openstack搭建教程_openstack平台搭建步骤 OpenStack安装部署一、基础准备工作部署环境：CentOS 7 641、关闭本地iptables防火墙并设置开机不自启动# systemctl stop firewalld.service# systemctl disable firewalld.service2、关闭本地selinux防火墙# vim /etc/sysconfig/selinux SELINUX=disabled# setenforce 03、设置主机计算机名称# hostnamectl set-hostname controller4、本地主机名称和ip的解析# vim /etc/hosts192.168.0.104 controller5、安装ntp时间校准工具# yum -y install ntp# ntpdate asia.pool.ntp.org6、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.rpm7、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-python2、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 = utf83、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-server2、启动rabbit服务# systemctl enable rabbitmq-server.service# systemctl start rabbitmq-server.service3、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-keystoneclient3、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.Token4、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/ssl5、同步keystone到mariadb数据库# su -s /bin/sh -c "keystone-manage db_sync" keystone6、启动keystone服务并开机自启动# systemctl enable openstack-keystone.service# systemctl start openstack-keystone.service7、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 restart2、创建tenant、user and rolea.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
