详解php通过pecl方式安装扩展

1、安装pecl及创建快捷键（若安装php时已带可忽略这步安装步骤）


# cd /usr/local/php/bin/  //可查看是否已带有pecl

# wget http://pear.php.net/go-pear.phar -O go-pear.php

# php go-pear.php

# ln -s /usr/local/php

/bin/pecl /usr/bin/pecl

2、查询是否已经收录了该扩展

# pecl search swoole  // swoole为要查询扩展名（以swoole扩展为例）

//查询结果：

Retrieving data...0%

.Matched packages, channel pecl.php.net:

=======================================

Package Stable/(Latest) Local

swoole 1.9.23 (stable) Event-driven asynchronous and concurrent networking engine with high performance for PHP.

swoole_serialize 0.1.1 (beta) the fastest and smallest serialize fucntion bound for php7

3、安装配置扩展

# pecl install swoole

//输出结果：

Build process completed successfully

Installing '/usr/lib64/php/modules/swoole.so'

install ok: channel://pecl.php.net/swoole-1.9.23

configuration option "php_ini" is not set to php.ini location

You should add "extension=swoole.so" to php.ini

  
# 配置php.ini引用swoole.so然后重启php即可

注：相比于phpize方式安装，pecl方式安装更为简便，可省去手动添加到php.ini的环节
