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

[Zend Modules]2、安装一个PHP扩展模块(redis模块)
[[email protected] ~]# cd /usr/local/src/
[[email protected] src]# wget https://codeload.github.com/phpredis/phpredis/zip/develop
[[email protected] src]# mv develop phpredis-develop.zip
[[email protected] src]# unzip phpredis-develop.zip
[[email protected] src]# cd phpredis-develop/
[[email protected] phpredis-develop]# /usr/local/php/bin/phpize //目的是生成configure文件
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
//报错Cannot find autoconf，需要安装一些autoconf
[[email protected] phpredis-develop]# yum install -y autoconf
[[email protected] phpredis-develop]# /usr/local/php/bin/phpize
Configuring for:
PHP Api Version: 20131106
Zend Module Api No: 20131226
Zend Extension Api No: 220131226
[[email protected] phpredis-develop]# ./configure --with-php-config=/usr/local/php/bin/php-config
[[email protected] phpredis-develop]# make
[[email protected] phpredis-develop]# make install
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
//make install会把编译好的redis放到这个目录下，该目录为扩展模块存放目录
[[email protected] phpredis-develop]# /usr/local/php/bin/php -i | grep -i extension_dir
extension_dir => /usr/local/php/lib/php/extensions/no-debug-zts-20131226 => /usr/local/php/lib/php/extensions/no-debug-zts-20131226
sqlite3.extension_dir => no value => no value
//查看扩展模块目录，也可以在php.ini中修改目录
[[email protected] phpredis-develop]# ls /usr/local/php/lib/php/extensions/no-debug-zts-20131226/
opcache.so redis.so3、修改PHP配置文件，使扩展模块生效
[```
[email protected] phpredis-develop]# vim /usr/local/php/etc/php.ini //添加以下内容
extension = redis.so
[[email protected] phpredis-develop]# /usr/local/php/bin/php -m | grep redis //查看是否加载了redis
redis
