PHP Expansion Module Installation

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加载的模块[[email protected] ~]# /usr/local/php/bin/php -m[PHP Modules]bz2CorectypedatedomeregexiffileinfofiltergdhashiconvjsonlibxmlmbstringmcryptmysqlmysqliopensslpcrePDOpdo_mysqlpdo_sqlitePharposixReflectionsessionSimpleXMLsoapsocketsSPLsqlite3standardtokenizerxmlxmlreaderxmlwriterzlib[Zend Modules]

2. Install a PHP extension Module (Redis module)

3. Modify the PHP configuration file to make the extension effective

[```
[Email protected] phpredis-develop]# Vim/usr/local/php/etc/php.ini//Add the following

Extension = redis.so

[Email protected] phpredis-develop]#/usr/local/php/bin/php-m | grep Redis//See if Redis is loaded
Redis
