系统 centos6.4-x86_64
前提各节点服务器 1构建第三方源配置完毕;2搭建好rsync服务。
(第三方源 http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/CentOS_CentOS-6/x86_64/) 安装基本软件（各节点服务器）

yum install -y vim git make automake gcc gcc-c++ glibc gd gd-devel glib-devel glibc-headers wget curl tar nc libcurl-devel openssl-devel zlib-devel zlib patch readline readline-devel libffi-devel curl-devel zip rsync ruby rubygems ruby-devel  htop mlocate python-dateutil redhat-rpm-config ntp

修改hosts文件，添加虚拟IP解析

vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.101      vm01-centos
10.0.0.102      vm02-centos
10.0.0.103      vm03-centos

yum install -y pacemaker cman ccs corosync pssh crmsh

添加开机启动

chkconfig pacemaker on

corosync-keygen

Set permissions on the key: (Do first server)

chown root:root /etc/corosync/authkeychmod 400 /etc/corosync/authkey

拷贝至其他节点

rsync –avh /etc/corosync/authkey root@10.0.0.101:/etc/corosync/authkeyrsync –avh /etc/corosync/authkey root@10.0.0.103:/etc/corosync/authkey
