OpenStack安装部署

ykuj

一、基础准备工作

部署环境：CentOS 7 64
1、关闭本地iptables防火墙并设置开机不自启动

1 2	# systemctl stop firewalld.service # systemctl disable firewalld.service

2、关闭本地selinux防火墙

1 2 3

# vim /etc/sysconfig/selinux SELINUX=disabled # setenforce 0

3、设置主机计算机名称

1	# hostnamectl set-hostname controller

4、本地主机名称和ip的解析

1 2	# vim /etc/hosts 192.168.0.104 controller

5、安装ntp时间校准工具

1 2	# yum -y install ntp # ntpdate asia.pool.ntp.org

6、安装第三方yum源

1 2 3

# yum -y install yum-plugin-priorities # yum -y install http://dl.fedoraproject.org/pub/ ... ease-7-2.noarch.rpm    # yum -y install http://rdo.fedorapeople.org/openstack-juno/rdo-release-juno.rpm

7、升级系统软件包并重新系统

1 2	# yum upgrade # reboot

二、安装配置mariadb数据库

1、安装mariadb数据库

1	# yum -y install mariadb mariadb-server MySQL-python

2、配置mariadb数据库

1 2 3 4 5 6 7 8 9 10

# cp /etc/my.cnf /etc/my.cnf.bak # rpm -ql mariadb # vim /etc/my.cnf.d/server.cnf [mysqld] bind-address = 0.0.0.0 default-storage-engine = innodb innodb_file_per_table collation-server = utf8_general_ci init-connect = 'SET NAMES utf8' character-set-server = utf8

3、启动mariadb数据库

1 2	# systemctl enable mariadb.service # systemctl start mariadb.service

三、安装消息队列服务

1、安装rabbit所需软件包

1	# yum -y install rabbitmq-server

2、启动rabbit服务

1 2	# systemctl enable rabbitmq-server.service # systemctl start rabbitmq-server.service

3、设置rabbit服务密码

1	# rabbitmqctl change_password guest rabbit

四、安装keyston用户认证组件
1、创建keystone数据库和授权用户

1 2 3 4

mysql -u root -p CREATE DATABASE keystone; GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone'; GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';

2、安装keystone组件包

1	# yum -y install openstack-utils openstack-keystone python-keystoneclient

3、配置keystone文件

1 2 3 4 5 6 7 8 9 10 11

# cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak # vim /etc/keystone/keystone.conf [DEFAULT] verbose = True [database] connection = mysql://keystone:keystone@controller/keystone [token] provider = keystone.token.providers.uuid.Provider driver = keystone.token.persistence.backends.sql.Token

4、创建证书和秘钥文件

1 2 3 4

# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone # chown -R keystone:keystone /var/log/keystone # chown -R keystone:keystone /etc/keystone/ssl # chmod -R o-rwx /etc/keystone/ssl

5、同步keystone到mariadb数据库

1	# su -s /bin/sh -c "keystone-manage db_sync" keystone

6、启动keystone服务并开机自启动

1 2	# systemctl enable openstack-keystone.service # systemctl start openstack-keystone.service

7、清除过期的令牌
默认情况下，身份服务存储在数据库中过期的令牌无限。到期令牌的积累大大增加数据库的大小，可能会降低服务的性能，特别是在资源有限的环境中。我们建议您使用cron配置一个周期性任务，清除过期的令牌时

1 2 3

# (crontab -l -u keystone 2>&1 | grep -q token_flush) ||   echo '@hourly /usr/bin/keystone-manage token_flush >/var/log/keystone/keystone-tokenflush.log 2>&1'   >> /var/spool/cron/keystone

----------------------------Create tenants,user,and roles---------------------------------

1、配置admin的token

1 2 3 4 5

# export OS_SERVICE_TOKEN=$(openssl rand -hex 10) # export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0 # echo $OS_SERVICE_TOKEN > ~/ks_admin_token # openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token  $OS_SERVICE_TOKEN # service openstack-keystone restart

2、创建tenant、user and role

1 2 3 4 5 6 7 8 9 10 11 12 13

a.Create the admin tenant、user、role # keystone tenant-create --name admin --description "Admin Tenant" # keystone user-create --name admin --pass admin --email admin@zhengyansheng.com # keystone role-create --name admin b.Add the admin tenant and user to the admin role: # keystone user-role-add --tenant admin --user admin --role admin c.By default, the dashboard limits access to users with the _member_ role. # keystone role-create --name _member_ d.Add the admin tenant and user to the _member_ role: # keystone user-role-add --tenant admin --user admin --role _member_

3、创建一个普通demo项目和用户

1 2 3 4 5 6 7 8

a.Create the demo tenant: # keystone tenant-create --name demo --description "Demo Tenant" b.Create the demo user: # keystone user-create --name demo --pass demo --email demo@zhengyansheng.com c.Add the demo tenant and user to the _member_ role: # keystone user-role-add --tenant demo --user demo --role _member_

4、创建一个service项目

1	# keystone tenant-create --name service --description "Service Tenant"

------------------------Create the service entity and API endpoint------------------------
1、Create the service entity and API endpoint | Create the service entity for the Identity service:

1	# keystone service-create --name keystone --type identity --description "OpenStack Identity"

2、Create the API endpoint for the Identity service:

1 2 3 4 5 6

# keystone endpoint-create --service-id $(keystone service-list | awk '/ identity / {print $2}') --publicurl http://controller:5000/v2.0 --internalurl http://controller:5000/v2.0 --adminurl http://controller:35357/v2.0 --region regionOne

3、查看keystone认证信息

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

4、取消临时设置的环境变量

1 2	# unset OS_SERVICE_TOKEN # unset OS_SERVICE_ENDPOINT

5、使用keystone进行用户认证

1 2 3 4

# keystone --os-tenant-name admin --os-username admin --os-password admin --os-auth-url http://controller:35357/v2.0 token-get # keystone --os-tenant-name admin --os-username admin --os-password admin --os-auth-url http://controller:35357/v2.0 tenant-list # keystone --os-tenant-name admin --os-username admin --os-password admin --os-auth-url http://controller:35357/v2.0 user-list # keystone --os-tenant-name admin --os-username admin --os-password admin --os-auth-url http://controller:35357/v2.0 role-list

6、使用普通用户demo认证测试

1 2 3

# keystone --os-tenant-name demo --os-username demo --os-password demo --os-auth-url http://controller:35357/v2.0 token-get # keystone --os-tenant-name demo --os-username demo --os-password demo --os-auth-url http://controller:35357/v2.0 user-list You are not authorized to perform the requested action: admin_required (HTTP 403)

7、客户端cli命令行脚本

1 2 3 4 5

# vim ~/admin-openrc.sh export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=admin export OS_AUTH_URL=http://controller:35357/v2.0

1 2 3 4 5

# vim ~/demo-openrc.sh export OS_TENANT_NAME=demo export OS_USERNAME=demo export OS_PASSWORD=demo export OS_AUTH_URL=http://controller:5000/v2.0

1	# source admin-openrc.sh

8、测试如果取消环境变量，通过keystone仍然能够认证通过说明keystone是配置成功的
