openstack-T版环境部署
一.实验准备
1.虚拟机资源准备
(1)控制节点ct
CPU:双核双线程-CPU虚拟化开启
内存:8G
硬盘:300G
双网卡:VM1-(局域网)192.168.100.11 NAT-192.168.206.11
操作系统:Centos 7.6(1810)-最小化安装
(2)计算节点c1
CPU:双核双线程-CPU虚拟化开启
内存:8G
硬盘:300G
双网卡:VM1(局域网)-192.168.100.22 NAT-192.168.206.22
操作系统:Centos 7.6(1810)-最小化安装
(3)计算节点c2
CPU:双核双线程-CPU虚拟化开启
内存:8G
硬盘:300G
双网卡:VM1(局域网)-192.168.100.33 NAT-192.168.206.33
操作系统:Centos 7.6(1810)-最小化安装
2.基础环境配置
(1)修改主机名
3个节点
[root@localhost ~]# hostnamectl set-hostname ct
[root@ct ~]# su
[root@localhost ~]# hostnamectl set-hostname c1
[root@c1 ~]# su
[root@localhost ~]# hostnamectl set-hostname c2
[root@c2 ~]# su
(2)关闭防火墙、核心防护
3个节点
[root@ct ~]# systemctl stop firewalld
[root@ct ~]# systemctl disable firewalld
[root@ct ~]# setenforce 0
(3)设置网卡,每个节点添加网卡
说明:
每个节点双网卡,分别选择nat和vmnet1
IPV4_ROUTE_METRIC=90 #调优先级,设置NAT网卡优先
①ct控制节点
配置ens33网卡
配置ens37网卡
重启network,ifconfig查看网卡信息
② c1计算节点
配置ens33网卡
配置ens37网卡
重启network,ifconfig查看网卡信息
③ c2计算节点
配置ens33网卡
配置ens37网卡
重启network,ifconfig查看网卡信息
(4)配置主机映射,配置局域网ip
3个节点
[root@ct ~]# vi /etc/hosts
192.168.100.11 ct
192.168.100.22 c1
192.168.100.33 c2
(5)设置免交互
3个节点
[root@ct ~]# ssh-keygen -t rsa
[root@ct ~]# ssh-copy-id ct
[root@ct ~]# ssh-copy-id c1
[root@ct ~]# ssh-copy-id c2
(6)安装基础环境依赖包
3个节点均安装
yum -y install net-tools bash-completion vim gcc gcc-c++ make pcre pcre-devel expat-devel cmake bzip2 lrzsz
EXPAT C语言发开库
#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
yum -y install centos-release-openstack-train python-openstackclient openstack-selinux openstack-utils
(7)设置时间同步、周期性计划
ct ->同步阿里云时钟服务器
c1、c2 -> 同步ct
① ct节点
[root@ct ~]# yum install chrony -y
[root@ct ~]# vim /etc/chrony.conf
server 0.centos.pool.ntp.org iburst #注释掉
server 1.centos.pool.ntp.org iburst #注释掉
server 2.centos.pool.ntp.org iburst #注释掉
server 3.centos.pool.ntp.org iburst #注释掉
server ntp6.aliyun.com iburst #配置阿里云时钟服务器源
allow 192.168.100.0/24 #允许192.168.100.0/24网段的主机来同步时钟服务
② c1和c2节点
[root@c1 ~]# yum install chrony -y
[root@c1 ~]# vi /etc/chrony.conf
server 0.centos.pool.ntp.org iburst #注释掉
server 1.centos.pool.ntp.org iburst #注释掉
server 2.centos.pool.ntp.org iburst #注释掉
server 3.centos.pool.ntp.org iburst #注释掉
server ct iburst #配置阿里云时钟服务器源
二.系统环境配置(控制节点ct配置服务)
1.安装、配置MariaDB
(1)安装
[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
(2)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 #控制节点局域网地址
default-storage-engine = innodb #默认存储引擎
innodb_file_per_table = on #每张表独立表空间文件
max_connections = 4096 #最大连接数
collation-server = utf8_general_ci #默认字符集
character-set-server = utf8
(3)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
(4)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 #是否不允许root用户远程登陆
... skipping.
