+-------------+--------------+---------+-----------+------------------------------+------------------+------------------+

1、网络环境

主机	IP
controller	10.0.0.51
compute1	10.0.0.61

修改hosts文件
cat /etc/hosts
10.0.0.51 controller
10.0.0.61 compute1

关闭selinux、firewalld

cat env_set.sh
#!/bin/bashsystemctl  stop firewalld
systemctl  disable firewalldsetenforce 0
sed  -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
yum install -y wget

配置阿里yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

手动配置阿里源

[centotack-rocky]
name=openstack-rocky
baseurl=https://mirrors.aliyun.com/centos/7/cloud/x86_64/openstack-rocky/
enabled=1
gpgcheck=0[qume-kvm]
name=qemu-kvm
baseurl= https://mirrors.aliyun.com/centos/7/virt/x86_64/kvm-common/
enabled=1
gpgcheck=0

安装openstack客户端和openstack-selinux
yum install python-openstackclient openstack-selinux -y

2、同步时间

安装相关软件
yum install chrony vim net-tools lsof -y

#controller节点
allow 10.0.0.0/24

#其他节点
server 10.0.0.51 iburst
重启服务

systemctl enable chronyd.service
systemctl start chronyd.service

3、部署mariadb数据库

数据库节点

yum install mariadb mariadb-server python2-PyMySQL -y

修改数据库配置文件 /etc/my.cnf

bind-address = 10.0.0.51
default-storage-engine = innodb
innodb_file_per_table       #innodb使用独立的表结构
max_connections = 4096     #最大的连接数
collation-server = utf8_general_ci #使用utf-8字符集
character-set-server = utf8

启动数据库

systemctl enable mariadb
systemctl start mariadb

数据库安全初始化

mysql_secure_installation#回车 n y y y y

4、消息队列RabbitMQ

安装rabbit

yum install rabbitmq-server
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

#添加openstack用户，设置密码
rabbitmqctl add_user openstack RABBIT_PASSCreating user "openstack" ...
#给openstack用户配置写和读权限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"Setting permissions for user "openstack" in vhost "/" ...

Rabbitmq默认会开启25672和5672端口
验证：

# netstat -antplu|grep 5672
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      11226/beam.smp
tcp6       0      0 :::5672                 :::*                    LISTEN      11226/beam.smp

开启插件，监控. 端口：15672

rabbitmq-plugins enable rabbitmq_management

# netstat -antplu|grep 5672
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      11226/beam.smp
tcp        0      0 0.0.0.0:15672           0.0.0.0:*               LISTEN      11226/beam.smp
tcp6       0      0 :::5672                 :::*                    LISTEN      11226/beam.smp

5、配置memcached

 yum install -y memcached python-memcached #默认监听需要修改sed -i 's/127.0.0.1/10.0.0.51/g' /etc/sysconfig/memcachedsystemctl  restart memcached.service

验证：

# netstat -anpl|grep 11211
tcp        0      0 10.0.0.51:11211         0.0.0.0:*               LISTEN      12152/memcached

6、openstack服务安装的通用步骤：

1.创库授权
2.在keystone创建用户，关联角色
3.在keystone上注册服务，注册api
4.安装服务相关的软件包
5.修改配置文件        数据库的连接信息        rabbitmq的连接信息       keystone认证授权信息
6.同步数据库，创建表
7.启动服务

二、keystone服务的安装

1、创库授权

create DATABASE keystone;
GRANT ALL PRIVILEGES on keystone.* to 'keystone'@'localhost'  identified by 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'KEYSTONE_DBPASS';

2、安装keystone相关软件包

yum install -y openstack-keystone httpd mod_wsgi

修改配置文件

cp /etc/keystone/keystone.conf{,.back}
grep -Ev '^$|^#' /etc/keystone/keystone.conf.back > /etc/keystone/keystone.conf
cat /etc/keystone/keystone.conf
[DEFAULT]
admin_token = ADMIN_TOKENconnection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone[token]
provider = fernet#同步数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone#初始化fernet
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
#验证
ll /etc/keystone

