说在前面：
本人系统ubuntu12.04 64位，先前编译安装有php5.5.7版本，现在为了满足composer对php的版本要求特尝试安装php7,使用的用户为www先前已经添加。
安装依赖库：
apt-get install libxml2-dev openssl libjpeg-dev libpng-dev libcurl3-openssl-dev libfreetype6-dev libxslt-dev
指定下载目录并下载源码：
cd /tmp wget http://cn2.PHP.net/distributions/php-7.0.5.tar.gz #http://cn.php.net/distributions/php-7.0.18.tar.gz
解压进入目录：
tar zxvf php-7.0.5.tar.gz cd php-php-7.0.5 mkdir -p /alidata/server/php-7.0.5 ln -s /alidata/server/php-7.0.5 /alidata/server/php70
mkdir -p /alidata/log/php70
touch /alidata/log/php70/php-fpm.log
编译:
#防止网络中断带来不必要的麻烦可以使用screen命令多重视窗管理程序 screen -S installphp7 #如果网络中断可用screen -r installphp7恢复现场，exit直接退出screen作业 #显示目前所有的screen作业 screen -ls
./configure --prefix=/alidata/server/php70 --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-xmlrpc --with-xsl --with-zlib --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-xml --enable-zip
安装，短则几分钟长则几十分钟视机器速度而定：
make make install
复制配置文件：
