php扩展模块安装

• PHP一旦编译完成后，要想再增加一个功能模块的话，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。

• 查看PHP都加载的功能模块

• 以扩展模块的形式编译安装一个PHP的redis模块

[root@minglinux-01 /usr/local/src] wget https://codeload.github.com/phpredis/phpredis/zip/develop 
[root@minglinux-01 /usr/local/src] mv develop phpredis-develop.zip
[root@minglinux-01 /usr/local/src] unzip phpredis-develop.zip 
[root@minglinux-01 /usr/local/src] cd phpredis-develop/
[root@minglinux-01 /usr/local/src/phpredis-develop] /usr/local/php/bin/phpize  //目的是生成configure文件，没有就无法编译

Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
//报错缺少autoconf包，所以先安装该包再生成一次

[root@minglinux-01 /usr/local/src/phpredis-develop] yum install -y autoconf
[root@minglinux-01 /usr/local/src/phpredis-develop]  /usr/local/php/bin/phpize   //再执行一次

[root@minglinux-01 /usr/local/src/phpredis-develop] /usr/local/php7/bin/php -m|grep redis    //未加载redis模块
-bash: /usr/local/php/bin/php: 没有那个文件或目录

[root@minglinux-01 /usr/local/src/phpredis-develop] vim /usr/local/php/etc/php.ini    
extension = redis.so    //在php.in中添加这一行

[root@minglinux-01 /usr/local/src/phpredis-develop] /usr/local/php/bin/php -m|grep redis
PHP Deprecated:  Comments starting with '#' are deprecated in /usr/local/php/etc/php.ini on line 450 in Unknown on line 0
redis     //已经加载了redis模块

redis等模块不是php自带，使用时需要专门下载。在php源码包中的ext目录下有很多模块，该目录下的模块安装配置不需要下载，只要进入对应包的目录，执行/usr/local/php/bin/phpize在该目录下生成configure文件，然后生成可编译文件，编译、安装即可。生成可编译文件（即执行./configure）时需要跟参数--with-php-config=/usr/local/php/bin/php-config。
