Linux HA环境搭建，使用Heartbeat
2台机器，各有2个网卡192.168.0.1 node1
192.168.1.1 node1 心跳
192.168.0.2 node2
192.168.1.2 node2 心跳
安装
libnet-devel-1.1.5-1.el5.i386.rpm
libnet-1.1.5-1.el5.i386.rpm
heartbeat-2.1.3.tar
配置heartbeat（2台机器的3个配置文件内容一样）
# cp /usr/local/share/doc/heartbeat-2.1.3/ha.cf /usr/local/etc/ha.d/
# cp /usr/local/share/doc/heartbeat-2.1.3/haresources /usr/local/etc/ha.d/
# cp /usr/local/share/doc/heartbeat-2.1.3/authkeys /usr/local/etc/ha.d/
vi ha.cf :
logfile /var/log/ha-log
crm yes
bcast eth1
node node1 node2
keepalive 2
warntime 5
deadtime 20
initdead 120
vi authkeys :
auth 1
1 sha1 key-for-sha1-any-text-you-want
更改Authkeys文件的权限：
chmod 600 /etc/ha.d/authkeys
vi haresources :
node1 192.168.132.10 Filesystem::/dev/sdd1::/ha::ext3 ncserver.sh
ncserver.sh存放在/etc/init.d，为应用启动脚本。需支持start,stop参数
启动heartbeat
service heartbeat start
