首先我们得有一个pacemaker的环境，需要三台机器，如果没有那么多物理机器，可以用kvm虚拟机
创建一个bridge
ovs-vsctl add-br ubuntu_br
ifconfig ubuntu_br 192.168.100.1/24
在Host上设置NAT，并且enable ip forwarding
# sysctl -p
net.ipv4.ip_forward = 1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
创建虚拟机镜像
我们有一个干净的ubuntu的image，基于它创建一个镜像
qemu-img create -f qcow2 -o backing_file=./ubuntu-14.04.img ./pacemaker01.img
创建一个xml文件，将虚拟机网卡attach到ubuntu_br上面
# cat pacemaker01.xml

定义并启动虚拟机
virsh define pacemaker01.xml
virsh start Pacemaker01
用VNC登录虚拟机，进行网络配置

重启虚拟机，应该可以进行apt-get update了
同样配置另外两台机器。
首先是安装
apt-get install pacemaker corosync

启动corosync
nohup corosync -f > corosync.log 2>&1 &
使用下面的命令查看corosync是否配置得当
root@pacemaker01:/etc/corosync# corosync-cfgtool -s -a
Printing ring status.
Local node ID 1084777482
RING ID 0

ip_start调用add_interface $OCF_RESKEY_ip $NETMASK $BRDCAST $NIC $IFLABEL
add_interface中执行下面的命令
$IP2UTIL -f inet addr add $ipaddr/$netmask brd $broadcast dev $iface

root@pacemaker01:~# crm ra info ocf:heartbeat:IPaddr2
Manages virtual IPv4 addresses (Linux specific version) (ocf:heartbeat:IPaddr2)
Manages virtual IPv4 addresses (Linux specific version) (ocf:heartbeat:IPaddr2)
This Linux-specific resource manages IP alias IP addresses.
It can add an IP alias, or remove one.
In addition, it can implement Cluster Alias IP functionality
if invoked as a clone resource.
If used as a clone, you should explicitly set clone-node-max >= 2,
and/or clone-max < number of nodes. In case of node failure,
clone instances need to be re-allocated on surviving nodes.
Which would not be possible, if there is already an instance on those nodes,
and clone-node-max=1 (which is the default).
Parameters (* denotes required, [] the default):
ip* (string): IPv4 address
The IPv4 address to be configured in dotted quad notation, for example
"192.168.1.1".
nic (string): Network interface
The base network interface on which the IP address will be brought
online.
If left empty, the script will try and determine this from the
routing table.
Do NOT specify an alias interface in the form eth0:1 or anything here;
rather, specify the base interface only.
If you want a label, see the iflabel parameter.
Prerequisite:
There must be at least one static IP address, which is not managed by
the cluster, assigned to the network interface.
If you can not assign any static IP address on the interface,
modify this kernel parameter:
sysctl -w net.ipv4.conf.all.promote_secondaries=1 # (or per device)
cidr_netmask (string): CIDR netmask
The netmask for the interface in CIDR format
(e.g., 24 and not 255.255.255.0)
If unspecified, the script will also try to determine this from the
routing table.
broadcast (string): Broadcast address
Broadcast address associated with the IP. If left empty, the script will
determine this from the netmask.
iflabel (string): Interface label
You can specify an additional label for your IP address here.
This label is appended to your interface name.
If a label is specified in nic name, this parameter has no effect.
lvs_support (boolean, [false]): Enable support for LVS DR
Enable support for LVS Direct Routing configurations. In case a IP
address is stopped, only move it to the loopback device to allow the
local node to continue to service requests, but no longer advertise it
on the network.
mac (string): Cluster IP MAC address
Set the interface MAC address explicitly. Currently only used in case of
the Cluster IP Alias. Leave empty to chose automatically.
clusterip_hash (string, [sourceip-sourceport]): Cluster IP hashing function
Specify the hashing algorithm used for the Cluster IP functionality.
unique_clone_address (boolean, [false]): Create a unique address for cloned instances
If true, add the clone ID to the supplied value of ip to create
a unique address to manage
arp_interval (integer, [200]): ARP packet interval in ms
Specify the interval between unsolicited ARP packets in milliseconds.
arp_count (integer, [5]): ARP packet count
Number of unsolicited ARP packets to send.
arp_bg (string, [true]): ARP from background
Whether or not to send the arp packets in the background.
arp_mac (string, [ffffffffffff]): ARP MAC
MAC address to send the ARP packets to.
You really shouldn‘t be touching this.
flush_routes (boolean, [false]): Flush kernel routing table on stop
Flush the routing table on stop. This is for
applications which use the cluster IP address
and which run on the same physical host that the
IP address lives on. The Linux kernel may force that
application to take a shortcut to the local loopback
interface, instead of the interface the address
is really bound to. Under those circumstances, an
application may, somewhat unexpectedly, continue
to use connections for some time even after the
IP address is deconfigured. Set this parameter in
order to immediately disable said shortcut when the
IP address goes away.
Operations‘ defaults (advisory minimum):
start timeout=20s
stop timeout=20s
status timeout=20s interval=10s
monitor timeout=20s interval=10s
根据这个manual，我们添加IP Address
crm configure primitive ClusterIP ocf:heartbeat:IPaddr2 params ip=192.168.100.100 cidr_netmask=24 op monitor interval=30s

如果pacemaker01挂掉，则IP会到另外一台机器上，如果pacemaker01重启，是否IP会回来呢？
我们其实不想让他回来，于是设置下面的值，使得每次移动有成本
crm configure rsc_defaults resource-stickiness=100
我们来看/usr/lib/ocf/resource.d/heartbeat/apache
会发现apache_start会调用ocf_run $HTTPD $HTTPDOPTS $OPTIONS -f $CONFIGFILE
crm ra info ocf:heartbeat:apache
首先每个Node上都要安装apache2
apt-get install apache2 wget
每个机器上的网站内容不同，从而可以区分哪个网站
root@pacemaker01:~# vim /var/www/html/index.html

我们想让IP地址和apache的在同一个机器，才有意义
crm configure colocation website-with-ip INFINITY: WebSite ClusterIP
当cluster有变化重新配置的时候，先变IP，再变apache
