LVS 集群配置

用yum安装(先检查下yum是否可用,如果可用,就用yum安装)

#yum install ipvsadm piranha


修改LVS配置

#cd /etc/sysconfig/ha/

先对lvs默认配置文件进行备份,再创建新的配置文件

#mv lvs.cf lvs.cf.back

#vi lvs.cf   ####内容如下


serial_no = 39

primary = 10.5.20.12

service = lvs

backup_active = 1

backup = 10.5.20.13

heartbeat = 1

heartbeat_port = 539

keepalive = 3

deadtime = 9

network = direct

debug_level = NONE

monitor_links = 0

syncdaemon = 0

virtual XP {

     active = 1

     address = 10.5.20.14 bond0:0

     vip_nmask = 255.255.255.0

     port = 80

     send = "GET / HTTP/1.0\r\n\r\n"

     expect = "HTTP"

     use_regex = 0

     load_monitor = none

     scheduler = wlc

     protocol = tcp

     timeout = 5

     reentry = 5

     quiesce_server = 0

     server xp1 {

         address = 10.5.20.12

         active = 1

         weight = 1

     }

     server xp2 {

         address = 10.5.20.13

         active = 1

         weight = 1

     }

}


在两台物理机上分别启动心跳服务:
#  service pulse start
Starting pulse:                                            [  OK  ]
这时,能在主物理机10.5.20.12上看到负载均衡网卡已启动,
而10.5.20.13上是没有这个网卡的:
# ifconfig

          UP BROADCAST RUNNING MASTER MULTICAST  MTU:1500  Metric:1

当主物理机的服务关闭时,在10.5.20.13上看到网卡已启动:
# ifconfig

          inet addr:10.5.20.13  Bcast:10.5.23.255  Mask:255.255.252.0

查看虚拟服务器状态:
# ipvsadm -ln

IP Virtual Server version 1.2.1 (size=4096)

Prot LocalAddress:Port Scheduler Flags

  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn

TCP  10.5.20.14:80 wlc


将服务设成开机自启动:
# chkconfig --level 345 pulse on
