1、首先配置好编译环境
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
下载安装libmcrypt
地址：http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/
编译安装即可
tar -zxvf libmcrypt-2.5..tar.gz
cd libmcrypt-2.5.
./configure
make && make install
编辑 /etc/ld.so.conf 末行添加
/usr/local/lib
并执行：ldconfig
2、下载PHP7并解压
wget http://cn2.php.net/distributions/php-7.0.1.tar.gz
tar zxvf php-7.0..tar.gz
3、配置编译参数
./configure \
--prefix=/usr/local/php7 \
--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
