The present invention discloses a hypertext transfer protocol secure (HTTPS) service deployment method. The method comprises the following steps that a private key server is set, and a content distribution network (CDN) node downloads an encrypted private key and a decryption method from the private key server and stores the encrypted private key and the decryption method in a memory of the CDN node; when a client and a server shake hands, the server uses the private key to decrypt, and uses the decryption method in the memory to decrypt a secret key, so as to complete a handshake process; after the handshake process is completed, a plaintext private key is emptied immediately; after handshake succeeds, the client and the CDN node communicate through symmetrical secret keys; and the CDN node forwards a client request to a source station, and returns a feedback result of the source station to the client, so as to complete an access process. According to the method, the private key is not deployed in the CDN node, the encrypted private key is deployed in the private key server, the private key is encrypted and the encrypted private key and the corresponding decryption method are used as data to transmit and store, the client uses the data in the memory to access without being intervened by the private key server, so that the performance and reliability of the system are improved.
