Abstract
The invention relates to the technical field of software acquisition and installation, in particular to a method for automatically acquiring and installing software in a virtual machine. The method comprises the steps of: manufacturing a virtual machine image, arranging a virtual serial port in a default mode in the virtual machine image, and setting to run a proxy client module during starting up; sending a software installation command to the virtual serial port by a virtual machine management program; monitoring the virtual serial port by the proxy client module on the virtual machine, and receiving and analyzing a command of the serial port, wherein the command contains an acquisition address of software to be installed; if the address is valid, acquiring the software and executing silent installation by the proxy client module, otherwise, not installing. According to the method disclosed by the invention, the problems that a large quantity of virtual machine images are needed to manufacture so as to meet different service requirements, so that viruses and malicious codes are introduced to the virtual machine due to software acquisition, the software installation is complicated, and the like can be solved, and the method can be applied to the software acquisition and installation of the virtual machine.
Description
Technical field
The present invention relates to software and obtain and the field engineering field, particularly a kind of method of in virtual machine, obtaining automatically with install software.
Background technology
Cloud computing is through install software in advance for the application of virtual machine, makes the virtual machine image template to reach the purpose that generates virtual machine fast, in batches.Facing operating system and software is numerous, and can the application scenarios of service be provided through freely arranging in pairs or groups between the two the time, the virtual machine template quantity that needs to make in advance is just many, and can bring following problem:
The one, the mirror image expansion is inconvenient, when increasing a software, possibly just need to make again the virtual machine image that is complementary with operating system quantity so;
The 2nd, consuming time longer; Need in corresponding operating system on the physical machine, carry out the installation of corresponding software when making mirror image earlier; Mode through P2V derives virtual machine image then, can't reach in the P2V success ratio under 100% the situation, does consumed time like this and is undoubtedly long;
The 3rd, the approach that the user obtains software is various, and the software that obtains can't guarantee its security, possibly contain malicious code or virus in the software, in case outburst will cause great influence to the network at cloud computing center;
The 4th, let the user may maloperation take place during install software voluntarily and cause software correctly to install, perhaps dispose mislead cause software can't operate as normal.
In order to promote the efficient that virtual machine is used, strengthen the extensibility that virtual machine image is made, need a kind of customizing virtual machine mirror image and corresponding software in advance of passing through, after virtual machine moves, carry out the mode that software is installed automatically.
Summary of the invention
The technical matters that the present invention solves is to provide a kind of method of in virtual machine, obtaining automatically with install software, has solved to satisfying different service demand needs and made a large amount of virtual machine image, obtained software virus with malicious code is introduced virtual machine and software is installed problems such as complicacy.
The technical scheme that the present invention solves the problems of the technologies described above is: comprise the steps:
Step 1: make a virtual machine image, comprise a virtual serial port above, and agent client module of acquiescence operation;
Step 2: the serial ports to virtual machine sends predetermined serial port command;
Step 3: the agent client module of virtual machine is monitored the virtual serial port of appointment, resolves the serial port command that comprises the install software address of wanting; If the software address that parses is effective, execution in step 4; If the order that parses is incorrect or software address is invalid, execution in step 6;
Step 4: the agent client module of virtual machine is obtained software from the address;
Step 5: the agent client module of virtual machine is to the software executing that the gets access to installation of mourning in silence;
Step 6: install and finish.
Said agent client module comprises serial port command processing module, software acquisition module and the software installed module of mourning in silence, when virtual machine gets into operating system operation automatically later on;
Whether said serial port command processing module is a cross-platform module, receives the order of specific serial ports, and is responsible for resolving serial port command, judge and order the form and the software address that whether meet agreement to be visited;
Said software acquisition module is a module on the virtual machine that from software library, downloads, and software library can be provided by FTP or http server;
The said software installed module of mourning in silence is one and automatically performs according to the value that is provided with in advance, does not need manual intervention to go the module of install software;
The said software installed module of mourning in silence is an installed module of mourning in silence that satisfies Windows virtual machine and Linux virtual machine simultaneously.
Described serial port command form is type+separator (: :)+URI, and like 10::ftp: // 192.168.1.2/office.rar, wherein type partly keeps for the program expansion to use, and is defaulted as 10 at present, represents software address.
The write direct device file of reason machine of the order that the software that sends to the virtual machine serial ports obtains and installs.
The mourn in silence type of the automatic adapting operation of installed module system of software; Difference according to type; Windows operating system is called the msiexec.exe order of Windows Installer, and (SuSE) Linux OS calls the installation of mourning in silence of rpm order (red cap release) or deb order (debian release) order completion software.
The present invention controls virtual machine as required through serial port command and obtains automatically and automatic software installation; Can generate the virtual machine that satisfies the different business demand automatically as required from a basic virtual machine image; And need not remove manually to formulate a large amount of mirror images; When a large amount of virtual machines need be unified patch is installed, the present invention is providing great convenience property also simultaneously.Virtual machine of the present invention obtains required software from the designated software storehouse, various softwares can be a local unified management, has reduced install software in the virtual machine and introduces the risk of malicious code and virus.The order that the software that the present invention sends to the virtual machine serial ports obtains and installs directly realizes through the device file of writing physical machine, does not receive the influence of network environment, is different from the shortcoming that general software installation and upgrade procedure is subject to network.The present invention is the type of adapting operation system automatically, and being different from general software installation and upgrade procedure can only the single Windows of being used for or the restriction of Linux.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified:
Fig. 1 is the inventive method process flow diagram;
Fig. 2 is an agent client modular structure block diagram of the present invention.
Embodiment
As shown in Figure 1, make a virtual machine image earlier, comprise a virtual serial port above, and agent client module of acquiescence operation, this process can be realized by a virtual serial port that defines among the libvirt.xml, defines as follows:
<console?type='pty'?tty='/dev/pts'>
<source?path='/dev/pts'/>
<target?type='serial'?port='0'/>
</console>
Here defined a serial ports, port numbers is 0, the expression COMM1, and be mapped to physical machine /the dev/pts device file on;
Serial port command processing module in the agent client module receives serial port command and resolves its content, and this program can realize that code is following by Java Communications API:
