先创建两台虚拟机内存放大一些,实际用的内存不会那么高
1.controller节点硬件配置
镜像我这里使用1804的 (注意:要添加一个仅主机模式的网络适配器)
2.编辑compute硬件
添加硬盘
三次下一步默认设置到这里
(注意这里是两张网卡,一张NET,一张仅主机)
开机
1.修改网路配置
controller跟compute节点
(根据自己ip a查看网卡名字进行修改)
vi /etc/sysconfig/network-scripts/ifcfg-ens33
在最后面添加以下信息,DNS1为网关ip(我这里controller节点的ip为192.168.200.10,compute节点为192.168.200.20)
- IPADDR=192.168.200.10
- NETMASK=255.255.255.0
- GATEWAY=192.168.200.2
- DNS1=192.168.200.2
ip改为固定的
第二张网卡只需要将这里改为yes,也可以不改
重启网络
systemctl restart network
尝试ping外网
2.关闭防火墙
(controller节点加compute节点)
- systemctl stop firewalld
-
- systemctl disable firewalld
3.更改主机名
(controller节点加compute节点)
- hostnamectl set-hostname controller
- bash
4.映射
controller节点
vi /etc/hosts
在下面添加两个节点的ip跟名字,(ip根据自己的改,名字跟下面的一样)
5.进行免密操作
ssh-keygen
(一直回车)
ssh-copy-id compute
yes
密码(计算节点的开机密码)
scp /etc/hosts compute:/etc/hosts
6.修改seliunx
vi /etc/selinux/config
这个改成图片中的模式
7.yum源配置
(controller节点加compute节点)
mv /etc/yum.repos.d/* /media/
vi /etc/yum.repos.d/openstack.repo
- [centos-base]
- name=centos-base
- baseurl=https://mirrors.163.com/centos/$releasever/os/$basearch
- gpgcheck=0
- enabled=1
-
- [centos-extras]
- name=centos-extras
- baseurl=https://mirrors.163.com/centos/$releasever/extras/$basearch
- gpgcheck=0
- enabled=1
-
- [openstack]
- name=openstack rocky
- baseurl=https://mirrors.163.com/centos/$releasever/cloud/$basearch/openstack-rocky
- gpgcheck=0
- enabled=1
-
- [virt]
- name=virt
- baseurl=https://mirrors.163.com/centos/$releasever/virt/$basearch/kvm-common/
- gpgcheck=0
- enabled=1
yum repolist
结果为13404多个包
注意节点信息
yum install -y chrony
controller节点
(建议下载一个vim(这个可以更直观看文档里面的区别)效果与vi命令大同小异,但是更直观。后面的vi命令本教程统一用vim)
下载vim命令(可以选择不下)
yum install -y vim
vim /etc/chrony.conf
- systemctl restart chronyd
-
- systemctl enable chronyd
测试
compute节点
在最后面添加
server 192.168.200.10 iburst
重启服务
- systemctl restart chronyd
-
- systemctl enable chronyd
chronyc sources
(controller节点加compute节点)
- yum install -y python-openstackclient
-
- yum install -y openstack-selinux
只需要在controller节点安装
yum install -y mariadb mariadb-server python2-PyMYSQL
vim /etc/my.cnf.d/openstack.cnf
在里面添加(ip改为自己controller节点的ip)
- [mysqld]
- bind-address = 192.168.200.10
- default-storage-engine = innodb
- innodb_file_per_table = on
- max_connections = 4096
- collation-server = utf8_general_ci
- character-set-server = utf8
(开机自启服务)
systemctl enable mariadb.service
(启动服务)
systemctl start mariadb.service
进行安全设置
mysql_secure_installation
Enter current password for root (enter for none):回车
Set root password? [Y/n] y
New password:输入密码(一般为000000)
Re-enter new password:再次输入密码
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y
只在controller节点安装rabbitmq
yum install -y rabbitmq-server
启动服务
- systemctl enable rabbitmq-server.service
