说明： linux-node1 控制节点
linux-node2 计算节点
2.1.两台centos7服务器
主机名： [root@linux-node1 ~]# hostname linux-node1 [root@linux-node2 ~]# hostname linux-node2
IP： linux-node1 192.168.56.11/24 linux-node2 192.168.56.12/24
host解析cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.56.11 linux-node1 linux-node1.oldboyedu.com 192.168.56.12 linux-node2 linux-node2.oldboyedu.com
2.2 selinux 和防火墙关闭
[root@linux-node2 ~]# getenforce Disabled[root@linux-node1 ~]# getenforce Disabled#可以用sedsed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config防火墙：systemctl stop firewalldsystemctl disable firewalld
2.3 配置时间同步(两台都做)
yum –y install chronygrep"allow" /etc/chrony.conf #打开allow192.168/16systemctl enable chronyd.service #设置开机自启systemctl start chronyd.service #启动timedatectl set-timezone Asia/Shanghai #同步时区
2.4 在linux-node1 上安装数据库
yum install -y mariadb mariadb-serverMySQl-python #安装数据库\cp /usr/share/mysql/my-medium.cnf /etc/my.cnf #拷贝配置文件在vi /etc/my.cnf 添加如下几行[mysqld]default-storage-engine = innodb #默认的存储引擎innodb_file_per_table #使用独享的表空间collation-server = utf8_general_ci #设置校对规则init-connect = 'SET NAMES utf8' #设置链接的字符集character-set-server = utf8 #设置默认的字符集systemctl enable mariadb.service #开机启动数据库systemctl start mariadb.service #立马启动数据库
2.5 初始化数据库
2.6 为各个组件创建数据库并收授权
2.6.1 keystone
MariaDB[(none)]> create database keystone;Query OK,1 row affected (0.01 sec)MariaDB[(none)]> grant all on keystone.* to 'keystone'@'localhost' identified by'keystonne';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> grant all on keystone.* to 'keystone'@'%' identified by'keystone';Query OK, 0 rows affected (0.00 sec)
2.6.2 glance
MariaDB[(none)]> create database glance;Query OK,1 row affected (0.00 sec)MariaDB[(none)]> grant all on glance.* to 'glance'@'%' identified by 'glance';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> grant all on glance.* to 'glance'@'localhost' identified by'glance';
2.6.3 nova和nova_api
MariaDB[(none)]> create database nova;Query OK,1 row affected (0.00 sec)MariaDB[(none)]> grant all on nova.* to 'nova'@'%' identified by 'nova';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> grant all on nova.* to 'nova'@'localhost' identified by 'nova';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> create database nova_api;Query OK,1 row affected (0.00 sec)MariaDB[(none)]> grant all on nova_api.* to 'nova'@'localhost' identified by'nova';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> grant all on nova_api.* to 'nova'@'%' identified by 'nova';
2.6.4 neutron
MariaDB[(none)]> create database neutron;Query OK,1 row affected (0.00 sec)MariaDB[(none)]> grant all on neutron.* to 'neutron'@'%' identified by 'neutron';Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> grant all on neutron.* to 'neutron'@'localhost' identified by'neutron';;Query OK,0 rows affected (0.00 sec)MariaDB[(none)]> flush privileges;Query OK, 0 rows affected (0.00 sec)
2.6.5 检验数据库
MariaDB[(none)]> show databases;+--------------------+|Database |+--------------------+|information_schema ||glance ||keystone ||mysql ||neutron ||nova || nova_api ||performance_schema |+--------------------+8 rows inset (0.00 sec) MariaDB[(none)]>
2.7 安装消息队列（rabbitmq）
2.7.1 基本安装
yuminstall rabbitmq-server -ysystemctl enable rabbitmq-server.servicesystemctl start rabbitmq-server.service[root@linux-node1~]# rabbitmqctl add_user openstack openstack #创建消息队列认证用户Creatinguser "openstack" ......done.[root@linux-node1~]##创建的用户得授权才能使用[root@linux-node1~]# rabbitmqctl set_permissions openstack ".*" ".*"".*" #授权用户才能使用Settingpermissions for user "openstack" in vhost "/" ......done.
2.7.2 web界面安装
查看组件[root@linux-node1~]# rabbitmq-plugins list[ ]amqp_client 3.3.5[ ]cowboy 0.5.0-rmq3.3.5-git4b93c2d[ ]eldap 3.3.5-gite309de4[ ]mochiweb 2.7.0-rmq3.3.5-git680dba8[ ]rabbitmq_amqp1_0 3.3.5[ ]rabbitmq_auth_backend_ldap 3.3.5[ ]rabbitmq_auth_mechanism_ssl 3.3.5[ ]rabbitmq_consistent_hash_exchange 3.3.5[ ]rabbitmq_federation 3.3.5[ ]rabbitmq_federation_management 3.3.5[ ]rabbitmq_management 3.3.5[ ]rabbitmq_management_agent 3.3.5[ ]rabbitmq_management_visualiser 3.3.5[ ]rabbitmq_mqtt 3.3.5[ ]rabbitmq_shovel 3.3.5[ ]rabbitmq_shovel_management 3.3.5[ ]rabbitmq_stomp 3.3.5[ ]rabbitmq_test 3.3.5[ ]rabbitmq_tracing 3.3.5[ ]rabbitmq_web_dispatch 3.3.5[ ]rabbitmq_web_stomp 3.3.5[ ]rabbitmq_web_stomp_examples 3.3.5[ ]sockjs 0.3.4-rmq3.3.5-git3132eb9[ ]webmachine 1.10.3-rmq3.3.5-gite9359c7加载组件 rabbitmq-plugins enable rabbitmq_management systemctlrestart rabbitmq-server.service #重启消息队列说明 rabbitmq监听的是5672 rabbitmq的管理界面监听的是15672
2.7.3 访问测试
默认是用户guest 密码是guest
让openstack用户拥有admistrator的权限进行登录
