systemctl restart httpd.service memcached.service

浏览器访问cotroller ip/dashboard访问仪表盘
验证使用 admin 或者demo用户凭证和default域凭证

可以在左侧计算–>云主机中操作之前创建的云主机

启动之后，点击控制台即可查看

点击右上角退出admin用户，登陆demo用户

在控制节点和计算节点配置私有网络

控制节点

vim /etc/neutron/neutron.conf 

vim /etc/neutron/plugins/ml2/ml2_conf.ini

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

vim /etc/neutron/l3_agent.ini 

systemctl restart neutron-server.service \
  neutron-linuxbridge-agent.service neutron-dhcp-agent.service \
  neutron-metadata-agent.service
systemctl enable neutron-l3-agent.service
systemctl start neutron-l3-agent.service

计算节点

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini 

systemctl restart neutron-linuxbridge-agent.service

控制节点

vim /etc/openstack-dashboard/local_settings 

systemctl restart httpd.service memcached.service

使用admin用户删除云主机和provider网络

新建网络

点击进入网络
创建子网

登陆demo用户
创建网络



创建路由

点击router进入编辑在接口中增加接口

查看网络拓扑

创建云主机
使用public网络创建一个云主机

使用private网络创建一个云主机
步骤同vm1，只需修改云主机名和网络即可

查看网络拓扑

绑定浮动ip
点击加号–>分配ip–>关联

查看云主机

制作镜像

qemu-img create -f qcow2 test.qcow2 5G

打开虚拟机图形管理
选择此选项并选则刚才建立的文件

以下为rhel6.5图形化安装过程,需要注意的是将磁盘都分给根分区

配置ip 使用ssh在物理机连接

关闭selinux

vi /etc/sysconfig/selinux 

chkconfig iptables off
chkconfig ip6tables off
/etc/init.d/iptables stop
/etc/init.d/ip6tables stop
rm -f /etc/udev/rules.d/70-persistent-net.rules 

vi /etc/sysconfig/network
NOZEROCONF=yes

vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="dhcp"
ONBOOT="yes"

vi /boot/grub/grub.conf 

vi /etc/yum.repos.d/rhel-source.repo 
[rhel-source]

yum install -y cloud-*
yum install -y dracut-modules-growroot.noarch
yum install -y acpid
chkconfig acpid on
cd /boot/
dracut -f

yum install -y irqbalance.x86_64
chkconfig irqbalance on

物理机

cd /var/lib/libvirt/images/
virt-sysprep -d test
virt-sparsify --compress test.qcow2 /var/www/html/test.qcow2   #压缩，输出到apache默认发布目录

使用admin用户添加镜像
在管理员–>镜像–>创建镜像

创建云主机类型

登陆demo用户
使用刚才新建的镜像和主机类型创建云主机
新建的云主机磁盘为10G，但镜像磁盘为5G，实现了磁盘的拉伸

块存储服务

mysql -p
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'cinder';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'cinder';

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


openstack service create --name cinder \

systemctl restart openstack-nova-api.service

安装并配置一个存储节点

此处由于硬件限制，将存储节点放在控制节点上

yum install lvm2
systemctl start lvm2-lvmetad.service
systemctl enable lvm2-lvmetad.service

虚拟机添加一个20G的虚拟磁盘

pvcreate /dev/vdb
vgcreate cinder-volumes /dev/vdb
vim /etc/lvm/lvm.conf
filter = [ "a/vda/", "a/vdb/", "r/.*/"]

yum install -y openstack-cinder targetcli python-keystone
vim /etc/cinder/cinder.conf 
[DEFAULT]
enabled_backends = lvm
glance_api_servers = http://controller:9292

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

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

验证操作
由于是在控制节点配置的存储节点，所以Host为controller@lvm，此名字和本地解析有关

cinder service-list

使用demo用户在 项目–>卷–>创建云硬盘

管理连接

控制台查看

拉伸云硬盘
在管理连接中
从vm1上分离云硬盘

扩展云硬盘

再次给vm1连接云硬盘

控制台查看vm1
磁盘已变为10G，挂在查看，云硬盘中内容还在