- systemctl start rabbitmq-server.service
增加用户和授权
rabbitmqctl add_user openstack 000000
成功是显示以下,如果报错,先检查另一台虚拟机是否改名成controller,
如果报错;两个节点都进行以下操作
hostnamectl set-hostname controller bash操作完上面这步后,两个节点都打
reboot
这是让两个节点重启,让环境生效,然后重新连接第三方输入密码后重新打
rabbitmqctl add_user openstack 000000
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
成功如下
只在controller节点安装
yum -y install memcached python-memcached
修改配置
vim /etc/sysconfig/memcached
在1后面添加,controller
启动服务
- systemctl enable memcached.service
- systemctl start memcached.service
到此完成基础服务和软件安装,建议两台虚拟机保存快照,自己备注好
该任务在controller节点完成,但请确保compute节点为开机状态
(1)数据库的创建
mysql -u root -p000000
命令如下
CREATE DATABASE keystone;
- GRANT ALL PRIVILEGES ON keystone.* \
- TO 'keystone'@'localhost' IDENTIFIED BY '000000';
- GRANT ALL PRIVILEGES ON keystone.* \
- TO 'keystone'@'%' IDENTIFIED BY '000000';
打完成功后如上图所示
exit 退出
(2)安装keystone
yum install -y openstack-keystone httpd mod_wsgi
(3)修改配置
vim /etc/keystone/keystone.conf
(建议下载一个vim(这个可以更直观看文档里面的区别)效果与vi命令大同小异,但是更直观。后面的vi命令本教程统一用vim)
下载vim命令(可以选择不下)
yum install -y vim
在对应下面添加,得找到对应的 [] 下添加
例如:
[database]
connection = mysql+pymysql://keystone:000000@controller/keystone
[token]
provider = fernet
查找技巧:在命令模式下(也就是保存退出时用到的Esc这个按键),:/ 后面添加要查找的关键字符,如 :/database 后按回车进行查找第一个,如果要继续往下查找,按n键往下查找,按Shift+n键为往上查找
(不要将[database]中的[]符号加入到查找里面)
[database]
connection = mysql+pymysql://keystone:000000@controller/keystone
[token]
provider = fernet
(4)初始化数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone
(5)初始化keystone
- keystone-manage fernet_setup --keystone-user keystone \
- --keystone-group keystone
- keystone-manage credential_setup --keystone-user keystone \
- --keystone-group keystone
- keystone-manage bootstrap --bootstrap-password 000000 \
- --bootstrap-admin-url http://controller:5000/v3/ \
- --bootstrap-internal-url http://controller:5000/v3/ \
- --bootstrap-public-url http://controller:5000/v3/ \
- --bootstrap-region-id RegionOne
(6)修改httpd的配置
vim /etc/httpd/conf/httpd.conf
可以通过上面介绍的查找关键字,找关键字ServerName,将前面注释符#删掉
改成
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
(7)启动httpd服务
- systemctl enable httpd.service
- systemctl start httpd.service
(8)设置环境变量
vi ~/.bashrc
在最下面添加
- export OS_USERNAME=admin
- export OS_PASSWORD=000000
- export OS_PROJECT_NAME=admin
- export OS_USER_DOMAIN_NAME=Default
- export OS_PROJECT_DOMAIN_NAME=Default
- export OS_AUTH_URL=http://controller:5000/v3
- export OS_IDENTITY_API_VERSION=3
- export OS_IMAGE_API_VERSION=2
保存退出
source ~/.bashrc
这个命令为更新上面的配置,不用重新登录,省下来的三分钟你能干嘛,懂的都懂
(9)创建一个项目
openstack project create --domain default --description "Service Project" service
成功创建后显示以下
要是你还不确信,继续执行
openstack project list
不就跟书本上一样了嘛,舒服没,犟驴 o . O
.
