openstack學習-建立一臺雲主機（七）

1、建立基礎環境

一、檢查網絡是否正常

[root@linux-node1 ~]# openstack  network  agent  list
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+
| ID                                   | Agent Type         | Host                    | Availability Zone | Alive | State | Binary                    |
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+
| 0edfdc1a-f5be-44fe-86d8-4b56b85b1deb | Linux bridge agent | linux-node1.example.com | None              | :-)   | UP    | neutron-linuxbridge-agent |
| 281896e5-6946-4192-95f1-f2d7b8b9d2bc | DHCP agent         | linux-node1.example.com | nova              | :-)   | UP    | neutron-dhcp-agent        |
| bf75c379-beb3-4a5a-b003-5b136e4fcdf9 | Metadata agent     | linux-node1.example.com | None              | :-)   | UP    | neutron-metadata-agent    |
| ee34827e-2af6-40ce-9791-ad13902095ce | Linux bridge agent | linux-node2.example.com | None              | :-)   | UP    | neutron-linuxbridge-agent |
+--------------------------------------+--------------------+-------------------------+-------------------+-------+-------+---------------------------+

二、建立網絡

[root@linux-node1 ~]# openstack network create  --share --external \
  --provider-physical-network provider \
  --provider-network-type flat provider

三、查看網絡是否建立成功

[root@linux-node1 ~]# openstack  network  list
+--------------------------------------+----------+---------+
| ID                                   | Name     | Subnets |
+--------------------------------------+----------+---------+
| 12d6ee7f-ffd5-4887-b884-8aa74d1ac576 | provider |         |
+--------------------------------------+----------+---------+
[root@linux-node1 ~]# 

四、建立子網

[root@linux-node1 ~]# openstack subnet create --network provider \
  --allocation-pool start=192.168.56.100,end=192.168.56.200 \
  --dns-nameserver 223.5.5.5  --gateway 192.168.56.2 \
  --subnet-range 192.168.56.0/24 provider-subnet

五、 建立雲主機類型

[root@linux-node1 ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

六、建立密鑰對

[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# ssh-keygen -q -N ""
[root@linux-node1 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
[root@linux-node1 ~]# openstack keypair list

七、添加安全組規則

[root@linux-node1 ~]# openstack security group rule create --proto icmp default
 [root@linux-node1 ~]# openstack security group rule create --proto tcp --dst-port 22 default

 2、查看建立的實例

 一、查看雲主機類型

[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# openstack flavor list

 

二、查看可用的鏡像 

[root@linux-node1 ~]# openstack image list

 

 三、查看可用的網絡

[root@linux-node1 ~]# openstack network list

 

 四、查看可用的安全組

[root@linux-node1 ~]# openstack security group list

 

3、建立虛擬機

[root@linux-node1 ~]# openstack server create --flavor m1.nano --image cirros \
--nic net-id=5c4d0706-24cd-4d42-ba78-36a05b6c81c8 --security-group default \
--key-name mykey demo-instance
#注意指定網絡的時候須要使用ID，而不是名稱

 

4、查看虛擬機

[root@linux-node1 ~]# openstack server list
[root@linux-node1 ~]# openstack console url show demo-instance
