[0008] sending a task execution message to the cloud node corresponding to the
cloud node
identification, wherein the task execution message comprises a download
address of the
task script, such that the cloud node can download the task script according
to the

DETAILED DESCRIPTION
[0018] Fig. 1 is a schematic flow chart of a cloud node management method
provided by
Embodiment 1 of the present invention, and the method specifically comprises
the

CA 02795782 2012-11-14
following steps:
[0019] Step 101, receive a task instruction, by a central server, wherein the
task instruction
comprises a task name and an identification of a cloud node for executing the
task.
[0020] Before step 101, according to the actual requirements of the system,
the central
server receives multiple uploaded task names and corresponding task scripts
according to
user instruction or program instruction, and saves the multiple task names and
the
corresponding task scripts in a task resource pool.
[0021] The central server receives the task instruction from terminals or
upper layer
applications through at least one interface selected from a command line
interface, a
programming interface, a network service interface or a REST interface.
[0022] The task instruction comprises configuration instruction, the
configuration
instruction comprises multiple identifications of cloud nodes, configured to
indicate
multiple cloud nodes to execute configuration task.
[0023] Step 102, according to the task name, inquire the task resource pool,
and acquire a
task script corresponding to the task name.
[0024] The central server acquires a corresponding configuration file script
according to
the configuration task included in the configuration instruction, and uploads
the
configuration script file to task script download center, receives a download
address of the
configuration file script sent by the task script download center.
[0025] Step 103, send a task execution message to the cloud node corresponding
to the
cloud node identification, wherein the task execution message comprises the
download
address of the task script, such that the cloud node can download the task
script according to
the download address, and run the task script, then return an execution result
to the central
server.
[0026] Before step 103, the central server sends a task execution message to
each cloud
node corresponding to the respective cloud node identification, wherein each
task execution
message includes download address of the configuration file script. Each cloud
node
downloads configuration file script and runs the configuration file script
respectively
according to the download address of the configuration file script, then
returns the execution
result to the central server, thus achieving the centralized configuration of
the central server
to each cloud node, and improving the configuration efficiency.

[0027] The present embodiment can achieve a centralized and unified management
for all
the cloud nodes by the central server through receiving a target instruction,
acquiring a task
script, sending a task execution message to the cloud node which executes the
task, and
receiving the execution result correspondingly, thus improving the efficiency
of
management for the cloud node cluster. Meanwhile, the task instruction sent by
the central
server only comprises the download address of the task script, but not the
task script, this
can save the network resource of the central server.
[0028] Fig. 2 is a schematic diagram of a central server provided by
Embodiment 2 of the
present invention, and the central server comprises;
[0029] a receiving module 21, configured to receive a task instruction,
wherein the task
instruction comprises a task name and an identification of a cloud node for
executing the
task;

and acquire a
task script corresponding to the task name;
[0031] a sending module 23, configured to send a task execution message to the
cloud
node corresponding to the cloud node identification, wherein the task
execution message
comprises a download address of the task script, such that the cloud node can
download the
task script according to the download address, and run the task script, then
return an
execution result to the central server.
[0032] The receiving module 21 is further configured to receive the uploaded
task name
and the corresponding task script;
[0033] the central server further comprises:
[0034] a saving module 24, configured to save the task name and the
corresponding task

certificate
encryption is established by using handshake protocol in the communication
system, and
multiple cloud nodes send the corresponding cloud node identification to the
main central
server through the established secure communication channel, such that safety
certification
and registration of each cloud node can be conducted by the main central
server, wherein
the cloud node identification comprises, but not limited to, at least one of a
