This article explains load balancing fundamentals, compares hardware appliances with the Linux Virtual Server (LVS) solution, details NAT, DR, and TUN modes, and provides step‑by‑step ipvsadm commands, Keepalived high‑availability configuration, kernel tuning, and troubleshooting for production environments.
This article explains the concept of IPVS (IP Virtual Server) as a layer‑4 load balancer, compares ipvs with iptables, details LVS scheduling algorithms, and provides step‑by‑step commands for configuring ipvsadm on both load‑balancer and real‑server nodes, including VIP setup and client testing.
This guide walks through planning a NAT architecture, preparing Linux hosts, configuring route and LVS servers, setting up real servers with httpd, creating an LVS NAT cluster, testing client access, and persisting ipvsadm rules for reliable load balancing.
This comprehensive guide explains Linux Virtual Server (LVS) fundamentals, its general architecture, various load‑balancing modes (NAT, DR, TUN, FULL‑NAT), scheduling algorithms, persistent‑connection options, and provides step‑by‑step ipvsadm commands and scripts for deploying and managing LVS clusters on CentOS 7.
This tutorial walks through planning the NAT architecture, preparing hosts, configuring Linux route, LVS, and rs servers, installing httpd, setting up ipvsadm load‑balancing rules, testing client access via gateway or direct router IP, and persisting the configuration for a reliable Linux LVS NAT solution.
This article introduces IPVS, the Linux kernel‑level load balancer, explains its scheduling algorithms, forwarding modes (DR, NAT, IP tunneling), and provides step‑by‑step commands to configure virtual services, real servers, and routing in a virtualized environment.
This tutorial explains how to use the ipvsadm command to create and manage LVS/NAT and LVS/DR load‑balancing clusters on Linux, covering command syntax, environment setup for director and real servers, ARP tuning, rule persistence, and extended exercises for HTTP, HTTPS, and MySQL traffic.
This article walks through a practical setup of LVS DR mode load balancing on four UCloud servers, covering network configuration, ARP tweaks, ipvsadm rules, VIP assignment, troubleshooting steps, and implementing high‑availability with Keepalived, complete with command examples and visual screenshots.
This article explains what an LVS cluster is, outlines its types (LB, HA, HP), details common LVS deployment modes (nat, dr, tun) and their features, describes scheduling algorithms, and provides practical ipvsadm commands and configuration examples for building and managing high‑availability Linux load‑balancing clusters.
This article explains common load‑balancing solutions, details Linux Virtual Server (LVS) architecture, types, scheduling algorithms, and provides practical ipvsadm command examples for configuring NAT, DR, TUN, and FULLNAT models in a Linux environment.
This guide explains the fundamentals of Linux Virtual Server (LVS), covering cluster concepts, types, scheduling algorithms, ipvsadm commands, and detailed configuration examples for NAT and DR models, culminating in a complete web‑server load‑balancing deployment with Discuz on CentOS.
