Static compilation of Web Server appweb (with matrixssl support) for arm9-+ Linux

Among the many web servers, there are many lightweight Web servers, such as BOA, thttp, and Lighttpd, however, for Embedded Web servers with high security and convenience for later web development and development, the Web servers mentioned above are too thin. the company requires that embedded products (such as routers) be managed and developed on the web with certain security performance. compared with several lightweight, embedded web servers. the final recommendations were made by Michael o'brien's two Web servers: GoAhead (http://webserver.goahead.com/webserver/webserver.htm) and appweb (http://www.appwebserver.org/downloads/appWeb/download.php ). The former is part of goahead's embedded management framework product. This software package is mainly used to solve future embedded system development problems. This web server is very small, the size of the compiled Windows CE version is less than 60 kb, and its output is usually oriented to some small screen devices. GPL & Commercial license. It claims to be the leader of embedded web server in the future. The latter is the first product of mbedthis company created by Michael o'brien, GPL & Commercial License. mob described it as mini-Apache. in the process of use, we can also feel this: Through appweb. the conf configuration file supports dynamic loading of modules. the above two Web servers are the first choice for most routers and other devices. The following describes the main features of these two Web servers: Appweb features (too lazy to translate ): Appweb is a standards-based embedded HTTP server that has a wealth of features including: 1, standards compliant HTTP/1.1 web server core 2, embeddable in applications and devices (supports xip) 3, dynamically loadable modules 4. Embedded Server Pages (ESP) for dynamic content (in fact, it is used to support ASP modules like goahead) 5. session State Data Management 6. server-side embedded Javascript 7. Secure Socket Layer (SSL): (OpenSSL and matrixssl) 8, in-process CGI as well as traditional CGI 9. romable web pages and configuration files 10, digest authentication ******** 11. HTTP client program and Library 12, extensive logging 13. Fastest performance in its class 14. modular source code and documentation provided 15. APACHE-style configuration, logging, and single-and multi-threaded apps. Because the company's products should consider security issues, we must point out the SSL 3.0 implementation of matrixssl. matrixssl is an SSL designed for embedded products, which is much smaller than OpenSSL. GPL & Commercial License occupies about 50 k ram. In terms of performance, a 68040 processor of 24mh Z can respond 20 times/second, and a 266mhz Pentium processor can respond 50 times/second. It has the following features: 1. Support for ASP 2. Supports embedded Javascript 3. Standard CGI execution 4. Memory CGI processing gofroms 5. Extended APIs 6. Fast response. More than 50 requests can be processed per second. 7. fully compatible with the standard 8. If SSL is not included, only 60 kb of memory is required. If SSL is included, KB of memory is required. 9. The web page may exist in the ROM or file system. 10. Supports multiple operating systems, including ECOs, Linux, lynxos, QNX, VxWorks, WinCE, and PSOs. Goahead requires you to specify goahead on the homepage when using it. I think this is not very good, so I mainly transplanted appweb. it may be that Chinese people use it less and only see one post. for more information, there are still many problems and SSL is not supported. later, I read the English document, read the relevant questions on the appweb forum, and finally solved a lot of questions. I successfully transplanted them to at91rm9200dk + linux. in order to avoid detours, the original is a rare one. Today, it is suspended. I think it should be more detailed.

Make The dynamic link library libmatrixssl. So and static Link Library libmatrixsslstatic. A will be generated in the current directory. 8.

A static library file. in this case, specify -- With-matrixssl-libs = libmatrixsslstatic. 9 make In this process, the three function undefined errors in src/OS/Linux. C under the matrixssl source code will appear. In this case, we will comment out the relevant sections and then OK. Line 123: pthread_mutexattr_init () Line 125 pthread_mutexattr_settype (); Line 135 pthread_mutexattr_destroy () After successful make, the appweb and appweb. conf files will be generated under the appweb directory. In addition, there are some keys required for matrixssl operation. Mkdir/usr/local/nfs: These files are: appweb (BIN), appweb. conf (configuration file), mime. types, directory web (DocumentRoot), server. Key. Pem, server. CRT, server. Key 10 enable the NFS service: Modify the/etc/exports file as follows: /Usr/local/nfs * (RW, sync, root_squash) # Service protmap start # Service NFS start # Showmount-a view the shared and accessed Directories Mount NFS on the Development Board (ensure that the developed IP address and host address are in the same network segment ): # Mkdir/tmp/nfs # Mount-t nfs hostip:/usr/local/nfs 11. Run appweb and enable Web Services ./Appweb-F appweb. conf If an error occurs, modify the appweb. conf configuration file according to the error message. Access the Web service provided by appweb on the PC, and enter the IP address and port number of the target board in Firefox. Http: // 10.78.28.218: 80/ Https: // 10.78.28.218: 4443/ If the access fails, modify the appweb. conf configuration file. PS: The appweb and goahead chief architect, the founder of mbedthis, later pointed out the three functions that I commented out at the appweb Forum: If you build matrixssl with multithreading, then you need to build appweb with multithreading. I wocould not recommend just commenting out those pthread lines. Regarding linking statically, you are right to use a static version of the matrix SSL library. Michael Therefore, we only need to choose -- with -- multi-thread When configuring appweb to solve the problem of undefined three functions. Later, Michael added: Those APIs are part of pthreads the Linux multithreaded library. They are not part of appweb.
