安装共享储存服务

创建储存根目录
[root@centos03~]# mkdir /web
[root@centos03 ~]# echo “www.nfs.com” > /web/index.html
启动服务
[root@centos03 ~]# systemctl start nfs
[root@centos03 ~]# systemctl start rpcbind
[root@centos03 ~]# systemctl enable nfs
[root@centos03 ~]# systemctl enable rpcbind
网站链接共享

配置LVS的NAT模式
[root@centos04 ~]#vim /etc/sysctl.conf
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.default.send_redirects = 0
net.ipv4.conf.ens32.send_redirects = 0
修改网站参数运行
[root@centos01 ~]# vim /etc/sysctl.conf
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.default.arp_ignore = 1
net.ipv4.conf.defauil.arp_announce = 2
net.ipv4.conf.lo.arp_ignore = 1
net.ipv4.conf.lo.arp_announce = 2

指定LVS负载均衡ip地址和端口
[root@centos04 ~]# ipvsadm -A -t
[root@centos04 ~]# ipvsadm -a -t
