ll /etc/libvirt/qemu/autostart/		#开机启动软链接地址

#配置服务器console：
grubby --update-kernel=ALL --args="console=ttyS0,115200n8"
reboot	重启
virsh console web01		#console实现控制台登录

sysctl -a |grep ipv4|grep ip_forward	#开启内核转发参数
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
sysctl -p	#立即生效

qemu-img info /opt/web01.raw	#查看raw格式的磁盘
qemu-img create -f qcow2 test.qcow2 1G	#创建一块qcow2格式的虚拟磁盘
qemu-img resize test.qcow2 +2G  	#扩容磁盘容量
time qemu-img convert -f raw -O qcow2 test.raw test.qcow2	#转换磁盘格式（raw-->qcow2）

2.快照管理：

virsh snapshot-create-as web02 --name clean_system	#创建快照
virsh snapshot-list web02	#查看快照
virsh snapshot-revert web02 --snapshotname clean_system	#还原快照
virsh snapshot-delete web02 --snapshotname clean_system	#删除快照

3.虚拟机克隆

4.1完整克隆
virt-clone --auto-clone -o web01 -n web02	
4.2手动完整克隆
cp web01.qcow2 web02.qcow2
virsh dumpxml web01 >web02.xml
vim web02.xml
#修改虚拟机的名字

brctl show 	#查看交换设备

4.桥接网卡

5.1创建桥接网卡
virsh iface-bridge eth0 br0
5.2取消桥接网卡
virsh iface-unbridge br0

5.热添加

6.1临时添硬盘
virsh attach-disk web01 /data/web01-add.qcow2 vdb --subdriver qcow2

virsh migrate --live --verbose web03 qemu+ssh://10.0.0.100/system --unsafe --persistent --undefinesource

3.云技术基础架构服务平台搭建

3.1基础环境搭建：

1.准备两台内存为8G的服务器，以及挂载光盘镜像[都做]
1.1全部做hosts解析
10.0.0.11	controller
10.0.0.31	compute1

1.2挂载光盘
mount /dev/cdrom /mnt
echo "mount /dev/cdrom /mnt" >>/etc/rc.local 
chmod +x /etc/rc.local

2.搭建本地Yum仓库[都做]
[root@controller yum.repos.d]# cat openstack.repo 
[openstack]
name=openstack
baseurl=file:///opt/repo
gpgcheck=0

[local]
name=local
baseurl=file:///mnt
gpgcheck=0

3.时间同步
controller节点配置ntp服务端:
vim /etc/chrony.conf
allow 10.0.0.0/24

systemctl restart chronyd
systemctl enable chronyd

4.其他节点配置ntp客户端:
vim /etc/chrony.conf
server 10.0.0.11 iburst
systemctl restart chronyd

5.所有节点安装openstack客户端
yum install python-openstackclient -y

6.控制节点安装数据库并配置
yum install mariadb mariadb-server python2-PyMySQL -y

vi /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 10.0.0.11
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

systemctl start mariadb
systemctl enable mariadb

mysql_secure_installation
先回车,选择N,剩下的一路y

7.控制节点安装消息队列
yum install rabbitmq-server -y

systemctl start rabbitmq-server.service 
systemctl enable rabbitmq-server.service

rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

8.控制节点安装memcache并配置
yum install memcached python-memcached -y

vim /etc/sysconfig/memcached
OPTIONS="-l 0.0.0.0"

systemctl start memcached.service 
systemctl enable memcached.service

9.控制节点安装keystone服务

7.测试 上传一个镜像然后启动实例

4.0安装cinder块存储服务

#了解：
Centos配置iscsi

cinder-api:       接收和响应外部有关块存储请求
cinder-volume：   提供存储空间
cinder-scheduler：调度器，决定将要分配的空间由哪一个cinder-volume提供
cinder-backup：    备份存储

1.创建数据库并授权
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' 
  IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' 
  IDENTIFIED BY 'CINDER_DBPASS';
  
