centos中lvs安装配置方法详解

一、lvs-NAT模式

网络配置：

复制代码

代码如下:

lvs-server eth0 ：Host-only adapter 192.168.56.101lvs-server eth1 ：Internal 192.168.0.1real-server-1 eth0：Internal 192.168.0.2real-server-2 eth0：Internal 192.168.0.3

lvs-server：1、安装ipvsadm软件

复制代码

代码如下:

yum -y install ipvsadm*echo 1 > /proc/sys/net/ipv4/ip_forward 路由器功能，ip转发ipvsadm -Cipvsadm -At 192.168.56.101:80 -s rr 轮叫模式ipvsadm -at 192.168.56.101:80 -r 192.168.0.2 -mipvsadm -at 192.168.56.101:80 -r 192.168.0.3 -mipvsadm -L -n

2、real-server-1：

复制代码

代码如下:

ifCONfig eth0 192.168.0.2 netmask 255.255.255.0route add default gw 192.168.0.1

3、real-server-2

复制代码

代码如下:

ifconfig eth0 192.168.0.3 netmask 255.255.255.0route add default gw 192.168.0.1route -n 查看路由表

二、lvs-ipturn

网络配置：

复制代码

代码如下:

lvs-server eth0：host-only adapter 192.168.56.101real-server-1 eth0：host-only adapter 192.168.56.102real-server-2 eth0：host-only adapter 192.168.56.103

lvs-server：配置虚拟ip即vip

复制代码

代码如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 uproute add -host 192.168.56.10 dev tunl0

ivsadm -Cipvsadm -At 192.168.56.10:80 -s rripvsadm -at 192.168.56.10:80 -r 192.168.56.102 -iipvsadm -at 192.168.56.10:80 -r 192.168.56.103 -iipvsadm -L -n

real-server-1：

复制代码

代码如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 uproute add -host 192.168.56.10 dev tunl0echo 1 > /proc/sys/net/ipv4/conf/tunl0/arp_ignoreecho 2 > /proc/sys/net/ipv4/conf/tunl0/arp_announceecho 1 > /proc/sys/net/ipv4/conf/all/arp_ignoreecho 2 > /proc/sys/net/ipv4/conf/all/arp_announce

real-server-2：

复制代码

代码如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 uproute add -host 192.168.56.10 dev tunl0echo 1 > /proc/sys/net/ipv4/conf/tunl0/arp_ignoreecho 2 > /proc/sys/net/ipv4/conf/tunl0/arp_announceecho 1 > /proc/sys/net/ipv4/conf/all/arp_ignoreecho 2 > /proc/sys/net/ipv4/conf/all/arp_announce

三、lvs-dr

网络配置：

复制代码

代码如下:

lvs-server eth0：host-only adapter 192.168.56.101

real-server-1 eth0：host-only adapter 192.168.56.102

real-server-2 eth0：host-only adapter 192.168.56.103

lvs-server：

ifconfig eth0:0 192.168.56.10 netmask 255.255.255.255

route add -host 192.168.56.10 dev eth0:0

ipvs:

复制代码

代码如下:

ipvsadm -C ipvsadm -At 192.168.56.10:80 -s rr ipvsadm -at 192.168.56.10:80 -r 192.168.56.102 -g ipvsadm -at 192.168.56.10:80 -r 192.168.56.103 -g ipvsadm -L -n

real-server-1： ifconfig lo:0 192.168.56.10 netmask 255.255.255.255 route add -host 192.168.56.10 dev lo:0 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

real-server-2： ifconfig lo:0 192.168.56.10 netmask 255.255.255.255 route add -host 192.168.56.10 dev lo:0 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
