一、虚拟机配置信息
1.1 资源规划
主机名 | CPU | 内存 | 硬盘 | 网卡 | 系统 |
CT | 2核2线程-虚拟化开启 | 8G | 300+300G | NAT:20.0.0.11 VM:192.168.100.11 | CentOS7.6(最小安装) |
C1 | 2核2线程-虚拟化开启 | 8G | 300+300G | NAT:20.0.0.11 VM:192.168.100.11 | CentOS7.6(最小安装) |
C2 | 2核2线程-虚拟化开启 | 8G | 300+300G | NAT:20.0.0.11 VM:192.168.100.11 | CentOS7.6(最小安装) |
1.2 部署思路
1.配置操作系统+OpenStack运行环境
2.配置OpenStack平台基础服务(rabbitmq、mariadb、memcache、Apache)
3.配置OpenStack keystone组件
4.配置OpenStack Glance组件
5.配置placement服务
6.配置OpenStack Nova组件
7.配置OpenStack Neutron组件
8.配置OpenStack dashboard组件
9.配置OpenStack Cinder组件
10.常用云主机操作
二、基础环境配置
2.1 所有节点基础配置项
#主机名
[root@server ~]# hostnamectl set-hostname ct
[root@server ~]# bash
#防火墙、核心防护
[root@ct ~]# systemctl stop firewalld
[root@ct ~]# systemctl disable firewalld
[root@ct ~]# setenforce 0
[root@ct ~]# vim /etc/sysconfig/selinux
SELINUX=disabled
#基础环境依赖包
yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre pcre-devel expat-devel cmake bzip2
yum -y install centos-release-openstack-train python-openstackclient openstack-selinux openstack-utils
#时间同步+周期性计划任务
#配置网卡
vi /etc/sysconfig/network-scripts/ifcfg-ens33
BOOTPROTO=static
IPV4_ROUTE_METRIC=90 ###调由优先级,NAT网卡优先
ONBOOT=yes
IPADDR=192.168.226.150
NETMASK=255.255.255.0
GATEWAY=192.168.226.2
cp /etc/sysconfig/network-scripts/ifcfg-ens33 /etc/sysconfig/network-scripts/ifcfg-ens37
vi /etc/sysconfig/network-scripts/ifcfg-ens37
BOOTPROTO=static
ONBOOT=yes
IPADDR=192.168.100.11
NETMASK=255.255.255.0
#配置DNS(所有节点)
[root@ct ~]# vim /etc/resolv.conf
nameserver 114.114.114.114
systemctl restart network #重启网卡
#配置Hosts
[root@ct ~]# vi /etc/hosts
192.168.100.11 ct
192.168.100.12 c1
192.168.100.13 c2
PS:以上为局域网IP
2.2 三台节点做免交互
#非对称密钥
[root@ct ~]# ssh-keygen -t rsa
[root@ct ~]# ssh-copy-id ct
[root@ct ~]# ssh-copy-id c1
[root@ct ~]# ssh-copy-id c2
2.3 控制节点ct时间同步配置
[root@ct ~]# yum install chrony -y
[root@ct ~]# vim /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#server 0.centos.pool.ntp.org iburst #注释掉以下几行
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ntp6.aliyun.com iburst #添加阿里云时间同步
allow 192.168.100.0/24 #允许100网段同步自己的时间
[root@ct ~]# systemctl enable chronyd
[root@ct ~]# systemctl restart chronyd
#主机c1,c2
[root@c1 ~]# yum install chrony -y
[root@c1 ~]# vi /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#server 0.centos.pool.ntp.org iburst #注释这几行
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst
server ct iburst #同步主机ct
[root@c1 ~]# systemctl enable chronyd
[root@c1 ~]# systemctl restart chronyd
#使用 chronyc sources 命令查询时间同步信息
[root@ct ~]# chronyc sources
210 Number of sources = 1

2.4 设置周期性任务
[root@ct ~]# crontab -e
*/30 * * * * /usr/bin/chronyc sources >> /var/log/chronyc.log
#OpenStack 的 train 版本仓库源安装 包,同时安装 OpenStack 客户端和 openstack-selinux 安装包
三、配置控制端服务
3.1 安装、配置MariaDB
[root@ct ~]# yum -y install mariadb mariadb-server python2-PyMySQL
#此包用于openstack的控制端连接mysql所需要的模块,如果不安装,则无法连接数据库;此包只安装在控制端
[root@ct ~]# yum -y install libibverbs
#添加MySQL子配置文件,增加如下内容
[root@ct ~]# vim /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.100.11
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
#开机自启动、开启服务
[root@ct my.cnf.d]# systemctl enable mariadb
[root@ct my.cnf.d]# systemctl start mariadb
#执行MariaDB 安全配置脚本
[root@ct my.cnf.d]# mysql_secure_installation
Enter current password for root (enter for none): #回车
OK, successfully used password, moving on...
