OpenStack mitaka

23113fff

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:

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


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
[iyunv@controller01 ~]# openstack token issue


part3：部署镜像服务
一：安装和配置服务

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：

interface_driver=neutron.agent.linux.interface.OVSInterfaceDriver
dhcp_driver=neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata=True

9.配置元数据代理。编辑 /etc/neutron/metadata_agent.ini文件:
[DEFAULT]
nova_metadata_ip=controller01
metadata_proxy_shared_secret=che001

10.创建连接
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini


11.启动服务
控制节点：
systemctl restart openstack-nova-api.service
网路节点：
systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service \
neutron-dhcp-agent.service neutron-metadata-agent.service

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service \
neutron-dhcp-agent.service neutron-metadata-agent.service



12.建网桥
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth2


注意，如果网卡数量有限，想用网路节点的管理网络网卡作为br-ex绑定的物理网卡
#那么需要将网络节点管理网络网卡ip去掉，建立br-ex的配置文件，ip使用原管理网ip
ovs-vsctl add-br br-ex
[iyunv@network01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"
[iyunv@network01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"
HWADDR=bc:ee:7b:78:7b:a7
IPADDR=172.16.209.10
GATEWAY=172.16.209.1
NETMASK=255.255.255.0
DNS1=202.106.0.20
DNS1=8.8.8.8
NM_CONTROLLED=no

systemctl restart network
ovs-vsctl add-port br-ex eth0


三：计算节点配置
1. 编辑 /etc/sysctl.conf
net.ipv4.conf.all.rp_filter=0
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；

如果无法ping通，那么退出namespace
ovs-vsctl del-br br-ex
ovs-vsctl del-br br-int
ovs-vsctl del-br br-tun
ovs-vsctl add-br br-int
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth0
systemctl restart neutron-openvswitch-agent.service neutron-l3-agent.service \
