基于OpenStack构建企业私有云（1）环境搭建

一.基础软件包安装

1.安装EPEL仓库

# rpm -ivh http://mirrors.aliyun.com/epel ... h.rpm

2.安装OpenStack仓库

# yum install -y centos-release-openstack-queens

3.安装OpenStack客户端

# yum install -y python-openstackclient
4.安装openstack SELinux管理包

# yum install -y openstack-selinux

二.MySQL数据库部署

1.MySQL安装

[root@linux-node1 ~]# yum install -y mariadb mariadb-server python2-PyMySQL

2.修改MySQL配置文件

[root@linux-node1 ~]# vim /etc/my.cnf.d/openstack.cnf

[mysqld]

bind-address = 192.168.56.11 #设置监听的IP地址

default-storage-engine = innodb  #设置默认的存储引擎

innodb_file_per_table = on#使用独享表空间

collation-server = utf8_general_ci #服务器的默认校对规则

character-set-server = utf8 #服务器安装时指定的默认字符集设定

max_connections = 4096 #设置MySQL的最大连接数，生产请根据实际情况设置。 

3.启动MySQL Server并设置开机启动

[root@linux-node1 ~]# systemctl enable mariadb.service

[root@linux-node1 ~]# systemctl start mariadb.service

4.进行数据库安全设置

[root@linux-node1 ~]# mysql_secure_installation

5.数据库创建

[root@linux-node1 ~]# mysql -u root -p

Enter password:

…

MariaDB [(none)]>

Keystone数据库

CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';

Glance数据库

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance';

Nova数据库

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova';

CREATE DATABASE nova_api;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova';

CREATE DATABASE nova_cell0;

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova';

Neutron 数据库

CREATE DATABASE neutron;

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'neutron';

GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'neutron';

Cinder数据库

CREATE DATABASE cinder;

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';

三：消息代理RabbitMQ

1.安装RabbitMQ

[root@linux-node1 ~]# yum install -y rabbitmq-server

2.设置开启启动，并启动RabbitMQ

[root@linux-node1 ~]# systemctl enable rabbitmq-server.service

[root@linux-node1 ~]# systemctl start rabbitmq-server.service

3.添加openstack用户。

[root@linux-node1 ~]# rabbitmqctl add_user openstack openstack

Creating user "openstack" ...

4.给刚才创建的openstack用户，创建权限。

[root@linux-node1 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

Setting permissions for user "openstack" in vhost "/" ...

5.启用Web监控插件

[root@linux-node1 ~]# rabbitmq-plugins list

[root@linux-node1 ~]# rabbitmq-plugins enable rabbitmq_management
