lvs-net之单主机基于端口调度
实验环境：centos 7实验程序：httpd、ipvsadm
实验目的：在单台主机上用lvs做httpd基于端口的调度
IP端口主页

10.1.12.1381This is www2
10.1.12.1382This is www3
一、安装httpd并配置三个虚拟主机
# vi vhost.conf

# yum install -y ipvsadm

# ipvsadm -A -t 10.1.12.13:80 -s rr
# ipvsadm -a -t 10.1.12.13:80 -r 10.1.12.13:80 -m
# ipvsadm -a -t 10.1.12.13:80 -r 10.1.12.13:81 -m
# ipvsadm -a -t 10.1.12.13:80 -r 10.1.12.13:82 -m
# ipvsadm -L -n

三、测试
启动http服务并查看端口监听状态，在别的虚拟主机上使用curl命令测试，是否为三个主页文件轮询调度。在浏览器上测试一般会有缓存，所以还是别踩坑了
