Linux之Bash_Script_Program_002

Ugly Bash 脚本一枚，用于配置LVS的DR模型(VIP/RIP/DIP同网段)。

Zero价值，Just 为了实验的时候少敲键盘 :)。

1.配置RealServer

#!/bin/bash
#
#Configure real server

VIP="192.168.1.200"

#config arp stuff
echo -e "E[1;36mStart configure ARP E[0m"
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
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/ip_forward
sleep 1
echo -e "E[1;36mDone. E[0m"

#config VIP
echo -e "E[1;36mStart configure VIP. E[0m"
ifconfig lo:0 down > /dev/null 2>&1
route del -host $VIP > /dev/null 2>&1
ifconfig lo:0 $VIP netmask 255.255.255.255 broadcast $VIP up
route add -host $VIP dev lo:0
sleep 1
echo -e "E[1;36mDone. E[0m"

#stop iptables
echo -e "E[1;36mStop iptables.E[0m"
service iptables stop
sleep 1
echo -e "E[1;36mDone.E[0m"

#start httpd
echo -e "E[1;36mStart httpd.E[0m"
service httpd stop > /dev/null 2>&1
service httpd start > /dev/null 2>&1
sleep 1
echo -e "E[1;36mDone.E[0m"

2.配置Director

#!/bin/bash
#
#Configure Director

VIP="192.168.1.200"
RIPArray=("192.168.1.201" "192.168.1.202")
PORT=80
IFACE="eth0:0"

ifconfig $IFACE down > /dev/null 2>&1
route del -host $VIP > /dev/null 2>&1
service iptables stop > /dev/null 2>&1

ipconfig $IFACE $VIP netmask 255.255.255.255 broadcast $VIP up
route add -host $VIP dev $IFACE

echo -e "E[1;36mConfigure DirectorE[0m"
ipvsadm -A -t $VIP:$PORT -s rr
for i in `seq 0 $((${#RIPArray[*]}-1))`;do
        [ -n ${RIPArray[$i]} ] && ipvsadm -a -t $VIP:$PORT -r ${RIPArray[$i]}:$PORT -g
        sleep 1
done
echo 1 > /proc/sys/net/ipv4/ip_forward
echo -e "E[1;36mDone.E[0m"
