Wherein, trigger node is a node in cluster, configuration timing or periodic task on trigger node, such as: can carry out the timing of configuration task by the crontab order of linux or periodically perform.The responsibility of this timing or periodic task makes the available server node in trigger node Stochastic choice cluster, such as: trigger node can from the server node catalogue of static configuration Stochastic choice available server node, or trigger node can obtain an available server node at random from service locator or server configuration center, then go to trigger concrete task processing logic.
Step 202, trigger node sends trigger request to above-mentioned available server node, carries the title of pending task in above-mentioned trigger request.
Step 203, available server node determines whether to perform above-mentioned pending task according to the title of pending task.
Particularly, according to the title of pending task, available server node can determine whether above-mentioned pending task is performed by self, if so, then performs above-mentioned pending task; If according to the title of pending task, available server node determines that above-mentioned pending task is not performed by self, then available server node does not perform above-mentioned pending task.
When available server node performs above-mentioned pending task, if available server node determines that pending task performed, and again perform this pending task result obtained and coming to the same thing of obtaining before, then available server node can simplify the implementation of above-mentioned pending task, such as: only can carry out pre-service to above-mentioned pending task, no longer perform concrete operation flow.
Step 204, available server node sends to trigger node and triggers response.
Particularly, if available server node is determined to perform above-mentioned pending task, then carry the instruction that available server node determines to perform above-mentioned pending task in above-mentioned triggering response; If available server node is determined not perform above-mentioned pending task, then carry the instruction that available server node determines not perform above-mentioned pending task in above-mentioned triggering response.
When available server node is determined to perform above-mentioned pending task, perform step 205; When available server node is determined not perform above-mentioned pending task, this flow process terminates.
Step 205, available server node asynchronous performs above-mentioned pending task.
In above-described embodiment, trigger node timing or periodically selection available server node, and send trigger request to above-mentioned available server node, the title of pending task is carried in above-mentioned trigger request, after receiving the trigger request of trigger node, available server node performs pending task, thus can realize the task scheduling in cluster based on single node, can decentralized task load in the cluster relatively uniformly, thus cluster server resource can be utilized better.
