Fig. 1 is the state change schematic diagram of chamber and AC Source in the embodiment of the present invention.

Specific implementation mode

Explanation of nouns：

AC Source：Programmable AC power supply.

Grub：GNU GRUB (GRand Unified Bootloader are referred to as " GRUB ") are one from GNU projects Multiple operating system startup program.GRUB is the realization for starting specification more, and it is more that it allows user that can simultaneously possess in computer A operating system, and the operating system run is wished in selection in computer starting.GRUB can be used for selection operation system partitioning On different kernels, it can also be used to these kernels transmit start-up parameter.

The following detailed description of specific embodiments of the present invention.

Present embodiment by taking Ubuntu 14.04LTS (GNU/Linux 3.13.0-24-generic x86_64) as an example into Row test, testing tool：Server one, AC Source, test main frame one, DV mono-, temperature test chamber one.

1. changing BIOS:Set server to energization Auto Power On.

2. changing Linuxg Grub settings:When unexpected shutdown, it is easy to cause system to rest on grub guiding interface, need Carriage return could enter system, at this moment change system configuration file, and vim/boot/grub/grub.cfg finds following one section, will Timeout=-1 makes timeout=2 (being more than zero arbitrary number, unit is the second) into.

fi

terminal_output gfxterm

If [" $ { recordfail } "=1]；then

This journey -1 (is changed to 2) by set timeout=-1

else

If [x $ feature_timeout_style=xy]；then

Set timeout_style=menu

3. by the external test main frame of serial ports, OCTOPUS softwares are run, state when monitoring BIOS starts (also may be used herein Equipment to meet other monitoring bios, such as the more advanced equipment of Intel ITP), the display of Connection Service device, side are recorded with DV The case where being reappeared at that time according to the time of log records when just pinpointing the problems.

4. changing system configuration file：Modification system to realize automatic shutdown after booting, and records the available machine time,

Cp/etc/rc.local/etc/rcbackup/ backup rc.local original documents/

The file that newly-built one of touch/root/log/ is used to store log/

Vim/etc/rc.loacl/ changes rc.local, and following code (two kinds of different schemes) is added inside file：

(1) how many times (number for being successfully entered system) need to be successfully started up by script design server：

(2) being powered by AC Source setting servers, (i.e. server is powered not necessarily enters system to startup how many times Number)：

date>>The available machine time of log/every time is recorded in inside log files/

Sleep 10/waiting ten seconds/

Poweroff/shutdown/

After the completion of the number of AC Source settings to be done, booting enters single user mode, executes cat/etc/ rcbackup>/etc/rc.local

5. chamber and AC Source settings.

In order to make server completely it is cold, we set server energization 5 minutes, then power off it is cold set 15 minutes, need Chamber and AC Source synchronous matchings are completed.It is first that server is cold at -5 DEG C to set 2 hours, the temperature after equipment is completely cold Degree rises to 0 DEG C, and server is powered, and (maximum time of the equipment from energization booting to automatic shutdown of shutdown in ten seconds is waited for after energization It is 5 minutes, is more than to calculate fail).In order to ensure server can be cold, temperature is reduced to -5 DEG C from 0 DEG C after device powers down, It is stood at -5 DEG C and restores 0 DEG C, then the booting that is powered after five minutes, shutdown ceaselessly recycles, and after the completion of test, server need to be in room temperature It is lower to stand two hours.

This process is as shown in Figure 1.

If equipment needs are sold in worldwide, AC Source can also be set, will be owned in the world Each test 50 times of mainstream voltage type, i.e., the amplitude and frequency of that the five minutes voltages that is powered every time need to include the class of following table Type, each type test 50 times such as following table：

6. collecting test log：A. the log ,/root/log of available machine time record, order：Wc-l/root/log can be looked into See the number being entirely switched on, concrete analysis can be calculated by excel and is switched on twice interval time, if the time must more than 25 minutes So there is the case where boot failure.When b.bios monitors log boot failures, corresponding bios leader records c.linux can be checked / var/log/syslog, by being switched on, log and bios log can only have found whether booting is normal, checks that syslog can be seen Whether shutdown has exception, bios normal boots system but system, and there is no the log normally started.D.DV can help to reappear booting Specific situation when abnormal or shutdown is abnormal.

Patent of the present invention discloses a kind of a kind of test method of test server cold-starting, by AC Source And the setting of script, after making equipment and component every time cold start it is right in the case where equipment also has residual temperature to prevent The influence of test result.This test not only starts booting to equipment and is tested, and has still carried out corresponding test to shutdown, and And it eliminates abnormal shutdown and is influenced caused by test.This test not only has hardware and component comprehensive test, Stability test also is carried out to the Linux system of non-release of some enterprise self-determinings exploitation and the bios of independent development.This Test also achieves the test to AC power supplies module and voltage compatibility.This test provides very detailed log, for finding Reproduction problem is gone to provide a great help after problem.This test can not only be tested under Linux system, Also same test can be carried out under windows systems, can only lack the syslog under the exclusive var files of a linux.This survey Examination can not only be run at linux, can also be run at windows, but it is exclusive to lack a linux syslog.There is the server that fixed Combination configures for CPU, Memor, HDD, the above survey can be done respectively with different configurations Hardware compatibility test is completed in examination.The parameter setting of this test can be changed according to user's concrete condition, such as conduction time, cold It sets the time, also chamber temperature etc..This test has carried out server comprehensive detection test from component to system, with As much as possible expose various problems.
