PHP扩展模块安装
编译httpd时，有涉及动态和静态模块，PHP也一样有静态与动态之分，之前所涉及到的PHP安装都全部为静态，并没有任何动态的模块，所谓动态，就是一个独立存在的.so文件，在httpd中PHP就是以动态模块的形式被加载的。PHP一旦编译完成后，要想再增加一个功能的话，要么重新编译PHP，要么直接编译一个扩展模块（生成一个.so文件），然后在php.ini中配置一下，就可以被加载使用了。
1.查看PHP加载了哪些模块
[root@gary-tao ~]# /usr/local/php/bin/php -m [PHP Modules] bz2 Core ctype date dom ereg exif fileinfo filter gd hash iconv json libxml mbstring mcrypt mysql mysqli openssl pcre PDO pdo_mysql pdo_sqlite Phar posix Reflection session SimpleXML soap sockets SPL sqlite3 standard tokenizer xml xmlreader xmlwriter zlib [Zend Modules]
2.安装一个PHP的redis扩展模块。
[root@gary-tao ~]# cd /usr/local/src/ [root@gary-tao src]# wget https://codeload.github.com/phpredis/phpredis/zip/develop [root@gary-tao src]# mv develop phpredis-develop.zip [root@gary-tao src]# unzip phpredis-develop.zip //yum install -y unzip [root@gary-tao src]# cd phpredis-develop [root@gary-tao phpredis-develop]# [root@gary-tao src]# cd phpredis-develop [root@gary-tao phpredis-develop]# /usr/local/php7/bin/phpize //生成configure文件 Configuring for: PHP Api Version: 20160303 Zend Module Api No: 20160303 Zend Extension Api No: 320160303 Cannot find autoconf.

增加示例图：
报错：
缺少autoconf包，安装yum install -y autoconf
这个不影响使用，如果要去掉它，可以在php.ini里设置一下timezone那个参数
举例：
你想编译一个扩展模块的时候，如果它自带的源码包ext下有这个目录，那就可以直接在目录下编译它，如果没有那就需要去官网下载，下面是给大家举例一个zip模块实验操作如下：
