前言

• CentOS 7
• nginx1.12.2
• php5.6
• nginx已經安裝完成，且document root 目錄為/usr/share/nginx/html。

步驟

1，添加php5.6源

shell> yum install epel-release shell> rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

2，查看php5.6源

shell> yum info php56w Name : php56w Arch : x86_64 Version : 5.6.40 Release : 1.w7 Size : 9.3 M Repo : installed From repo : webtatic Summary : PHP scripting language for creating dynamic web sites URL : http://www.php.net/ License : PHP and Zend and BSD Description : PHP is an HTML-embedded scripting language. PHP attempts to make it: easy for developers to write dynamically generated web pages. PHP also: offers built-in database integration for several commercial and: non-commercial database management systems, so writing a: database-enabled webpage with PHP is fairly simple. The most common: use of PHP coding is probably as a replacement for CGI scripts.:: The php56w package contains the module (often referred to as mod_php): which adds support for the PHP language to Apache HTTP Server.

3，安裝php5.6

shell> yum install php56w php56w-fpm

4，查看php版本

shell> php -v PHP 5.6.40 (cli) (built: Jan 12 2019 13:11:15) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies

5，接下來配置/etc/php-fpm.d/www.conf，將user和group改為nginx。

shell> vi /etc/php-fpm.d/www.conf user = nginx group = nginx

6，啟動php-fpm服務

shell> systemctl start php-fpm

7，檢查php-fpm服務

ps -ef | grep php-fpm netstat -tlnp | grep 9000

8，修改nginx配置，使nginx能夠將php腳本的處理轉給php-fpm模塊。

shell> vi /etc/nginx/conf.d/default.conf --------------默認是注釋掉的，取消注釋即可。如果沒有，則添加。注意將/script改為$document_root---------------location ~ \.php$ {root /usr/share/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;}

root的值需要修改為/usr/share/nginx/html。
fastcgi_param的值需要修改為$document_root$fastcgi_script_name;。

9，nginx重載配置

shell> nginx -s reload

實際情況中，如重載nginx配置與此處給出的方式不同，自動替換成其它方式即可。

10，編輯一個測試的php程序。

shell> vi /usr/share/nginx/html/index.php ----------/usr/share/nginx/html是document_root目錄--------- <?phpphpinfo(); ?>

11，輸入index.php頁面的輸出結果

http://localhost/index.php

12，設置session目錄訪問權限

cd /var/lib/php chown -R nginx:nginx *

務必保證php-fpm的啟動賬戶（本文設置的啟動賬戶為nginx）對存放session的目錄具有讀寫權限，否則將不能正確使用session。

其它

查看可以安裝的php插件：yum list php70w*

啟動php-fpm：systemctl start php-fpm 或 /usr/sbin/php-fpm
停止php-fpm：systemctl stop php-fpm
重啟php-fpm：systemctl restart php-fpm

php-fpm配置文件：/etc/php-fpm.conf /etc/php-fpm.d/*.conf
