新建路由
第二步
點選新建的路由，設定公網+私網通訊，點選如下“增加介面”
專案-網路-網路拓撲
出現以下拓撲圖說明網路就可以了
專案-計算-訪問&安全
安全組設定
刪除入口規則
選擇“新增規則”
完成
訪問&安全-金鑰對
去終端切換openstack使用者執行以下命令
[[email protected] ~]$ssh-keygen -t rsa -f cloud.key
匯入金鑰對
新增多個compute節點
NOTE: by default $youranswerfile is called packstack-answer-$date-$time.txt[[email protected] ~]# ls packstack-answers-20160517-215941.txt
packstack-answers-20160517-215941.txt
Change IP addresses
Change the value for CONFIG_COMPUTE_HOSTS from the value of your first host IP address
to the value of your second host IP address. Ensure that the
keyCONFIG_NETWORK_HOSTS exists and is set to the IP address of your first host.
Skip installing on an already existing servers
In case you do not want to run the installation over again on the already configured
servers, add the following parameter to the answerfile:
EXCLUDE_SERVERS=<serverIP>,<serverIP>,...
案例：
[[email protected] ~]# egrep "CONFIG_COMPUTE_HOSTS|CONFIG_NETW
ORK_HOSTS|EXCLUDE_SERVERS" packstack-answers-20160613-231012.txt
EXCLUDE_SERVERS=192.168.2.110
CONFIG_COMPUTE_HOSTS=192.168.2.110,192.168.2.111,192.168.2.112,192.168.2.1
13
CONFIG_NETWORK_HOSTS=192.168.2.110
Re-run packstack with the new values
Run packstack again, specifying your modified answer file:
NOTE: by default $youranswerfile is called packstack-answer-$date-$time.txt
[[email protected] ~]# cp packstack-answers-20160613-231012.txt /hom
e/openstack/
[[email protected] ~]# exit
logout
[[email protected] ~]# sudo packstack --answer-file=packstack-answers-2