Remove test database and access to it? [Y/n] Y #是否删除test测试库
Reload privilege tables now? [Y/n] Y
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
(1)下载安装RabbitMQ服务
[root@ct ~]# yum -y install rabbitmq-server
(2)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
(3)创建消息队列用户,用于controler和 计算节点连接rabbitmq的认证(关联)
[root@ct ~]# rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack"
(4)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)
(5)查看rabbitmq插件列表
[root@ct ~]# rabbitmq-plugins list
Configured: E = explicitly enabled; e = implicitly enabled
| Status: * = running on rabbit@localhost
|/
[ ] amqp_client 3.6.16
[ ] cowboy 1.0.4
[ ] cowlib 1.0.2

[ ] rabbitmq_web_stomp 3.6.16
[ ] rabbitmq_web_stomp_examples 3.6.16
[ ] sockjs 0.3.4
(6)开启rabbitmq的web管理界面的插件,端口为15672
[root@ct ~]# rabbitmq-plugins enable
Error: Not enough arguments for 'enable'
[root@ct ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
amqp_client
cowlib
cowboy
rabbitmq_web_dispatch
rabbitmq_management_agent
rabbitmq_management
Applying plugin configuration to rabbit@localhost... started 6 plugins.
[root@ct ~]# ss -natp | grep 5672
LISTEN 0 128 *:25672 *:* users:(("beam.smp",pid=21123,fd=46))
LISTEN 0 128 *:15672 *:* users:(("beam.smp",pid=21123,fd=57))
TIME-WAIT 0 0 127.0.0.1:52091 127.0.0.1:25672
LISTEN 0 128 :::5672 :::* users:(("beam.smp",pid=21123,fd=55))
(7)访问网页
浏览器访问192.168.206.11:15672
用户名密码guest登录
3.安装memcached
memcached作用
安装memcached是用于存储session信息;服务身份验证机制(keystone)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
(1)安装
[root@ct ~]# yum install -y memcached python-memcached
(2)修改Memcached配置文件
[root@ct ~]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 127.0.0.1,::1,ct"
(3)设置开机自启,重启服务,查看端口
[root@ct ~]# systemctl enable memcached
Created symlink from /etc/systemd/system/multi-user.target.wants/memcached.service to /usr/lib/systemd/system/memcached.service.
[root@ct ~]# systemctl start memcached
[root@ct ~]# netstat -nautp | grep 11211
tcp 0 0 192.168.100.11:11211 0.0.0.0:* LISTEN 23935/memcached
tcp 0 0 127.0.0.1:11211 0.0.0.0:* LISTEN 23935/memcached
tcp6 0 0 ::1:11211 :::* LISTEN 23935/memcached
4.安装etcd
(1)下载安装etcd
[root@ct ~]# yum -y install etcd
(2)修改etcd配置文件
[root@ct ~]# cd /etc/etcd/
[root@ct etcd]# ls
etcd.conf
[root@ct etcd]# vim etcd.conf
(3)开机自启动、开启服务,检测端口
[root@ct etcd]# systemctl enable etcd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/etcd.service to /usr/lib/systemd/system/etcd.service.
[root@ct etcd]# systemctl start etcd.service
[root@ct etcd]# netstat -anutp |grep 2379
tcp 0 0 192.168.100.11:2379 0.0.0.0:* LISTEN 25010/etcd
tcp 0 0 192.168.100.11:2379 192.168.100.11:48718 ESTABLISHED 25010/etcd
tcp 0 0 192.168.100.11:48718 192.168.100.11:2379 ESTABLISHED 25010/etcd
[root@ct etcd]# netstat -anutp |grep 2380
tcp 0 0 192.168.100.11:2380 0.0.0.0:* LISTEN 25010/etcd
[root@ct etcd]#
