openstack ocata版（脚本）控制节点安装

一、初始化环境：

1、更换yum源：

yum install -y wget 
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache

2、下载openstack的软件包

yum -y install centos-release-openstack-ocata
yum -y upgrade
yum -y install python-openstackclient
yum -y install chrony
yum -y install mariadb mariadb-server python2-PyMySQL
yum -y install rabbitmq-server
yum -y install memcached python-memcached
yum -y install openstack-keystone httpd mod_wsgi
yum -y install openstack-glance
yum -y install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api
yum -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtable

3、安装python3

yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
cd /usr/local/src
wget "https://www.python.org/ftp/python/3.5.0/Python-3.5.0.tgz"
tar -zxvf Python-3.5.0.tgz  && cd Python-3.5.0
mkdir /usr/local/python3
./configure --prefix=/usr/local/python3
make && make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
注：需要安装Paramiko,详见：http://www.cnblogs.com/chimeiwangliang/p/7193187.html

4、关闭selinux 

5、关闭防火墙

systemctl stop firewalld
systemctl disable firewalld

6、配置好ip地址

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 

7、更改hosts文件

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

二、执行脚本：

1、配置时间同步： 

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

2、执行脚本：

1、下载文件：
http://pan.baidu.com/s/1eSyCc2u 密码：39jp
解压到任一目录：
openstack
├── admin-openrc
├── cirros-0.3.5-x86_64-disk.img
├── command_compute.txt
├── command.txt
├── compute-install.py
├── demo-openrc

│   ├── linuxbridge_agent.ini
│   ├── linuxbridge_agent.ini.bak
│   ├── neutron.conf
│   ├── neutron.conf.bak
│   ├── nova.conf
│   └── nova.conf.bak

├── __pycache__
│   ├── order_configfile.cpython-35.pyc
│   └── run_sys.cpython-35.pyc
└── run_sys.py

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。

 三、创建虚拟机：

1、装好计算节点后，不会自动注册（运行下面命令进行注册）：

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

 2、也可以修改/etc/nova/nova.conf文件进行检查：

[scheduler]
discover_hosts_in_cells_interval = 300

3、创建虚拟机：

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
