Specific embodiment
With reference to the accompanying drawing, embodiments herein is described.
Distributed lock is a kind of mode for controlling synchronization of access shared resource between distributed system.In distributed system
In, if having shared one or a set of resource between the different hosts of different system or same system, access this
When a little resources, generally require mutual exclusion prevent it is interfering with each other guarantee consistency, in this case, just need using arriving
Distributed lock.There are many implementations of distributed lock, as redis realizes that distributed lock, zookeeper realize distributed lock
Deng.Embodiments herein elaborates by taking the distributed lock based on redis server as an example.
Redis server is a single thread inner server, supports the data type of storage relatively more, including character
String, chained list, set and ordered set.These data types all support push/pop, add/remove and take intersection union and difference
The richer operations such as collection.On this basis, redis supports the sequence of various different modes.For guaranteed efficiency, data are all
Caching is in memory.
Embodiments herein provides a kind of timed task dispatching method and device, refering to what is shown in Fig. 1, the main body of this method
Frame includes that database server 10, redis server 20, control centre's node 30 and scheduling accept unit 40.The timing
Method for scheduling task is applied in control centre's cluster.Control centre's cluster includes multiple control centre's nodes 30, multiple tune
Degree central node 30 successively obtains distributed lock, gets control centre's node of distributed lock successfully as the first control centre section
Point.First control centre's node can obtain scheduling permission, by dispatch corresponding scheduling accept unit 40 execute it is corresponding fixed
When task, to solve to put into a large amount of human costs to timed task management and running in the prior art and error-prone technology is asked
Topic.
With reference to shown in Fig. 2-3, embodiments herein provides a kind of timed task dispatching method, and the method comprising the steps of
S101-S103:
S101, first control centre's node obtain distributed lock.
Refering to what is shown in Fig. 4, including in multiple scheduling in control centre's cluster to guarantee to execute the reliability of timed task
Heart node 30, if node 1 and node 2 successively initiate to obtain to the redis server 20 request of distributed lock, redis at this time
Server 20 is in unlocked state.It wherein initiates to request and be successfully updated to 20 unlocked state of redis server at first
The node 1 of lock state successfully gets distributed lock, and returns to 1, and node 2 learns that distributed lock is occupied by return value 1
With redis server 20 is in the lock state, therefore obtains failure, task termination, after node 1 discharges the distributed lock
It is further continued for executing and obtains operation.Our nodes 1 are referred to as first control centre's node in the present embodiment.
S102, the distributed lock based on acquisition, first control centre's node are pre- in predetermined period according to operation plan
If the time, call instruction is sent to having the scheduling for executing timed task function to accept unit.
Optionally, this method further includes step S104, reads scheduling and accepts unit list.First control centre's node is obtaining
It takes and accepts unit list firstly the need of reading scheduling before distributed lock, scheduling accepts unit list and is stored in database server
In 10, including it is all dispatch accept unit interface IP address, scheduling accept unit ID, dispatching cycle, scheduling feature description etc..It adjusts
Degree accepts unit 40 for realizing specific background business logic.Scheduling, which is stored with, in the database server 10 accepts cell columns
Table and scheduling events table, facilitate that system maintenance personnel accept unit list by monitoring and scheduling and scheduling events table can be appreciated that tune
The task execution situation at degree center.
Then first control centre's node accepts unit list pre-programmed operation plan according to the scheduling, which is
Preset time in predetermined period accepts unit ID scheduling and has execution by dispatching the interface IP address for accepting unit and scheduling
The scheduling of timed task function accepts unit.Such as preset operation plan is to sort out bill daily one o'clock of morning, can be held
It is that the first scheduling accepts unit that the scheduling of the row function, which accepts unit, wherein being daily dispatching cycle, one o'clock of morning is default
Time, scheduling feature are described as sorting out bill.Then first control centre's node need to be at daily at one o'clock of morning at this time point
Unit, which is accepted, to the first scheduling sends call instruction.It is stored in database server 10, adjusts since scheduling accepts unit list
Any one control centre's node 30 in degree center cluster can read scheduling acceptance form from the database server 10
First list and layout operation plan.
Based on the distributed lock that step S101 is got, first control centre's node is accepted according to the operation plan to scheduling
Unit 40 sends call instruction, which accepts unit 40 and execute corresponding timed task, finishing service according to the call instruction
After logic, to first control centre's node feeding back implementing result.
S103, first control centre's node receive the implementing result that the scheduling accepts unit feedback.
In step s 102, scheduling accepts unit 40 and is executed according to the call instruction of first control centre's node and determined accordingly
When task after to first control centre's node feeding back implementing result.First control centre's node receives the scheduling and accepts unit 40 instead
The implementing result of feedback.
Optionally, this method further includes step S105, updates scheduling events table according to the implementing result.The scheduling events table
It also is stored in database server 10, has recorded the event id of each scheduling events, dispatch and accept unit ID, the initiation time,
Execute the contents such as time-consuming and implementing result.A scheduler task executes completion since then.
Embodiments herein provides a kind of timed task dispatching method, ensure that each scheduler task by distributed lock
It will not be repeatedly executed, joined control centre's cluster, it is ensured that the reliability that timed task is performed may be implemented simultaneously
Unified management to multitask, developer need to only write the business realizing that scheduling accepts unit, without paying close attention to timed task
Life cycle management.While reducing human cost, artificial caused maloperation problem is decreased.
