赶着下班：先把初稿发出来，后期会整理
本文是本人基于真实环境部署一步步整理而来，如有不解可邮件联系我：egonlin4573@gmail.com
本人是基于自定义yum源部署，因而速度很快，如有需要可以邮件联系我，给你发mitaka最新软件包
操作系统：CentOS Linux release 7.2.1511 (Core)
内核：3.10.0-327.el7.x86_64
效果图：
OpenStack mitaka部署
约定：
1.在修改配置的时候，切勿在某条配置后加上注释，可以在配置的上面或者下面加注释
2.相关配置一定是在标题后追加，不要在原有注释的基础上修改
PART1：环境准备
一：
1：每台机器设置固定ip，每台机器添加hosts文件解析，为每台机器设置主机名，关闭firewalld，selinux
/etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.209.115 controller01
172.16.209.117 compute01
172.16.209.119 network02
2.每台机器配置yum源
[mitaka]
name=mitaka repo
baseurl=http://172.16.209.19/mitaka/mitaka-rpms/
enabled=1
gpgcheck=0
3.每台机器
yum makeache && yum install vim && yum update -y
4.ntp服务部署
所有节点：
yum install chrony ntpdate -y
控制节点：
修改配置：
/etc/chrony.conf
server NTP_SERVER iburst
allow 管理网络网段ip/24
同步时间：
ntpdate 0.centos.pool.ntp.org
启服务：
systemctl enable chronyd.service
systemctl start chronyd.service
其余节点：
修改配置：
/etc/chrony.conf
server 控制节点ip iburst
同步时间：
ntpdate 控制节点ip
启服务
systemctl enable chronyd.service
systemctl start chronyd.service
时区不是Asia/Shanghai需要改时区：
# timedatectl set-local-rtc 1 # 将硬件时钟调整为与本地时钟一致, 0 为设置为 UTC 时间
# timedatectl set-timezone Asia/Shanghai # 设置系统时区为上海
其实不考虑各个发行版的差异化, 从更底层出发的话, 修改时间时区比想象中要简单:
# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
验证：
每台机器执行：
chronyc sources
在S那一列包含*号，代表同步成功（可能需要花费几分钟去同步，时间不同步不要往下做）
二：获取软件包
如果使用自定义源，那么下列centos和redhat的操作可以省略
centos：
yum install yum-plugin-priorities -y
yum install centos-release-openstack-mitaka -y
redhat：
yum install yum-plugin-priorities -y
yum install https://rdoproject.org/repos/rdo-release.rpm -y
红帽系统请去掉epel源
yum upgrade
yum install python-openstackclient -y
yum install openstack-selinux -y
三：部署mariadb数据库
控制节点：
yum install mariadb mariadb-server python2-PyMySQL -y
编辑：
/etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 控制节点管理网络ip
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
启服务：
systemctl enable mariadb.service
systemctl start mariadb.service
mysql_secure_installation
四：为Telemetry 服务部署MongoDB
控制节点：
yum install mongodb-server mongodb -y
编辑：/etc/mongod.conf
bind_ip = 控制节点管理网络ip
smallfiles = true
启动服务：
systemctl enable mongod.service
systemctl start mongod.service
五：部署消息队列rabbitmq
控制节点：
yum install rabbitmq-server -y
启动服务：
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service
新建rabbitmq用户密码：
rabbitmqctl add_user openstack che001
为新建的用户openstack设定权限：
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
六：部署memcached缓存（为keystone服务缓存tokens）
控制节点：
yum install memcached python-memcached -y
启动服务：
systemctl enable memcached.service
systemctl start memcached.service
PART2：认证服务keystone部署
一：安装和配置服务
1.建库建用户
mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘localhost‘ \
IDENTIFIED BY ‘che001‘;
GRANT ALL PRIVILEGES ON keystone.* TO ‘keystone‘@‘%‘ \
IDENTIFIED BY ‘che001‘;
flush privileges;
2.yum install openstack-keystone httpd mod_wsgi -y
3.编辑/etc/keystone/keystone.conf
[DEFAULT]
admin_token = che001
[database]
connection = mysql+pymysql://keystone:che001@controller01/keystone
[token]
provider = fernet
4.同步修改到数据库
su -s /bin/sh -c "keystone-manage db_sync" keystone
5.初始化fernet keys
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
6.配置apache服务
编辑：/etc/httpd/conf/httpd.conf
ServerName controller01
编辑：/etc/httpd/conf.d/wsgi-keystone.conf
新增配置
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
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</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
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined
<Directory /usr/bin>
Require all granted
</Directory>
</VirtualHost>
7.启动服务:
systemctl enable httpd.service
systemctl start httpd.service
二：创建服务实体和访问端点
1.实现配置管理员环境变量，用于获取后面创建的权限
export OS_TOKEN=che001
export OS_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3
2.基于上一步给的权限，创建认证服务实体（目录服务）
openstack service create \
--name keystone --description "OpenStack Identity" identity
3.基于上一步建立的服务实体，创建访问该实体的三个api端点
openstack endpoint create --region RegionOne \
identity public http://controller01:5000/v3
openstack endpoint create --region RegionOne \
identity internal http://controller01:5000/v3
openstack endpoint create --region RegionOne \
identity admin http://controller01:35357/v3
三：创建域，租户，用户，角色，把四个元素关联到一起
建立一个公共的域名：
openstack domain create --description "Default Domain" default
管理员：admin
openstack project create --domain default \
--description "Admin Project" admin
openstack user create --domain default \
--password-prompt admin
openstack role create admin
openstack role add --project admin --user admin admin
普通用户：demo
openstack project create --domain default \
--description "Demo Project" demo
openstack user create --domain default \
--password-prompt demo
openstack role create user
openstack role add --project demo --user demo user
