s110, when a new server process is started, if the new server process detects that an old server process exists, sending a handover notification to the old server process.
Optionally, when the server process is stuck in the running process or the server process has a defect, a new server process needs to be started, so that the new server process replaces the old server process to run, and the server runs smoothly.
When the new server process is started, the existing old server process is detected to be running, the new server process sends a handover notification to the old server process, and after the old server process receives the handover notification sent by the new server process, the new server process carries out handover on related information and the new server process, so that the new server process can replace the old server process to process a connection request of a user, the stable running of a server is guaranteed, and the experience of the user is enhanced.
And S120, the new server process receives the monitoring socket sent by the old server process and connects the monitoring socket with the user.
And after receiving the handover notification sent by the new server process, the old server process sends the monitoring socket and the user connection to the new server. The listening socket is the server as an endpoint of the client connection request, it is created once, and exists throughout the server's lifecycle. The server processes the connection request of the user through the monitoring socket, and when the new server receives the monitoring socket sent by the old server, the new server processes the connection request of the user through the received monitoring socket, so that the user establishes connection with the server through the process of the new server. The old server process no longer processes the user's connection request.
Optionally, the step of receiving, by the new server process, the listening socket sent by the old server process to connect with the user includes: and the new server process receives the monitoring socket sent by the old server process through the transmission of the connection descriptor by the operating system.

The old server process sends the listening socket to the new server process through the transport connection descriptor of the operating system, so that the new server process can process the connection request of the user.
The user connection is connection information that the user has established a connection with the server. When the old server process sends the connection information of the user establishing connection with the server to the new server process, the user establishing connection with the server can interact with the new server process, so that the new server process provides service for the user.
When the server process is updated, the monitoring socket and the user connection are sent to the new server process through the old server process, the user who has established connection with the server can interact with the new server process, and the user who does not establish connection with the server can directly establish connection with the server through the new server process, so that the user can not feel the blockage caused by the update of the server process when establishing connection with the server or interacting with the server, and the use experience of the user is enhanced.
And S130, after the new server process is handed over, the new server process sends a logout notice to the old server process.
Optionally, the new server process receives a notification that the connection between the listening socket sent by the old server process and the user is completed. When the old server process sends all the monitoring sockets and the user connections to the new server process, the old server process sends a notification of the completion of sending to the new server process, and at the moment, the old server process has no user connections, and the new user request cannot be sent to the old server process. Optionally, the total number of user connections in the old server process may be obtained, and if the total number of user connections in the old server process is zero, it is proved that there is no user connection in the old server process, and at this time, the old server process sends a notification of completion of sending to the new server process.
And after receiving the notification of completion sent by the old server process, the new server process sends an offline notification to the old server process to enable the old server process to be offline, so that the new server process completely replaces the old server process to work, and the user with the established connection can update the server process without offline.
On the basis of the above embodiment, the server process updating method further includes: and if the new server process does not detect the existence of the old server process, establishing a new connection with the user when the user sends a connection request, and providing service for the user through the new connection. When the new server process is started and the existing of the old server process is not detected, the connection between the user and the server is not established at the moment, and when the user sends a connection request, the new server process establishes new connection with the user, so that the new server process can process the user request.
According to the technical scheme of the embodiment, when the new server process is started, if the new server process detects that the old server process exists, the handover notification is sent to the old server process; the new server process receives the monitoring socket sent by the old server process and is connected with the user; after the new server process is handed over, the new server process sends an offline notification to the old server process, the problem that a user can be offline when the server process is updated is solved, and the effect that the user with established connection can update the server process without offline is achieved.
Example two
Fig. 2 is a flowchart of a server process updating method according to a second embodiment of the present invention, which is further optimized based on the second embodiment, and optionally, the server process updating method further includes: when the old server process detects that the user connection exists, the old server process continues to process the user request sent by the user connection in the old server process, so that the server process is updated under the condition that the user does not sense, and the experience of the user is enhanced.
