OpenStack-部署

云是一种模式，通过网络来使用，可以根据需求付费。

云有3种模式，公有云 私有云 混合云。

云安装部署前期安装软件 

生产环境要注意：时间一定要同步，另外主机名要提前定好，防火墙要关闭

在两个节点都安装：

yum install https://repos.fedorapeople.org/repos/openstack/openstack-newton/rdo-release-newton-5.noarch.rpm   下载和安装RDO仓库RPM来启用OpenStack仓库。

1.安装仓库：

yum install centos-release-openstack-newton -y

2.安装 OpenStack 客户端：

# yum install python-openstackclient -y

# yum install openstack-selinux -y

在linux-node1上安装：

3.安装数据库： # yum install mariadb mariadb-server python2-PyMySQL -y

vim /etc/my.cnf.d/openstack.cnf

[mysqld]
bind-address = 192.168.1.102
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

启动数据库服务，并将其配置为开机自启
# systemctl enable mariadb.service
# systemctl start mariadb.service

为了保证数据库服务的安全性，运行``mysql_secure_installation``脚本。特别需要说明的是，为数据库的root用户设置一个适当的密码。

# mysql_secure_installation

4.安装消息队列： # yum install rabbitmq-server.

启动消息队列服务并将其配置为随系统启动：

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

添加 openstack 用户：

rabbitmqctl add_user openstack openstack

给``openstack``用户配置写和读权限：

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

开启rabbitmq的web界面

rabbitmq-plugins enable rabbitmq_management

lsof -i:15672检查是否开启

192.168.1.102:15672

登录默认账号密码guest guest

5.其它服务提前安装： # yum install openstack-keystone httpd mod_wsgi

# yum install openstack-glance

# yum install openstack-nova-api openstack-nova-conductor   openstack-nova-console openstack-nova-novncproxy   openstack-nova-scheduler

# yum install openstack-neutron openstack-neutron-ml2   openstack-neutron-linuxbridge ebtables

 6.创建数据库并授权

create database glance;
create database glance;
create database nova;
create database nove_api;
create database neutron;
create database cinder;
grant all on keystone.* to 'keystone'@'localhost' identified by 'keystone';
grant all on keystone.* to 'keystone'@'%' identified by 'keystoone'; 
grant all on glance.* to 'glance'@'localhost' identified by 'glance';
grant all on glance.* to 'glance'@'%' identified by 'glance';
grant all on nova.* to 'nova'@'localhost' identified by 'nova';
grant all on nova.* to 'nova'@'%' identified by 'nova';
grant all on nova_api.* to 'nova'@'localhost' identified by 'nova'ova';
grant all on nova_api.* to 'nova'@'%' identified by 'nova';
grant all on neutron.* to 'neutron'@'localhost' identified by 'neutron';
grant all on neutron.* to 'neutron'@'%' identified by 'neutron'';
grant all on cinder.* to 'cinder'@'localhost' identified by 'cinder';
grant all on cinder.* to 'cinder'@'%' identified by 'cinder';

 7.安装认证并配置

yum install openstack-keystone httpd mpd_wsgi
vim /etc/keystone/keystone.conf
在640行改成数据库机子
connection = mysql+pymysql://keystone:keystone@192.168.1.102/keystone
