cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0:0
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=static DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=eth0:0 UUID=b6790a67-bcb1-4b5f-87f8-8355ef4ebea0 DEVICE=eth0:0 ONBOOT=yes IPADDR=192.168.0.108 NETMASK=255.255.255.0
systemctl restart network
2.安装ipvsadm并配置
yum install -y ipvsadm
ipvsadm -A -t 192.168.0.108 -s rr
ipvsadm -a -t 192.168.0.108:80 -r 192.168.0.133 -g
ipvsadm -a -t 192.168.0.108:80 -r 192.168.0.134 -g
[root@localhost ~]# ipvsadm -ln

#防火墙设置
firewall-cmd --permanent --add-port=80/tcp
forewall-cmd --reload
3、两台apache配置
yum install -y httpd
systemctl enable httpd
systemctl start httpd
cp /etc/sysconfig/network-scripts/ifcfg-lo /etc/sysconfig/network-scripts/ifcfg-lo:1
vi /etc/sysconfig/network-scripts/ifcfg-lo:1
DEVICE=lo:1 IPADDR=192.168.0.108 NETMASK=255.255.255.255 # If you're having problems with gated making 127.0.0.0/8 a martian, # you can change this to something else (255.255.255.255, for example) ONBOOT=yes NAME=loopback ~
systemctl restart network
firewall-cmd --permanent --add-port=80/tcp
#关闭VIP ARP响应
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
服务器添加首页
echo abctest192.168.0.134 >/var/www/html/index.html
echo edf is test192.168.0.133 >/var/www/html/index.html
4.测试
[root@lvs ~]# curl http://192.168.0.108
edf is test192.168.0.133
[root@lvs ~]# curl http://192.168.0.108
abctest192.168.0.134
[root@lvs ~]# curl http://192.168.0.108
edf is test192.168.0.133
[root@lvs ~]# curl http://192.168.0.108
edf is test192.168.0.133
5.脚本实现
lvs管理器上的脚本
#!/bin/bash #lvs管理器配置，lvs之DR模式 # vim /usr/local/sbin/lvs_nat.sh echo 1 > /proc/sys/net/ipv4/ip_forward ipv=/sbin/ipvsadm vip=192.168.0.108 rs1=192.168.0.133 rs2=192.168.0.34 #添加vip网卡之eth0:0 ifconfig eth0:0 down ifconfig eth0:0 $vip broadcast $vip netmask 255.255.255.255 up route add -host $vip dev eth0:0 ipvsadm -C ipvsadm -A -t 192.168.0.108 -s rr ipvsadm -a -t 192.168.0.108:80 -r 192.168.0.133 -g ipvsadm -a -t 192.168.0.108:80 -r 192.168.0.134 -g #关闭VIP ARP响应 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
两台apache上的配置脚本
#!/bin/bash # vim /usr/local/sbin/lvs_dr_rs.sh vip=192.168.0.108 #添加lo:1 ifconfig lo:1 $vip broadcast $vip netmask 255.255.255.255 up route add -host $vip lo:1 #关闭VIP ARP响应 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
