大数据学习笔记(十三) -- 搭建lvs DR模型

lvs服务器下 ， 在eth0网卡上在配置一个ip   /24 代表 netmask 为 255.255.255.0

所有基于内核的配置修改不能使用vi ，只能使用重定向

[[email protected] ~]# ifconfig eth0:8 192.168.46.100/24
[[email protected] ~]# echo "1" >/proc/sys/net/ipv4/ip_forward

两台 RS服务器下 更改接口访问权限  -- 安装 httpd --- 设置首页

[[email protected] ~]# echo 1 >/proc/sys/net/ipv4/conf/eth0/arp_ignore
[[email protected] ~]# echo 2 >/proc/sys/net/ipv4/conf/eth0/arp_announce 
[[email protected] ~]# echo 1 >/proc/sys/net/ipv4/conf/all/arp_ignore
[[email protected] ~]# echo 2 >/proc/sys/net/ipv4/conf/all/arp_announce
[[email protected] ~]# ifconfig lo:3 192.168.46.100 netmask 255.255.255.255

[[email protected] ~]# yum install httpd -y
[[email protected] ~]# cd /var/www/html/
[[email protected] html]# vi index.html     # 内容输入的是 from 192.168.46.23
[[email protected] html]# service httpd start

测试

安装ipvsadm

[[email protected] ~]# yum install ipvsadm -y

配置ipvsadm的负载模式，rr代表轮询

[[email protected] ~]# ipvsadm -A -t 192.168.46.100:80 -s rr

指定为哪些RS做负载

[[email protected] ~]# ipvsadm -a -t 192.168.46.100:80 -r 192.168.46.22 -g
[[email protected] ~]# ipvsadm -a -t 192.168.46.100:80 -r 192.168.46.23 -g
