Fig. 2 is the flow chart of long-range connecting detection of the present invention.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this hair
It is bright to be described in detail.Present invention omits the description to common knowledge to avoid being unnecessarily limiting the present invention.
As shown in figure 1, a kind of method for carrying out remote testing to server based on Python of the present invention, is in control machine
The Python tests of upper execution, including control machine carry out long-range connecting test to multiple machines to be measured simultaneously, and Python detections are to be measured
Whether machine is effectively connected, and to sending bind command by the machine to be measured of connecting test, is attached, control machine testing is to be measured
Machine /available machine times of proc/uptime records, the judgement of machine starting state to be measured is carried out, is normally treated for starting state
Survey machine sets up effective connection, starts remote testing.
Specifically, the method for the invention includes following S1-S4,4 steps：
S1, control machine performs Python tests, and long-range connecting test is carried out simultaneously to multiple machines to be measured；
As shown in Fig. 2 long-range connecting detection predominantly detects two aspects：Can ping lead to, ssh connections can be carried out.
Detection can ping lead to, so-called ping is logical refer to two equipment between network be logical.In view of opening for machinery compartment
Dynamic time difference, is tested using wheel dynamic formula method here.Often wheel interval 30 seconds, 20 takes turns test altogether.So do, one can
To save the Connection Time, two ensure that in the case where that can connect, and can connect certainly.
Specifically, each ping of control machine sends out three request bags, if can obtain minimum of one response bag every time, depending on
The machine to be measured is can lead to ping, and it is pass that mark ping, which leads to testing result, carries out the detection of next machine to be measured.If three
Request bag can not all receive response, then the logical requests of second of ping are carried out after being spaced 30 seconds, response bag are received, number of repetition is most
For 20 times (being within 10 minutes that system starts the time to greatest extent).
Can ssh connections for the machine testing to be measured by the logical detections of ping：
Remote file transferring is by ssh passages, and one to carry out speed fast, and two being encrypted transmission.
Can ping it is logical on the basis of detection can carry out ssh connections, direct remote cipher key is logged in here, according to logging in
As a result the action of next step is carried out, if the log on error, then error message is pointed out, and this is to be measured for interrupt routine and Safe withdrawing
Machine.
Further, control machine record returns to the time that response bag expends by the machine to be measured of the logical tests of ping.
S2, to remotely being connected by the machine to be measured of connecting test；
Long-range connection using python paramiko modules (paramiko is the module write with python language,
Follow SSH2 agreements, support by encrypt and certification in the way of, carry out the connection of remote server).Paramiko modules are supported close
Code is logged in logs in two ways with rsa.Why need to do both trials, be due to that ssh is set on different machines
Authority is different, and particularly under root accounts, code entry is not supported substantially.Therefore for the connected mode specific to machine to be measured
Need exist for doing two kinds and log in trial, respectively code entry is attempted to log in trial with rsa, it is therefore necessary to do compatible processing
The compatibility processing refers to：Widely different between different release versions under linux system, many manufacturers are also all
The customization system of oneself has been done, has been caused under different system, the setting of SSH agreements is different, and part system does not support RSA to log in.
Here normal way is to set up connection for the first time by the way of password, and just (RSA is faster by the way of RSA is logged in afterwards
It is more stable).When it is secondary log in RSA and can not set up connection when, it should enable code entry again, and can not be as connection error at
Reason.
S3, control machine carries out state-detection to the machine to be measured of connection, and machine state to be measured normally enters S4, to state not just
Normal machine interrupt test to be measured；
Connect after machine to be measured, control machine testing/proc/uptime files, the run time of this document record system, including
System starts to the now time and the free time of system.According to time length is started, judge whether to start exception.
Specifically, machine startup duration is have recorded in the machine to be measured under linux system ,/proc/uptime, it is carried out
Detection, is to return to the time progress that response bag expends to pass through the machine to be measured of the logical tests of ping with control machine record in step S1
Compare, when the two difference is excessive, it is meant that unexpected thing is necessarily encountered in system starting process, system pole has
It improper may start, in this case, the test of machine to be measured should just be interrupted, retain test environment, it is determined that category
In, being further continued for being tested under normal circumstances.
Compared to manual test, this mode contrasted based on the time can more objectively embody test result
S4, when previous step S1-S3 result is all pass, control machine start to machine to be measured carry out remote testing and
Test returns result after terminating.
Specifically, due to can set up ssh connections, paramiko objects are now directly set up, then according to be measured
The information such as IP, the username and password of machine, the ssh connections set up between control machine and machine to be measured, and transmit test command and
Performed on machine to be measured, control machine can send multiple test commands to machine to be measured, corresponding, the multiple test results of acquisition (no matter
Correctness), and control machine is back to, shown and preserved.
Test result is shown by the shell frames of control machine, each machine to be measured there are independent shell display boxes,
It is shown separately to multiple test results.
Simply the preferred embodiment of the present invention described above, for those skilled in the art,
Without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also regarded as this hair
Bright protection domain.
