Specific embodiment
Below in conjunction with embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only some embodiments of the invention, rather than whole embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments shall fall within the protection scope of the present invention.
Embodiment one,
As shown in Figure 1, a kind of telephone expenses back-end platform of distributed deployment of the invention comprising the webpage for sending request is clear
Look at device, storage, management and access data mysql database, realize reverse proxy, processing static requests, index file and
The Nginx server of automatic indexing realizes the uWSGI server of WSGI agreement, uwsgi and http agreement, realizes business processing
The Django server of process realizes the WSGI interface of protocol conversion between uWSGI server and Django server.
Wherein, specific request processing flow are as follows: http of the web browser to Nginx server for services device resource
Request, Nginx server receives http request and analysis request, if static requests, then reads the quiet of Nginx server configuration
State file directory and the resource for returning to request, if dynamic requests, then all solicited messages are transmitted to by Nginx server
UWSGI server, uWSGI server receives request, and is transmitted to WSGI interface, and WSGI interface takes according to request call Django
Some file or function being engaged in device, data and processing in Django server calls mysql database, after having handled
Django server gives return value to WSGI interface, and return value is packaged by WSGI interface, is transmitted to uWSGI server,
UWSGI server is transmitted to Nginx server after receiving, and return value is finally returned to web browser by Nginx server.
Nginx server is a lightweight, high-performance, the HTTP and reverse proxy service that stability is high, concurrency is good
Device, in the present embodiment, the function of Nginx server mainly have following three points function:
First point, it is mainly used to act on behalf of the destination server to be accessed, can be turned according to different canonical using different
Hair strategy, in the present embodiment, the forwarding strategy that Nginx server uses is: if request is static requests, reading service device
Dynamic requests are transmitted to uWSGI server if request is dynamic requests by disk；
Second point is used for load balancing, mostly needs in high concurrent using principle exactly shares data traffic
It is executed to multiple servers, mitigates the pressure of every server, multiple servers complete task jointly, to improve number
According to handling capacity, the present embodiment is exactly the request that high concurrent is undertaken by above-mentioned principle；
Thirdly, dynamic requests and static requests are separated, suitable server process is requested accordingly, makes entirely to take
The performance, more efficient for device system of being engaged in.Nginx server does different forwardings to different requests according to configuration, this is dynamic point
From basis.The corresponding static resource of static requests can be placed directly on Nginx server and buffer, dynamic requests by
UWSGI server process.
UWSGI server may be implemented the agreements such as WSGI agreement, uwsgi and http agreement, and have ultrafast performance,
Low EMS memory occupation, more app management, detailed journal function and height may customize feature, in the present embodiment, mainly for the treatment of
The dynamic requests forwarded by Nginx server, and realize with Nginx server with uwsgi protocol communication.
WSGI interface, full name Web Server Gateway Interface or Python Web
ServerGateway Interface is between the Web server and web application or frame defined for Python
The simple and general interface of one kind.In the narrow sense, WSGI interface is a Gateway, that is, gateway, the effect of gateway
Exactly converted between agreement.WSGI interface is as one between Web server and web application or application framework
The interface of kind low level, to promote the common ground of portable Web application and development.WSGI is like a bridge block, and in succession web on one side
Server, another side are ined succession the application of user, and WSGI has two sides: " server " or " gateway " side, and " application program " or
" application framework " side.Service side calls application side, provides environmental information and a call back function (is supplied to application program
For message header is passed to server side), and web content is received as return value.WSGI interface middleware realizes simultaneously
Two sides of API, therefore can be serviced in WSGI and play conciliation between WSGI application: for the angle of WSGI server,
Middleware plays the part of application program, and for the angle of application program, middleware plays the part of server.
Django is a WEB Development Framework, can develop web project with it, and web needs server to run,
Such as common nginx server, apache server and uWSGI server etc., these servers be merely responsible for operation program (by
The project that django writes), user requests on the server that can be sent, and then server requests Django, Django to return corresponding
Result to web server, be then returned to user.In the present embodiment, Django is as application server, abbreviation Django
Server, Django server are closed in each query steps using cur.close () function and conn.close () function
With the connection of mysql database, avoid occupying database connection number for a long time；Per thread in Django server terminates
When, thread is turned off using sys.exit (0) function, avoids occupying thread.It, can be with by turning off connection and the thread of database
High concurrent is provided for server to support.
Mysql database is a relevant database management database, is saved the data in different tables, rather than
All data are placed in one big warehouse, which adds speed and improve flexibility.Mysql database by one or
Multiple table compositions, one of table include gauge outfit, column and row, value and key, and gauge outfit is the title of each column；It is classified as with phase
With the set of the data of data type；The every a line of behavior is used to describe the specifying information of certain record；Value is capable specifying information,
Each value must be identical as the data type of the column；The value of key has uniqueness in working as forefront；Several row and columns composition one
Open list, several list composition data libraries.In the present embodiment, it when mysql database creation list, is driven using innooDB
Dynamic selection list, commonly inquires on key assignments in list and indexes, can quickly read the data in mysql database.
In the present embodiment, for Nginx server as forwarding agency, uWSGI server is responsible for the distribution of multithreading task,
Django server process dynamic requests.In the present embodiment, had using the benefit that Django is used alone in uWSGI+Django ratio:
The concurrency of support is higher, facilitates management multi-process, plays the advantage and improving performance of multicore, because of uwsgi agreement ratio
WSGI agreement is advantageous；And Nginx+uWSGI+Django ratio uWSGI+Django is advantageous in that nginx can provide forwarding generation
Reason, improves the safety of kernel program, the telephone expenses back-end platform built by Nginx+uWSGI+Django can be in 4 core 8G
Standard server configuration under, bear the peak value of 100,000 single request/hours, and the cpu memory usage of server can't
It runs full.
Embodiment two,
On the basis of example 1, the present embodiment provides after a kind of telephone expenses based on Nginx+uWSGI+Django composition
