First, Introduction1. UnderstandingEncrypted Web page (HTTPS): tcp:443 plaintext Web page (HTTP): site can be found on the latest website server usageHypertext Transfer Protocol (Http,hypertext Transfer Protocol) is one of the most widely used network protocols on the Internet. All WWW documents must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages2. ApacheApache HTTP Server (Apache) is an open source Web server of the Apache Software Foundation, which can be run in most computer operating systems, and is one of the most popular Web server-side software due to its multi-platform and security-wide use. features are as follows: 1, support the latest http/1.1 communication protocol 2, has a simple and powerful file-based configuration process 3, support the Common Gateway Interface 4, support IP-based and domain-based virtual host 5, support multiple ways of HTTP Authentication 6, Integrated Perl processing Module 7, integrated proxy Server Module 8, Support for real-time monitoring of server status and custom server log 9, support server-side include directive (SSI) 10, support Secure Socket Layer (SSL) 11, provide user session process tracking 12, support FastCGI13, through third-party modules can support Javaservlets3. official website # yum Install httpd*--Install httpd Service # HTTPD-T--Check configuration file Correctness # rm-rf/etc/httpd/conf.d/welcome.conf-- Remove the Welcome screen, because Httpd-manual is installed, so you can accesshttp://ServerIp/manual4. Run in two modes: Prefork,workerprefork mode:Prefork is the default (default) MPM on the UNIX platform,use multiple child processes, with only one thread per child process。 Each process can only maintain one connection at a certain time,high efficiency, but large memory consumption。 This multi-path processing module (MPM) implements a non-threaded, pre-derived Web server that works in a similar way to Apache 1.3. It is suitable for systems that do not have a thread-safe library and need to avoid threading compatibility issues. It is the best mpm to require each request to be independent of each other, so that if a request has a problem it will not affect the other request.worker mode:Worker usemultiple child processes, with multiple threads per child process, each thread can only maintain one connection at a certain time,low memory footprint for high-traffic HTTP servers。 The downside is that if a thread crashes, the entire process will "die" with any of its threads, so ensure that a program must be recognized by the system as "every thread is safe" at run time. This multi-path processing module (MPM) enables a network server to support mixed multithreaded multi-process. Because a thread is used to process requests, a large amount of requests can be processed, while the overhead of system resources is less than the process-based MPM. But it also uses multiple processes, each with multiple threads, to get the stability of the process-based MPM. # httpd-l--View run mode, default to prefork.c# mv-v/usr/sbin/httpd{,.prefork}--Backup prefork mode # mv-v/usr/sbin/httpd{.worker,}--Use WOR Ker modeSecond, the configuration file detailed1. Global Environment ParametersServertokens OS--Displays Apache version and operating system name when the server responds to host header (header) InformationServerRoot "/ETC/HTTPD"--The base directory of the server, in general it will contain the conf/and logs/subdirectories, and the relative paths of other configuration files are based on this directory. Pidfile Run/ process number file location of the first httpd process (the parent process of all other processes). Timeout 60-Disconnect the connection if no data is received or sent after 60 secondsKeepAlive OFF--The ability to keep connections is not used by default, that is, a client requests a connection to respond to only one file, and recommends allowing Maxkeepaliverequests 100--When maintaining the connection function, set the maximum amount of time that the client can respond to a request connection and disconnectKeepAliveTimeout 15--When using the Keep-connect function, two adjacent connections have a time interval of more than 15 seconds to disconnect the connection................. Listen 80--The port number that the server listens to, the listening port can be opened more Include conf.d/*.conf--Include all conf-terminated configuration files in the/ETC/HTTPD/CONF.D directoryUser Apache--users of child processes that provide servicesGroup Apache--User groups for child processes that provide servicesServerAdmin [email protected]--Administrator's email addressServerName site name (host name of the site)Usecanonicalname offdocumentroot "/var/www/html"--Set the Web document root directory, but you can use symbolic links and aliases to point to other locations and, if not absolute paths, are assumed to be relative to the ServerRoot path2. Path Control ParametersDirectoryIndex index.html Index.html.var--Site default page filename, left priorityAccessfilename. htaccess--Specifies the name of the protected directory configuration file---------------------------------------------------------------------------------------------------------<directory directory-path> --used to encapsulate a set of instructions that are only valid for a directory and its subdirectories. for a directory on the file system Options Indexes followsymlinksallowoverride Noneorder allow,denyallow from Alldeny from</directory >Directory-path-- can be the full path to a directory, or a wildcard string that contains the Unix shell matching syntax. In a wildcard string, "?" Matches any single character, "*" matches any sequence of characters. You can also use "[]" to determine the range of characters. Regular expressions can also be used after the "~" character Options-The value of this directive can be "None", "all", or any combination of the following options: Indexes(Previous '-', the function of closing the site column directory, or vice versa); includes ; Followsymlinks;symlinksifownermatch;execcgi;multiviews allowoverride -Controls the instructions that are placed in the. htaccess file. It can be all,none (no configuration in any. htaccess), or a combination of the following commands: Options; FileInfo; Authconfig; Limit Order,allow,deny -control who can access the service.

But it can be accessed directly by entering the URL (even if you have an account and password). 4.

6.2. Test your own configured certificateHttps:// But the certificates we create ourselves are not trusted in the browser;The certificate status is also "because the CA root certificate is not in the trusted Root Certification Authorities store, so it is not trusted." "       

We need to manually import our own created certificate (TEST.CRT) to Trusted Root Certification Authorities && trusted Publishers in our browser. The following steps are listed in Google Chrome:


Next, we will pop up a few more dialog boxes, we click "Next"-"done"-"yes". It's OK.

   at this point, use your browser to open our web site and view the certificate's status "There is no problem with this certificate".
