复制提示
一。KVM虚拟化
1.KVM的安装：
yum install qemu-kvm qemu-kvm-tools virt-manager libvirt virt-install
/etc/init.d/libvirtd start
2.创建一个5G的大小的虚拟机：
qemu-img create -f raw /opt/centos-6.5-x86_64.raw 5G
3.查看虚拟机空间使用大小：
qemu-img info /opt/centos-6.5-x86_64.raw
4.启动虚拟机，并指定内存512，磁盘位置，和CDROM的位置，并启动VNC。
virt-install --virt-type kvm --name centos-6.6-64 --ram 512 --cdrom=/opt/centos-6.5.iso --disk path=/opt/centos-6.5-x86_64.raw --network network=default --graphics vnc,listen=0.0.0.0 --noautoconsole --os-type=linux --os-variant=rhel6
5.使用VNC访问虚拟机：
172.16.2.210 5900端口 （第一台虚拟机默认是5900，第二台就是5901）
6.查看所有创建的虚拟机：
virsh list --all
7.启动虚拟机virsh start centos-6.6-64：
virsh start centos-6.6-64
7.1.直接进入虚拟机命令行：
virsh console centos-6.6-64
8.查看xml文件：
vim /etc/libvirt/qemu/centos-6.6-64.xml
virsh edit centos-6.6-64 （修改xml文件，不能直接用vim修改）
9.根据xml文件新建虚拟机：
virsh define /opt/centos-6.6-64.xml
10.虚拟机监控命令：virt-top
11.查看虚拟网桥状态：brctl show
12.创建桥接网卡并且关联到eth0上面：
brctl addbr br0
brctl addif br0 eth0 && ip del dev eth0 172.16.1.210/24 && ifconfig br0 172.16.1.210/24 up
（创建了桥接网卡以后需要把原来的eth0的IP去掉，把原来的IP配置在br0上面）
13。修改虚拟机的网卡为刚才创建的桥接网卡：
virsh edit centos-6.6-64 （修改虚拟机xml文件）
- <interface type='bridge'>
- <mac address='52:54:00:e4:46:c7'/>
- <source bridge='br0'/>
- <model type='virtio'/>
virsh destroy entos-6.6-64 (关闭在启动虚拟机生效) virsh start entos-6.6-64
二。OPENSTACK 云计算与虚拟化 （I 版）
1.安装Openstack基础环境：
- wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm (下载epel源)
- rpm -ivh epel-release-latest-6.noarch.rpm
- yum install -y python-pip gcc gcc-c++ make libtool patch automake python-devel libxslt-devel MySQL-python openssl-devel libudev-devel git wget libvirt-python libvirt qemu-kvm gedit python-numdisplay python-eventlet device-mapper bridge-utils libffi-devel libffi
2.安装mysql，并且在my.cnf里面加上配置。
- default-storage-engine = innodb
- innodb_file_per_table
- collation-server = utf8_general_ci
- init-connect = 'SET NAMES utf8'
- character-set-server = utf8
3.给openstack创建Mysql相关库。
- create database keystone;
- grant all on keystone.* to keystone@'172.16.0.0/255.255.0.0' identified by 'keystone';（改权限和限制访问的Ip段）
- create database glance;
- grant all on glance.* to glance@'172.16.0.0/255.255.0.0' identified by 'glance';
- create database nova;
- grant all on nova.* to nova@'172.16.0.0/255.255.0.0' identified by 'nova';
- create database neutron;
- grant all on neutron.* to neutron@'172.16.0.0/255.255.0.0' identified by 'neutron';
- create database cinder;
- grant all on cinder.* to cinder@'172.16.0.0/255.255.0.0' identified by 'cinder';
4.安装rabbitmq消息队列：
yum install rabbitmq-server
5.安装rabbitmq的web管理插件：
cd /usr/lib/rabbitmq/bin
./rabbitmq-plugins enable rabbitmq_management
/etc/init.d/rabbitmq-server restart
./rabbitmq-plugins list (检查插件是否正常安装)
http://172.16.1.210:15672 （通过这个网址访问，默认账号密码都是guest）
二。认证服务keystone相关(5000,35357)
6.配置openstack的官方安装源：
- [openstack]
- name=openstack
- baseurl=http://repos.fedorapeople.org/repos/openstack/EOL/openstack-icehouse/epel-6
- enabled=1
- gpgcheck=0
- gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
7.安装openstack-keystone:
yum install openstack-keystone python-keystoneclient
8.创建PKI的目录给keystone使用：
keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
chown -R keystone:keystone /etc/keystone/ssl
chmod -R o-rwx /etc/keystone/ssl (删掉其他用户的权限)
9.修改keystone的配置文件：
vim /etc/keystone/keystone.conf
- admin_token=ADMIN
- log_file=/var/log/keystone/keystone.log
- connection=mysql://keystone:keystone@172.16.1.210/keystone
10.初始化keystone的数据库表结构：
keystone-manage db_sync （没有报错就是成功，最好在进mysql里面show tables看下）
rm /var/log/keystone/keystone.log (不操作会权限报错)
11.启动keystone:
/etc/init.d/openstack-keystone start
12.配置连接keystone连接需要的环境变量：
export OS_SERVICE_TOKEN=ADMIN
export OS_SERVICE_ENDPOINT=http://172.16.1.210:35357/v2.0
13.初始化话keystone的用户数据(admin,demo)：
创建admin,demo用户，创建admin角色，创建service,admin租户
- keystone user-create --name=admin --pass=admin --email=admin@example.com
- keystone role-create --name=admin
- keystone tenant-create --name=admin --description="Admin Tenant"
- keystone user-role-add --user=admin --tenant=admin --role=admin

