安装PHP5
PHP官网
www.php.net
当前主流版本为5.6/7.1
新机器安装php会缺很多依赖的包，报错缺包的提醒可能达10次，所以要有耐心看，没个报缺对应1-2个包，下面举几个例子：
1）configure: error: Cannot find OpenSSL's <evp.h>
yum install -y openssl openssl-devel
2）configure: error: Please reinstall the BZip2 distribution
yum install -y bzip2 bzip2-devel
3）configure: error: jpeglib.h not found.
yum -y install libjpeg-devel
4）configure: error: png.h not found.
yum install -y libpng libpng-devel
5）configure: error: freetype-config not found.
yum install -y freetype freetype-devel

两个php可以同时存在，但需要指定httpd调用的模块，在httpd的配置文件/usr/local/apache2.4/conf/
httpd.conf里，注释掉其中一个：
LoadModule php5_module
LoadModule php7_module
不然会报错如下：
#/usr/local/apache2.4/bin/apachectl start
/usr/local/apache2.4/bin/apachectl: line 79: 23642 Segmentation fault $HTTPD -k $ARGV
