一、构建LVS-DR集群
1、主机规划
Node01：PC
Node02：LVS文章来源：https://www.toymoban.com/news/detail-631222.html
Node03、Node04：Webserver文章来源地址https://www.toymoban.com/news/detail-631222.html
2、部署环境
2.1 在Node02上配置
2.1.1 安装ipvsadm管理软件按
[root@localhost ~]# yum install -y ipvsadm2.1.2 配置VIP
[root@localhost ~]# ifconfig ens33:200 192.168.100.200 netmask 255.255.255.255
[root@localhost ~]# ip ad
ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
inet 192.168.100.200/32 brd 192.168.100.255 scope global secondary ens33:200
valid_lft forever preferred_lft forever
2.2 在Node03上配置
2.2.1 安装Apache服务
[root@localhost ~]# yum install -y httpd2.2.2 编辑默认主页
[root@localhost ~]# echo "Web test page, ip is `hostname -I`." > /var/www/html/index.html
[root@localhost ~]# systemctl start httpd.service2.3 在Node04配置
2.3.1 安装Apache服务
[root@localhost ~]# yum install -y httpd2.3.2 编辑默认主页
[root@localhost ~]# echo "Web test page, ip is `hostname -I`." > /var/www/html/index.html
[root@localhost ~]# systemctl start httpd.service2.4 在Node01上测试
[root@localhost ~]# curl 192.168.100.5
Web test page, ip is 192.168.100.5 .
[root@localhost ~]# curl 192.168.100.6
Web test page, ip is 192.168.100.6 .3、绑定VIP
3.1 在Node03上配置
[root@localhost ~]# ifconfig lo:200 192.168.100.200 netmask 255.255.255.255 up
[root@localhost ~]# route add -host 192.168.100.200 dev lo3.2 在Node04行配置
[root@localhost ~]# ifconfig lo:200 192.168.100.200 netmask 255.255.255.255 up
[root@localhost ~]# route add -host 192.168.100.200 dev lo4、ARP抑制
4.1 在Node03上配置
[root@localhost ~]# echo "1" > /proc/sys/net/ipv4/conf/lo/arp_ignore
[root@localhost ~]# echo "2" > /proc/sys/net/ipv4/conf/lo/arp_announce
[root@localhost ~]# echo "1" > /proc/sys/net/ipv4/conf/ens33/arp_ignore
[root@localhost ~]# echo "2" > /proc/sys/net/ipv4/conf/ens33/arp_announce4.2 在Node04行配置
[root@localhost ~]# echo "1" > /proc/sys/net/ipv4/conf/lo/arp_ignore
[root@localhost ~]# echo "2" > /proc/sys/net/ipv4/conf/lo/arp_announce
[root@localhost ~]# echo "1" > /proc/sys/net/ipv4/conf/ens33/arp_ignore
[root@localhost ~]# echo "2" > /proc/sys/net/ipv4/conf/ens33/arp_announce5、在LVS（Node02）上添加RS
[root@localhost ~]# ipvsadm -A -t 192.168.100.200:80 -s rr
[root@localhost ~]# ipvsadm -a -t 192.168.100.200:80 -r 192.168.100.5:80 -g
[root@localhost ~]# ipvsadm -a -t 192.168.100.200:80 -r 192.168.100.6:80 -g6、在PC（Node01）上进行测试
[root@localhost ~]# for ((i=1;i<=6;i++)); do curl 192.168.100.200; done
Web test page, ip is 192.168.100.6 .
Web test page, ip is 192.168.100.5 .
Web test page, ip is 192.168.100.6 .
Web test page, ip is 192.168.100.5 .
Web test page, ip is 192.168.100.6 .
Web test page, ip is 192.168.100.5 .二、配置nginx负载均衡
1、部署环境
1.1 在Node03上配置
[root@localhost ~]# yum install -y httpd
[root@localhost ~]# echo "Web test page, ip is `hostname -I`." > /var/www/html/index.html1.2 在Node04上配置
[root@localhost ~]# yum install -y httpd
[root@localhost ~]# echo "Web test page, ip is `hostname -I`." > /var/www/html/index.html2、Node02 配置虚拟主机
2.1 编辑配置文件
[root@localhost ~]# cd /etc/nginx/conf.d/
[root@localhost conf.d]# vim vhost.conf
server{
listen 80;
server_name www1.openlab.cn;
location / {
proxy_pass http://192.168.100.5;
}
}
server{
listen 80;
server_name www2.openlab.cn;
location / {
proxy_pass http://192.168.100.6;
}
}[root@localhost conf.d]# vim lb.conf
upstream www_pools {
server 192.168.100.5:80 weight=1;
server 192.168.100.6:80 weight=2;
}
server {
listen 80:
server_name www.yunjisun.com;
location / {
proxy_pass http://www_server_pools;
}
}2.2 启动nginx
[root@localhost ~]# systemctl start nginx3、PC端（Node01）测试
[root@localhost ~]# for ((i=1;i<=9;i++)); do curl http://www.yunjisuan.com; done到了这里，关于基于 CentOS 7 构建 LVS-DR 集群 及 配置nginx负载均衡的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