创建完成后，使用keystone user-list 命令查看是否有admin和demo两个账号
14.查看admin的token
unset OS_SERVICE_TOKEN
unset OS_SERVICE_ENDPOINT
keystone --os-username=admin --os-password=admin --os-tenant-name=admin --os-auth-url=http://172.16.1.210:35357/v2.0 token-get
15.创建admin和demo用户的环境变量文件：
vim /root/keystone-admin
- export OS_TENANT_NAME=admin
- export OS_USERNAME=admin
- export OS_PASSWORD=admin
- export OS_AUTH_URL=http://172.16.1.210:35357/v2.0

/etc/init.d/httpd start
4.登录dashboard：
http://172.16.1.210/dashboard/
默认账户密码：admin/admin
八。调试Openstack
1.为demo创建一个单一扁平网络：
neutron net-create --tenant-id 9d18b0a337064af386cc0d599dd172fd flat_net --shared --provider:network_type flat --provider:physical_network physnet1
id为keystone tenant-list 查看的demo_id, flat_net是创建网络的名称，--shared代表共享网络，后面是网络的类型，最后是对应neutron网络名称.
2.查看创建的网络：
neutron net-list
3.在网页上面创建子网：
管理员-网络-点击网络-创建子网-扁平网络网段就用和eth0一样的就可以
4.虚拟机创建流程图：
5.安装备注：
1.如果安装完成以后虚拟机无法ping同外网，请检查网卡是否打开“混杂模式”
2.强行修改虚拟机的状态为“运行”
nova reset-state 6986b3f8-be2c-4931-b3b9-90d8077210b6 --active
3.启动“主机集合”功能需要修改配置文件：
/etc/nova/nova.conf
scheduler_default_filters=AvailabilityZoneFilter,RetryFilter,RamFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,CoreFilter
4.将db4加入到gigold-2的主机集合里面：
nova aggregate-add-host gigold-2 db4
nova aggregate-remove-host gigold-2 db4 （这个是删除）
5.关闭默认的virbr0虚拟网卡
- virsh net-destroy default
- virsh net-undefine default
- service libvirtd restart
- 大小: 386.1 KB
- 大小: 214.9 KB

- cinder type-key NFS set volume_backend_name=Nfs-Storage
5.下面可以通过网页的云硬盘操作了。
四。块存储服务Cinder存储节点（glusterfs）
1.安装glusterfs服务(两个存储节点都装上)：
- wget http://download.gluster.org/pub/gluster/glusterfs/3.7/3.7.14/CentOS/glusterfs-epel.repo
- mv glusterfs-epel.repo /etc/yum.repos.d/
- yum install glusterfs-server
2.启动两台机器的glusterfs:
/etc/init.d/glusterd start
3.创建glusterfs劵:
- mkdir /data/glusterfs/exp1 (两台机器都要操作)
- gluster peer probe 172.16.1.211 （创建对等节点,在210上面操作）
- gluster volume create cinder-volume01 replica 2 172.16.1.210:/data/glusterfs/exp1 172.16.1.211:/data/glusterfs/exp1 force （创建cinder-volume01劵）
- gluster vol start cinder-volume01 （启动卷）
- gluster vol info （查看劵的状态）
4.修改cinder配置文件：
vim /etc/cinder/glusterfs_shares (本来没有，需要创建)
172.16.1.210:/cinder-volome01
vim /etc/cinder/cinder.conf
- volume_backend_name=GLS-Storage
- glusterfs_shares_config=/etc/cinder/glusterfs_shares
- volume_driver=cinder.volume.drivers.glusterfs.GlusterfsDriver
5.创建cinder的glusterfs类型:
- cinder type-create GLS
- cinder type-key GLS set volume_backend_name=GLS-Storage
6.现在可以到网页上面创建云硬盘了

一。负载均衡服务LBaas
1.在dashboard中打开lbaas菜单：
- 'enable_lb': True,
- 'enable_firewall': True,
- 'enable_quotas': True,
- 'enable_vpn': True,
- 将原来的False改为True.(注意大写)
2.重启dashboard服务：
/etc/init.d/httpd restart
3.安装 haproxy服务：
yum install haproxy
4.修改neutron的配置文件：
vim /etc/neutron/lbaas_agent.ini
- interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver
- device_driver = neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver
- user_group = haproxy
5.安装namespace支持：
ip netns list （输入命令没有报错说明支持，不要在安装了）
yum update iproute
6.修改启动lbaas脚本：
vim /etc/init.d/neutron-lbaas-agent
- configs=(
- "/etc/neutron/neutron.conf" \
- "/etc/neutron/lbaas_agent.ini" \
- )
7.启动lbaas服务：
/etc/init.d/neutron-lbaas-agent start
8.下面可以在WEB界面添加负载均衡了
