LVS单机搭建笔记

LVS服务配置：

1. node01:

ifconfig  eth0:8 192.168.150.100/24

2. node02~node03:

1)修改内核：
        echo 1  >  /proc/sys/net/ipv4/conf/eth0/arp_ignore 
        echo 1  >  /proc/sys/net/ipv4/conf/all/arp_ignore 
        echo 2  >  /proc/sys/net/ipv4/conf/eth0/arp_announce 
        echo 2  >  /proc/sys/net/ipv4/conf/all/arp_announce 
2）设置隐藏的vip：
        ifconfig  lo:3 192.168.150.100 netmask 255.255.255.255

3. RS中的服务-node02~node03:

yum install httpd -y
service httpd start
vi /var/www/html/index.html
    from 192.168.150.1x

4. 安装ipvsadm模块

yum install ipvsadm 

5. 配置虚拟主机与真实服务器信息：

ipvsadm -A  -t  192.168.150.100:80  -s rr
ipvsadm -a  -t 192.168.150.100:80  -r  192.168.150.12 -g -w 1
ipvsadm -a  -t 192.168.150.100:80  -r  192.168.150.13 -g -w 1
ipvsadm -ln    #查看lvs配置信息
ipvsadm -lnc    #查看偷窥记录本

6. 浏览器访问，轮训至12、13机器
