1、前言

本文旨在记录本人的一个实验过程，因为其中有一些坑，方便以后回顾查询。

其中限于篇幅（大部分是配置部分）有些内容省略掉了，官网都有，各位如果是安装部署的话可以参考官网，不建议使用本文。

以下是ocata版本官网链接

https://docs.openstack.org/ocata/zh_CN/install-guide-rdo/common/conventions.html

2、环境

在centOS 7中部署Openstack，按照官网只需要控制节点和计算节点，网络节点安装和控制节点安装在一起

版本：openstack-ocata

2.1、约定

/etc/hosts

# controller

192.168.2.19 controller

# compute1

192.168.2.21 compute1

# block1

192.168.2.21 block1

# object1

192.168.2.21 object1

# object2

192.168.2.21 object2

控制节点和计算节点都需要两个网络接口，一个作为管理网络接口，一个作为外部网络接口。接口配置如下：

节点名称	网络名称	IP地址	子网掩码	默认网关
控制节点	管理网络	192.168.2.19	255.255.255.0	192.168.2.1
	外部网络	10.1.12.10	255.255.255.0	10.1.12.1
计算节点	管理网络	192.168.2.21	255.255.255.0	192.168.2.1
	外部网络	10.1.12.11	255.255.255.0	10.1.12.1

2.2、关闭

永久关闭：vi /etc/selinux/config

SELINUX=disabled

临时关闭：setenforce 0

关闭iptables

永久关闭：systemctl disable firewalld.service

systemctl disable firewalld

临时关闭：systemctl stop firewalld.service

systemctl stop firewalld

sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

2.3、时区设置

timedatectl set-timezone Asia/Shanghai

2.4、密码表

密码名称	描述
数据库密码(不能使用变量)	数据库的root密码（空）
ADMIN_PASS	admin 用户密码（111111）
CINDER_DBPASS	块设备存储服务的数据库密码
CINDER_PASS	块设备存储服务的 cinder 密码
DASH_DBPASS	Database password for the Dashboard
DEMO_PASS	demo 用户的密码
GLANCE_DBPASS	镜像服务的数据库密码（glance）
GLANCE_PASS	镜像服务的 glance 用户密码（111111）
KEYSTONE_DBPASS	认证服务的数据库密码（keystone）
METADATA_SECRET	Secret for the metadata proxy（111111）
NEUTRON_DBPASS	网络服务的数据库密码（neutron）
NEUTRON_PASS	网络服务的 neutron 用户密码（111111）
NOVA_DBPASS	计算服务的数据库密码（nova）
NOVA_PASS	计算服务中``nova``用户的密码（111111）
PLACEMENT_PASS	Password of the Placement service user placement（111111）
RABBIT_PASS	RabbitMQ的openstack用户密码（rabbit）

2.5、yum本地源

rpm.tar.gz（/var/cache/yum/$basearch/$releasever“/var/cache/yum/x86_64/7”打包）再解压就相当于用来本地yum源，别忘了打开/etc/yum.conf中缓存。

2.6、OpenStack包

启用OpenStack库

yum install centos-release-openstack-ocata -y

yum upgrade -y

yum install python-openstackclient -y

2.7、SQL数据库

2.7.1、安全并配置组件

yum install mariadb mariadb-server python2-PyMySQL -y

cat >/etc/my.cnf.d/openstack.cnf<<eof
[mysqld]
bind-address = 192.168.2.19
#
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
eof

systemctl enable mariadb.service
systemctl start mariadb.service
mysql_secure_installation

2.8、消息队列

消息队列运行在控制节点。

2.8.1、安全并配置组件

yum install rabbitmq-server -y
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

rabbitmqctl add_user openstack rabbit
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

2.9、Memcached

各类服务的身份认证机制使用Memcached缓存令牌。

缓存服务memecached通常运行在控制节点。

在生产部署中，我们推荐联合启用防火墙、认证和加密保证它的安全。

2.9.1、安全并配置组件

yum install memcached python-memcached -y
sed -i 's#OPTIONS="-l 127.0.0.1,::1"#OPTIONS="-l 127.0.0.1,::1,controller"#g' /etc/sysconfig/memcached
systemctl enable memcached.service
systemctl start memcached.service

3、认证服务

3.1、安装和配置

3.1.1、先决条件

mysql -u root -proot
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'keystone';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'keystone';
exit

