Method, system and device for cross-network deployment of bastion host main-standby communication, and medium

The invention relates to the technical field of operation and maintenance auditing, in particular to a method, a system and equipment for cross-network deployment of main and standby communication of a bastion host and a medium. Firstly, initialization operation is carried out, and the state of a network card port is judged; secondly, initializing default parameters of a VRRP protocol according to the number of network card port states UP and the network card port states, and setting a communication mode of the VRRP protocol; and finally, building a high-availability cluster according to a set communication mode. The cross-network deployment communication of the cloud bastion host is realized, and the main-standby communication problem in a cloud network cross-network segment scene is solved; and when the mode is a unicast mode, the IP cross-network deployment can still complete VRRP communication, and a high availability solution of HA keepalive is realized. 本发明涉及运维审计技术领域，具体地说，涉及一种跨网部署堡垒机主备通信的方法、系统、设备及介质；首先进
