2-openstack基础环境准备

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
