? 192.168.205.7: as Chrony, DNS and YUM Source server(为了安装更快,自建yum源)
? 192.168.205.147: as DataBase, install MariaDB, RabbitMQ, Memcached
? 192.168.205.167: as controller, install keystone, placement, nova, neutron, dashboard
? 192.168.205.187: as compute node, install neutron agent and nova agent
注:所有操作系统默认停用firewalld,iptable为空,关闭selinux
? OS: centos 7 1810 with mini install for controller and SQL server
? OS: CentOS 7 1511 with mini install for compute node
? Openstack Minimal deployment for Stein
? mariadb-10.3.10
注:其它未注明均为yum 安装
? 最小化安装openstack stein最新版本
? 安装完成后各组件正常运行
? 测试成功建立实列并运行
? 通过运行实列测试基本的网络功能
1. 安装前的环境准备
2. 安装keystone
3. 安装glance镜像服务
4. 安装placement
5. 安装Nova on controller
6. 安装Nova on compute node
7. 安装Neutron on controller node
8. 安装Neutron on compute node
9. 安装dashboard
10. 验证测试
安装的准备工作很重要,因为openstack服务非常多,服务之间的依赖关系紧密,合理的规划不会导至安装出现问题,否则会出现各种的问题。
#yum install chrony
#systemctl start chronyd
#cat /etc/chrony.conf
server 192.168.205.7 iburst
#systemctl status chronyd
#chronyc sources -v #检查chrony时间是否同步,看到^*为同步,否则没有同步
#cat /etc/hosts

A dbs.flex.net 192.168.205.147 database, memcached, rabbitMQ
同进DNS也做为转发服务器为yum提像安装软件
eth0为管理和API的网络
#cat ifcfg-eth0
NAME="eth0"
DEVICE="eth0"
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.205.x
NETMASK=255.255.255.0
TYPE=Ethernet
eth1为租户tenant网络使用,不配IP,设置成none
#cat ifcfg-eth1
NAME="eth1"
DEVICE="eth1"
ONBOOT=yes
BOOTPROTO=none
eth2为外网安装yum源使用,使用nat方式,同时将dns设置为内网的dns: 192.168.205.7
#cat ifcfg-eth2
NAME="eth2"
DEVICE="eth2"
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.18.18.x
NETMASK=255.255.255.0
GATEWAY=172.18.18.2
DNS1=192.168.205.7
注:不要修改HWADDR和UUID
安装源,首先启用extras packges,我使用原cenos安装时自带的源, 也可以启用aliyun或tinghua的extras源
#ls
backup CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
backup1 CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
#yum list Centos-release-OpenStack*
…
Available Packages
centos-release-openstack-stein.noarch 1-1.el7.centos extras
centos-release-openstack-ocata.noarch 1-2.el7 extras
centos-release-openstack-pike.x86_64 1-1.el7 extras
centos-release-openstack-queens.noarch 1-2.el7.centos extras
注:安装时我们要禁用epel源
#yum install centos-release-openstack-stein
安装完成后我们看到目录中多了一些源
#ls
backup CentOS-Debuginfo.repo CentOS-QEMU-EV.repo
backup1 CentOS-fasttrack.repo CentOS-Sources.repo
CentOS-Base.repo CentOS-Media.repo CentOS-Storage-common.repo
CentOS-Ceph-Nautilus.repo CentOS-NFS-Ganesha-28.repo CentOS-Vault.repo
#cat CentOS-OpenStack-stein.repo
CentOS-OpenStack-stein.repo
…
# yum upgrade
# yum install python-openstackclient
# yum install mariadb mariadb-server python2-PyMySQL
# vi /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.205.147
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
# systemctl enable mariadb.service
# systemctl start mariadb.service
# mysql_secure_installation
Openstack的服务之间使用消息队列协调操作和状态信息,消息队列通常地运行在controller上, openstack支持几种消息队列如:rabbitMQ, Qpid, ZeroMQ. 大多的发行版都支持这些特定的消息队列,本实验我们用RabbitMQ因为大多发行版都支持它,本列中,我们的消息队列运行在dababase中
# yum install rabbitmq-server
# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service
# rabbitmqctl add_user openstack openstack123
# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
注:在vhost "/" ...中给用户 "openstack" 授权
身份识别服务验证机制使用Memcached缓存令牌,Memcached通常运行在controller上,对于生产部署,我们建议启用防火墙、身份验证和加密的组合来保护它。
# yum install memcached python-memcached
#vi /etc/sysconfi/memcached
OPTIONS="-l 127.0.0.1,::1,master" #如果你装在数据库服务器上,那么就改数据库服务器的名字, 因为hosts中已经做解析
# systemctl enable memcached.service
# systemctl start memcached.service