2.创建cinder用户，添加 admin 角色到 cinder 用户上  
openstack user create --domain default --password CINDER_PASS cinder
openstack role add --project service --user cinder admin

3.创建 cinder 和 cinderv2 服务实体
openstack service create --name cinder --description "OpenStack Block Storage" volume
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

4.创建块设备存储服务的 API 入口点
openstack endpoint create --region RegionOne volume public http://controller:8776/v1/%(tenant_id)s
openstack endpoint create --region RegionOne volume internal http://controller:8776/v1/%(tenant_id)s
openstack endpoint create --region RegionOne volume admin http://controller:8776/v1/%(tenant_id)s
openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%(tenant_id)s
openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%(tenant_id)s
openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%(tenant_id)s

安全并配置组件
1.安装软件包 
yum install openstack-cinder -y

2.编辑 /etc/cinder/cinder.conf，同时完成如下动作
cp /etc/cinder/cinder.conf{,.bak}
grep -Ev '^$|#' /etc/cinder/cinder.conf.bak >/etc/cinder/cinder.conf
openstack-config --set /etc/cinder/cinder.conf   DEFAULT  rpc_backend  rabbit
openstack-config --set /etc/cinder/cinder.conf   DEFAULT  auth_strategy  keystone
openstack-config --set /etc/cinder/cinder.conf   DEFAULT  my_ip  10.0.0.11
openstack-config --set /etc/cinder/cinder.conf   database connection mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
openstack-config --set /etc/cinder/cinder.conf   keystone_authtoken   auth_uri  http://controller:5000
openstack-config --set /etc/cinder/cinder.conf   keystone_authtoken   auth_url  http://controller:35357
openstack-config --set /etc/cinder/cinder.conf   keystone_authtoken   memcached_servers  controller:11211

openstack-config --set /etc/cinder/cinder.conf   oslo_messaging_rabbit  rabbit_password  RABBIT_PASS

3.初始化块设备服务的数据库
su -s /bin/sh -c "cinder-manage db sync" cinder

4.编辑文件 /etc/nova/nova.conf [控制节点]
openstack-config --set /etc/nova/nova.conf cinder os_region_name  RegionOne

5.重启计算API 服务，启动块设备存储服务，并将其配置为开机自启【控制节点】
systemctl restart openstack-nova-api.service
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

验证：cinder service-list

6.安装并配置一个存储节点
6.1在计算节点上：
yum install lvm2 -y
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
6.2添加两块盘 30G+10G
echo '- - -' >/sys/class/scsi_host/host0/scan 
fdisk -l
pvcreate /dev/sdb
pvcreate /dev/sdc
vgcreate cinder-ssd /dev/sdb
vgcreate cinder-sata /dev/sdc
6.3修改/etc/lvm/lvm.conf
在130下面插入一行：
filter = [ "a/sdb/", "a/sdc/","r/.*/"]

6.4 安装
yum install openstack-cinder targetcli python-keystone -y

4.2.1cinder对接Glusterfs存储

Glusterfs是一个开源分布式文件系统，具有强大的横向扩展能力，可支持数PB存储容量和数千客户端，通过网络互联成一个并行的网络文件系统。具有可扩展性、高性能、高可用性等特点。

服务端：10.0.0.11    10.0.0.32
客户端：10.0.0.31
1.安装安装服务端
yum -y install glusterfs glusterfs-fuse glusterfs-server

systemctl start glusterd.service
systemctl enable glusterd.service

2.添加存储资源池
compute2操作
gluster peer probe controller
[root@compute2 ~]# gluster pool list
UUID					Hostname  	State
20ca80d7-3ae6-4034-9cc9-ad49b0e81419	controller	Connected 
df81534b-41da-4f1d-b152-73802180a9b3	localhost 	Connected 
[root@compute2 ~]# mkdir /data

