負載均衡服務器腳本配置
作者：佚名
文章摘要：負載均衡服務器的配置過程，首先了解各個設備的IP分配具體內容，之后是apache，resin的配置代碼展示。希望大家能從中學到配置方法和思路。
接觸負載均衡這個領域已經有一段時間了，但是對于linux下的負載均衡服務器的設置問題總是掌握的不得要領。那么現在，特意找來了一篇資料，跟大家一起分享。共同看看具體的配置過程是如何的。那么，具體的內容，我們一起來看文章吧。
兩臺resin 服務器和兩臺apache服務器､一臺負載均衡服務器,一共5臺server。
兩臺apache服務器ip地址：
apache1 ip:192.168.9.101
apache2 ip:192.168.9.110
兩臺resin 服務器ip地址：
resin1 ip:192.168.9.145
resin2 ip:192.168.9.146
一臺負載均衡服務器ip地址：
vip1:192.168.9.106 提供兩臺apache負載均衡的虛擬ip地址
vip2:192.168.9.150 提供兩臺resin負載均衡的虛擬ip地址
負載均衡服務器 ip地址192.168.9.109
apache1 lvs相關配置如下:
建一個shell腳本vi /usr/local/lvs/real.sh
- #!/bin/bash
- # set the Virtual IP Address
- /sbin/ifconfig lo:0 192.168.9.106 broadcast 192.168.9.106 netmask 255.255.255.255 up
- /sbin/route add -host 192.168.9.106 dev lo:0
- #off ARP
- echo "1" > /proc/sys/net/ipv4/conf/lo/arp_ignore
- echo "2" > /proc/sys/net/ipv4/conf/lo/arp_announce
- echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore
- echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce
- # run
- sysctl -p
- #end
保存退出#p#
將此腳本添加自啟動文件
- [root@web1 ~]# cat /etc/rc.local
- #!/bin/sh
- #
- # This script will be executed *after* all the other init scripts.
- # You can put your own initialization stuff in here if you don't
- # want to do the full Sys V style init stuff.
- /usr/local/lvs/real.sh
- touch /var/lock/subsys/local
apache2服務器lvs配置和apache1相同
resin1服務器lvs配置如下
建一個shell腳本 vi /usr/local/realserver/real.sh
- #!/bin/bash
- # set the Virtual IP Address
- /sbin/ifconfig lo:0 192.168.9.150 broadcast 192.168.9.150 netmask 255.255.255.255 up
- /sbin/route add -host 192.168.9.150 dev lo:0
- #off ARP
- echo "1" > /proc/sys/net/ipv4/conf/lo/arp_ignore
- echo "2" > /proc/sys/net/ipv4/conf/lo/arp_announce
- echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore
- echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce
- # run
- sysctl -p
- #end
#p#將此腳本添加自啟動文件
- [root@resin1 ~]# cat /etc/rc.local
- #!/bin/sh
- #
- # This script will be executed *after* all the other init scripts.
- # You can put your own initialization stuff in here if you don't
- # want to do the full Sys V style init stuff.
- /usr/local/realserver/real.sh
- touch /var/lock/subsys/local
resin2服務器lvs配置和resin1相同
