2、VS是運彳T在Linux平臺上的一款開源軟件，主要功能是實現(xiàn) Linux平臺的負載均衡。 這款軟件在業(yè)界有著很高的知名度，同時在國互聯(lián)網(wǎng)公司有著很高的使用率，適合用于構建大型系統(tǒng)的負載均衡平臺。Keepalived是運行在LVS上面的雙機管理軟件，LVS配合Keepalived使用可以構建熱備雙機結構，實現(xiàn)主備機的切換。通過本文檔指導，可以架設一套LVS+keepalived結構的負載均衡雙機熱備系統(tǒng)。第二章軟件環(huán)境軟件版本centos6.6LVS1.26keepalived1.2.7第三章系統(tǒng)基本配置LVS、Keepalived依賴庫安裝LVS、Keepalived安裝需要一些軟件包的支持，