生成一个随机值在初始的配置中作为管理员的令牌。

openssl rand -hex 10

66ef83a4b21cebde6996

3.1.2、安全并配置组件

yum install openstack-keystone httpd mod_wsgi -y

vim /etc/keystone/keystone.conf

su -s  /bin/sh -c "keystone-manage db_sync" keystone
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
keystone-manage bootstrap --bootstrap-password 111111 \
  --bootstrap-admin-url http://controller:35357/v3/ \
  --bootstrap-internal-url http://controller:5000/v3/ \
  --bootstrap-public-url http://controller:5000/v3/ \
  --bootstrap-region-id RegionOne

3.1.3、配置 Apache HTTP 服务器

echo ServerName controller >> /etc/httpd/conf/httpd.conf
ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

3.1.4、完成安装

systemctl enable httpd.service
systemctl restart httpd.service

 export OS_PROJECT_NAME=admin
 export OS_USER_DOMAIN_NAME=Default
 export OS_PROJECT_DOMAIN_NAME=Default
 export OS_AUTH_URL=http://controller:35357/v3
 export OS_IDENTITY_API_VERSION=3

..........................................................................................................
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3

慎用：不然会报错（经测试没问题黄线上面的就可以）
export OS_TOKEN=66ef83a4b21cebde6996
export OS_USERNAME=admin
export OS_PASSWORD=111111
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default

3.2、创建域、项目、用户和角色

openstack project create --domain default \
  --description "Service Project" service 
openstack project create --domain default \
  --description "Demo Project" demo
openstack user create --domain default \
  --password-prompt demo
111111
111111
openstack role create user
openstack role add --project demo --user demo user
sed -i 's#admin_auth_token# #g' /etc/keystone/keystone-paste.ini
unset OS_AUTH_URL OS_PASSWORD
--------------------------------------------------------------------
作为 admin 用户，请求认证令牌：
openstack --os-auth-url http://controller:35357/v3 \
  --os-project-domain-name default --os-user-domain-name default \
  --os-project-name admin --os-username admin token issue
--------------------------------------------------------------------
作为``demo`` 用户，请求认证令牌：
openstack --os-auth-url http://controller:5000/v3 \
  --os-project-domain-name default --os-user-domain-name default \
  --os-project-name demo --os-username demo token issue

3.3、创建 OpenStack 客户端环境脚本

3.3.1、创建脚本

cat >admin-openrc<<eof
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=111111
export OS_AUTH_URL=http://controller:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
eof

cat > demo-openrc<<eof
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=111111
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
eof

3.3.2、使用脚本

. admin-openrc
openstack token issue

4、镜像服务

mysql -uroot -proot
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance'

openstack user create --domain default --password-prompt glance
111111
111111
openstack role add --project service --user glance admin
openstack service create --name glance \
  --description "OpenStack Image" image
openstack endpoint create --region RegionOne \
  image public http://controller:9292
openstack endpoint create --region RegionOne \
  image internal http://controller:9292
openstack endpoint create --region RegionOne \
  image admin http://controller:9292

4.1、安装配置文件

yum install openstack-glance -y

配置文件：

/etc/glance/glance-api.conf

[database]
mysql+pymysql://glance:glance@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = 111111

[paste_deploy]
flavor = keystone

[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
##############################################
/etc/glance/glance-registry.conf

[database]
connection = mysql+pymysql://glance:glance@controller/glance

[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357

auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = 111111

[paste_deploy]
flavor = keystone

写入镜像服务数据库：

su -s /bin/sh -c "glance-manage db_sync" glance

完成安装

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

4.2、验证操作

使用 `CirrOS`对镜像服务进行验证，CirrOS是一个小型的Linux镜像可以用来帮助你进行 OpenStack部署测试。

. admin-openrc
yum install wget -y
wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
openstack image create "cirros" \
  --file cirros-0.3.5-x86_64-disk.img \

systemctl start neutron-linuxbridge-agent.service

6.3、验证操作

l 注解

在控制节点上执行这些命令。

. admin-openrc
openstack extension list --network

使用网络部分你选择的验证部分来进行部署，网络选项2：自服务网络

输出结果应该包括控制节点上的四个代理和每个计算节点上的一个代理。

openstack network agent list

7、仪表盘

7.1、安装和配置

这个部分将描述如何在控制节点上安装和配置仪表板。

7.2、安全并配置组件

yum install openstack-dashboard -y

/etc/openstack-dashboard/local_settings
OPENSTACK_HOST = "controller"
ALLOWED_HOSTS = ['horizon.example.com', 'localhost','192.168.2.19']

