LVS DR模式实验

实验环境：

192.168.200.111    LVS DR模式调度器

192.168.200.112    httpd服务器

192.168.200.113     NFS共享服务器

192.168.200.114     httpd服务器

111机器的配置

yum -y install ipvsadm

ifconfig ens32:0 192.168.200.254  netmask 255.255.255.0

 ipvsadm -A -t 192.168.200.254:80 -s rr

ipvsadm -a -t 192.168.200.254:80 -r 192.168.200.112:80 -g -w 1

ipvsadm -a -t 192.168.200.254:80 -r 192.168.200.114:80 -g -w 1

ipvsadm -Ln

112和114机器的配置

yum -y install httpd

echo "1111111"  > /var/www/html/index.html   （114 可以是33333）

systemctl start httpd

ifconfig lo:0 192.168.200.254 netmask 255.255.255.255

vim /etc/sysctl.conf

sysctl -p
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.default.arp_ignore = 1
net.ipv4.conf.default.arp_announce = 2
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2

 二共享存储

113机器配置

yum -y install rpcbind nfs-utils

vim /etc/exports

/opt/wwwroot 192.168.200.0/24(rw,no_root_squash,sync)

 mkdir /opt/wwwroot

systemctl start rpcbind  (建议先打开rpcbind）

systemctl start nfs

[root@localhost ~]# showmount -e
Export list for localhost.localdomain:
/opt/wwwroot 192.168.200.0/24

echo "choudidi"  >> /opt/wwwroot/index.html

112和114机器配置

showmount -e 192.168.200.113

mount 192.168.200.113:/opt/wwwroot /var/www/html/

cat /var/www/html/index.html
