配置Nginx來支持php

1. 安裝php7     
   下載地址：https://secure.php.net/downloads.php
   這裏下載的是：wget http://ar2.php.net/distributions/php-7.0.6.tar.gz
   下載以後解壓並進入在解壓文件中
   安裝：./configure  –enable-fpm (enable-fpm參數便可開啓PHP-FPM)  ->  make && make install
   (PHP在 5.3.3 以後已經講php-fpm寫入php源碼核心了)
   默認安裝目錄:
   

   root@iZ25fm7iewtZ:/php-7.0.6# make install
   Installing shared extensions:     /usr/local/lib/php/extensions/no-debug-non-zts-20151012/
   Installing PHP CLI binary:        /usr/local/bin/
   Installing PHP CLI man page:      /usr/local/php/man/man1/

   Installing build environment:     /usr/local/lib/php/build/
   Installing header files:           /usr/local/include/php/
   Installing helper programs:       /usr/local/bin/
     program: phpize
     program: php-config
   Installing man pages:             /usr/local/php/man/man1/
     page: phpize.1

   [PEAR] PEAR           - already installed: 1.10.1
   Wrote PEAR system config file at: /usr/local/etc/pear.conf
   You may want to add: /usr/local/lib/php to your php.ini include_path
   /php-7.0.6/build/shtool install -c ext/phar/phar.phar /usr/local/bin
   ln -s -f phar.phar /usr/local/bin/phar
   Installing PDO headers:           /usr/local/include/php/ext/pdo/

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

   報錯
   [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/目錄下，將php-fpm.conf.default拷貝一份成php-fpm.conf

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

   而後在編輯php-fpm.conf配置文件

   ;最後一行改爲以下
   include=/usr/local/etc/php-fpm.d/*.conf

   進入到/usr/local/etc/php-fpm.d/目錄下，將www.conf.default拷貝一份成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

   編輯www.conf文件，將user和group改爲和nginx.conf中的user和group一致

   user = www
   group = www

   再次啓動

   /usr/local/sbin/php-fpm

   查看是否啓動成功
   

   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  

   開機啓動php-fpm，開機啓動的配置文件是：/etc/rc.local ，加入 /usr/local/sbin/php-fpm 便可

   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，在後面添加下面這個location

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

   測試nginx.conf是否修改爲功

   /usr/sbin/nginx -t

   重起nginx

   /usr/sbin/nginx -s reload

   進入到/var/www目錄(若是該目錄不存在的話，就使用mkdir命令建立)

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

   最後在瀏覽器中輸入:localhost/index.php便可
