一、环境

1.1 安全

本指南会告诉你如何使用 Red Hat Enterprise Linux 7和其衍生的EPEL仓库安装OpenStack。    
说明：目前统一采用Centos7.3版本进行Openstack-liberty版本的安装。测试实验了KVM环境下的创建安装使用虚拟机。

1.2 主机网络

1. 控制节点/计算节点 关闭防火墙和SELinux

systemctl stop iptables    
systemctl stop firewalld  
systemctl disable firewalld    
setenforce 0    
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux

yum install vim net-tools

 

2. 配置hosts文件

控制节点/计算节点配置hosts    
echo "192.168.0.231 controller" >> /etc/hosts    
echo "192.168.0.232 compute1" >> /etc/hosts

 

1.3 设置时间同步

1) 控制节点

# yum install -y chrony    
# vim /etc/chrony.conf    
allow 192.168/16 #允许那些服务器和自己同步时间

# systemctl enable chronyd.service           #开机启动    
# systemctl start chronyd.service    
# timedatectl set-timezone Asia/Shanghai     #设置时区    
# timedatectl status

 

2）计算节点

# yum install -y chrony    
# vim /etc/chrony.conf    
server 192.168.1.17 iburst #只留一行

# systemctl enable chronyd.service    
# systemctl start chronyd.service    
# timedatectl set-timezone Asia/Shanghai    
# chronyc sources

 

1.4 安装Openstack软件包

1. 准备OpenStack安装包 yum源

# vi CentOS-OpenStack-liberty.repo

[centos-openstack-liberty]    
name=CentOS-7 - OpenStack liberty    
baseurl=http://mirrors.aliyun.com/centos/7/cloud/$basearch/openstack-liberty/    
gpgcheck=0    
enabled=1    
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Centos-7

[centos-openstack-liberty-test]    
name=CentOS-7 - OpenStack liberty Testing    
baseurl=http://buildlogs.centos.org/centos/7/cloud/$basearch/openstack-liberty/    
gpgcheck=0    
enabled=0


# 或采用 CentOS7安装OpenStack提供的epel源

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

 

2. 安装openstack
1) 控制节点安装 openstack

#Base    
yum install -y http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm    
yum install -y centos-release-openstack-liberty

##Neutron    
yum install -y openstack-neutron openstack-neutron-linuxbridge ebtables ipset

##Cinder    
yum install -y openstack-cinder python-cinderclient targetcli python-oslo-policy

 

1.5 安装SQL数据库

1. 安装数据库

[root@controller ~]# yum install mariadb mariadb-server MySQL-python    
[root@controller ~]# vi /etc/my.cnf.d/mariadb_openstack.cnf

[mysqld]    
bind-address = 192.168.0.231    
default-storage-engine = innodb    
innodb_file_per_table    
collation-server = utf8_general_ci    
init-connect = 'SET NAMES utf8'    
character-set-server = utf8    
max_connections=1000

[root@controller ~]# systemctl enable mariadb.service    
[root@controller ~]# systemctl start mariadb.service

2. 创建密码: openstack

[root@controller ~]# mysql_secure_installation

3. 调整数据库最大连接数：

[root@controller ~]# vi /usr/lib/systemd/system/mariadb.service

[Service]新添加两行如下参数：    
LimitNOFILE=10000    
LimitNPROC=10000

systemctl --system daemon-reload    
systemctl restart mariadb.service

mysql -uroot -popenstack    
SQL> show variables like 'max_connections';

 

4. 创建数据库

# mysql -u root -p

CREATE DATABASE keystone;    
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'openstack';    
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'openstack';

CREATE DATABASE glance;    
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'openstack';    
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'openstack';

CREATE DATABASE nova;    
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'openstack';    
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'openstack';

CREATE DATABASE neutron;    
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'openstack';    
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'openstack';

CREATE DATABASE cinder;    
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';    
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'openstack';

FLUSH PRIVILEGES;    
SHOW DATABASES;

 

1.6 消息队列 rabbitmq支持集群。

1）在控制节点上安装与启动rabbitmq, 监听5672端口

yum install rabbitmq-server

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

# netstat -tunlp  | grep 5672    
tcp        0      0 0.0.0.0:15672           0.0.0.0:*               LISTEN      1694/beam.smp      
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      1694/beam.smp      
tcp6       0      0 :::5672                 :::*                    LISTEN      1694/beam.smp

