CloudStack 4.4学习总结之cloudstack-agent安装
2、节点安装（cloudstack-agent、KVM）：注：每个Hypervisor上，都要保证【/mnt】目录为空，否则，可能会出现InsufficientServerCapacityException （服务器资源不足）的报错。
cloud-agent-2.perofu.com和cloud-agent-1.perofu.com的安装步骤一样，即，所有cloudstack-agent节点的安装步骤均一样。
下面以cloud-agent-1.perofu.com进行演示。
①、以 root 身份登录并设置主机名：
【cloud-agent-1.perofu.com】
hostname cloud-agent-1.perofu.com
vi /etc/sysconfig/network
HOSTNAME=cloud-agent-1.perofu.com
vi /etc/hosts
127.0.0.1 cloud-agent-1.perofu.com
172.22.2.76 cloud-server.perofu.com
172.22.2.87 cloud-agent-1.perofu.com
172.22.2.100 cloud-agent-2.perofu.com
②、设置SELinux、关闭iptables并同步时间：
vi /etc/sysconfig/selinux
SELINUX=disabled
setenforce 0
service iptables stop
chkconfig iptables off
yum install ntpdate -y
echo '#ntpd' >> /var/spool/cron/root
echo "10 5 * * * /usr/sbin/ntpdate ntp.api.bz &> /dev/null" >> /var/spool/cron/root
echo '' >> /var/spool/cron/root
service ntpd stop
chkconfig ntpd off
/usr/sbin/ntpdate ntp.api.bz &> /dev/null
③、安装Management agent：
V4.4
vi /etc/yum.repos.d/cloudstack.repo
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/rhel/4.4/
enabled=1
gpgcheck=0
yum -y install cloudstack-agent
V3.0
tar -axf CloudStack-oss-3.0.2-1-rhel6.2.tar.gz -C /usr/local/src/
cd /usr/local/src/CloudStack-oss-3.0.2-1-rhel6.2/
./install.sh
A
“A”------> 安装 CloudStack Agent 软件, CloudStack客户端。
④、安装KVM虚拟化环境：
1）、查看CPU是否支持虚拟化：
grep -E -o 'vmx|svm' /proc/cpuinfo
VMX：它是Intel处理器虚拟机技术标志；
SVM：它是AMD处理器虚拟机技术的标志。
注：linux发行版本必须在64bit环境中才能使用KVM。
# grep -E -o 'vmx|svm' /proc/cpuinfo
vmx
2）、安装kvm：
yum源使用的是Centos 6.4的光盘镜像。
yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v libguestfs-tools
3）、修改vnc的监听端口：
vnc默认的监听127.0.0.1。
因为，在创建虚拟机时，需要连接vnc，去手动安装新系统。
cp /etc/libvirt/qemu.conf /etc/libvirt/qemu.conf.bak
vi /etc/libvirt/qemu.conf
vnc_listen=0.0.0.0
4）、配置Libvirt：
vi /etc/libvirt/libvirtd.conf
listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
auth_tcp = "none"
mdns_adv = 0
vi /etc/sysconfig/libvirtd
LIBVIRTD_ARGS="--listen"
service libvirtd restart
chkconfig libvirtd on
5）、检查KVM是否加载成功：
如果没有输出信息，则表示没有加载成功。
lsmod | grep kvm
# lsmod | grep kvm
kvm_intel 534840
kvm 3165061 kvm_intel
6）、检查KVM是否成功安装：
-all关闭的也会显示。
virsh list --all
# virsh list --all
Id Name State
----------------------------------------------------
7）、配置网卡：
虚拟机的网卡名称是：cloudbr0，不要自作聪明，用了br0，报了一个下午的错。
yum install -y tunctl
cat << EOF > /etc/sysconfig/network-scripts/ifcfg-cloudbr0
DEVICE=cloudbr0
TYPE=Bridge
BOOTPROTO=static
IPV6INIT=no
ONBOOT=yes
IPADDR=172.22.2.87
NETMASK=255.255.0.0
GATEWAY=172.22.1.3
DNS1=8.8.8.8
DELAY=0
EOF
cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/bak_ifcfg-eth0
cat << EOF > /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
BRIDGE=cloudbr0
IPV6INIT=no
EOF
/etc/init.d/network restart
#查看桥接网络
brctl show
# ifconfig
cloudbr0 Link encap:EthernetHWaddr 00:0C:29:40:7F:1D

⑤、配置cloudstack-agent：
这里也可以省略，只是在初始化的时候需要手动输入cloudstack-management的ip。
V4.4
vi /etc/cloudstack/agent/agent.properties
# cloudstack管理服务器地址
host= 172.22.2.76
V3.0
vi /etc/cloud/agent/agent.properties
# cloudstack管理服务器地址
host= 172.22.2.76
⑥、配置nfs域名：
vi /etc/idmapd.conf
Domain = perofu.com
⑦、初始化cloudstack-agent：
一路回车，即可。
V4.4
cloudstack-setup-agent
V3.0
cloud-setup-agent
# cloud-setup-agent
Welcome to Cloud Agent Setup:
Please input the Management Server Name/IP:

Please input the Cluster Id:[]
Please choose which network used to create VM:

Configure cloudAgent ...
Cloud Agent setup is Done!
Libvirt报错：
# cloud-setup-agent

Traceback (most recent call last):
File "/usr/bin/cloud-setup-agent", line 112, in <module>
syscfg.config()
File "/usr/lib/python2.6/site-packages/cloudutils/syscfg.py", line 76, in config
raise CloudInternalException()
TypeError: __init__() takes exactly 2 arguments (1 given)
解决：
Libvirt启动失败，端口没看到。
# /etc/init.d/libvirtd restart
Stopping libvirtd daemon:
Starting libvirtd daemon: libcgroup initialization failed: Cgroup is not mounted
yum list libcgroup -y
vi /etc/cgconfig.conf
group virt {
cpu {
cpu.shares = 9216;
}
}
/etc/init.d/cgconfig restart
/etc/init.d/libvirtd restart
chkconfig cgconfig on
⑧、启动cloud-agent：
这里，不需要手动启动cloud-agent，当在manager上创建主机时，manager会自动启动cloud-agent的。
/etc/init.d/cloud-agent start
启动失败啊.

⑨、卸载并清空/mnt目录：
一定要保证/mnt目录没有被使用，且目录为空，否则CloudStack无法对其挂载Primary Storage，新建实例，可能会失败，除非你有多个agent，/mnt已有的数据，请提前保存好。
umount /mnt
rm -rf /mnt/*
⑩、等待加入cloudstack：
到此cloudstack-agent就配置完成了，现在的cloudstack-agent可以在创建区域时加入，也可以在创建完区域后，手动加入，后面均有介绍。
