這篇文章主要講解了“centos中lvs安裝和配置方法”，文中的講解內容簡(jiǎn)單清晰，易于學(xué)習與理解，下面請大家跟著(zhù)小編的思路慢慢深入，一起來(lái)研究和學(xué)習“centos中lvs安裝和配置方法”吧！

一、lvs-nat模式

網(wǎng)絡(luò )配置：

代碼如下:

lvs-server eth0 ：host-only adapter 192.168.56.101
lvs-server eth2 ：Internal 192.168.0.1
real-server-1 eth0：Internal 192.168.0.2
real-server-2 eth0：Internal 192.168.0.3

 
lvs-server：
1、安裝ipvsadm軟件

代碼如下:

yum -y install ipvsadm*
echo 1 > /proc/sys/net/ipv4/ip_forward 路由器功能，ip轉發(fā)
ipvsadm -C
ipvsadm -At 192.168.56.101:80 -s rr 輪叫模式
ipvsadm -at 192.168.56.101:80 -r 192.168.0.2 -m
ipvsadm -at 192.168.56.101:80 -r 192.168.0.3 -m
ipvsadm -L -n

2、real-server-1：

代碼如下:

ifconfig eth0 192.168.0.2 netmask 255.255.255.0
route add default gw 192.168.0.1

3、real-server-2

代碼如下:

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

 
二、lvs-ipturn

網(wǎng)絡(luò )配置：

代碼如下:

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：
配置虛擬ip即vip

代碼如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0</p> <p>ivsadm -C
ipvsadm -At 192.168.56.10:80 -s rr
ipvsadm -at 192.168.56.10:80 -r 192.168.56.102 -i
ipvsadm -at 192.168.56.10:80 -r 192.168.56.103 -i
ipvsadm -L -n

real-server-1：

代碼如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0
echo 1 > /proc/sys/net/ipv4/conf/tunl0/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/tunl0/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：

代碼如下:

ifconfig tunl0 192.168.56.10 netmask 255.255.255.255 up
route add -host 192.168.56.10 dev tunl0
echo 1 > /proc/sys/net/ipv4/conf/tunl0/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/tunl0/arp_announce
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
