OpenStack安装部署

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

(资料图片)

# systemctl stop firewalld.service# systemctl disable firewalld.service

2、关闭本地selinux防火墙

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

3、设置主机计算机名称

# hostnamectl set-hostname controller

4、本地主机名称和ip的解析

# vim /etc/hosts192.168.0.104 controller

5、安装ntp时间校准工具

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

6、安装第三方yum源

# yum -y install yum-plugin-priorities# yum -y install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-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

# yum upgrade# reboot

二、安装配置mariadb数据库

1、安装mariadb数据库

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

2、配置mariadb数据库

# cp /etc/my.cnf /etc/my.cnf.bak# rpm -ql mariadb# vim /etc/my.cnf.d/server.cnf[mysqld]bind-address = 0.0.0.0default-storage-engine = innodbinnodb_file_per_tablecollation-server = utf8_general_ciinit-connect = "SET NAMES utf8"character-set-server = utf8

3、启动mariadb数据库

# 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

# yum -y install rabbitmq-server

2、启动rabbit服务

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

3、设置rabbit服务密码

# 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

mysql -u root -pCREATE 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

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

3、配置keystone文件

# 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.Providerdriver = keystone.token.persistence.backends.sql.Token

4、创建证书和秘钥文件

# 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

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

6、启动keystone服务并开机自启动

# 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

# (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

# 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

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 adminb.Add the admin tenant and user to the admin role:# keystone user-role-add --tenant admin --user admin --role adminc.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

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.comc.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

# 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:

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

2、Create the API endpoint for the Identity service:

# 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
