Centos7.3 Openstack-liberty安裝部署記錄

一、環境

1.1 安全

本指南會告訴你如何使用 Red Hat Enterprise Linux 7和其衍生的EPEL倉庫安裝OpenStack。    
說明：目前統一采用Centos7.3版本進行Openstack-liberty版本的安裝。測試實驗了KVM環境下的創建安裝使用虛擬機。

1.2 主機網絡

1. 控制節點/計算節點 關閉防火墻和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

控制節點/計算節點配置hosts    
echo "192.168.0.231 controller" >> /etc/hosts    
echo "192.168.0.232 compute1" >> /etc/hosts

1.3 設置時間同步

1) 控制節點

# yum install -y chrony    
# vim /etc/chrony.conf    
allow 192.168/16 #允許那些服務器和自己同步時間

# systemctl enable chronyd.service           #開機啟動    
# systemctl start chronyd.service    
# timedatectl set-timezone Asia/Shanghai     #設置時區    
# timedatectl status

2）計算節點

# 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 安裝Openstack軟件包

1. 準備OpenStack安裝包 yum源

# vi CentOS-OpenStack-liberty.repo

[centos-openstack-liberty]

1.5 安裝SQL數據庫

1. 安裝數據庫

[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. 創建密碼: openstack

[root@controller ~]# mysql_secure_installation

3. 調整數據庫最大連接數：

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

[Service]新添加兩行如下參數：    
LimitNOFILE=10000    
LimitNPROC=10000

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

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

4. 創建數據庫

# 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 消息隊列 rabbitmq支持集群。

1）在控制節點上安裝與啟動rabbitmq, 監聽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 用戶:

# rabbitmqctl add_user openstack openstack

3) 授權用戶 openstack 讀、寫、配置的權限

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

4) 查看安裝插件

# rabbitmq-plugins list

5) 啟用管理插件

# 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

#會啟用如下服務：    
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）重啟

# systemctl start rabbitmq-server.service

會啟動15672端口的web界面

7) 登錄以及添加openstack為administrator

http://192.168.0.231:15672

guest/guest 默認密碼,也為管理員    

注：配置openstack/openstack為tags為administrator

二、 配置keystone

keystone 安裝在 controller 節點，為了提高服務性能，使用 apache 提供WEB請求，由 memcached 來保存 Token 信息

2.1 安裝keystone軟件包

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

2.2 配置 keystone

注意：不同版本號的keystone，其默認配置可能會有所不同

openssl rand -hex 10

c885b63d0ce5760ff23e

隨機一個值。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 初始化數據庫

1）初始化數據庫

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

##############################################################################    
會在/var/log/keystone/ 下生成一個keystone.log日志，keystone在啟動時會寫該文件。    
##############################################################################

2）驗證數據庫

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

3）啟動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服務器

1) 修改服務器名

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

2) 添加 keystone 的服務

# 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>

            Order allow,deny    
            Allow from all    
        </IfVersion>    
    </Directory>    
</VirtualHost>

3) 啟動HTTP服務器

systemctl enable httpd.service    
systemctl start httpd.service

驗證:

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

2.5 注冊服務實體及API

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

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

2.7 密碼驗證keystone正確性

為了驗證，臨時改環境變量, 要使用用戶名密碼驗證，不需要token驗證，要去掉環境變量。

[root@controller ~]# unset OS_TOKEN OS_URL

為 admin 用戶請求 token

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

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

2.8 使用環境變量腳本

1.創建 admin 用戶的環境腳本

[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.創建 demo 用戶的環境腳本

[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. 使用腳本測試    
[root@controller ~]# source admin-openrc.sh    
[root@controller ~]# openstack token issue    
+------------+----------------------------------+    
| Field      | Value                            |    
+------------+----------------------------------+

| user_id    | 4015e1151aee4ab7811f320378ce6031 |    
+------------+----------------------------------+

