Cloudstack安装部署
1.概况
IaaS层统一管理监控平台包括OpenStack，CloudStack等，对于使用大量主机和存储的应用提供了管理平台。
CloudStack是一个开源的具有高可用性及扩展性的云计算平台。
支持管理大部分主流的hypervisors，如KVM，XenServer，VMware，OracleVM，Xen等
1.CloudStack管理网络，存储，主机，支持管理KVM，Xen，VMWare虚拟机。
2.CloudStack是Apache顶级项目，完成与OpenStack类似功能。
3.KVM（kernel-basedVirtualMachine）是基于内核的虚拟机，是基于硬件的完全虚拟化。
2.安装KVM及相关软件
1.1.安装kvm虚拟机
1、KVM需要有CPU的支持（Intelvmx或AMDsvm），在安装KVM之前检查一下CPU是否提供了虚拟技术的支持：
[root@myKVM~]#egrep'^flags.*（vmx|svm）'/proc/cpuinfo
有显示,有显示则说明处理器具有VT功能
2、在主板BIOS中开启CPU的VirtualTechnolege（VT，虚化技术）
3、安装kvm及其需要的软件包
[root@myKVM~]#yuminstallkvmkmod-kvmqemukvm-qemu-imgvirt-viewervirt-managerlibvirtlibvirt-pythonpython-virtinst
或
[root@myKVM~]#yumgroupinstallKVM
4、检查kvm模块是否安装，使用以下命令显示两个模块则表示安装完成
[root@myKVM~]#lsmod|grepkvm
1.2.启动virt-manager管理界面
1、客户端
VNC到服务器端，因为需要用服务器的图形界面
2、服务器端
启动libvirtd服务，并保证下次自动启动
[root@myKVM~]#servicelibvirtdstart
Startinglibvirtddaemon:
[确定]
[root@myKVM~]#chkconfiglibvirtdon
1.3.远程创建和管理KVM虚拟机
1.打开Application=>SystemTools=>VirtualMachineManager就可以装虚拟机了，功能跟VMware类似
3.安装cloudstack环境
构建安装包
#yumgroupinstall"DevelopmentTools"

4.配置cloudstack环境
4.1.配置基础环境
通过bbb:
//lnxcs01:
8080/client/配置infrasructure中的zone，pod，cluster
4.2.安装cloud-agent
在同一台机器上安装cloud-client和client-agent（KVM主机和cloud管理在一台机器上）
#yuminstallcloud-agent
通过命令将host添加到cloudstackmanagement中。
如果出现unabletoaddtohost错误，查看一下网络，新增加一个文件
vi/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0#网卡的名称
#TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BRIDGE=virbr0
vi/etc/sysconfig/network-scripts/ifcfg-virbr0
DEVICE=virbr0#网桥的名称，这是CloudStack默认的网桥名称
TYPE=Bridge#设备类型为网桥
ONBOOT=yes
BOOTPROTO=static#使用静态IP，注意在ifcfg-p4p1中不写ip，网桥的配置文件中才写
IPADDR=192.168.122.1#IP位置，根据自己的网络情况配置
BROADCAST=192.168.122.255#广播位置，根据自己的网络情况配置
NETMASK=255.255.255.0#子网掩码，根据自己的网络情况配置
GATEWAY=10.192.17.254#网关位置，根据自己的网络情况配置
DNS1=10.192.1.1#DNS服务器位置，根据自己的网络情况配置
况配置
确保配置文件正确后，关闭NetworkManager服务
>#serviceNetworkManagerstop
你可以看到右上角网络的图标消失了，之后重启网络服务
>#servicenetworkreload
>#serviceNetworkManagerstart
#cloudstack-setup-agent
cloud-setup-agent然后根据要求写MSip，zoneid，podid，clu
