规划：Cloudstack 3.0.5+CentOS6.3 x86_64+KVM平台
| 主机名称 | management.example.com | agent-1.example.com |
| ip地址 | 192.168.1.250 | 192.168.1.251 |
| 用途 | cloud-management+NFS | KVM+Agent |
1、CPU虚拟化支持验证（KVM的要求）
[root@management ~]# grep vmx /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt aes xsave avx lahf_lm ida arat epb xsaveopt pln pts dts tpr_shadow vnmi flexpriority ept vpid
-----否则，cpu不支持或是主板BIOS的虚拟化支持没有打开。另外KVM需要linux是x86_64架构的。
2、配置网卡（本示例中使用的eth1，因为eth0网卡有问题）
[root@management ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
3、上面关闭了NM_CONTROLLED，开启network服务
[root@management ~]#chkconfig network on
[root@management ~]#service network restart
4.修改/etc/yum.conf文件，使yum保存缓存
[root@management ~]# vi /etc/yum.conf
keepcache=1
5.修改主机名称并验证
[root@management ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=management.example.com
~
[root@management ~]# vi /etc/hosts (规划时有多少主机IP对应的写多少)
192.168.1.250 management.example.com
192.168.1.251 agent-1.example.com
[root@management ~]# hostname --fqdn
Management.example.com
注意：如果此时查询时没有返回正确的长格式名称，可能需要重启linux服务器。
6、重启network服务
[root@management ~]# service network restart
7、安装NTP服务并配置
[root@management ~]# yum install ntp -y
[root@management ~]# chkconfig ntpd on
[root@management ~]# vi /etc/ntp.conf
#server 0.centos.pool.ntp.org 22行首加“#”，注释改行
#server 1.centos.pool.ntp.org 23行首加“#”，注释改行
#server 2.centos.pool.ntp.org 24行首加“#”，注释改行
server 127.127.1.0 # local clock 35行去掉行首“#”
fudge 127.127.1.0 stratum 10 36行去掉行首“#”
[root@management ~]# service ntpd restart
Shutting down ntpd: [ OK ]
Starting ntpd: [ OK ]
8、清空防火墙
[root@management ~]# iptables -F
[root@management ~]# service iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables: [ OK ]
9、关闭SElinux
[root@management ~]# vi /etc/selinux/config
SELINUX=permissive
[root@management ~]# setenforce 0
[root@management ~]# getenforce
Permissive
10、上传cloudstack 安装包和kvm用的系统模板
[root@management ~]# ls

Starting to configure CloudStack Management Server:
Configure sudoers ... [OK]
Configure Firewall ... [OK]
Configure CloudStack Management Server ...[OK]
CloudStack Management Server setup is Done!
17、查看cloud-management服务状态
[root@management CloudStack-3.0.5-1-rhel6.2]# service cloud-management status
cloud-management (pid 30417) is running...
18、安装并配置NFS服务
[root@management CloudStack-3.0.5-1-rhel6.2]# yum install nfs-utils -y
19、产看当前磁盘使用情况(可以注意到/home目录的空间最大，此处我们用于nfs共享)
[root@management CloudStack-3.0.5-1-rhel6.2]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_management-lv_root
50G 4.1G 43G 9% /
tmpfs 16G 260K 16G 1% /dev/shm
/dev/sda1 485M 37M 423M 9% /boot
/dev/mapper/vg_management-lv_home
1.3T 198M 1.3T 1% /home
20、/home目录权限如下
[root@management CloudStack-3.0.5-1-rhel6.2]# ll -d /home/
drwxr-xr-x. 3 root root 4096 Sep 23 2011 /home/
21、建立主存储和二级存储目录
[root@management CloudStack-3.0.5-1-rhel6.2]# mkdir -p /home/storage/primary
[root@management CloudStack-3.0.5-1-rhel6.2]# mkdir -p /home/storage/secondary
----注意：本示例中的磁盘划分不是很合理，最好是能为/storage单独做个分区
22、配置nfs的共享目录
[root@management CloudStack-3.0.5-1-rhel6.2]# vi /etc/exports
添加如下两行：
/home/storage/primary *(rw,async,no_root_squash)
/home/storage/secondary *(rw,async,no_root_squash)
~
22、NFSv4要求所有客户端的域设置匹配
[root@management CloudStack-3.0.5-1-rhel6.2]# vi /etc/idmapd.conf
Domain = example.com #（本示例中域名是 example.com）
23、配置nfs
[root@management CloudStack-3.0.5-1-rhel6.2]# vi /etc/sysconfig/nfs
取消下面各行行首的“#”，取消注释
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020
24、nfs服务的启动
[root@management CloudStack-3.0.5-1-rhel6.2]# chkconfig rpcbind on
[root@management CloudStack-3.0.5-1-rhel6.2]# service rpcbind restart
Stopping rpcbind: [ OK ]
Starting rpcbind: [ OK ]
[root@management CloudStack-3.0.5-1-rhel6.2]# chkconfig nfs on
[root@management CloudStack-3.0.5-1-rhel6.2]# service nfs restart

Export list for 192.168.1.250:
/home/storage/secondary *
/home/storage/primary *
25、挂在二级存储
[root@management CloudStack-3.0.5-1-rhel6.2]# mount -t nfs 192.168.1.250:/home/storage/secondary /opt
26、上传kvm系统模板
[root@management CloudStack-3.0.5-1-rhel6.2]# /usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt -m /opt -f /root/acton-systemvm-02062012.qcow2.bz2 -h kvm -F
返回结果：
Successfully installed system VM template /root/acton-systemvm-02062012.qcow2.bz2 to /opt/template/tmpl/1/3/
27、卸载二级存储
[root@management CloudStack-3.0.5-1-rhel6.2]# umount /opt
28、重启cloud-management服务
[root@management CloudStack-3.0.5-1-rhel6.2]# service cloud-management restart
Stopping cloud-management:[ OK ]
Starting cloud-management: [ OK ]
29、在浏览器（最好使用火狐，IE下访问有BUG）输入 http：//serverIP：8080/client
默认账户：admin
密码：password
30、本示例中选中“我以前使用过cloudstack，跳过该指南”
注意：此时我们还没有安装agent端
31、进入界面后的全局概览
32、选中“基础架构”用以查看当前状态
、选中“全局设置”
、搜索关键字“secstorage”并修改如下所示的参数值
、设置二级存储的NFS所在网段并确认
36、选中“close”
37、搜索关键字“cidr”并查看管理端serverIP是否在“management.netword.cidr”的网段内
38、搜索关键字“expunge”，并修改 “expunge.delay”和“expunge.interval”两个的值
39、选项值设置完成
40、在management 服务器端重启cloud-management服务
[root@management ~]# service cloud-management restart
Stopping cloud-management:[ OK ]
Starting cloud-management: [ OK ]
第二部分、cloud agent端的安装配置1、验证agent服务器支持虚拟化指令集

5.配置/etc/hosts名称解析文件
[root@agent-1 ~]# vi /etc/hosts
添加如下内容：
192.168.1.251 agent-1.example.com
~
6、验证主机的长格式名称
[root@agent-1 ~]# hostname --fqdn
agent-1.example.com
7、验证ntp服务是否安装
[root@agent-1 ~]# rpm -qa ntp
ntp-4.2.4p8-2.el6.centos.x86_64
8、配置ntp时间服务
[root@agent-1 ~]# grep -v "^#" /etc/ntp.conf
driftfile /var/lib/ntp/drift
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery
restrict 127.0.0.1
