The invention discloses an automatic deployment method and device for a credential cloud platform; the method comprises the following steps: S1, installing and deploying a server node, and configuring the server node; s2, automatically acquiring all servers in the cluster through a server node, and reading hardware information of the servers; s3, installing operating systems on the servers in batches through the server nodes, and performing the basic environment configuration and network division configuration according to the divided server roles; s4, deploying a basic environment and a service product of the credential cloud platform through the server node; s5, performing function and performance test on the deployment and configuration through the server node, and generating a detection report. The method supports multiple network architecture requirements, can adapt to each hardware combination architecture of the credential and the credential, greatly improves the deployment efficiency of the credential and credential cloud platform, avoids the problems of construction period delay and the like caused by different scenes, and meets the quick delivery requirement of the credential and credential cloud center.
