Debian5.0 实现RAS双机 集群Heartbeat (一)
Debian5.0 双机实验手册弄了一天了终于搞定了，好了废话不多说尽情享受吧http://blog.运维网.com/editor/icons/etc_17.gif
一、概述：
系统：debian5.0
集群软件：Heartbeat
服务器Lb1(主)： IP:192.168.2.222
服务器Lb2（从）： IP:192.168.4.222
虚拟IP ：192.168.5.222
二、下载安装软件包和配置：
lb1/lb2:
1、需要以下软件包：aptitude install heartbeat
2、在lb1和lb2服务器上配置heartbeat，需要有以下三个文件:
authkeys、ha.cf、haresources，它们存在于/etc/ha.d/目录里。
3. 创建以上提到的三个文件：
lb1/lb2: 我们需要从/usr/share/doc/heartbeat目录下拷贝authkeys、ha.cf、haresources三个文件到/etc/ha.d/目录下面。
Lb1:/etc/ha.d# cp /usr/share/doc/heartbeat/authkeys/etc/ha.d/
Lb1:/etc/ha.d# cp /usr/share/doc/heartbeat/ ha.cf.gz/etc/ha.d/
Lb1:/etc/ha.d# cp /usr/share/doc/heartbeat/ haresources.gz/etc/ha.d/
Lb1:/etc/ha.d# gunzip ha.cf.gz
Lb1:/etc/ha.d# haresources.gz
Lb2:/etc/ha.d# cp /usr/share/doc/heartbeat/authkeys/etc/ha.d/
Lb2:/etc/ha.d# cp /usr/share/doc/heartbeat/ ha.cf.gz/etc/ha.d/
Lb2:/etc/ha.d# cp /usr/share/doc/heartbeat/ haresources.gz/etc/ha.d/
Lb2:/etc/ha.d# haresources.gz
Lb2:/etc/ha.d# gunzip ha.cf.gz
4、配置：
4.1、首先编辑authkeys文件:
lb1/lb2:
vi /etc/ha.d/authkeys
#1 crc
#2 sha1 HI!
3 md5 Hello!#这里选择md5加密 密码为Hello!
lb1/lb2:
chmod 600 /etc/ha.d/authkeys
lb1:
vi /etc/ha.d/ha.cf
#
# keepalive: how many seconds between heartbeats
#
keepalive 2
#
# deadtime: seconds-to-declare-host-dead
#
deadtime 10
# What UDP port to use for udp or ppp-udp communication?
#
logfile /var/log/ha-log
udpport 694
bcasteth0
mcast eth0 225.0.0.1 694 1 0
ucast eth0 192.168.4.222
# What interfaces to heartbeat over?
udp eth0
#
# Facility to use for syslog()/logger (alternative to log/debugfile)
#
logfacility local0
#
# Tell what machines are in the cluster
# node nodename ... -- must match uname -n
node lb1.example.com
node lb2.example.com
注意:
ucastIP指向为另外一台lb2服务器192.168.4.222 (lb2.example.com).
lb2:
vi /etc/ha.d/ha.cf
#
# keepalive: how many seconds between heartbeats
#
logfile /var/log/ha-log
keepalive 2
#
# deadtime: seconds-to-declare-host-dead
#
deadtime 10
#
# What UDP port to use for udp or ppp-udp communication?
#
udpport 694
bcasteth0
mcast eth0 225.0.0.1 694 1 0
ucast eth0 192.168.2.222
# What interfaces to heartbeat over?
udp eth0
#
# Facility to use for syslog()/logger (alternative to log/debugfile)
#
logfacility local0
#
# Tell what machines are in the cluster
# node nodename ... -- must match uname -n
node lb1.example.com
node lb2.example.com
lb1/lb2:
vi /etc/ha.d/haresources
lb1.example.com 192.168.5.222
lb1/lb2:
/etc/init.d/heartbeat start
如何检查是否开启。
Lb1:
发现多了eht0:0说明已经正常启动
ifconfig

lb2:
而lib2服务器没有显示虚拟IP
