openstack部署（五）
运行实例 - 创建公网网络【控制节点】
执行初始化脚本
source admin-openrc.sh
创建网络
neutron net-create public --shared --provider:physical_network public \
--provider:network_type flat
# source admin-openrc.sh
# neutron net-create public --shared --provider:physical_network public \
> --provider:network_type flat
Created a new network:

# 创建子网
neutron subnet-create public 192.168.100.0/24 --name public \
--allocation-pool start=192.168.100.100,end=192.168.100.200 \

# neutron subnet-create public 192.168.100.0/24 --name public \

> --dns-nameserver 8.8.8.8 --gateway 192.168.100.1
Created a new subnet:

#
说明：这里的公网，实际上是虚拟机用的那个网段，我们暂时把它作为公网，在这里因为涉及到dhcp服务，会和局域网内的路由器上的dhcp服务产生冲突，所以需要先把路由器上的dhcp服务关掉。
运行实例 - 创建key 【控制节点】
执行初始化脚本
source demo-openrc.sh
生成密钥
ssh-keygen -q -N ""
nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey
# ssh-keygen -q -N ""
Enter file in which to save the key (/root/.ssh/id_rsa):
# nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey
# 验证密钥
nova keypair-list
增加安全组规则
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
允许ssh 访问
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range| Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp | -1 | -1 | 0.0.0.0/0 | |
+-------------+-----------+---------+-----------+--------------+
# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

复制链接地址到浏览器中打开，未做主机解析的主机名换位ip地址
验证网络（在实例里面）
ping -c 2 192.168.100.1
ping -c2 www.baidu.com测试网络连通性
远程连接实例
首先用nova list 查看实例的ip（为192.168.100.101）
验证ip
ping -c4 192.168.100.101
远程ssh登录 ssh cirros@192.168.100.101密码：cubswin:)
