5.realserver配置3.LVS调度机的OSPF配置

【最佳答案】a.添加启动服务脚本/etc/init.d/lvs_realserver请自行按需要修改脚本中SNS_VIP变量#!/bin/sh### BEGIN INIT INFO# Provides: lvs_realserver# Derealserver配置 1 a.添加启动服务脚本/etc/init.d/lvs_realserver请自行按需要修改脚本中SNS_VIP变量

总结到这里，LVS Cluster架构已部署完了，如果各位有其他更好的LVS扩展方式请留意或者联系我，互相交流 QQ:83766787 。另外以前做了一个LVS的管理平台，但是一直都做得不好，也希望有相关平台开发经验的能联系我，交流交流、

LVS调度机的OSPF配置 2 a.安装软路由软件quaggayum ?y install quagga
b.配置zerba.confvim /etc/quagga/zebra.conf
hostname lvs-route-1password xxxxxxenable password xxxxxxlog file /var/log/zebra.logservice password-encryption
c.配置ospfd.confvim /etc/quagga/ospfd.conf
#ospf的配置类似于上面三层设备，注意需要把vip声明出去(1.1.1.1)log file /var/log/ospf.loglog stdoutlog sysloginterface eth0ip ospf hello-interval 1ip ospf dead-interval 4router ospfospf router-id 192.168.0.1log-adjacency-changesauto-cost reference-bandwidth 1000network 1.1.1.1/32 area 0.0.0.0network 192.168.0.0/24 area 0.0.0.0
d.开启IP转发sed ?i ‘/net.ipv4.ip_forward/d’ /etc/sysctl.confecho "net.ipv4.ip_forward = 1" >> /etc/sysctl.confsysctl ?p
e.开启服务/etc/init.d/zebra start /etc/init.d/ospfd start chkconfig zebra on chkconfig ospfd on
三层设备OSPF配置 3#查找与三层交换与lvs调度相连的端口，在本文端口分别为 g1/0/2 g1/0/3 g1/0/6#把g1/0/2改为三层端口，并配上IPinterface GigabitEthernet1/0/2port link-mode routeip address 192.168.0.1 255.255.255.0#配置ospf的参数, timer hello是发送hello包的间隔,timer dead是存活的死亡时间。默认是10，40 。#hello包是ospf里面维持邻居关系的报文，这里配置是每秒发送一个，当到4秒还没有收到这个报文，就会认为这个邻居已经丢失，需要修改路由ospf timer hello 1ospf timer dead 4ospf dr-priority 100#如此类推，把g1/0/3 g1/0/6都配置上interface GigabitEthernet1/0/3port link-mode routeip address 192.168.3.1 255.255.255.0ospf timer hello 1ospf timer dead 4ospf dr-priority 99interface GigabitEthernet1/0/6port link-mode routeip address 192.168.2.1 255.255.255.0ospf timer hello 1ospf timer dead 4ospf dr-priority 98#配置ospfospf 1area 0.0.0.0network 192.168.0.0 0.0.0.255network 192.168.3.0 0.0.0.255network 192.168.2.0 0.0.0.255
硬件资源准备 4 三层设备：本文用的是h3c 5800三层交换机
LVS调度机三台： 192.168.0.2 192.168.2.2 192.168.3.2
Realserver三台:1.1.1.100 1.1.1.101 1.1.1.102
LVS keepalived配置 5 在此架构下，LVS只能配置成DR模式。如果要配置成NAT模式，我的想法是，需要参照上面的方式让LVS调度机与内网三层设备配置ospf，此方法未验证，有其他方案请告知。
a.修改配置文件 keepalived.conf ，在Cluster架构中，所有调度机用相同的配置文件vim /etc/keepalived/keepalived.conf