 

2) 添加 openstack 用户:

# rabbitmqctl add_user openstack openstack

3) 授权用户 openstack 读、写、配置的权限

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

4) 查看安装插件

# rabbitmq-plugins list

5) 启用管理插件

# rabbitmq-plugins enable rabbitmq_management

The following plugins have been enabled:    
  mochiweb    
  webmachine    
  rabbitmq_web_dispatch    
  amqp_client    
  rabbitmq_management_agent    
  rabbitmq_management    
Applying plugin configuration to rabbit@controller... started 6 plugins.

# rabbitmq-plugins list

#会启用如下服务：    
Configured: E = explicitly enabled; e = implicitly enabled    
| Status:   * = running on rabbit@controller    
|/    
[e*] amqp_client                       3.6.5    
[e*] mochiweb                          2.13.1    
[E*] rabbitmq_management               3.6.5    
[e*] rabbitmq_management_agent         3.6.5    
[e*] rabbitmq_web_dispatch             3.6.5    
[e*] webmachine                        1.10.3

 

6）重启

# systemctl start rabbitmq-server.service

会启动15672端口的web界面

 

7) 登录以及添加openstack为administrator

http://192.168.0.231:15672

guest/guest 默认密码,也为管理员    
Centos7.3 Openstack-liberty安装部署记录

注：配置openstack/openstack为tags为administrator

 

二、 配置keystone

keystone 安装在 controller 节点，为了提高服务性能，使用 apache 提供WEB请求，由 memcached 来保存 Token 信息

2.1 安装keystone软件包

# yum install openstack-keystone httpd mod_wsgi memcached python-memcached

 

2.2 配置 keystone

注意：不同版本号的keystone，其默认配置可能会有所不同

openssl rand -hex 10

c885b63d0ce5760ff23e

随机一个值。改成admin_token值

cat /etc/keystone/keystone.conf |grep -v "^#" | grep -v "^$"

[DEFAULT]    
admin_token = c885b63d0ce5760ff23e

[database]    
connection = mysql://keystone:openstack@192.168.0.231/keystone

[memcache]    
servers = 192.168.0.231:11211

[revoke]    
driver = sql

[token]    
provider = uuid    
driver = memcache

 

2.3 初始化数据库

1）初始化数据库

# chown -R keystone:keystone /var/log/keystone    
# su -s /bin/sh -c "keystone-manage db_sync" keystone

##############################################################################    
会在/var/log/keystone/ 下生成一个keystone.log日志，keystone在启动时会写该文件。    
##############################################################################

2）验证数据库

# mysql -h 192.168.0.231 -ukeystone -popenstack -e "use keystone;show tables;"

3）启动memcache

systemctl enable memcached.service    
systemctl start memcached.service

# netstat -tunlp | grep 11211    
tcp        0      0 127.0.0.1:11211         0.0.0.0:*               LISTEN      3288/memcached     
tcp6       0      0 ::1:11211               :::*                    LISTEN      3288/memcached     
udp        0      0 127.0.0.1:11211         0.0.0.0:*                           3288/memcached     
udp6       0      0 ::1:11211               :::*                                3288/memcached

 

2.4 配置HTTP服务器

1) 修改服务器名

# vi /etc/httpd/conf/httpd.conf    
ServerName 192.168.0.231:80

 

2) 添加 keystone 的服务

# vi /etc/httpd/conf.d/wsgi-keystone.conf

Listen 5000    
Listen 35357

<VirtualHost *:5000>    
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}    
    WSGIProcessGroup keystone-public    
    WSGIScriptAlias / /usr/bin/keystone-wsgi-public    
    WSGIApplicationGroup %{GLOBAL}    
    WSGIPassAuthorization On    
    <IfVersion >= 2.4>    
      ErrorLogFormat "%{cu}t %M"    
    </IfVersion>    
    ErrorLog /var/log/httpd/keystone-error.log    
    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>    
        <IfVersion >= 2.4>    
            Require all granted    
        </IfVersion>    
        <IfVersion < 2.4>    
            Order allow,deny    
            Allow from all    
        </IfVersion>    
    </Directory>    
</VirtualHost>