3、配置httpd

echo "ServerName controller" >>/etc/httpd/conf/httpd.conf
cat /etc/httpd/conf.d/wsgi-keystone.conf
Listen 5000
Listen 35357<VirtualHost *:5000>WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}WSGIProcessGroup keystone-publicWSGIScriptAlias / /usr/bin/keystone-wsgi-publicWSGIApplicationGroup %{GLOBAL}WSGIPassAuthorization OnErrorLogFormat "%{cu}t %M"ErrorLog /var/log/httpd/keystone-error.logCustomLog /var/log/httpd/keystone-access.log combined<Directory /usr/bin>Require all granted</Directory>
</VirtualHost><VirtualHost *:35357>WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}WSGIProcessGroup keystone-adminWSGIScriptAlias / /usr/bin/keystone-wsgi-adminWSGIApplicationGroup %{GLOBAL}WSGIPassAuthorization OnErrorLogFormat "%{cu}t %M"ErrorLog /var/log/httpd/keystone-error.logCustomLog /var/log/httpd/keystone-access.log combined<Directory /usr/bin>Require all granted</Directory>
</VirtualHost>

重启
systemctl enable httpd.service
systemctl restart httpd.service

4、创建服务和注册api：

#配置认证令牌：
export OS_TOKEN=ADMIN_TOKEN
#配置端点URL：
export OS_URL=http://controller:35357/v3
#配置认证 API 版本：
export OS_IDENTITY_API_VERSION=3openstack service create \--name keystone --description "OpenStack Identity" identityopenstack endpoint create --region RegionOne \identity public http://controller:5000/v3openstack endpoint create --region RegionOne \identity internal http://controller:5000/v3openstack endpoint create --region RegionOne \identity admin http://controller:35357/v3

创建域、项目、用户、角色

openstack domain create --description "Default Domain" defaultopenstack project create --domain default \--description "Admin Project" adminopenstack user create --domain default \--password ADMIN_PASS adminopenstack role create adminopenstack role add --project admin --user admin adminopenstack project create --domain default \--description "Service Project" service

退出bash
给定初始变量

# cat admin-openrc
export OS_AUTH_URL=http://controller:35357/v3
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_IMAGE_API_VERSION=2
export OS_IDENTITY_API_VERSION=3
export OS_PASSWORD=ADMIN_PASS
source admin-openrcecho 'source admin-openrc'  >> /etc/bashrc

验证：

openstack token issue
openstack user list
openstack service list
openstack endpoint list

三、镜像服务 glance

1、创库授权

CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \IDENTIFIED BY 'GLANCE_DBPASS';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \IDENTIFIED BY 'GLANCE_DBPASS';

2、在keystone创建用户，关联角色

openstack user create --domain default --password GLANCE_PASS glance
openstack role add --project service --user glance admin

3、在keystone上注册服务，注册api

openstack endpoint create --region RegionOne \image public http://controller:9292
openstack endpoint create --region RegionOne \image internal http://controller:9292
openstack endpoint create --region RegionOne \image admin http://controller:9292

4、安装服务相关的软件包

yum install openstack-glance -y

5、修改配置文件

cp /etc/glance/glance-api.conf{,.back}
grep -Ev '^$|#' /etc/glance/glance-api.conf.back > /etc/glance/glance-api.confcp /etc/glance/glance-registry.conf{,.back}
grep -Ev '^$|#'  /etc/glance/glance-registry.conf.back >/etc/glance/glance-registry.conf# cat /etc/glance/glance-api.conf

6、同步数据库，创建表

# su -s /bin/sh -c "glance-manage db_sync" glance

启动镜像服务、配置他们随机启动：

 systemctl enable openstack-glance-api.service \openstack-glance-registry.servicesystemctl start openstack-glance-api.service \openstack-glance-registry.service

四、nova的安装

1、创库授权

CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \IDENTIFIED BY 'NOVA_DBPASS';

对域的修改

vim /etc/httpd/conf.d/openstack-dashboard.confWSGIApplicationGroup %{GLOBAL}systemctl  restart httpd

七、创建一个实例

1、创建网路

neutron net-create --shared --provider:physical_network provider \--provider:network_type flat ouzhenetneutron subnet-create --name ouzhe1 \--allocation-pool start=10.0.0.101,end=10.0.0.200 \--dns-nameserver 114.114.114.114 --gateway 10.0.0.2 \ouzhenet 10.0.0.0/24

2、创建m1.nano规格的主机

openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

3、生成和添加秘钥对

ssh-keygen -q -N "" -f ~/.ssh/id_rsa
openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

4、增加安全组规则

openstack security group rule create --proto icmp default
openstack security group rule create --proto tcp --dst-port 22 default

5、创建主机

neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.
+--------------------------------------+----------+----------------------------------+--------------------------------------------------+

验证创建的虚拟机

验证是否有IP地址，能否上外网

搭建时的一些下错误

Host ‘compute1’ is not mapped to any cell

解决方案

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
