Adding PHP parsing to the httpd configuration file

Modify the Apache configuration file so that Apache can parse it using PHP
httpd configuration file in/usr/local/httpd/conf/httpd.conf path
Modify the following configuration parameters in the httpd configuration file, and look for the key character configuration in the httpd.conf configuration file.

[[email protected] httpd]# vim conf/httpd.conf~ There are two PHP modules installed, you need to comment out a PHP module. Because httpd cannot load two PHP modules at the same time LoadModule php5_module modules/libphp5.so??? #LoadModule Php7_module modules/ Libphp7.so the comments of the ServerName line, which allows httpd to start and access the default page correctly # ServerName gives the name and port that the server uses to identify it Self.# This can often is determined automatically, but we recommend you specify# it explicitly to prevent problems during startup.## If Your host doesn ' t has a registered DNS name, enter its IP address here.

Check the httpd configuration file is correct, test configuration content, here is the use of a habit, after modifying the configuration file first check for errors in the configuration file, if the configuration file is incorrectly configured and does not check the direct restart service, will cause the service startup error service start termination, Causes the service to stop providing access, which causes the service to be inaccessible for a short period of time, requires checking the configuration file and restarting the service, and using graceful to reload the service configuration

httpd PHP parsing, write a PHP test file content in the HTTPD web directory

[email protected] httpd]# cat htdocs/index.php

<?phpphpinfo();?>

PHP page parse the access results correctly example: httpd loaded PHP module, and return the page header information, the response of the service-side resolver is php/5.6.37

[[email protected] httpd]# curl -I 192.168.1.233/index.phpHTTP/1.1 200 OKDate: Sun, 29 Jul 2018 09:22:59 GMTServer: Apache/2.4.33 (Unix) PHP/5.6.37X-Powered-By: PHP/5.6.37Content-Type: text/html; charset=UTF-8

If you write a PHP test page but cannot display the PHP test page, you need to check it out in the following ways:
PHP can not parse, first check whether there is a PHP module, whether in the httpd configuration file has php load configuration parameters, whether to write to parse the PHP configuration parameters, test whether to specify the index page of the homepage

HTTPD Virtual Host Configuration
About Virtual hosts:
A server can run multiple Web sites, one host multiple domain names specify different sites, each site is a virtual host

Modify the resolution file of Windows, this is used only as a test, modified file path in C:\Windows\System32\drivers\etc\?, open the Hosts file with a notebook, the format of the IP? Domain name, you can specify that an IP has multiple domain names
When the client accesses the httpd of the default virtual host that is not configured, resolves any IP addresses of the domain name if the IP address pointing to the server is directly accessible to the HTTPD's default host

Configure the HTTPD virtual host, open the virtual host profile, modify the conf/httpd.conf configuration file, remove comments or add:

# Virtual hostsInclude conf/extra/httpd-vhosts.conf

When the virtual host configuration is turned on, the site configuration defined in the original master profile fails to stop access, and the settings in the virtual host configuration file are in effect. The following are examples of virtual host configuration items:

[[email protected] httpd]# cat conf/extra/httpd-vhosts.conf # Virtual Hosts## Required modules: mod_log_config-------------------------------省略---------------------------------------<VirtualHost *:80> ?  DocumentRoot "/usr/local/httpd/docs/abcd.com" ? ? <---网站网页加载路径 ?  ServerName abcd.com ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? <---解析的虚拟主机名 ?  ServerAlias www.abcd.com ? ? ? ? ? ? ? ? ? ? ? ?  <---虚拟主机域名 ?  ErrorLog "logs/abcd.com-error_log" ? ? ? ? ? ? ?  <---虚拟主机错误日志 ?  CustomLog "logs/abcd.com-access_log" common ? ? ? <---虚拟主机访问日志</VirtualHost><VirtualHost *:80> ?  DocumentRoot "/usr/local/httpd/docs/123.com" ?  ServerName 123.com ?  ServerAlias www.123.com ?  ErrorLog "logs/123.com-error_log" ?  CustomLog "logs/123.com-access_log" common</VirtualHost>

Create a Web page store directory for the virtual host and use Apachectl to check the configuration file and reload the httpd configuration

[[email protected] httpd]# mkdir -p /usr/local/httpd/docs/abcd.com[[email protected] httpd]# mkdir -p /usr/local/httpd/docs/123.com[[email protected] httpd]# /usr/local/httpd/bin/apachectl -tSyntax OK[[email protected] httpd]# /usr/local/httpd/bin/apachectl graceful

On the Windows side and Linux side briefly authenticate the virtual host access results:

Using the Curl command to access the contents of a Web page under Linux, the results are as follows:

[[email protected] abcd.com]# curl -x192.168.1.233:80 abcd.comabcd.com[[email protected] abcd.com]# curl -x192.168.1.233:80 123.com123.com
