linux实践——编译安装PHP7

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-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

安装，短则几分钟长则几十分钟视机器速度而定：

make
make install
