systemctl stop firewalld

systemctl disable firewalld

ip addr add dev eth0 10.0.0.11/24

echo 'ip addr add dev eth0 10.0.0.11/24' >> /etc/rc.local

chmod +x /etc/rc.d/rc.local 

1、vi /etc/hosts

# controller

10.0.0.11 controller

# compute1

10.0.0.21 compute1

# compute2

10.0.0.22 compute2

# compute3

10.0.0.23 compute3

# compute4

10.0.0.24 compute4

# block1

10.0.0.51 block1

# object1

10.0.0.52 object1

# object2

10.0.0.53 object2
2、重启服务器：
reboot

1、修改/etc/chrony.conf：

vi /etc/chrony.conf

allow 10.0.0.0/24  #改为

2、启动服务：

systemctl enable chronyd.service

systemctl start chronyd.service

3、可以配置时区（选配）

timedatectl set-timezone Asia/Shanghai

chronyc sources

1、下载文件：

http://pan.baidu.com/s/1eSyCc2u 密码：39jp

解压到任一目录：

2、执行以下命令：

export OS_USERNAME=admin

export OS_PASSWORD=keystone

export OS_PROJECT_NAME=admin

export OS_USER_DOMAIN_NAME=Default

export OS_PROJECT_DOMAIN_NAME=Default

export OS_AUTH_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

3、执行脚本：

python3 openstack-install.py
注：1.有mysql初始化密码为order_configfile.py文件里mysql_root变量的值。
   2.order_configfile.py文件里bridge_port变量的值是桥接网卡名。
   3.order_configfile.py文件里mysql_database_user为各服务的数据库密码。
   4.order_configfile.py文件里keystone_user为各服务的keystone密码。
执行过程中有报错的话会有提示是否继续执行。

1、openstack hypervisor list

+----+---------------------+-----------------+-----------+-------+
| ID | Hypervisor Hostname | Hypervisor Type | Host IP | State |
+----+---------------------+-----------------+-----------+-------+
| 1 | compute1 | QEMU | 10.0.0.21 | up |
+----+---------------------+-----------------+-----------+-------+

2、su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

[scheduler]

discover_hosts_in_cells_interval = 300

1、创建网络：
openstack network create  --share --external --provider-physical-network provider --provider-network-type flat provider

openstack subnet create --network provider --allocation-pool start=192.168.72.0,end=192.168.72.100 --dns-nameserver 8.8.8.8 --gateway 192.168.79.254 --subnet-range 192.168.64.1/20 provider

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

2、创建秘钥：
ssh-keygen -q -N ""

openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

openstack keypair list
3、创建安全组：

openstack security group rule create --proto icmp default

openstack security group rule create --proto tcp --dst-port 22 default
4、创建虚拟机：

openstack flavor list

openstack image list

openstack network list

openstack security group list

openstack server create --flavor m1.nano --image cirros --nic net-id=（网络的ID） --security-group default --key-name mykey provider-instance
5、检查是否创建成功：

openstack server list

openstack console url show provider-instance
