Abstract： With the development ofcomputer and network technology，cluster systems have gradualy replaced traditional mainframes duetotheiradvantagesofscalabilityandhighcost-effectiveness，fiding widespreadapplicationacrossvarious fields. However，nodeuestwokissuesoudensiksiacssalleadtosicedsptios，makingthelabilityofster systems critical.RemoteProcedureCall（RPC），astheprimarycommunicationmethodbetweenclustersystemnodes，ishighly susceptibletseotd This paper designsand implements a multi-servicehotstandbysystem basedonthe Linux system，supporting both TCPand UDP services.Itprovidesahotstandbysolutionbasedoservice itselfforRPC，significantlyenhancing thereliabilityofclustersystems.