<VirtualHost *:35357>    
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}    
    WSGIProcessGroup keystone-admin    
    WSGIScriptAlias / /usr/bin/keystone-wsgi-admin    
    WSGIApplicationGroup %{GLOBAL}    
    WSGIPassAuthorization On    
    <IfVersion >= 2.4>    
      ErrorLogFormat "%{cu}t %M"    
    </IfVersion>    
    ErrorLog /var/log/httpd/keystone-error.log    
    CustomLog /var/log/httpd/keystone-access.log combined

    <Directory /usr/bin>    
        <IfVersion >= 2.4>    
            Require all granted    
        </IfVersion>    
        <IfVersion < 2.4>    
            Order allow,deny    
            Allow from all    
        </IfVersion>    
    </Directory>    
</VirtualHost>

 

3) 启动HTTP服务器

systemctl enable httpd.service    
systemctl start httpd.service

验证:

[root@controller ~]# ss -ntl | grep -E "5000|35357"    
LISTEN     0      128          *:35357                    *:*                 
LISTEN     0      128          *:5000                     *:*                 

 

2.5 注册服务实体及API

2.5.1 配置环境变量

[root@controller ~]#

export OS_TOKEN=c885b63d0ce5760ff23e    
export OS_URL=http://192.168.0.231:35357/v3    
export OS_IDENTITY_API_VERSION=3

 

2.5.2 keystone服务注册

[root@controller ~]# openstack service create --name keystone --description "OpenStack Identity" identity

2.5.3 keystone API注册admin 管理的、public公共的、internal内部的

+----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------------+

2.6 创建项目、用户及规则

2.6.1 创建 admin 项目\admin 用户\ admin 角色并把 admin 项目、admin 角色、admin 用户关联起来

[root@controller ~]# openstack project create --domain default --description "Admin Project" admin    
[root@controller ~]# openstack user create --domain default --password=openstack admin    
[root@controller ~]# openstack role create admin    
[root@controller ~]# openstack role add --project admin --user admin admin

[root@controller ~]# openstack user list    
+----------------------------------+-------+    
| ID                               | Name  |    
+----------------------------------+-------+    
| e2bae88d31b54e4ab1a4cb2251da8a6a | admin |

+----------------------------------+---------+

[root@linux-node1 ~]# openstack endpoint delete ID    

 

2.7 密码验证keystone正确性

为了验证，临时改环境变量, 要使用用户名密码验证，不需要token验证，要去掉环境变量。

[root@controller ~]# unset OS_TOKEN OS_URL

为 admin 用户请求 token

[root@controller ~]# openstack --os-auth-url http://192.168.0.231:35357/v3 \    
   --os-project-domain-id default --os-user-domain-id default \

| user_id    | afd908684eee42aaa7d73e22671eee24 |    
+------------+----------------------------------+

 

2.8 使用环境变量脚本

1.创建 admin 用户的环境脚本

[root@controller ~]# vim admin-openrc.sh    
export OS_PROJECT_DOMAIN_ID=default    
export OS_USER_DOMAIN_ID=default    
export OS_PROJECT_NAME=admin    
export OS_TENANT_NAME=admin    
export OS_USERNAME=admin    
export OS_PASSWORD=openstack    
export OS_AUTH_URL=http://192.168.0.231:35357/v3    
export OS_IDENTITY_API_VERSION=3

 

2.创建 demo 用户的环境脚本

[root@controller ~]# vim demo-openrc.sh    
export OS_PROJECT_DOMAIN_ID=default    
export OS_USER_DOMAIN_ID=default    
export OS_PROJECT_NAME=demo    
export OS_TENANT_NAME=demo    
export OS_USERNAME=demo    
export OS_PASSWORD=openstack    
export OS_AUTH_URL=http://192.168.0.231:5000/v3    
export OS_IDENTITY_API_VERSION=3

 

3. 使用脚本测试    
[root@controller ~]# source admin-openrc.sh    
[root@controller ~]# openstack token issue    
+------------+----------------------------------+    
| Field      | Value                            |    
+------------+----------------------------------+    
| expires    | 2017-05-10T03:19:08.928697Z      |    
| id         | df25646c15cb433ab7251dcd0308ecbf |    
| project_id | 79d295e81e5a4255a02a8ea26ae4606a |    
| user_id    | 4015e1151aee4ab7811f320378ce6031 |    
+------------+----------------------------------+

