Abstract
A kind of method using php program execution system orders, this method can be applied in the operation management function (such as data export, system reboot) for the operation platform realized with php language.
Description
Technical field
The present invention relates to a kind of method using php program execution system orders.
Background technology
Existing solution usually individually builds the private server of an inside, the php in the private server
Program allows execution system level order (such as exec, system function).When php programs need execution system order,
It will think to send in this private server and perform request, so as to allow private server to perform the system that php programs need to perform
Order.
Prior art has the following disadvantages：1st, need additionally deployment one (or a set of) server, increase hardware cost and
Maintenance cost；2nd, the problems such as needing to consider to connect overtime, anti-injection in realization, development cost is increased；3rd, due to service-specific
Php programs on device can perform all system commands, once cause the php programs of private server can be with control by attack
Whole server is made, huge potential safety hazard be present.
The soluble problem of this method：1st, can local disposition, without extra server resource；2nd, only need to realize one
The shell scripts of timing operation, exploit natural resources without extra；3rd, will be deleted after the running paper comprising system command,
Improve security.
The content of the invention
The purpose of patent of the present invention is to provide a kind of method using php program execution system orders, present invention use
Following technical scheme：
A kind of method using php program execution system orders, it is characterised in that this method comprises the following steps：
Step 1, the request of data backup, php of the Web page towards server are sent with the web page of user orientation server
Background program sends request；
Step 2, after the php background programs described in step 1 receive the request of web page transmission, the php programs exist
A shell script file is created under the catalogue specified；
Step 3, also there is crontab timing scripts in the server, crontab timing scripts regular check step
Php.sh script files described in rapid two whether there is, if it does not, out of service；, will if the script file is present
The php.sh script files can be performed；
Step 4, after performing php.sh script files in step 3, the database of crontab timings script and server is built
Vertical connection, the database carries out execution data backup commands, after the completion of backup, carries out delete command and deletes php.sh scripts
File.
2nd, a kind of method using php program execution system orders as claimed in claim 1, it is characterised in that step
The entitled php.sh of shell script files described in two.
3rd, a kind of method using php program execution system orders as claimed in claim 1, it is characterised in that step
In three, the frequency of regular check checks once to be per minute.
Beneficial effect：
1st, can local disposition, without extra server resource；2nd, only need to realize the shell pin of a timing operation
This, exploits natural resources without extra；3rd, it will be deleted after the running paper comprising system command, improve security.
Brief description of the drawings
Fig. 1 is the operating process view of invention.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.
A kind of method using php program execution system orders, it is characterised in that this method comprises the following steps：
Step 1, the request of data backup, php of the Web page towards server are sent with the web page of user orientation server
Background program sends request；
Step 2, after the php background programs described in step 1 receive the request of web page transmission, the php programs exist
A shell script file is created under the catalogue specified；
Step 3, also there is crontab timing scripts in the server, crontab timing scripts regular check step
Php.sh script files described in rapid two whether there is, if it does not, out of service；, will if the script file is present
The php.sh script files can be performed；
Step 4, after performing php.sh script files in step 3, the database of crontab timings script and server is built
Vertical connection, the database carries out execution data backup commands, after the completion of backup, carries out delete command and deletes php.sh scripts
File.
The entitled php.sh of shell script files described in step 2.
In step 3, the frequency of regular check checks once to be per minute.
More effectively to illustrate the present invention, will be illustrated with specific application scenarios：In this scenario, user needs
Data export operation is completed by clicking on the export button on web page.For convenience of elaboration, database service we with mysql
Exemplified by database program.
In this scene, the php programs in server can carry out data in the case where forbidding the system commands such as exec
Library backup operation (performs mysqldump orders).
After user sends out the request of data backup, php programs create a script for being php.sh under specified catalogue
File, content be mysql export (swf) command (such as：mysqldump–umysql_admin–pmysql_pwd db_name>/
data/tmp/data.sql).In the crontab programs of server, there is a script for being named as auto_check.sh per minute
Check that php.sh files whether there is, if it does, the script can go to perform php.sh files (./php.sh), now mysql
Database carries out data backup commands, after the completion of backup, carries out delete command and deletes php.sh scripts (rm-f
php.sh)。
So far, the operation that php programs complete DB Backup in the case where have disabled the system commands such as exec is realized.
The present invention can realize following effect：1st, the php programs on server need not support the system commands such as exec, increase
Add Services-Security；2nd, the sh orders for needing to perform will be deleted after having performed, even if server is attacked, sh orders
It also is difficult to be found, improves code safety；3rd, reduce intermediate link, make O＆M more convenient, avoid network problem
Influence to the sets of plan effect.
It should be understood that these embodiments are only illustrative of the invention and is not intended to limit the scope of the invention.In addition, it is to be understood that
After the content of the invention lectured has been read, those skilled in the art can make various changes or modifications to the present invention, these
The equivalent form of value equally falls within the application appended claims limited range.
Claims (3)
- A kind of 1. method using php program execution system orders, it is characterised in that this method comprises the following steps：Step 1, sends the request of data backup with the web page of user orientation server, and the Web page is towards the php backstages of server Program sends request；Step 2, after the php background programs described in step 1 receive the request of web page transmission, the php programs are being specified Catalogue under create a shell script file；Step 3, also there is crontab timing scripts in the server, the crontab timing script regular check step 2 Described in shell script files whether there is, if it does not, out of service；If the script file is present, it will performs The shell script files；Step 4, after performing shell script files in step 3, the Database of crontab timings script and server connects Connect, the database carries out execution data backup commands, and after the completion of backup, crontab timing scripts carry out delete command and deleted Except shell script files.
