Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Referring to fig. 1, a processing method for a client access request provided in an embodiment of the present invention is applied to a server, where the server includes: the Nginx server used for caching the static resource and the Tomcat server used for caching the dynamic resource, and the processing method comprises the following steps:
s100, the Nginx server receives the access request sent by the client and determines a static resource access request and a dynamic resource access request in the access request.
The Nginx server is a high-performance HTTP and reverse proxy web server and also provides IMAP/POP3/SMTP service; its advantages are less occupied internal memory and high concurrency.
In implementation, the number of the servers may be 1 or more, and in the case of 1, the Nginx server and the Tomcat server are installed in the same server; in the case of a plurality of servers, the Nginx server and Tomcat server may be installed in different servers.
In an implementation, the static resource access request may include: the method comprises the steps of a hypertext markup language (HTML) request, an IMG format file request, a JS script request and a Cascading Style Sheet (CSS) request.
The dynamic resource access request may include: a JSP request, a Servlet request and a data read-write request.
The English name of HTML is Hyper Text Markup Language (HTML), i.e., hypertext Markup Language. HTML, which is a language for creating web documents and displays contents such as video, sound, pictures, character animation, and video through a Tag-type command (Tag), is used as an information presentation language of WWW, and a document described using the HTML language is required to be displayed through a WWW browser.
The IMG format is a format of an image file, which has high compression efficiency, and supports an image of an arbitrary size.
JavaScript, JS for short, is a lightweight, interpreted or just-in-time programming language with function preference.
CSS is a computer language used to represent file styles such as HTML (an application of the standard universal markup language) or XML (a subset of the standard universal markup language).
JSP, JavaServerPages deploys on the network server, can respond to the request sent by the client, and dynamically generates a Web page of HTML, XML or other format documents according to the content of the request.
Servlet is a short name of JavaServlet, is a Servlet or a service connector, and a server-side program written by Java has the characteristic of being independent of a platform and a protocol, and has the main functions of interactively browsing and generating data and generating dynamic Web content.
S110, the Nginx server forwards the dynamic resource access request to the Tomcat server based on the reverse proxy principle.
The reverse proxy is that the Nginx server is used as a proxy server to receive the access request of the client, and then the access request is forwarded to a Tomcat server on the internal network; and returns the result obtained from the Tomcat server to the client that sent the access request.
S120, the Nginx server searches the static resource corresponding to the static resource access request in the static resource cached by the Nginx server.
In implementation, static resources may be cached in the/usr/local/webapps directory of the Nginx server.
S130, after receiving the dynamic resource access request, the Tomcat server searches the dynamic resource corresponding to the dynamic resource access request in the dynamic resource cached by itself.
In an implementation, the dynamic resource may be cached under the webpps/web/directory of the Tomcat server.
The first embodiment is as follows:
prepare an os server of Centos 7.6, configure firewall to open 8080 port pass.
Downloading the JDK compression packet, wherein the path after decompression is as follows: the method comprises the following steps of/usr/local/java, and environment variables are configured in the system, wherein the environment variables comprise: and environment variables such as JAVA _ HOME, PATH, CLASSPATH and the like, and the restarting server takes effect.

Downloading an installation package of Tomcat, decompressing, wherein the path is/usr/local/Tomcat, the distribution port is 8080, and the program is started up and started up automatically.
Jsp dynamic page is established, and the function of the code is to display the current time in real time and load a static picture.
Creating a folder of web/img/in Tomcat root directory webapps for storing pictures, and copying a test.jpg graph into the folder with the following path: jpg/webpps/web/img/test
After starting Tomcat, the browser enters the web address: jsp, http:// IP:8080/web/index. jsp, dynamic time is shown, as well as still pictures.
Nginx is configured, the access request is intercepted through configuration Location, all dynamic resource access requests are handed to Tomcat for processing, and other static resource access requests such as HTML, JS and CSS are processed by Nginx.
In the configuration code of the Nginx, a directory accessed by the Nginx is specified, namely the directory where the static resource is located is as follows: /usr/local/webapps, specifying that these static resources have a cache time of 30 days at the client browser.