 

三、安装镜像服务(glance)

glance为用户提供虚拟机镜像的发现、注册和取回服务。默认把镜像存放在 /var/lib/glance/p_w_picpaths/ 目录下

3.1 环境准备

使用 admin 权限

[root@controller ~]# source admin-openrc.sh

1) 创建 glance 用户\把 service 项目、admin角色、glance 用户关联起来

[root@controller ~]# openstack user create --domain default --password=openstack glance    
[root@controller ~]# openstack role add --project service --user glance admin

2) 注册名为p_w_picpath的服务

[root@controller ~]# openstack service create --name glance --description "OpenStack Image service" p_w_picpath

3) 注册API端点

[root@controller ~]# openstack endpoint create --region RegionOne  p_w_picpath public http://192.168.0.231:9292    
[root@controller ~]# openstack endpoint create --region RegionOne  p_w_picpath internal http://192.168.0.231:9292    
[root@controller ~]# openstack endpoint create --region RegionOne  p_w_picpath admin http://192.168.0.231:9292

 

3.2 安装与配置

3.2.1 安装程序包

[root@controller ~]# yum install openstack-glance python-glance python-glanceclient

 

3.2.2 修改glance配置

1. 配置镜像的创建删除回收服务

cat /etc/glance/glance-api.conf |grep -v "^#" | grep -v "^$"

[DEFAULT]    
verbose=True    
notification_driver = noop

[database]    
connection = mysql://glance:openstack@192.168.0.231/glance

[glance_store]    
default_store=file    
filesystem_store_datadir=/var/lib/glance/p_w_picpaths/

[keystone_authtoken]    
auth_uri=http://192.168.0.231:5000    
auth_url=http://192.168.0.231:35357    
auth_plugin=password    
project_domain_id=default    
user_domain_id=default    
project_name=service    
username=glance    
password=openstack

[paste_deploy]    
flavor=keystone

 

2. 配置云系统的镜像注册服务

cat /etc/glance/glance-registry.conf |grep -v "^#" | grep -v "^$"

[DEFAULT]    
verbose=True    
notification_driver = noop

[database]    
connection = mysql://glance:openstack@192.168.0.231/glance

[keystone_authtoken]    
auth_uri=http://192.168.0.231:5000    
auth_url=http://192.168.0.231:35357    
auth_plugin=password    
project_domain_id=default    
user_domain_id=default    
project_name=service    
username=glance    
password=openstack

[paste_deploy]    
flavor=keystone

 

3.2.3 导入数据

1）初始化数据库

[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance

No handlers could be found for logger "oslo_config.cfg"    
/usr/lib64/python2.7/site-packages/sqlalchemy/engine/default.py:450: Warning: Duplicate index `ix_p_w_picpath_properties_p_w_picpath_id_name`. This is deprecated and will be disallowed in a future release.    
  cursor.execute(statement, parameters)

这个错误可以忽略, 可以用mysql测试数据库登录与创建是否成功。

 

2）验证数据库

# mysql -h 192.168.0.231 -uglance -popenstack -e "use glance;show tables;"

 

3.3 启动openstack-glance服务

# systemctl enable openstack-glance-api.service openstack-glance-registry.service    
# systemctl start openstack-glance-api.service openstack-glance-registry.service

验证:

[root@controller ~]# ss -ntl | grep -E "9191|9292"    
LISTEN     0      128          *:9292                     *:*                 
LISTEN     0      128          *:9191                     *:*          

 

3.4  glance安装验证

我们使用一个非常小的系统镜像来验证 glance 是否成功部署

1. 修改环境变量脚本

+---------------------------+--------------------------------------+    
--shared 表示允许所有的项目使用该网络

 

6.1.2 创建子网

[root@controller ~]# neutron subnet-create public 192.168.0.0/24 --name public-subunet --allocation-pool start=192.168.0.200,end=192.168.0.210\    
   --dns-nameserver 202.100.192.68 --gateway 192.168.0.253

Created a new subnet:    
+-------------------+----------------------------------------------------+    
| Field             | Value                                              |    
+-------------------+----------------------------------------------------+    
| allocation_pools  | {"start": "192.168.0.200", "end": "192.168.0.210"} |    
| cidr              | 192.168.0.0/24                                     |

| tenant_id         | be420231d13848809da36178cbac4d22                   |    
+-------------------+----------------------------------------------------+

