CentOS7.4+OpenStack-Queens版本部署

一、准备工作、网络选择NAT

创建两台虚拟机：linux-node1、linux-node2

node1：

修改主机名

[root@localhost ~]# hostnamectl set-hostname linux-node1.example.com

[root@localhost ~]# su -

Last login: Sat May 19 18:28:37 CST 2018 from 192.168.43.1 on pts/0

[root@linux-node1 ~]#

配置IP：

[root@linux-node1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32

TYPE=Ethernet

BOOTPROTO=static

NAME=ens32

DEVICE=ens32

ONBOOT=yes

IPADDR=192.168.43.11

NETMASK=255.255.255.0

GATEWAY=192.168.43.2

DNS1=192.168.43.2

关闭防火墙、永久关闭selinux：

[root@linux-node1 ~]# systemctl disable NetworkManager

[root@linux-node1 ~]# systemctl disable firewalld

[root@linux-node1 ~]# setenforce 0

[root@linux-node1 ~]# vi /etc/selinux/config

 

修改hosts文件：

[root@linux-node1 ~]# cat /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.43.11 linux-node1 linux-node1.example.com

192.168.43.12 linux-node2 linux-node2.example.com

配置yum源：

[root@linux-node1 ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

[root@linux-node1 ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

[root@linux-node1 ~]# yum makecache

[root@linux-node1 ~]# yum install wget -y

[root@linux-node1 ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

安装常用工具包：

[root@linux-node1 ~]# yum install -y net-tools vim lrzsz tree screen lsof tcpdump nc mtr nmap

以上的环境都接下来把linux-node1克隆：

然后我们就只修改node2的主机名、IP：

[root@linux-node1 ~]# hostnamectl set-hostname linux-node2.example.com

[root@linux-node1 ~]# su -

Last login: Sat May 19 18:51:51 CST 2018 from 192.168.43.1 on pts/0

[root@linux-node2 ~]#

[root@linux-node2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32

TYPE=Ethernet

BOOTPROTO=static

NAME=ens32

DEVICE=ens32

ONBOOT=yes

IPADDR=192.168.43.12

NETMASK=255.255.255.0

GATEWAY=192.168.43.2

DNS1=192.168.43.2

node1上操作：

安装OpenStack仓库：

innodb_file_per_table = on#使用独享表空间

collation-server = utf8_general_ci #服务器的默认校对规则

character-set-server = utf8 #服务器安装时指定的默认字符集设定

max_connections = 4096 #设置MySQL的最大连接数，生产请根据实际情况设置。

3.启动MySQL Server并设置开机启动

[root@linux-node1 ~]# systemctl enable mariadb.service

[root@linux-node1 ~]# systemctl start mariadb.service

4.进行数据库安全设置

在控制节点上测试Neutron安装

[root@linux-node1 ~]# source admin-openstack.sh

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

 

八、使用命令创建云主机；后者也可以通过web界面创建

1.创建网络

[root@linux-node1 ~]# openstack network create --share --external \

--provider-physical-network provider \

--provider-network-type flat provider

 

2.创建子网

[root@linux-node1 ~]# openstack subnet create --network provider \

--allocation-pool start=192.168.43.100,end=192.168.43.200 \

--dns-nameserver 223.5.5.5 --gateway 192.168.43.2 \

--subnet-range 192.168.43.0/24 provider-subnet

 

3. 创建云主机类型

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

 

4.创建密钥对

[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

 

5.添加安全组规则

[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

 

启动实例

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

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

 

1.查看可用的镜像

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

 

2.查看可用的网络

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

 

3.查看可用的安全组

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

 

4.创建虚拟机

[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

#注意指定网络的时候需要使用ID，而不是名称

 

5.查看虚拟机

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

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

 

九、安装Horizon服务

1.安装Horizon

[root@linux-node2 ~]# yum install -y openstack-dashboard

 

2.Horizon配置

[root@linux-node2 ~]# vim /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "192.168.43.11"

#允许所有主机访问
ALLOWED_HOSTS = ['*', ]

#设置API版本

OPENSTACK_API_VERSIONS = {

"identity": 3,

"volume": 2,

"compute": 2,

}

开启多域支持

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True

设置默认的域

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'

#设置Keystone地址

OPENSTACK_HOST = "192.168.43.11"

OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST

#为通过仪表盘创建的用户配置默认的 user 角色

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"

#设置Session存储到Memcached

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'

CACHES = {

'default': {

'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',

'LOCATION': '192.168.43.11:11211',

　　}

}

#启用Web界面上修改密码

OPENSTACK_HYPERVISOR_FEATURES = {

　　 'can_set_mount_point': True,

　　 'can_set_password': True,

　　'requires_keypair': False,

　}

#设置时区

TIME_ZONE = "Asia/Shanghai"

#禁用自服务网络的一些高级特性

OPENSTACK_NEUTRON_NETWORK = {

　　 ...

　　 'enable_router': False,

　　 'enable_quotas': False,

　　 'enable_distributed_router': False,

　　 'enable_ha_router': False,

　　 'enable_lb': False,

　　'enable_firewall': False,

　　'enable_vpn': False,

　　 'enable_fip_topology_check': False,

}

3.启动服务

[root@linux-node2 ~]# systemctl enable httpd.service

[root@linux-node2 ~]# systemctl restart httpd.service

 

打开浏览器，输入URL：http://192.168.43.12/dashboard/auth/login/       域：Default   用户名密码：admin       域：Default   用户名密码：demo     ；如果登录不进去，首先检查时间是否同步；rabbitmq消息队列是否正常；最后查相关服务的日志的报错信息。