三、安裝鏡像服務(glance)

glance為用戶提供虛擬機鏡像的發現、注冊和取回服務。默認把鏡像存放在 /var/lib/glance/p_w_picpaths/ 目錄下

3.1 環境準備

使用 admin 權限

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

1) 創建 glance 用戶\把 service 項目、admin角色、glance 用戶關聯起來

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

2) 注冊名為p_w_picpath的服務

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

3) 注冊API端點

[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 安裝與配置

3.2.1 安裝程序包

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

3.2.2 修改glance配置

1. 配置鏡像的創建刪除回收服務

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. 配置云系統的鏡像注冊服務

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 導入數據

1）初始化數據庫

[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)

這個錯誤可以忽略, 可以用mysql測試數據庫登錄與創建是否成功。

2）驗證數據庫

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

3.3 啟動openstack-glance服務

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

驗證:

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

3.4  glance安裝驗證

我們使用一個非常小的系統鏡像來驗證 glance 是否成功部署

6.1 創建虛擬網絡

6.1.1 創建共享網絡

[root@controller ~]# source admin-openrc.sh    
[root@controller ~]# neutron net-create public --shared --provider:physical_network physnet1 --provider:network_type flat

Created a new network:    
+---------------------------+--------------------------------------+    
| Field                     | Value                                |    
+---------------------------+--------------------------------------+    
| admin_state_up            | True                                 |    
| id                        | 6759f3eb-a4c8-4503-b92b-da6daacf0ab4 |    
| mtu                       | 0                                    |    
| name                      | public                               |    
| port_security_enabled     | True                                 |    
| provider:network_type     | flat                                 |    
| provider:physical_network | physnet1                             |    
| provider:segmentation_id  |                                      |    
| router:external           | False                                |    
| shared                    | True                                 |    
| status                    | ACTIVE                               |    
| subnets                   |                                      |    
| tenant_id                 | 10952875490e43938d80d921337cb053     |    
+---------------------------+--------------------------------------+    
--shared 表示允許所有的項目使用該網絡

6.1.2 創建子網

[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                                     |    
| dns_nameservers   | 202.100.192.68                                     |    
| enable_dhcp       | True                                               |    
| gateway_ip        | 192.168.0.253                                      |    
| host_routes       |                                                    |    
| id                | da75b2db-56f4-45d2-b3f3-2ccf172f8798               |    
| ip_version        | 4                                                  |    
| ipv6_address_mode |                                                    |    
| ipv6_ra_mode      |                                                    |    
| name              | public-subunet                                     |    
| network_id        | 2e098da8-70f9-40bc-a393-868ed9a446cf               |    
| subnetpool_id     |                                                    |    
| tenant_id         | be420231d13848809da36178cbac4d22                   |    
+-------------------+----------------------------------------------------+

6.1.3 查看子網

[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 生成密鑰對

6.2.1 使用admin權限

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

6.2.2 生成密鑰對

如果已有密鑰，則可以不使用 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鑰

[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 添加安全規則組

默認情況下，安全規則組 default 會應用到所有的實例當中，它會通過防火墻規則來拒絕所有的遠程訪問。一般來說，我們通常會放行 ICMP 和 SSH 這兩種協議的訪問。

[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 通過虛擬控制臺訪問實例基于WEB的管理界面一般安裝在 controller 節點上。

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

7.2 配置dashboard參數

[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,    
}    
#時區設置    
TIME_ZONE = "Asia/Shanghai"

#創建虛擬機的時候可以修改密碼

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

7.3 配置開機啟動

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

7.4 驗證安裝是否成功

用瀏覽器打開：http://192.168.0.231/dashboard

域： default    
用戶： admin 或 demo 密碼為自己創建的密碼。

7.5  創建虛擬機實例

7.5.1 創建虛擬機實例過程

說明：官方下載的centos7鏡像。不知道密碼，需要在創建指定一個密碼，默認是centos7 可以SSH登錄，但是無法默認讓root直接ssh登錄，需要在創建虛擬機實例時取消root ssh登錄 。

如果你希望SSH可以使用密碼登錄。那么你需要用腳本修改ssh root登錄設置，不推薦用那個cirros鏡像測試。  
#!/bin/sh    
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config    
systemctl restart sshd

7.5.2 虛擬機控制臺登錄

測試SSH登錄

7.5.1 小節

通過安裝openstack的過程理解openstack各個組件的工作原理以及具體實現方式，在這個基礎上可以擴展其它內容。