为后续的服务创建统一租户service
解释：后面每搭建一个新的服务都需要在keystone中执行四种操作：1.建租户 2.建用户 3.建角色 4.做关联
后面所有的服务公用一个租户service，都是管理员角色admin，所以实际上后续的服务安装关于keysotne
的操作只剩2，4
openstack project create --domain default \
--description "Service Project" service
四：验证操作：
编辑：/etc/keystone/keystone-paste.ini
在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三个地方
移走：admin_token_auth
unset OS_TOKEN OS_URL
openstack --os-auth-url http://controller01:35357/v3 \
--os-project-domain-name default --os-user-domain-name default \
--os-project-name admin --os-username admin token issue
Password:
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Field | Value |
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| expires | 2016-08-17T08:29:18.528637Z |
| id | gAAAAABXtBJO-mItMcPR15TSELJVB2iwelryjAGGpaCaWTW3YuEnPpUeg799klo0DaTfhFBq69AiFB2CbFF4CE6qgIKnTauOXhkUkoQBL6iwJkpmwneMo5csTBRLAieomo4z2vvvoXfuxg2FhPUTDEbw-DPgponQO-9FY1IAEJv_QV1qRaCRAY0 |

| user_id | 8bc9b323a3b948758697cb17da304035 |
+------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
五：新建客户端脚本文件
管理员：admin-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=che001
export OS_AUTH_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
普通用户demo：demo-openrc
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=che001
export OS_AUTH_URL=http://controller01:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
效果：
source admin-openrc
[root@controller01 ~]# openstack token issue
part3：部署镜像服务
一：安装和配置服务
1.建库建用户
mysql -u root -p
CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘localhost‘ \
IDENTIFIED BY ‘che001‘;
GRANT ALL PRIVILEGES ON glance.* TO ‘glance‘@‘%‘ \
IDENTIFIED BY ‘che001‘;
flush privileges;
2.keystone认证操作：
上面提到过：所有后续项目的部署都统一放到一个租户service里，然后需要为每个项目建立用户，建管理员角色，建立关联
. admin-openrc
openstack user create --domain default --password-prompt glance
openstack role add --project service --user glance admin
建立服务实体
openstack service create --name glance \
--description "OpenStack Image" image
建端点
openstack endpoint create --region RegionOne \
image public http://controller01:9292
openstack endpoint create --region RegionOne \
image internal http://controller01:9292
openstack endpoint create --region RegionOne \
image admin http://controller01:9292
3.安装软件
yum install openstack-glance -y
4.修改配置：

net.ipv4.conf.default.rp_filter=0
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1
2.sysctl -p
3.yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y
4.编辑 /etc/neutron/neutron.conf文件
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
[oslo_messaging_rabbit]
rabbit_host = controller01
rabbit_userid = openstack
rabbit_password = che001
[keystone_authtoken]
auth_uri = http://controller01:5000
auth_url = http://controller01:35357
memcached_servers = controller01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = neutron
password = che001
[oslo_concurrency]
lock_path = /var/lib/neutron/tmp
5．编辑 /etc/neutron/plugins/ml2/openvswitch_agent.ini
[ovs]
#下面ip为计算节点数据网络ip
local_ip = 1.1.1.117
#bridge_mappings = vlan:br-vlan
[agent]
tunnel_types = gre,vxlan
l2_population = True
prevent_arp_spoofing = True
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
enable_security_group = True
6．编辑/etc/neutron/plugins/ml2/ml2_conf.ini文件
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vxlan
mechanism_drivers = openvswitch,l2population
extension_drivers = port_security
[ml2_type_flat]
flat_networks = provider
[ml2_type_vxlan]
vni_ranges = 1:1000
[securitygroup]
enable_ipset = True
7.编辑 /etc/nova/nova.conf
[neutron]
url = http://controller01:9696
auth_url = http://controller01:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = che001
8．启动服务
systemctl enable neutron-openvswitch-agent.service
systemctl start neutron-openvswitch-agent.service
systemctl restart openstack-nova-compute.service
part6:部署控制面板dashboard
在控制节点
1.安装软件包
yum install openstack-dashboard -y
2.配置/etc/openstack-dashboard/local_settings
OPENSTACK_HOST = "controller01"
ALLOWED_HOSTS = [‘*‘, ]
SESSION_ENGINE = ‘django.contrib.sessions.backends.cache‘
CACHES = {
‘default‘: {
‘BACKEND‘: ‘django.core.cache.backends.memcached.MemcachedCache‘,
‘LOCATION‘: ‘controller01:11211‘,
}
}
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
OPENSTACK_API_VERSIONS = {
"identity": 3,
"image": 2,
"volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "default"
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"
OPENSTACK_NEUTRON_NETWORK = {
‘enable_router‘: False,
‘enable_quotas‘: False,
‘enable_distributed_router‘: False,
‘enable_ha_router‘: False,
‘enable_lb‘: False,
‘enable_firewall‘: False,
‘enable_vpn‘: False,
‘enable_fip_topology_check‘: False,
}
TIME_ZONE = "UTC"
3.启动服务
systemctl enable httpd.service memcached.service
systemctl restart httpd.service memcached.service
4.验证；
