configure: error: xml2-config not found. Please check your libxml2 installation.
[root@Dasoncheng php-5.6.30]# yum install -y libxml2-devel openssl-devel bzip2-devel libjpeg-turbo-devel libpng-devel freetype-devel libmcrypt-devel
到这里2016年你会发现：libmcrypt-devel已经安装不了了，据说是因为mcrypt已经版权化了 centos就没有自带mcrypt的包了；
那么，怎么处理呢？
安装epel扩展源（主）
[root@Dasoncheng src]# yum install -y epel-release
[root@Dasoncheng src]# yum makecache
[root@Dasoncheng src]# yum install -y libmcrypt-devel
##安装epel扩展源就可以安装了！
或者，下载mcrypt源：
wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz
tar -zxvf libmcrypt-2.5.7.tar.gz
cd libmcrypt-2.5.7
mkdir -p /usr/local/libmcrytp
./configure prefix=/usr/local/libmcrytp/
make
make install
##不过，ftp的 不能保证来源的安全性；
继续编译php
[root@Dasoncheng php-5.6.30]# ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/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-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-gd-native-ttf --enable-soap --enable-mbstring --enable-sockets --enable-exif

Wrote PEAR system config file at: /usr/local/php7/etc/pear.conf
You may want to add: /usr/local/php7/lib/php to your php.ini include_path
/usr/local/src/php-7.1.6/build/shtool install -c ext/phar/phar.phar /usr/local/php7/bin
ln -s -f phar.phar /usr/local/php7/bin/phar
Installing PDO headers: /usr/local/php7/include/php/ext/pdo/

[root@Dasoncheng php-7.1.6]# cp php.ini-production /usr/local/php7/etc/php.ini
##到这里php7.的安装也就完成了！
查看php7.目录结构：
[root@Dasoncheng php-7.1.6]# ls /usr/local/apache2.4/modules/libphp7.so
/usr/local/apache2.4/modules/libphp7.so
[root@Dasoncheng php-7.1.6]# du -sh /usr/local/apache2.4/modules/libphp7.so
37M /usr/local/apache2.4/modules/libphp7.so
[root@Dasoncheng php-7.1.6]# /usr/local/apache2.4/bin/apachectl -M |grep php
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
php5_module (shared)
php7_module (shared)
那么现在问题就来了，同时安装了2个版本的php，我们怎么用呢？
##编辑httpd.conf，找到php7模块 前面加上“#”号，注释掉即可！
[root@Dasoncheng php-7.1.6]# vim /usr/local/apache2.4/conf/httpd.conf
LoadModule php5_module modules/libphp5.so
#LoadModule php7_module modules/libphp7.so
[root@Dasoncheng php-7.1.6]# /usr/local/apache2.4/bin/apachectl -M |grep php ##没有重新加载Apache配置，模块即停用了哦！
