在master上安装ipvsadm
[root@master ~]# yum install -y ipvsadm #配置好本地YUM源即可 启动ipvsadm [root@master ~]# /etc/init.d/ipvsadm start ipvsadm: Clearing the current IPVS table: [ OK ] ipvsadm: Applying IPVS configuration: [ OK ]
修sysctl.conf文件，实现路由转发
[root@master ~]# vim /etc/sysctl.conf .......... net.ipv4.ip_forward = 1 .......... 使立即生效 [root@master ~]# sysctl -p net.ipv4.ip_forward = 1 ........
使用ipvsadm添加规则
[root@master ~]# ipvsadm -A -t 192.168.30.130:80 -s rr 参数说明 -A 添加 -t 表示 TCP 的服务 VIP：PORT -s 指定调度算法 rr 表示 round-robin 轮循 [root@master ~]# ipvsadm -a -t 192.168.30.130:80 -r 192.168.17.131 -m [root@master ~]# ipvsadm -a -t 192.168.30.130:80 -r 192.168.17.132 -m 保存规则 [root@master ~]# /etc/init.d/ipvsadm save 查看规则 [root@master ~]# service ipvsadm status IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 192.168.30.130:80 rr -> 192.168.17.131:80 Masq 1 0 0 -> 192.168.17.132:80 Masq 1 0 0 [root@master ~]# ipvsadm -L -n IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 192.168.30.130:80 rr -> 192.168.17.131:80 Masq 1 0 0 -> 192.168.17.132:80 Masq 1 0 0
在node-1和node-2上
修改网关，创建测试页面并启动httpd服务
node-1和node-2上，IP设为192.168.17.131和192.168.17.132，GATEWAY设置为192.168.17.130。 安装httpd服务并创建测试页 [root@node-1 ~]# yum install -y httpd [root@node-1 ~]# echo "<h1>This is the node-1 Web-Server:192.168.17.131</h1>" > /var/www/html/index.html [root@node-2 ~]# echo "<h1>This is the node-2 Web-Server:192.168.17.132</h1>" > /var/www/html/index.html [root@node-1 ~]# service httpd restart Stopping httpd: [FAILED] Starting httpd: [ OK ]
测试
在linux终端
[root@master ~]# elinks 192.168.30.130:80 --dump This is the node-2 Web-Server:192.168.17.132 [root@master ~]# elinks 192.168.30.130:80 --dump This is the node-1 Web-Server:192.168.17.131 [root@master ~]# elinks 192.168.30.130:80 --dump This is the node-2 Web-Server:192.168.17.132 [root@master ~]# elinks 192.168.30.130:80 --dump This is the node-1 Web-Server:192.168.17.131
