首先下載php-5.6.39安裝包
http://www.php.net/downloads.php
先通過yum安裝部分插件，否則configure時會報錯，可以先configure，根據報錯內容yum對應，其中mcrypt無法yum安裝
yum install -y libcurl libvpx-devel libjpeg-devel libpng-devel openssl
openssl-devel gmp-devel libmcrypy readline readline-devel libxslt
libxslt-devel freetype freetype-devel
解壓tar包，並進入
./configure \

--with-zlib=/usr \
--with-bz2=/usr \
--with-recode=/usr \
--with-ldap \
--with-pear \
--with-readline \
--with-apxs2=/usr/sbin/apxs
--enable表示不需要第三方庫直接啓用，--with表示要使用第三方擴展庫
--with-apxs2=/usr/sbin/apxs 用於生成libphp5.so模塊，在httpd中引入該模塊，才能訪問php
成功之後再make && make install
