通过 PECL 安装 PHP 扩展（以 CentOS7 中安装 swoole 为例）
<p>原文地址：https://blog.csdn.net/kikajack/article/details/82495190</p><p>常用工具<br>PECL 和 phpize<br>官网文档</p>
<p>PHP 有大量的扩展可以使用，比如用于连接数据库的扩展 mysqli，图形库 gd2 等。扩展有两种安装方法：</p>
<p>通过 pear install xxx 安装，需要提前在机器上安装 pear，CentOS 下可以通过 yum install php72w-pear 可以安装 PHP7.2 对应的版本<br>用 phpize 源码编译安装，CentOS 下可以通过 yum install php72w-devel 可以安装 PHP7.2 对应的版本<br>注意安装的扩展需要和 PHP 的版本匹配。例如我安装的是 PHP7.2，则需要安装 PHP7.2 对应的 php-devel 和 php-pear：</p>

<p>pecl<br>官网文档</p>
<p>pecl install extname 命令自动下载源码、编译代码，并将编译后的 extname.so 安装到 extension_dir 中。然后编辑 php.ini 引入 extname.so 就可以加载了。</p>
<p>phpize<br>使用 pecl 需要提前将扩展库发布到 PECL 官方仓库中。而源码安装更灵活。</p>
<p>phpize 的通用流程：</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 0, 1)">$ cd extname
$ phpize