Set root password? [Y/n] Y
Remove anonymous users? [Y/n] Y
... Success!
Disallow root login remotely? [Y/n] N
... skipping.
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y
3.2 安装RabbitMQ
#所有创建虚拟机的指令,控制端都会发送到rabbitmq,node节点监听rabbitmq
[root@ct ~]# yum -y install rabbitmq-server
#配置服务,启动RabbitMQ服务,并设置其开机启动。
[root@ct ~]# systemctl enable rabbitmq-server.service
[root@ct ~]# systemctl start rabbitmq-server.service
#创建消息队列用户,用于controler和node节点连接rabbitmq的认证
[root@ct ~]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack"
#配置openstack用户的操作权限(正则,配置读写权限)
[root@ct ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/"
#可查看25672和5672 两个端口(5672是Rabbitmq默认端口,25672是Rabbit的测试工具CLI的端口)
#查看rabbitmq插件列表
[root@ct ~]# rabbitmq-plugins list
#开启rabbitmq的web管理界面的插件,端口为15672
[root@ct ~]# rabbitmq-plugins enable rabbitmq_management
#检查端口(25672 5672 15672)
[root@ct my.cnf.d]# ss -natp | grep 5672
LISTEN 0 128 *:25672 *:* users:(("beam.smp",pid=24596,fd=46))
LISTEN 0 128 :::5672 :::* users:(("beam.smp",pid=24596,fd=55))
#可访问20.0.0.11:15672
默认账号密码均为guest
3.3 安装memcached
安装memcached是用于存储session信息;服务身份验证机制使用Memcached来缓存令牌 在登录openstack的dashboard时,会产生一些session信息,这些session信息会存放到memcached中
#安装Memcached
[root@ct ~]# yum install -y memcached python-memcached
#python-*模块在OpenStack中起到连接数据库的作用
#修改Memcached配置文件
[root@ct ~]# cat /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,ct"
[root@ct ~]# systemctl enable memcached
[root@ct ~]# systemctl start memcached
[root@ct ~]# netstat -nautp | grep 11211
3.4 安装etcd
[root@ct ~]# yum -y install etcd
#修改etcd配置文件
[root@ct ~]# cd /etc/etcd/
[root@ct etcd]# ls
etcd.conf
[root@ct etcd]# vim etcd.conf
#数据目录位置
#监听其他etcd member的url(2380端口,集群之间通讯,域名为无效值)
#对外提供服务的地址(2379端口,集群内部的通讯端口)
#集群中节点标识(名称)
#该节点成员的URL地址,2380端口:用于集群之间通讯。
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.100.11:2380"
ETCD_LISTEN_CLIENT_URLS="http://192.168.100.11:2379"
ETCD_NAME="ct"
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.100.11:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://192.168.100.11:2379"
ETCD_INITIAL_CLUSTER="ct=http://192.168.100.11:2380"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01" #集群唯一标识
ETCD_INITIAL_CLUSTER_STATE="new" #初始集群状态,new为静态,若为existing,则表示此ETCD服务将尝试加入已有的集群若为DNS,则表示此集群将作为被加入的对象
#开机自启动、开启服务,检测端口
[root@ct ~]# systemctl enable etcd.service
[root@ct ~]# systemctl start etcd.service
[root@ct ~]# netstat -anutp |grep 2379
[root@ct ~]# netstat -anutp |grep 2380
