Abstract
The invention provides a method for initializing the user name and the password of a virtual machine based on a virtual machine template, and relates to the field of cloud computing. The method comprises the steps of packaging the user name and password information uploaded by a foreground into an ISO file; and inserting a virtual drive after the virtual machine is established by using the template, wherein after starting up, the virtual machine automatically calls the file in the ISO to set the user name and the password of the virtual machine. The method is optimized based on the prior art, thus the run time can be completed within 30 seconds.
Description
Technical field
The present invention relates to cloud computing field, relate in particular to a kind of initialization virtual machine user based on virtual machine templateThe method of name password.
Background technology
Cloud computing (cloudcomputing) be the related service based on internet increase, use and pay mouldFormula, being usually directed to is provided dynamically easily expansion and is often virtualized resource by internet. Cloud computing is logicalCross and make Computation distribution on a large amount of distributed computers, but not in local computer or remote server, enterpriseThe operation of data center will be more similar to internet. This makes the enterprise can be by resource switch to the application of needs,Access computer and storage system according to demand. At present virtual is a kind of mainstream technology that realizes cloud computing.
Virtual (Virtualization) is the term of a broad sense, refers to that computing element is on virtual basisThe upper operation in upper instead of real basis, be one for streamlining management, optimize the solution of resource. AsSpacious, penetrating office building, the wall that whole floor is not fixed, user can construct with same costMore autonomous applicable working space, and then save cost, performance space peak use rate.
The cloud platform of current use Intel Virtualization Technology on the market has two kinds of modes to create virtual machine substantially:
(1) create blank virtual machine, then client manually inserts ISO file, installing operating system;
(2) create virtual machine by template way, in template, from tape operation system, client does not need manual installation.
First kind of way is more flexible, and client can independently arrange system, but threshold is relatively high, more complicated.The second way is relatively convenient, but underaction, as virtual machine user name password etc. cannot be before installationConfirm.
Summary of the invention
For the above second way, the present invention proposes a kind of initialization virtual machine based on virtual machine template and useThe method of name in an account book password.
The present invention adopts and creates ISO file and insert virtual machine CD-ROM drive → virtual machine carry ISO → virtual machine and carry outInitialize user's script three steps and realize initialization virtual machine user name password.
User name, encrypted message that foreground is uploaded are encapsulated into ISO file, and use template establishment to complete at virtual machineRear insertion virtual drive, the file in can Automatically invoked ISO after virtual machine start, arrange virtual machine user name,Password.
Need to first make template, derivation template after template construct completes, is used the mould creating while creating virtual machinePlate creates virtual machine.
The self-triggered program of Linux virtual machine based on (SuSE) Linux OS, first carry ISO, carries out respective footThis.
Use virtual machine template and insert ISO file mode, ensure the correct transmission of parameter and call.
Windows virtual machine, based on CloudBase-Init, is revised wherein correlative code, makes it need local tuneWith adding user, user cipher plug-in unit being set, initialize virtual machine user name password.
The self-triggered program of Linux virtual machine based on (SuSE) Linux OS, first carry ISO, carries out respective footThis.
The invention has the beneficial effects as follows.
Windows virtual machine uses CloudBase-Init to initialize virtual machine user name password, stillThe time of implementation of CloudBase-Init acquiescence approximately needs 10 minutes. This method is optimized it, makes operationTime can complete in 30 seconds.
This method is not only applicable to initialize virtual machine user name password, under host name setting, Linux, upgradesThe local cache of apt-get, the size of adjustment file system also can adopt the method.
Brief description of the drawings
Fig. 1 is request flow chart of the present invention.
Detailed description of the invention
Content of the present invention is carried out to more detailed elaboration below:
(1) template construct
Window template:
1, installCloudBaselnit
2, enter C:/ProgramFiles/CloudbaseSolutions/Cloudbase-lnit/config, amendmentCloudbase-init-unattend，coNf file, willmetadataservicesBe revised asmetadata_services＝cloudbaseinit.metadata.service.configdriver.ConfigDriveServiceAnd delete next
3, enter C:/ProaramFiles/Cloudbasesolutions/Cloudbase-lnit/Python/Lib/site-Packages/cloudbaseinit/utils catalogue, amendment network.py: by MAX_URL_CHECK_RETRIES=3,Be revised as MAX_URL_CHECK_RETRIES=O
4, the new compiling of electricity network.py file python-m after amendmentpycompilenetwork.py
5, amendment factory.py enters C:/ProgramFiles/Clpudbasesolutions/Cloubase-Init/Python/Lib/site-packages/cloudbaseinit/plugins, amendment factory, py, by default in optsContent only retainsUserDataPluginWithSetUserPasswordPlugin, all the other deletions. Recompilate factory.py
6, amendment init.py. enters C:/ProgramFiles/Cloudbasesolutions/Cloudbase-Init/Python/Lib/site-packages/cloudbseinitCatalogue, amendment init.py, willconfigurehosIn t functionself.checklatestversion() and if partial content are below deleted
7, enter C:/ProgramFiles/Cloudbasesolutions/Cloudbase-init/Python/Lib/site-Packages/cloudbaseinit/metadata/ catalogue, amendment factory.py file, in the default in optsHold and deleteHttpServive, recompilate.
Attention: need use keeper to enter dos when compiling; When compiling, usecloudbaseThe python carrying, does not fill againpython！！！！
When revised file, may not under current directory, preserve, need be saved in behind other positions again copy to current directory.And then compiling
Linux template (taking centos as example)
1, newly-built/mnt/media catalogue, gives authority 777
2, amendment/etc/rc.d/rc.local file, adds following content:
mount-tiso9660-oloop/dev/cdrom/mnt/media
cat</mnt/media/openstack/latest/meta_data.json|xargs-n1useradd-m
chpasswd</mnt/media/openstack/latest/user_data
pwconv
3, use ln threaded file: enter/etc/rc2.d catalogue, is used ln-s/etc/init.d/cloudInitUser.sh.S99InitUser
Derivation template after template construct completes.
(2) create virtual machine
While creating virtual machine, use the template establishment virtual machine creating, and fill in user name, password, request is pressedAccompanying drawing 1 flow performing, can realize the initialization of user name password.
Claims (3)
1. the method for the initialization virtual machine user name password based on virtual machine template, it is characterized in that, user name, encrypted message that foreground is uploaded are encapsulated into ISO file, and after using template establishment to complete, virtual machine inserts virtual drive, file after virtual machine start in meeting Automatically invoked ISO, arranges virtual machine user name, password.
2. method according to claim 1, is characterized in that, first makes template, and derivation template after template construct completes is used the template establishment virtual machine creating while creating virtual machine.
3. method according to claim 2, is characterized in that, the self-triggered program of Linux virtual machine based on (SuSE) Linux OS, and first carry ISO, carries out corresponding scripts.
