php介绍

PHP即“超文本预处理器”。

PHP原始为 Home Page的缩写，已经正式更名为 “PHP: “。

php的应用php源码安装

下载地址:

配置阶段:./

执行./时出现错误提示,大部分是因为缺省相关软件导致,看提示安装即可.

当出现Thank you for using PHP.即配置完成.

编译阶段:make

在1cpu,1G内存,1G交换空间的情况下,make命令会最高占用99%的cpu资源,内存最高使用600M左右.

如果说自有的ecs配置不高的情况下,选择源码编译并不是一个好的选择.

当出现Build .即编译完成.

安装阶段:make

查看一看默认安装了哪些模块,php -m

其中发现了和这就是为什么在配置阶段会提示安装-devel,-devel的原因了.

web工作原理

是cgi的升级版,php-fpm是php-cgi的升级版,https是http的升级版.

客户端与web服务器通过超文本传输协议(等)进行通信.

web服务器与php解析器(等)通过cgi(等)进行通信.

配置nginx服务器

在nginx里配置协议的相关参数,将数据通过9000端口传递出去.

vim /usr/local/nginx/conf/nginx.conf

location ~ .php$ {
    root           /usr/local/nginx/html;
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}

生成一个测试文件

echo "" >> /usr/local/nginx/html/index.php

配置php解析器

监听9000端口进行程序解析.

php-cgi

执行命令:

/usr/local/bin/php-cgi -b 127.0.0.1:9000 -c /usr/local/php/php.ini

php-fpm

执行命令:php-fpm

vim /usr/local/etc/php-fpm.d/www.conf

listen = 127.0.0.1:9000
