0总结
1知道了lvs能实现的功能挺强大。
2熟悉练习一下dpdk的环境搭建设置网卡支持多队列设置巨页dpdk接管网卡。
3dpvs是基于dpdk上的一个产物了解一下未涉及相关业务并未深入。
1lvs进行练习。
参考 LVS的介绍与使用-CSDN博客
1.1 首先安装nginx并启动 默认端口是80有多个网卡两个ip都能访问到。
sudo apt-get install nginx
netstat -anop|grep nginx
sudo systemctl restart nginx
ps afx|grep nginx
netstat -anop|grep nginx
curl 192.168.40.137:80
ifconfig
curl 192.168.40.139:801.2 安装lvs并进行测试
#这里简单配置 测试 具体根据实际场景
rootubuntu:/home/ubuntu/dpvs_test/dpvs-1.9.4/bin# apt-get install ipvsadm
rootubuntu:/home/ubuntu/dpvs_test/dpvs-1.9.4/bin# sudo modprobe ip_vsifconfig ens33:250 192.168.40.222/24 #临时设置 ip 作为虚拟ip
ifconfig
sudo ipvsadm -A -t 192.168.40.222:80 -s rr #配置虚拟ip 设置轮询
ipvsadm -L -n #查看配置
sudo ipvsadm -a -t 192.168.40.222:80 -r 192.168.40.139:80 #配置虚拟ip对应的两个真实ip
ipvsadm -L -n
sudo ipvsadm -a -t 192.168.40.222:80 -r 192.168.40.137:80
ipvsadm -L -n
ipvsadm -C #清除配置这里配置完成后使用curl或者直接在浏览器上访问这个虚拟ip 192.168.40.222:80 都能正常访问到nginx实际上后台是按照设置的负载均衡的策略依次访问后台真实的服务器。
1.3 补充
简单练习了解lvs真实场景根据业务虚拟ip提供对外访问的功能以及真实ip不提供设置以及配合keepalive实现能探测到服务的正常等都待了解。

2.1虚拟机环境,新增网卡配置多队列网卡。
dpdk要接管一个网卡这里使用桥接新增一个网卡设置支持多队列。
2.2.1 问题1新增的桥接模式的网卡要配置好ip配置静态ip(动态dhcp一直不成功)。
设置桥接模式然后dhcp进行获取ip发现一直不成功只能设置静态ip了。
这里还需要再vmware上设置 编辑—》虚拟网络编辑器中设置桥接模式桥接到真正连接网络的网卡上。 这里我用的wifi填的对应网卡。
