1.编辑/etc/hosts文件
vi /etc/hosts
192.168.203.57 fca-vm-search-apache1.synnex.org 主server主机名
192.168.203.58 fca-vm-search-apache2.synnex.org 备用server主机名
2. 在主备servers都安装libnet
wget
tar -zxvf libnet.tar.gz -C /usr/local/src/
cd /usr/local/src/libnet
./configure
make
make install
3. 在主备servers都安装heartbeat
wget
tar -zxvf heartbeat-2.1.3.tar.gz -C /usr/local/src
cd /usr/local/src/heartbeat-2.1.3
./configure
groupadd haclient
useradd -g haclient hacluster
make
make install
heartbeat安装完成后，自动在/etc/rc.d/init.d/目录下生成启动脚本heartbeat，启动heartbeat可以使用命令:
/etc/rc.d/init.d/heartbeat start
4.在主备servers上，将heartbeat作为系统服务
chkconfig --add heartbeat
chkconfig heartbeat on 开机自动启动
cd /usr/local/src/heartbeat-2.1.3/doc/
cp {ha.cf,haresources,authkeys} /usr/local/etc/ha.d/
5. 编辑ha.cf文件
#vi ha.cf
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 30
warntime 10
initdead 120
udpport 694
ucast eth0 192.168.203.57 双机中对方节点的真实IP地址，非虚拟IP
auto_failback on 当主节点恢复时，是否切换回主节点，on 切换，off 不切换
node fca-vm-search-apache1.synnex.org 主节点uname -n
node fca-vm-search-apache2.synnex.org 备用节点uname -n
6.编辑authkeys文件 主备节点上这个文件必须是相同的
#vi authkeys
auth 1
1 crc
#chmod 600 authkeys