3.创建分布式复制卷
gluster volume create gv1 controller:/data compute2:/data/ force

4.启动卷

gluster> volume start gv1
volume start: glusters: success

5.查看卷
[root@compute2 ~]# gluster volume info 
 
Volume Name: gv1
Type: Distribute
Volume ID: 85f64393-702a-4117-8834-cdfdbfb367af
Status: Started
Snapshot Count: 0
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: controller:/data
Brick2: compute2:/data
Options Reconfigured:
nfs.disable: on
transport.address-family: inet


[root@compute2 ~]# systemctl restart openstack-nova-compute.service 

6.客户端挂载卷
[root@compute1 ~]# mkdir /brick1
[root@compute1 ~]# mount.glusterfs compute2:/gv1 /brick1/

yum -y install glusterfs glusterfs-fuse
vim /etc/cinder/cinder.conf
[DEFAULT]
...
enabled_backends = glusterfs
...

[glusterfs]
volume_driver = cinder.volume.drivers.glusterfs.GlusterfsDriver
glusterfs_shares_config = /etc/cinder/glusterfs_shares
volume_backend_name=glusterfs

7.编辑/etc/cinder/glusterfs_shares
[root@compute1 ~]# cat /etc/cinder/glusterfs_shares 
controller:/gv1
compute2:/gv1

systemctl restart openstack-cinder-volume

8.controller节点查看cinder
cinder service-list

9.登录dashboard--->创建卷类型--->创建卷--->管理连接【实例】--->验证
[root@compute1 ~]# ll /brick1/ -h

4.3实例的冷迁移

1.控制节点兼职计算节点
[root@controller ~]# yum install openstack-nova-compute.noarch
vim /etc/nova/nova.conf
[vnc]
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html

systemctl start libvirtd.service openstack-nova-compute.service
主机聚集---》改为controller---->创建实例验证

#迁移操作===================================================================
1：开启nova计算节点之间互信
冷迁移需要nova计算节点之间使用nova用户互相免密码访问
默认nova用户禁止登陆，开启所有计算节点的nova用户登录shell。

usermod -s /bin/bash nova
su - nova
ssh-keygen -t rsa
#生成密钥
cp -fa id_rsa.pub authorized_keys

将公钥发送给其他计算节点的nova用户的/var/lib/nova/.ssh目录下，注意权限和所属组
[nova@compute1 ~]$ scp -rp .ssh root@10.0.0.32:`pwd`
[root@compute2 ~]# chown -R nova:nova /var/lib/nova/.ssh/

2：修改控制节点nova.conf
vim /etc/nova/nova.conf
[DEFAULT]
scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,RamFilter,DiskFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter

重启openstack-nova-scheduler
systemctl restart openstack-nova-scheduler.service

3:修改所有计算节点的nova配置
vi /etc/nova/nova.conf
[DEFAULT]
allow_resize_to_same_host = True

重启openstack-nova-compute
systemctl restart openstack-nova-compute.service

4：dashboard上进行操作---->创建实例---->实现冷迁移操作

4.4cloud-init为云环境中虚拟机的初始化定制【配置元数据代理】

nova-matadata-api
neutron-metadata-agent
配合实现虚拟机定制化

1.编辑``/etc/neutron/metadata_agent.ini``文件并完成以下操作：
在``[DEFAULT]`` 部分，配置元数据主机以及共享密码：  
[root@controller ~]# vim /etc/neutron/metadata_agent.ini
[DEFAULT]
nova_metadata_ip = controller
metadata_prox = METADATA_SECRET

2.为nova服务配置网络服务
编辑``/etc/nova/nova.conf``文件并完成以下操作：
在``[neutron]``部分，配置访问参数，启用元数据代理并设置密码
[neutron]
...
url = http://controller:9696
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = NEUTRON_PASS
service_metadata_proxy = True
metadata_proxy_shared_secret = METADATA_SECRET  

3.重启服务
[root@controller ~]# systemctl restart neutron-server.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-dhcp-agent.service

4.登录dashboard创建实例---->实现定制化启动实例---->验证效果
