一、配置的网络拓扑结构图
二、配置lvs服务器
- 配置虚拟网卡地址（VIP地址）
[[email protected] ~]# ifconfig eno16777728:0 192.168.200.253 netmask 255.255.255.0
#查看配置结果
[[email protected] ~]# ifconfig eno16777728:0
eno16777728:0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.200.253 netmask 255.255.255.0 broadcast 192.168.200.255
ether 00:0c:29:f0:42:97 txqueuelen 1000 (Ethernet)
- 安装ipvsadm软件包实现lvs轮询
[[email protected] ~]# yum -y install ipvsadm #查看安装结果 [[email protected] ~]# rpm -qa ipvsadm ipvsadm-1.27-7.el7.x86_64
- 配置轮询规则
[[email protected] ~]# ipvsadm -A -t 192.168.200.253:80 -s rr [[email protected] ~]# ipvsadm -a -t 192.168.200.254:80 -r 192.168.200.112:80 -g -w 1 [[email protected] ~]# ipvsadm -a -t 192.168.200.253:80 -r 192.168.200.113:80 -g -w 1
三、配置Apache节点服务器（两台服务器配置相同）
- 配置虚拟网卡IP地址（VIP地址）
[[email protected] ~]# ifconfig lo:0 192.168.200.253 netmask 255.255.255.255
- 添加路由规则
[[email protected] ~]# route add -host 192.168.200.253 dev lo:0 #将访问VIP的数据限制在本地以避免通信紊乱。
- 调整/proc响应参数
[[email protected] ~]# 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.default.arp_announce = 2 net.ipv4.conf.lo.arp_ignore = 1 net.ipv4.conf.lo.arp_announce = 2 #启用参数 [[email protected] ~]# 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
- 安装Apache开启服务
[[email protected] ~]# yum -y install httpd #开启httpd服务 [[email protected] ~]# systemctl start httpd
四、测试
- 所有机器关闭防火墙，安全规则
[[email protected] ~]# systemctl stop firewalld [[email protected] ~]# setenforce 0 [[email protected] ~]# iptables -F
- 准备测试页
[[email protected] ~]# echo "111111111" > /var/www/html/index.html
- 测试
