前端机的执行命令和启动,这里我们采用nginx做前端机:

# /etc/init.d/lvsdr
# nginx机子
# 在/etc/init.d下创建lvsdr，内容如下：
# 修改脚本权限：chmod +x /etc/init.d/lvsdr
# 启动real server：service lvsdr start
# 停止real server：service lvsdr stop
# 在/etc/init.d下创建lvsdr，内容如下：

########################

VIP=10.235.165.100 #虚拟ip，根据需求修改

. /etc/rc.d/init.d/functions
case $1 in
        start)
        echo "lo:0 port starting"
        # 为了相应lvs调度器转发过来的包,需在本地lo接口上绑定vip
        ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
        # 限制arp请求
        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
        ;;
        stop)
        echo "lo:0 port closing"
        ifconfig lo:0 down
        echo "0" > /proc/sys/net/ipv4/conf/lo/arp_ignore
        echo "0" > /proc/sys/net/ipv4/conf/lo/arp_announce
        echo "0" > /proc/sys/net/ipv4/conf/all/arp_ignore
        echo "0" > /proc/sys/net/ipv4/conf/all/arp_announce
        ;;
        *)
        echo "Usage: $0 {start ¦ stop}"
        exit 1
