安装centos
centos7---vs
centos6---RS1、RS2
centos6---client
最小化安装centos,配置yum源；
cd /etc/yum.repos.d/
rm-rf *
vi base.repo
[base]
baseurl=file:///mnt
gpgcheck=0
#yum repolist
#yum makecache
#yum install vim
#yum install autofs
chkconfig autofs on
service autofs start
#vim base.repo
[base]
baseurl=file:///misc/cd
gpgcheck=0
设置ip地址，设置为静态ip；
使用VMware 仅主机和自定义模式（仅主机）
1、vs外网网卡设置为自定义模式；ip;192.168.183.151
vs内网网卡设置为仅主机模式；ip：192.168.226.151
2、RS1；仅主机模式，ip;192.168.226.140
RS2；仅主机模式，ip;192.168.226.141
3、client;自定义模式；ip;192.168.183.130
关闭防火墙及SElinux设置；
centos6;
#chkconfig iptables off
#chkconfig list iptables
#vim /etc/selinux/conf
#setenforce 0
#getenforce
centos7;
systemctl enable firewalld
systemctl stop firewalld
#vim /etc/selinux/conf
#setenforce 0
#getenforce
1、VS（centos7）安装ipvsadm；
设置VS服务模式；
设置VS的算法；
开启ipv4转发功能；
2、RS（centos6）安装httpd;
设置简单的网页；
将RS网关指向VS（192.168.226.151）；
3、client客户端访问vs端网页；
1、VS (centos 7)上安装ipvsadm，设置/etc/sysctl.conf配置文件、设置VS服务模式及算法;
#yum install ipvsadm
#Vim /etc/sysctl.conf
Net.ipv4.ip_forward=1
#ipvsadm -A -t 192.168.183.151:80 -s rr---模式
#ipvsadm -a -t 192.168.183.151:80 -r 192.168.226.140 -m ---算法
#ipvsadm -a -t 192.168.183.151:80 -r 192.168.226.141 -m
2、RS服务器将网关指向VS服务器，安装httpd并启用；
RS1;
# vim /etc/sysconfig/network-scripts
DEVICE=eth0
IPADDR=192.168.226.140
PREFIX=24
GATEWAY=192.168.226.151
RS2;
# vim /etc/sysconfig/network-scripts
DEVICE=eth0
IPADDR=192.168.226.141
PREFIX=24
GATWAY=192.168.226.151
#yum install httpd
#service httpd start
#chkconfig httpd on
创建简单的网页；
echo RS1 SERVER >/var/www/html/index.html
echo RS2 SERVER >/var/www/html/index.html
3、client客户端访问网页,检测是否成功；
#curl 192.168.183.151
#if i in {1..10};do curl 192.168.183.151;done
[root@client ~]#for i in {1..10};do curl 192.168.183.151;sleep 1;done
RS1 SERVICE
RS2 SERVICE
RS1 SERVICE
RS2 SERVICE
RS1 SERVICE
RS2 SERVICE
RS1 SERVICE
RS2 SERVICE
RS1 SERVICE
RS2 SERVICE
4、在vs上查看连接状态；
#Ipvsadm -Ln
[root@VS1 ~]# ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 192.168.183.151:80 rr
-> 192.168.226.140:80 Masq 1 0 8
-> 192.168.226.141:80 Masq 1 0 8
5、测试性能；
[root@client ~]#ab -c 100 -n 10000 http://192.168.183.151/

6、查看谁在访问；
Cat /var/log/httpd/access_log
7、查看谁访问的数量；
[root@RS1 network-scripts]#cut -d" " -f1 /var/log/httpd/access_log |sort - nr|uniq -c|sort -n
1 192.168.226.140
3 192.168.226.151
10 ::1
102 192.168.183.151
10328 192.168.183.130
8、查看每秒钟的访问数据平均速度；
[root@VS1 ~]# ipvsadm -Ln --rate
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port CPS InPPS OutPPS InBPS OutBPS
-> RemoteAddress:Port
TCP 192.168.183.151:80 1 5 5 447 545

-> 192.168.226.141:80 0 3 2 224 273
9、更改vs算法，更改RS权数；
Ipvsadm -E -t 192.168.183.151:80 -s wrr
Ipvsadm -e -t 192.168.183.151:80 -r 192.168.226.141 -m -w 3
再次访问时会有变化；
[root@client ~]#for i in {1..100};do curl 192.168.183.151;sleep 1;done
RS2 SERVICE
RS1 SERVICE
RS2 SERVICE
RS2 SERVICE

删除网卡模块；
/etc/udev/rules.d/70-persistent-ipoib.rules
- 卸载模块
- Rmmod e1000
- Modprobe e1000
添加ip地址
ip a add 192.168.226.151/24 dev eth0
