这个是Zend官方的介绍：http://php7.zend.com/install-ubuntu.php
首先安装依赖：
apt-get update && apt-get install -y \
libcurl4-openssl-dev \
libmcrypt-dev \
libxml2-dev \
libjpeg-dev \
libfreetype6-dev \
libmysqlclient-dev \
libt1-dev \
libgmp-dev \
libpspell-dev \
libicu-dev \
librecode-dev \
libxpm4
解压，然后进行configure
./configure --prefix=/usr/local/php7 \
--with-config-file-path=/usr/local/php7/etc \
--with-mcrypt=/usr/include \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gd \
--with-iconv \
--with-zlib \
--enable-xml \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--enable-ftp \
--enable-gd-native-ttf \
--with-openssl \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--without-pear \
--with-gettext \

随后开始进行make && make install
突然出现编译错误

开始安装 libiconv (字符编码转换库)
网站地址: http://www.gnu.org/software/libiconv/
当前版本: http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
$ wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
$ tar zxf libiconv-1.14.tar.gz
$ cd libiconv-1.14
$ ./configure --prefix=/usr/local/lib/libiconv
$ make && make install
出现
./stdio.h:1010:1: error: 'gets' undeclared here (not in a function)
解决:
修改srclib/stdio.in.h 第695行
如下:
//_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#if defined(__GLIBC__) && !defined(__UCLIBC__) && !__GLIBC_PREREQ(2, 16)
_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
#endif
顺利编译通过libiconv
然后重新configure PHP7
./configure --prefix=/usr/local/php7 \
--with-config-file-path=/usr/local/php7/etc \
--with-iconv=/usr/local/lib/libiconv \
--with-mcrypt=/usr/include \
--with-mysql=mysqlnd \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd \
--with-gd \
--with-iconv \
--with-zlib \
--enable-xml \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--enable-ftp \
--enable-gd-native-ttf \
--with-openssl \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--without-pear \
--with-gettext \
--enable-session \
--with-curl \
--with-jpeg-dir \
--with-freetype-dir \
--enable-opcache
在Makeile的104行，加上：
EXTRA_LIBS = -lcrypt -lz -lresolv -lcrypt -lrt -lmcrypt -lltdl -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lxml2 -lssl -lcrypto -lcurl -lxml2 -lssl -lcrypto -lfreetype -lz -lpng12 -lxml2 -lxml2 -lcrypt -lxml2 -lxml2 -lxml2 -lxml2 -lssl -lcrypto -lcrypt -liconv
编译完成：

PHP7的压力测试：
同样的业务处理，PHP的性能几乎提高了一倍，看来PHP7在性能方面确实下了不少功夫，大大值得期待啊！
