make && make install

yum install libxml2-devel -y
yum install libcurl-devel -y
yum install libjpeg-devel -y
yum install libpng-devel -y
yum install freetype-devel -y

yum install libmcrypt* -y
libmcrypt明明已经安装但缺少devel包，centos自带yum和163yum都没有对应包(libmcrypt-devel)下载，epel可以很好的解决这一难题，参考链接： http://www.cnblogs.com/SunnyZhu/p/5420549.html  http://www.linuxidc.com/Linux/2015-08/121079.htm
yum install epel-release -y    #除了rpm安装，也可yum安装epel
yum install libmctypt-devel -y

yum install openldap openldap-devel -y
cp -frp /usr/lib64/libldap* /usr/lib/

cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

vi php-fpm.conf

;listen = 127.0.0.1:9000
listen = /tmp/php-cgi.sock   #以socke的方式访问.注视掉.ip端口的方式.

; Default Value: log/php-fpm.log
error_log = /data/php_log/php.error  #根据不同的项目名.定义不同的.sock 和日志.

# 调整进程数量
pm.max_children：p静态方式下开启的php-fpm进程数量。
pm.start_servers：动态方式下的起始php-fpm进程数量。
pm.min_spare_servers：动态方式下的最小php-fpm进程数量。
pm.max_spare_servers：动态方式下的最大php-fpm进程数量。

mkdir /data/php_log

尝试访问php页面出错，查看错误日志：
var/log/nginx/error.log报错：
2017/08/04 04:55:58 [crit] 61807#61807: *6 connect() to unix:/tmp/php-cgi.sock failed (13: Permission denied) while connecting to upstream, client: 192.168.119.129, server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-cgi.sock:", host: "192.168.119.130"

ll /tmp/php-cgi.sock发现属主属组都为root用户，因此错误原因就是：nginx的deamon用户无权限调用该socket与php-fpm通信

user = deamon
group = deamon

listen.owner = deamon
listen.group = deamon

       location ~ .php$ {
            root           /www;
            fastcgi_pass   unix:/tmp/php-cgi.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }
