配置Nginx来支持php

1. 安装php7     
   下载地址：https://secure.php.net/downloads.php
   这里下载的是：wget http://ar2.php.net/distributions/php-7.0.6.tar.gz
   下载之后解压并进入在解压文件中
   安装：./configure  –enable-fpm (enable-fpm参数即可开启PHP-FPM)  ->  make && make install
   (PHP在 5.3.3 之后已经讲php-fpm写入php源码核心了)
   默认安装目录:

   root@iZ25fm7iewtZ:/php-7.0.6# make install
   Installing shared extensions:     /usr/local/lib/php/extensions/no-debug-non-zts-20151012/

   You may want to add: /usr/local/lib/php to your php.ini include_path

   ln -s -f phar.phar /usr/local/bin/phar

2. 安装Nginx，见http://www.cnblogs.com/jecyhw/p/5505474.html
3. nginx整合php-fpm
   1. 启动php-fpm： /usr/local/sbin/php-fpm

   报错
   [18-May-2016 18:07:58] ERROR: failed to open configuration file '/usr/local/etc/php-fpm.conf': No such file or directory (2)
   [18-May-2016 18:07:58] ERROR: failed to load configuration file '/usr/local/etc/php-fpm.conf'
   [18-May-2016 18:07:58] ERROR: FPM initialization failed

   到/usr/local/etc/目录下，将php-fpm.conf.default拷贝一份成php-fpm.conf

   root@iZ25fm7iewtZ:/# cd /usr/local/php/etc/
   root@iZ25fm7iewtZ:/usr/local/etc# cp php-fpm.conf.default php-fpm.conf

   然后在编辑php-fpm.conf配置文件

   ;最后一行改成如下
   include=/usr/local/etc/php-fpm.d/*.conf

   进入到/usr/local/etc/php-fpm.d/目录下，将www.conf.default拷贝一份成www.conf

   root@iZ25fm7iewtZ:/usr/local/etc# cd php-fpm.d/
   root@iZ25fm7iewtZ:/usr/local/etc/php-fpm.d# cp www.conf.default www.conf

   编辑www.conf文件，将user和group改成和nginx.conf中的user和group一致

   user = www
   group = www

   再次启动

   /usr/local/sbin/php-fpm

   查看是否启动成功

   root@iZ25fm7iewtZ:/usr/local/etc# ps -ef | grep php-fpm
   root      3691     1  0 18:49 ?        00:00:00 php-fpm: master process (/usr/local/etc/php-fpm.conf)
   www-data  3692  3691  0 18:49 ?        00:00:00 php-fpm: pool www
   www-data  3693  3691  0 18:49 ?        00:00:00 php-fpm: pool www
   root      4982 29553  0 18:59 pts/1    00:00:00 grep --color=auto php-fpm
   
   root@iZ25fm7iewtZ:/usr/local/etc# netstat -tnl | grep 9000
   tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN  

   开机启动php-fpm，开机启动的配置文件是：/etc/rc.local ，加入 /usr/local/sbin/php-fpm 即可

   vi /etc/rc.local
   添加 /usr/local/sbin/php-fpm 

   修改nginx的配置文件，支持php文件的解析，找到location的添加位置，在后面添加下面这个location

    location ~ \.php$ {
                           root /var/www; #指定php的根目录
                           fastcgi_pass 127.0.0.1:9000;#php-fpm的默认端口是9000
                           fastcgi_index index.php;
                           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                           include fastcgi_params;
                   }

   测试nginx.conf是否修改成功

   /usr/sbin/nginx -t

   重起nginx

   /usr/sbin/nginx -s reload

   进入到/var/www目录(如果该目录不存在的话，就使用mkdir命令创建)

   vi index.php
   
   添加
   
   <?php phpinfo(); ?>

   最后在浏览器中输入:localhost/index.php即可
