Embodiment
As shown in Figure 1, be the running environment figure of IP of the present invention address automatic distribution system preferred embodiment.This IP address automatic distribution system 10 operates on a remote computer 1, and this remote computer 1 comprises memory 12, processor 14.This remote computer 1 by wireless or multiple blade server 2(of the long-range connection of cable network 3 as Fig. 1 be 3).
Described memory 12 is for data such as the source program codes of storing IP address automatic distribution system 10.
In the present embodiment, described IP address automatic distribution system 10 can be divided into one or more modules, and described one or more modules are configured to be carried out by one or more processors (the present embodiment is a processor 14), to complete the present invention.For example, consult shown in Fig. 2, described IP address automatic distribution system 10 is divided into and starts module 100, detecting module 102, module 104 and mapping block 106 is set.The alleged module of the present invention has been the program segment of a specific function, is more suitable in describing the implementation of software in remote computer 1, the description of consulting Fig. 3 about the function of each module than program.
As shown in Figure 3, be the flow chart of the preferred embodiment of IP address automatic allocating method of the present invention.
Step S10, starts the baseboard management controller BMC that module 100 is each blade server 2 and sets same initial ip address, and interval starts each blade server 2 successively at regular intervals.
In present embodiment, can be the initial ip address of the BMC of each blade server 3 by last IP available address setting in the network segment, for example, at network segment 192.168.0.0, 192.168.0.1, 192.168.0.2, 192.168.0.3, 192.168.0.255 in, first IP address 192.168.0.0 is as network number, 192.168.0.255 as broadcast address, therefore, the IP address (being IP available address) that can be configured on multiple blade servers is 192.168.0.1, 192.168.0.2, 192.168.0.3, 192.168.0.254, setting last IP available address 192.168.0.254 is initial ip address.Because have certain time interval between each blade server 2 starts, therefore can set same initial ip address for the BMC of each blade server 2, this initial ip address is for each blade server 2 of remote computer 1 remote activation, the operation that more than starts each blade server 2 generally can be not failed, but in order to prevent contingency failure, can be arranged on when certain blade server 2 starts unsuccessfully and enter immediately dormancy, and after certain hour, after (as 10 seconds), restart the blade server 2 of this startup failure.
Step S11, detecting module 102 is detected the IP address in network segment hollow spare time.In present embodiment, detecting module 102 can be from first IP available address in the network segment, and the whole network segment of traversal detecting, detects idle IP address.For example, in the time that initial ip address is 192.168.0.254, traversal is detected 192.168.0.1 in the network segment successively, 192.168.0.2, and 192.168.0.3 ..., the IP available addresses such as 192.168.0.254, detect idle IP address.
Step S12, in the time detecting IP address idle in the network segment, detecting module 102 continues to detect and judge whether to exist IP address conflict.If there is no IP address conflict, enters step 13, otherwise, if there is IP address conflict, return to step 11.For example, one of them blade server A is activated, and detect exploration 192.168.0.2 without other blade server use, so setting the IP address of this blade server BMC is 192.168.0.2, but in the process of setting IP address, another blade server B also starts shooting and explores 192.168.0.2 simultaneously, because blade server A has not yet set, so erroneous judgement 192.168.0.2 is not used, therefore also setting 192.168.0.2 is the IP address of BMC, cause IP conflict, now can make blade server B dormancy certain hour, return to again step 11 and detect in the network segment, whether there is idle IP address.
Step S13, the IP address of the BMC of the blade server 2 that module 104 is set is current startup by the above-mentioned IP address setting detecting, and start next blade server 2.
Step S14, mapping block 106, according to the IP address of the BMC of above-mentioned setting, utilizes the IP address of blade server 2 each network ports of the current startup of default mapping policy setting.For example, when the IP address of BMC of setting is 192.168.0.5, and main frame is while having 10 ports, and the IP address of automatically distributing these 10 ports is 192.168.1.5,192.168.2.5, and 192.168.3.5,192.168.y.5 ..., 192.168.10.5.
Described step S10 identifies the IP address of free time in the network segment by Auto-Sensing to step S14, and obtain this not by the IP address that uses address as the blade server 2 of current startup, realizes the automatic distribution of multiple blade server IP address.
Above execution mode is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
