PHP擴充子產品安裝
編譯httpd時，有涉及動态和靜态子產品，PHP也一樣有靜态與動态之分，之前所涉及到的PHP安裝都全部為靜态，并沒有任何動态的子產品，所謂動态，就是一個獨立存在的.so檔案，在httpd中PHP就是以動态子產品的形式被加載的。PHP一旦編譯完成後，要想再增加一個功能的話，要麼重新編譯PHP，要麼直接編譯一個擴充子產品（生成一個.so檔案），然後在php.ini中配置一下，就可以被加載使用了。
1.檢視PHP加載了哪些子產品
[root@gary-tao ~]# /usr/local/php/bin/php -m

2.安裝一個PHP的redis擴充子產品。
[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 phpredis-develop]# /usr/local/php7/bin/phpize //生成configure檔案
Configuring for:
PHP Api Version: 20160303
Zend Module Api No: 20160303
Zend Extension Api No: 320160303
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
[root@gary-tao phpredis-develop]# yum install -y autoconf
[root@gary-tao phpredis-develop]# /usr/local/php7/bin/phpize
[root@gary-tao phpredis-develop]# ls

[root@gary-tao phpredis-develop]# ./configure --with-php-config=/usr/local/php7/bin/php-config
[root@gary-tao phpredis-develop]# echo $?
[root@gary-tao phpredis-develop]# make
[root@gary-tao phpredis-develop]# make install
Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
[root@gary-tao phpredis-develop]# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.so redis.so
[root@gary-tao phpredis-develop]# /usr/local/php7/bin/php -m
[root@gary-tao phpredis-develop]# /usr/local/php7/bin/php -m |grep redis
[root@gary-tao phpredis-develop]# /usr/local/php/bin/php -i |grep extension_dir //檢視擴充子產品存放目錄，我們可以在php.ini中去自定義該路徑
PHP Warning: Unknown: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in Unknown on line 0
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
[root@gary-tao phpredis-develop]# vim /usr/local/php7/etc/php.ini //增加一行配置（可以放到檔案最後一行）
定義如下：
extension = redis.so
redis
增加示例圖：
報錯：
缺少autoconf包，安裝yum install -y autoconf
這個不影響使用，如果要去掉它，可以在php.ini裡設定一下timezone那個參數
舉例：
你想編譯一個擴充子產品的時候，如果它自帶的源碼包ext下有這個目錄，那就可以直接在目錄下編譯它，如果沒有那就需要去官網下載下傳，下面是給大家舉例一個zip子產品實驗操作如下：
