The alternative embodiment of the disclosure is described in detail with reference to the accompanying drawing.
To the first embodiment that the disclosure provides, i.e., a kind of embodiment of the method for smooth restarting service.The disclosure is implemented
Example is applied to first progress of work established before server resets.
For example, Nginx is the high efficiency Web service end program based on asynchronous event driven；QUIC is based on UDP
Multiplexing, 0-1RTT is supported to build the Internet transport protocol of connection；That is, QUIC is an application layer protocol, only exist
TCP, HTTP2 technology such as reliable data transmission, congestion control, data multiplex are realized on the basis of UDP；Nginx with
It is described including host process (i.e. Master process) and the progress of work (i.e. Worker process) in Nginx in the joint framework of QUIC
First progress of work i.e. Worker process；Master process is mainly responsible for management Worker process, receives outer signals；
Master process and Worker process all respectively have a main event circulation, are exactly an endless loop；The main event of Worker process
Circulation then mainly calls ngx_process_events_and_timers (), handles event and timer expiry processing；One
It may include one or more QUIC connections in a Worker process, each QUIC connection namely corresponds to a UDP socket.
The embodiment of the present disclosure is described in detail below with reference to Fig. 1, wherein Fig. 1 provides flat for the embodiment of the present disclosure
The flow chart of the sliding method for restarting service.
Step S101 obtains first service restarting information.
For example, continuing above-mentioned example, the Master process that Nginx is managed after restarting to it sends smooth restarting order, so
Afterwards, the new Worker process of Master process creation, and first service is sent to each Worker process established before restarting
Restarting information (such as NGX_SHUTDOWN_SINGAL information).
Step S102 discharges first timer according to the first service restarting information, and each UDP set monitored is arranged
The characteristic variable for connecing word saves first set of words mark.
Wherein, the first set of words mark is different from the second socket mark；The second socket mark is service
The information saved in the characteristic variable for the UDP socket that second progress of work is monitored is created after restarting；The first timer is used
It is more than the UDP socket of default first time in the response time that release is monitored.
Each first progress of work includes one or more UDP sockets, and each first progress of work has one the
One timer.
In the case where normal use, when the first timer is used to discharge the response time monitored more than default first
Between UDP socket, that is, when the request response time of some UDP socket is more than default first time, then first is fixed
When device think the UDP socket communication abnormality, to no longer manage the UDP socket, that is, do not reprocess the UDP socket
Communication information.The resource occupation that system can be reduced in this way improves response time and the processing capacity of system.
It, can be in order to improve the management to UDP socket for example, since UDP socket is a connectionless socket
A protocol stack is established, the information of each UDP socket is stored in the protocol stack, first timer is by managing the protocol stack
UDP socket in management work process, after first timer thinks the UDP socket communication abnormality, by the UDP socket
It is cleared up away from the protocol stack.
The embodiment of the present disclosure shows that first progress of work will no longer be built by the first timer of first progress of work of release
New UDP socket is found, but still continues the work of existing UDP socket in first progress of work, until all UDP are socketed
Until the work of word terminates.
The characteristic variable of each UDP socket by monitoring is set as first set of words mark；Wherein, described first
The second socket that socket mark is different from the UDP socket for creating the monitoring of second progress of work after server resets identifies,
It is exactly that UDP socket work is being distinguished in the first work by the difference of first set of words mark and the second socket mark
In process or second progress of work, to avoid new UDP socket request scheduling into first progress of work.
For example, continue above-mentioned example, in combining in framework for Nginx and QUIC, the characteristic variable of UDP socket is QUIC
The SOL_SOCKET descriptor rank of UDP socket in connection；After restarting, first progress of work by all UDP sockets
SOL_SOCKET descriptor rank is set as first set of words and identifies (such as SOL_LOCK_SOCKET), and second progress of work
The SOL_SOCKET descriptor ranks of all UDP sockets be set as first set of words mark (such as SO_LOCK_
FILTER), then the kernel module of QUIC according to the SOL_SOCKET descriptor of UDP socket identifies whether the socket is first
The progress of work, so that avoiding will be in new QUIC request scheduling to first progress of work.
In order to guarantee smooth restarting service, the embodiment of the present disclosure provides the first storage variable and the second storage variable.?
After the acquisition first service restarting information, further includes:
Step S101-1, according to first service restarting information setting the first storage variable save server resets mark.
First progress of work identifies the main flow to first progress of work by the server resets of the first storage variable save
Transmit the information of server resets.After the main flow of first progress of work obtains the information of server resets, first progress of work
The storage variable save non-serving of setting first is restarted into mark, so that first progress of work can restart to receive new first
Server resets information.
The method, further includes:
Step S103 obtains the first storage variable.
Step S104, judges whether the preservation information of the first storage variable matches with server resets mark.
Step S105, if so, setting the second storage variable save exits mark.

The operation information exited.
The method, further includes:
Step S106 obtains the second storage variable.
Step S107, judges whether the preservation information of the second storage variable matches with the mark that exits.
Step S108 discharges UDP socket and corresponding second fixed if so, after the communication of each UDP socket
When device after, into wait closed state.
After mark is exited in the main flow acquisition of first progress of work, first progress of work continues to first progress of work prison
The each UDP socket communication work listened.Each UDP socket has a second timer, which is used for
The exception information for handling UDP socket, when the operation of UDP socket exceeds preset time, then second timer is by UDP socket
Release, that is, stop the communication of the UDP socket, the resource occupation of system can be reduced in this way, when improving the response of system
Between and processing capacity.
After the UDP socket communication in first progress of work, the release release UDP socket of first progress of work
Word and corresponding second timer.
When first progress of work detects no longer remaining first timer and second timer in process, then into waiting pass
Closed state.
Disclosure application embodiment provides the method for two kinds of first progresses of work of closing.First method, the entrance
Wait closed state, comprising:
Step S108-1, setting third store variable save mark to be released.
This method waits host process to obtain third and stores variable save mark to be released, then, is closed and is corresponded to by host process
First progress of work.
Second method, described into after waiting closed state, comprising:
Step S108-1, discharges this progress of work.
This method closes own process by first progress of work.
After the second storage of setting variable save exits mark, further includes:
Step S105-1, setting the first storage variable save non-serving restart mark.
So that first progress of work restarts to receive new first service restarting information.