7.3、完成安装

systemctl restart httpd.service memcached.service

访问 http://192.168.2.19/dashboard
admin 111111

排障：
Openstack安装Dashboard之后无法打开页面

[root@controller ~]# cd /var/log/httpd/
[root@controller httpd]# less error_log
[Wed Aug 15 04:55:22.431328 2018] [core:error] [pid 109774] [client 192.168.2.1:9918] Script timed out before returning headers: django.wsgi
[Wed Aug 15 04:56:15.073662 2018] [core:error] [pid 109701] [client 192.168.2.1:9748] End of script output before headers: django.wsgi
修改   /etc/httpd/conf.d/openstack-dashboard.conf  文件
在WSGISocketPrefix run/wsgi下面加一行代码： 
WSGIApplicationGroup %{GLOBAL} 

保存退出，然后重启httpd服务。

8、块存储服务

这个部分描述如何在控制节点上安装和配置块设备存储服务，即 cinder。

这个服务需要至少一个额外的存储节点，以向实例提供卷。

8.1、安装并配置控制节点

mysql -u root -proot
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
exit

openstack user create --domain default --password-prompt cinder
111111
111111
openstack role add --project service --user cinder admin

? 注解 块设备存储服务要求两个服务实体。
openstack service create --name cinderv2   --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3   --description "OpenStack Block Storage" volumev3

? 注解

块设备存储服务每个服务实体都需要端点。

openstack endpoint create --region RegionOne   volumev2 public http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev2 internal http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev2 admin http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 public http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 internal http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 admin http://controller:8776/v3/%\(project_id\)s

8.1.1、安全并配置组件

# ...
transport_url = rabbit://openstack:rabbit@controller
auth_strategy = keystone
my_ip = 192.168.2.19

[keystone_authtoken]
# ...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service

[oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

初始化块设备服务的数据库：

su -s /bin/sh -c "cinder-manage db sync" cinder

8.1.2、配置计算节点以使用块设备存储

vim /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne

8.1.3、完成安装

systemctl restart openstack-nova-api.service
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

8.2、安装并配置一个存储节点

8.2.1、先决条件

l 注解

在存储节点实施这些步骤。

[root@compute1 ~]#
yum install lvm2 -y
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

pvcreate /dev/sda
vgcreate cinder-volumes /dev/sda

　　只有实例可以访问块存储卷组。但是呢，底层的操作系统（如centos）管理着与这些卷相关联的设备。默认情况下，LVM卷扫描工具会对底层操作系统扫描``/dev`` 目录，查找包含卷的块存储设备。

　　如果项目在他们的卷上使用了LVM，LVM卷扫描工具便会在检测到这些块存储卷时尝试缓存它们，这可能会在底层操作系统和项目卷上产生各种问题。所以您必须重新配置LVM，让它扫描仅包含``cinder-volume``卷组的设备。编辑``/etc/lvm/lvm.conf``文件并完成下面的操作：

vim /etc/lvm/lvm.conf
devices {
...
filter = [ "a/sdb/", "r/.*/"]
或者如果sda也是lvm卷的话：
        filter = [ "a/sda/", "a/sdb/", "r/.*/"]

【PS】

centos7默认情况下是创建不了pv的（原因待查证），解决方法如下：

默认：

[root@compute1 ~]# pvcreate /dev/sdb    
  Device /dev/sdb excluded by a filter.

解决：

[root@compute1 ~]# dd if=/dev/urandom of=/dev/sdb bs=512 count=64
64+0 records in
64+0 records out
32768 bytes (33 kB) copied, 0.00760562 s, 4.3 MB/s
[root@compute1 ~]# pvcreate /dev/sdb                             
  Physical volume "/dev/sdb" successfully created.

8.1.3、安全并配置组件

yum install openstack-cinder targetcli python-keystone

vim /etc/cinder/cinder.conf
[database]
# ...
connection = mysql+pymysql://cinder:cinder@controller/cinder
[DEFAULT]
# ...
transport_url = rabbit://openstack:rabbit@controller
auth_strategy = keystone
my_ip=192.168.2.21
enabled_backends = lvm
glance_api_servers = http://controller:9292

[keystone_authtoken]
# ...
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = 111111

如果``[lvm]``部分不存在，则创建它：
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm
[oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

8.1.4、完成安装

systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service

8.2、验证操作

l 注解

在控制节点上执行这些命令。

. admin-openrc
openstack volume service list
