PHP擴展模塊安裝

PHP擴展模塊安裝

編譯httpd時，有涉及動態和靜態模塊，PHP也一樣有靜態與動態之分，之前所涉及到的PHP安裝都全部爲靜態，並沒有任何動態的模塊，所謂動態，就是一個獨立存在的.so文件，在httpd中PHP就是以動態模塊的形式被加載的。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展模塊（生成一個.so文件），然後在php.ini中配置一下，就可以被加載使用了。

1.查看PHP加載了哪些模塊

2.安裝一個PHP的redis擴展模塊。

[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

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/php -m |grep redis

[root@gary-tao phpredis-develop]# /usr/local/php/bin/php -i |grep extension_dir  //查看擴展模塊存放目錄，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（可以放到文件最後一行）

定義如下：

extension = redis.so

[root@gary-tao phpredis-develop]# /usr/local/php7/bin/php -m |grep redis

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裏設置一下timezone那個參數

舉例：

你想編譯一個擴展模塊的時候，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，下面是給大家舉例一個zip模塊實驗操作如下：
