openstack pike如何安裝

小編給大家分享一下openstack pike如何安裝，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

節點規劃
準備4臺虛機，分別做Controller,Network,Compute,Middleware。
Controller安裝keystone,glance,nova-api,nova-conductor,nova-scheduler,nova-placement
Network安裝neutron相關組件
Compute安裝nova-compute
Middleware安裝mariadb,rabbitmq,memcache。
網絡規劃
controller
  eth0: 192.168.100.111 external
  eth2: 10.1.1.1 admim
network 
  eth0: 192.168.100.114 external
  eth2: 10.1.1.4 admin
  eth3: 10.2.2.4 tunnel
compute
  eth0: 192.168.100.112 external
  eth2: 10.1.1.2 admin
  eth3: 10.2.2.2 tunnel
middleware (mysql,mq,memcache)
  eth2: 10.1.1.3 admin
基礎配置
每個節點都按如下操作
hosts文件
echo "
10.1.1.1 controller
10.1.1.2 compute
10.1.1.3 middleware
10.1.1.4 network
" >>/etc/hosts
配置yum源
yum install -y  wget
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install centos-release-openstack-pike -y
yum clean all && yum makecache
時間同步
echo "*/3 * * * * /usr/sbin/ntpdate ntp6.aliyun.com  &> /dev/null" > /tmp/crontab
crontab /tmp/crontab
Middleware節點
安裝數據庫
yum install -y mariadb-server 
systemctl restart mariadb.service
systemctl enable mariadb.service
安裝rabbitmq
yum install -y erlang rabbitmq-server
systemctl restart rabbitmq-server 
systemctl enable rabbitmq-server
創建openstack用戶，并設置密碼
rabbitmqctl add_user openstack 123456
給openstack用戶賦予權限
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
rabbitmqctl set_user_tags openstack administrator
rabbitmqctl list_users
打開RabbitMQ相關插件
/usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent
查看RabbitMQ插件
/usr/lib/rabbitmq/bin/rabbitmq-plugins list
安裝memcached
yum install -y memcached python-memcached
配置memcache監聽端口
sed -i  's/OPTIONS*.*/OPTIONS="-l 127.0.0.1,10.1.1.3"/' /etc/sysconfig/memcached
重啟memcache并設置開機啟動
systemctl restart memcached.service
systemctl enable memcached.service
systemctl status memcached.service


Controller節點
安裝keystone
yum  -y install openstack-keystone httpd mod_wsgi python-openstackclient openstack-utils  
創建keystone庫，并給keystone用戶授權
create database keystone;
grant all privileges on keystone.* to 'keystone'@'localhost' identified by '123456';
grant all privileges on keystone.* to 'keystone'@'%' identified by '123456';
配置/etc/keystone/keystone.conf 
 cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak
 > /etc/keystone/keystone.conf

 openstack-config --set /etc/keystone/keystone.conf DEFAULT transport_url rabbit://openstack:123456@middleware
 openstack-config --set /etc/keystone/keystone.conf database connection mysql://keystone:123456@middleware/keystone
 openstack-config --set /etc/keystone/keystone.conf cache backend oslo_cache.memcache_pool
 openstack-config --set /etc/keystone/keystone.conf cache enabled true
 openstack-config --set /etc/keystone/keystone.conf cache memcache_servers middleware:11211
 openstack-config --set /etc/keystone/keystone.conf memcache servers middleware:11211
 openstack-config --set /etc/keystone/keystone.conf token expiration 3600
 openstack-config --set /etc/keystone/keystone.conf token provider fernet
配置httpd.conf文件
 sed  -i  "s/ServerName www.example.com:80/ServerName controller/" /etc/httpd/conf/httpd.conf
配置keystone與httpd結合
 ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
建立identity表結構
su -s /bin/sh -c "keystone-manage db_sync" keystone
初始化fernet
keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
啟動httpd，并設置httpd開機啟動
 systemctl enable httpd.service
 systemctl restart httpd.service
 systemctl status httpd.service
創建admin用戶角色

keystone-manage bootstrap --bootstrap-password 123456 --bootstrap-admin-url http://controller:35357/v3 --bootstrap-internal-url http://controller:35357/v3 --bootstrap-public-url http://controller:5000/v3 --bootstrap-region-id RegionOne --bootstrap-username admin --bootstrap-project-name admin --bootstrap-role-name admin --bootstrap-service-name keystone

驗證

openstack project list --os-username admin --os-project-name admin --os-user-domain-id default --os-project-domain-id default --os-identity-api-version 3 --os-auth-url http://controller:5000 --os-password 123456

創建admin用戶環境變量，創建/root/admin-openrc 文件
cat >> /root/admin-openrc <<eof
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_DOMAIN_ID=default
export OS_USERNAME=admin
export OS_PROJECT_NAME=admin
export OS_PASSWORD=123456
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2
export OS_AUTH_URL=http://controller:35357/v3
EOF
創建service項目
 source /root/admin-openrc
 openstack project create --domain default   --description "Service Project" service
創建demo項目
 openstack project create --domain default   --description "Demo Project" demo
創建demo用戶,并設置密碼
 openstack user create --domain default  demo  --password 123456
創建user角色并將demo用戶賦予user角色
 openstack role create user
 openstack role add --project demo --user demo user
驗證keystone

unset OS_TOKEN  OS_URL
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 --os-password 123456

創建硬鏈接
 ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini
同步數據庫,初始化neutron表結構
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf   --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
在controller上重啟nova服務
 systemctl restart openstack-nova-api.service
 systemctl status openstack-nova-api.service
重啟neutron服務并設置開機啟動
 systemctl enable neutron-server.service  neutron-linuxbridge-agent.service neutron-dhcp-agent.service  neutron-metadata-agent.service neutron-l3-agent.service
 systemctl restart neutron-server.service  neutron-linuxbridge-agent.service  neutron-dhcp-agent.service  neutron-metadata-agent.service neutron-l3-agent.service

openstack network agent list
創建網絡
執行環境變量
 source /root/admin-openrc
創建flat模式的public網絡，public是外出網絡，必須是flat模式的
 neutron net-create --shared provider --router:external True --provider:network_type flat --provider:physical_network provider
本實驗環境192.168.100.0/24網段可以出外網，就以該網段作為public網段
創建子網
neutron subnet-create provider 192.168.100.0/24 --name provider-sub  --allocation-pool start=192.168.100.180,end=192.168.100.190 --dns-nameserver 8.8.8.8 --gateway 192.168.100.180
創建名為private的私有網絡, 網絡模式為vxlan
 neutron net-create private --provider:network_type vxlan --router:external False --shared
創建名為private-subnet的私有網絡子網，網段為172.17.1.0, 這個網段就是虛擬機獲取的私有的IP地址
neutron subnet-create private --name private-subnet --gateway 172.17.1.1  172.17.1.0/24
也可以創建多個不同的私有子網絡
如果虛機要能夠訪問外部網絡還需要添加路由
添加路由
neutron router-create router01
將私有網絡的子網加入路由  
neutron router-interface-add router01 private-sub  
設置public網絡為路由的網關
neutron router-gateway-set router01 provider

創建實例


一次選擇“源”->"實例類型"->"網絡" 點擊創建實例
創建一個名為test的實例，上圖中的test1是為了驗證創建過程新建的實例，test是已經創建的實例


實例有了，也分配了IP，此時的實例就可以出外網了，因為前面已經創建了provider網絡，但外網還是不能進來，因為沒有綁定浮動IP。
分配floatingip


浮動IP關聯





創建安全組
