11.10-11.12 安装PHP5

>PHP（Hypertext Preprocessor）英文超级文本预处理语言。PHP 是一种HTML内嵌式的语言，是一种在服务器端执行的嵌入HTML文档的脚本语言。官网：www.php.net，能用PHP7就用PHP7

PHP工作原理

将PHP的配置文件移动到./configure时指定的目录：

[root@cham002 php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini

PHP在系统中是作为Apache的一个模块被调用的，所以不用执行名启动该PHP。

查看Apache的模块：

# /usr/local/apache2.4/bin/apachectl -M……dir_module (shared) alias_module (shared) php5_module (shared)

说明： 安装完成PHP后会在Apache中自动添加相应模块，同时在Apache配置文件/usr/local/apache2.4/conf/httpd.conf中也会自动添加相应配置内容。

11.13 安装PHP7

工作原理

将PHP的配置文件移动到./configure时指定的目录：如php5

查看Apache加载的PHP模块： 

[root@cham002 php-7.1.6]# /usr/local/apache2.4/bin/apachectl -MAH00558: httpd: Could not reliably determine the server's fully qualified domain name, using fe80::6f15:52d3:ebeb:e193. Set the 'ServerName' directive globally to suppress this messageLoaded Modules: core_module (static) so_module (static) http_module (static) mpm_event_module (static) authn_file_module (shared) authn_core_module (shared) authz_host_module (shared) authz_groupfile_module (shared) authz_user_module (shared) authz_core_module (shared) access_compat_module (shared) auth_basic_module (shared) reqtimeout_module (shared) filter_module (shared) mime_module (shared) log_config_module (shared) env_module (shared) headers_module (shared) setenvif_module (shared) version_module (shared) unixd_module (shared) status_module (shared) autoindex_module (shared) dir_module (shared) alias_module (shared) php5_module (shared) php7_module (shared)

此时Apache默认加载两个PHP模块，那么为了正常使用需要通过编辑Apache的配置文件来指定其工作时默认调用哪个PHP模块（加（#）注释掉其中一个调用参数即可）：