(1)安装bash-completion软件
yum -y install bash-completion
(2)修改~/.bashrc文件,在最后加上
vi ~/.bashrc
source <(openstack complete --shell bash)
再更新一下配置
source ~/.bashrc
完成后建议保存一下快照
书本例3-2
token=$(openstack token issue -f value -c id)
echo $token
完成显示
curl -s http://controller:5000/v3/projects -H "Content-type: application/json" -H "X-Auth-Token: $token" | python -mjson.tool|grep name
(1)创建数据库
mysql -u root -p000000
CREATE DATABASE glance;
- GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
- IDENTIFIED BY '000000';
- GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
- IDENTIFIED BY '000000';
查看是否成功创建好数据库
show databases;
exit退出
(2)创建用户、角色和服务
openstack user create --domain default --password-prompt glance
输入两次密码
openstack role add --project service --user glance admin
openstack service create --name glance --description "OpenStack Image" image
结果
(3)创建Endpoint
1
- openstack endpoint create --region RegionOne \
- image public http://controller:9292
2
- openstack endpoint create --region RegionOne \
- image internal http://controller:9292
3
- openstack endpoint create --region RegionOne \
- image admin http://controller:9292
(4)安装软件
yum -y install openstack-glance
(5)修改配置
修改/etc/glance/glance-api.conf
vim /etc/glance/glance-api.conf
通过查找关键字,在下面添加以下配置(每次添加后再次查找,先按Esc进入命令模式后打:/ )
(查找【】中间的单词,不要添加【】)
(建议下载一个vim(这个可以更直观看文档里面的区别)效果与vi命令大同小异,但是更直观。后面的vi命令本教程统一用vim)
下载vim命令(可以选择不下)
yum install -y vim
在对应下面添加,得找到对应的 [] 下添加
[database]
connection = mysql+pymysql://keystone:000000@controller/keystone
[token]
provider = fernet
查找技巧:在命令模式下(也就是保存退出时用到的Esc这个按键),:/ 后面添加要查找的关键字符,如 :/database 后按回车进行查找第一个,如果要继续往下查找,按n键往下查找,按Shift+n键为往上查找
(不要将[database]中的[]符号加入到查找里面)

如图所示
[paste_deploy]
flavor = keystone
[glance_store]
- stores = file,http
- default_store = file
- filesystem_store_datadir = /var/lib/glance/images/
修改/etc/glance/glance-registry.conf
vim /etc/glance/glance-registry.conf
跟上面操作一样,查找后添加进去
[database]
connection = mysql+pymysql://glance:000000@controller/glance
[keystone_authtoken]
- www_authenticate_uri = http://controller:5000
- auth_url = http://controller:5000

当创建的云主机操控台无法访问到controller节点的ip时
可以点右边字体跳转更详细教程openstack控制台显示找不到controller节点ip
(如果云平台已经创建有网络这些东西,先删除同名的)
1.查看有无名为cirros的镜像
openstack image list
如果没有cirros镜像,则创建cirros镜像:(cirros-0.3.4-x86_64-disk.img这个镜像放在mnt目录)
glance image-create --disk-format qcow2 --container-format bare --name cirros </mnt/cirros-0.3.4-x86_64-disk.img
2.创建实例类型
openstack flavor create --id 2 --ram 1024 --disk 1 --vcpus 1 f2
3.创建网络
(1)创建外网
- openstack network create --project admin --provider-physical-network provider \
- --provider-network-type flat --external ext-net
(2)创建内网
openstack network create --project admin --provider-network-type vxlan --internal int-net
(3)创建外网子网(ip网关用第二张网卡的ip网关)
openstack subnet create --project admin --dhcp --gateway 192.168.100.1 --subnet-range 192.168.100.0/24 --network ext-net --allocation-pool start=192.168.100.100,end=192.168.100.200 ext-subnet
(4)创建内网子网(这里ip直接用这个)
openstack subnet create --project admin --dhcp --gateway 10.1.1.1 --subnet-range 10.1.1.0/24 --network int-net int-subnet
4.创建路由器
(1)创建路由器
openstack router create --project admin router1
(2)设置外网网关
openstack router set --external-gateway ext-net --enable-snat router1
(3)连接内网
openstack router add subnet router1 int-subnet
5.创建安全组与规则
(1)创建安全组
openstack security group create --project admin sg-1
(2)创建安全组规则
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol icmp --ingress sg-1
-
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol icmp --egress sg-1
-
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol tcp --dst-port 1:65535 --ingress sg-1
-
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol tcp --dst-port 1:65535 --egress sg-1
-
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol udp --dst-port 1:65535 --ingress sg-1
-
- openstack security group rule create --remote-ip 0.0.0.0/0 --ethertype IPv4 \
- --protocol udp --dst-port 1:65535 --egress sg-1
6.创建实例
- openstack server create --image cirros --flavor f2 --security-group sg-1 \
- --availability-zone nova --network int-net vm01
7.绑定浮动IP
(1)生成浮动IP
openstack floating ip create ext-net
(2)绑定浮动IP
openstack floating ip list
openstack server add floating ip vm01 192.168.30.104
知道爱你 没有结局
痴心妄想你会给我甜蜜
有心无力遥不可及
一切幻想写入了歌里
