LVS-DR负载均衡-02
LB及其RS配置3.1 负载均衡器配置配置
停止路由转发功能
# sysctl -wnet.ipv4.ip_forward=0
net.ipv4.ip_forward = 0
# sysctl -wnet.ipv4.conf.all.send_redirects=1
net.ipv4.conf.all.send_redirects = 1
# sysctl -wnet.ipv4.conf.default.send_redirects=1
net.ipv4.conf.default.send_redirects = 1
通过eth0绑定
# sysctl -wnet.ipv4.conf.eth0.send_redirects=1
net.ipv4.conf.eth0.send_redirects = 1
设置虚拟IP地址
# ifconfig eth0:0192.168.28.111netmask255.255.255.0
启用eth0:0
# ifconfigeth0:0up
清除ipvs规则表
# ipvsadm-C
查看集群分布
# ipvsadm-L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
为避免ARP解析 增加主机路由
# /sbin/route add -host192.168.28.111deveth0:0
# route-n

# ipvsadm-A-t192.168.28.111:80-srr
在LB MASTER中增加真实服务器
# ipvsadm-a-t192.168.28.111:80 -r 192.168.28.134 -g -w 1
# ipvsadm-a-t192.168.28.111:80 -r 192.168.28.135 -g -w 2

注：Backup LB中安装配置和MASTER一致
3.2 RServer 应用真实服务器配置
# sysctl -wnet.ipv4.ip_forward=0
忽略arp设置
# sysctl -wnet.ipv4.conf.lo.arp_ignore=1
设置Arp宣告值
# sysctl -wnet.ipv4.conf.lo.arp_announce=2
net.ipv4.conf.lo.arp_announce = 2
# sysctl -w net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_ignore = 1
# sysctl -w net.ipv4.conf.all.arp_announce=2
net.ipv4.conf.all.arp_announce = 2
配置RS02中VIP地址
# /sbin/ifconfig lo:0192.168.28.111netmask 255.255.255.255broadcast 192.168.28.111 up
查看路由表

0.0.0.0 192.168.28.2 0.0.0.0 UG 0 0 0 eth0
增加主机虚拟IP
# /sbin/routeadd-host192.168.28.111 devlo:0
再次查看路由表
