2-openstack基础环境准备
说明: linux-node1 控制节点
创新互联建站从2013年开始,先为洛南等服务建站,洛南等地企业,进行企业商务咨询服务。为洛南企业网站制作PC+手机+微官网三网同步一站式服务解决您的所有建站问题。
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/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.56.11 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sed sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config 防火墙: systemctl stop firewalld systemctl disable firewalld
2.3 配置时间同步(两台都做)
yum –y install chrony grep"allow" /etc/chrony.conf #打开 allow192.168/16 systemctl 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 -y systemctl enable rabbitmq-server.service systemctl 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