 

6.1.3 查看子网

[root@controller ~]# neutron net-list 

+--------------------------------------+--------+-----------------------------------------------------+    
| id                                   | name   | subnets                                             |    
+--------------------------------------+--------+-----------------------------------------------------+    
| 2e098da8-70f9-40bc-a393-868ed9a446cf | public | da75b2db-56f4-45d2-b3f3-2ccf172f8798 192.168.0.0/24 |    
+--------------------------------------+--------+-----------------------------------------------------+

[root@controller ~]#  neutron subnet-list    
+--------------------------------------+----------------+----------------+----------------------------------------------------+    
| id                                   | name           | cidr           | allocation_pools                                   |    
+--------------------------------------+----------------+----------------+----------------------------------------------------+    
| da75b2db-56f4-45d2-b3f3-2ccf172f8798 | public-subunet | 192.168.0.0/24 | {"start": "192.168.0.200", "end": "192.168.0.210"} |    
+--------------------------------------+----------------+----------------+----------------------------------------------------+

 

6.2 生成密钥对

6.2.1 使用admin权限

[root@controller ~]#  source admin-openrc.sh

6.2.2 生成密钥对

如果已有密钥，则可以不使用 ssh-keygen 重新生成

[root@controller ~]# ssh-keygen -q -N ""    
Enter file in which to save the key (/root/.ssh/id_rsa):    
[root@controller ~]# nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey

6.2.3 查看有哪些可用的密钥

[root@controller ~]# nova keypair-list    
+-------+-------------------------------------------------+    
| Name  | Fingerprint                                     |    
+-------+-------------------------------------------------+    
| mykey | bc:ca:8e:bb:61:01:7f:8a:ab:5e:d8:b2:2c:35:b7:83 |    
+-------+-------------------------------------------------+

6.3 添加安全规则组

默认情况下，安全规则组 default 会应用到所有的实例当中，它会通过防火墙规则来拒绝所有的远程访问。一般来说，我们通常会放行 ICMP 和 SSH 这两种协议的访问。

[root@controller ~]# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0    
[root@controller ~]# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

 

七、控制面板（horizon）

7.1 通过虚拟控制台访问实例基于WEB的管理界面一般安装在 controller 节点上。

[root@controller ~]# yum install openstack-dashboard

7.2 配置dashboard参数

[root@controller ~]# vi /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller"    
ALLOWED_HOSTS = ['*', ]    
CACHES = {    
    'default': {    
         'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',    
         'LOCATION': '127.0.0.1:11211',    
    }    
}    
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"    
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True    
OPENSTACK_API_VERSIONS = {    
    "identity": 3,    
    "volume": 2,    
}    
OPENSTACK_NEUTRON_NETWORK = {    
    ...    
    'enable_router': False,    
    'enable_quotas': False,    
    'enable_distributed_router': False,    
    'enable_ha_router': False,    
    'enable_lb': False,    
    'enable_firewall': False,    
    'enable_***': False,    
    'enable_fip_topology_check': False,    
}    
#时区设置    
TIME_ZONE = "Asia/Shanghai"

#创建虚拟机的时候可以修改密码

OPENSTACK_HYPERVISOR_FEATURES = {    
    'can_set_mount_point': True,    
    'can_set_password': True,    
    'requires_keypair': True,    
}

 

7.3 配置开机启动

[root@controller ~]# systemctl enable httpd.service memcached.service    
[root@controller ~]# systemctl restart httpd.service memcached.service

 

7.4 验证安装是否成功

用浏览器打开：http://192.168.0.231/dashboard

域： default    
用户： admin 或 demo 密码为自己创建的密码。

7.5  创建虚拟机实例

7.5.1 创建虚拟机实例过程

说明：官方下载的centos7镜像。不知道密码，需要在创建指定一个密码，默认是centos7 可以SSH登录，但是无法默认让root直接ssh登录，需要在创建虚拟机实例时取消root ssh登录 。

如果你希望SSH可以使用密码登录。那么你需要用脚本修改ssh root登录设置，不推荐用那个cirros镜像测试。  
#!/bin/sh    
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config    
systemctl restart sshd
