安装PHP：5.6 （源码包方式）

cd /usr/local/src

wget http://

tar zxvf php-5.6.32.tar.gz

cd php-5.6.32

#先确保已安装：openssl-devel；libxml2-devel；bzip2-devel；libjpeg-turbo-devel；libpng-devel；freetype-devel；epel-release；php-mcrypt；libmcrypt-devel     这几个包 

注意：安装php7时，不用添加--with-mysql=/usr/local/mysql/；其他不变 

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/httpd/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql/ --with-pdo-mysql=/usr/local/mysql/ --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir -with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
