centos6.5编译安装php7，及配置与nginx通信。

一、配置编译环境

yum update && yum upgrade
yum groupinstall "Development Tools"
yum install gcc gcc-c++ pcre* openssl* gd-devel* zlib-devel pcre-devel libxml2-devel curl-devel

二、下载安装libmcrypt(yum包中没有libmcrypt依赖包，所以需要单独编译安装)

wget https://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz
tar -zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure
make && make install

编辑  /etc/ld.so.conf  末行添加 /usr/local/lib 并执行：ldconfig

三、下载php7压缩包

wget http://cn2.php.net/distributions/php-7.0.1.tar.gz
tar zxvf php-7.0.1.tar.gz

四、编译配置

./configure 
--prefix=/usr/local/php7   [php安装路径]
--exec-prefix=/usr/local/php7 
--bindir=/usr/local/php7/bin 
--sbindir=/usr/local/php7/sbin 
--includedir=/usr/local/php7/include 
--libdir=/usr/local/php7/lib/php 
--mandir=/usr/local/php7/php/man 
--with-config-file-path=/usr/local/php7/etc 
--with-mcrypt=/usr/include 
--with-mhash 
--with-openssl 
--with-mysqli=shared,mysqlnd 
--with-pdo-mysql=shared,mysqlnd 
--with-gd 
--with-iconv 
--with-zlib 
--enable-zip 
--enable-inline-optimization 
--disable-debug 
--disable-rpath 
--enable-shared 
--enable-xml 
--enable-bcmath 
--enable-shmop 
--enable-sysvsem 
--enable-mbregex 
--enable-mbstring 
--enable-ftp 
--enable-gd-native-ttf 
--enable-pcntl 
--enable-sockets 
--with-xmlrpc 
--enable-soap 
--without-pear 
--with-gettext 
--enable-session 
--with-curl 
--with-jpeg-dir 
--with-freetype-dir 
--enable-opcache 
--enable-fpm 
--without-gdbm 
--disable-fileinfo

配置成功

五、安装编译

make && make install

六、配置文件

cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

七、启动php-fpm

/usr/local/php7/sbin/php-fpm

八、配置nginx.conf与php-fpm通信（nginx的编译安装：http://www.cnblogs.com/yxhblogs/p/7489925.html）

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ .php$ {
　　root html;//web根目录
　　fastcgi_pass 127.0.0.1:9000;
　　fastcgi_index index.php;
　　fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;//注意该行配置
　　include fastcgi_params;
}

九、创建php测试文件

在/usr/local/nginx/html下创建phpinfo.php文件
