1、下载swoole最新源码（以swoole4.4.14为例）后解压至任意目录，并进入其中：

  1. cd swoole-src-4.4.14

2、使用phpize生成configure文件

（phpize编译PHP扩展的工具，主要是根据系统信息生成对应的configure文件，详情请参考官方文档：https://www.php.net/manual/en/install.pecl.phpize.php）。

不确定phpize的位置可以先查找一下即可:

  1. xiongxudeMacBook-Pro:swoole-src-4.4.14 xmsite$ find / -name phpize
  2. /usr/bin/phpize

执行/usr/bin/phpize后结果如下：

  1. xiongxudeMacBook-Pro:swoole-src-4.4.14 xmsite$ /usr/bin/phpize
  2. grep: /usr/include/php/main/php.h: No such file or directory
  3. grep: /usr/include/php/Zend/zend_modules.h: No such file or directory
  4. grep: /usr/include/php/Zend/zend_extensions.h: No such file or directory
  5. Configuring for:
  6. PHP Api Version:        
  7. Zend Module Api No:     
  8. Zend Extension Api No:

3、配置编译信息

先确定php-config的位置，我的机器上是：/usr/local/bin/php-config

  1. cent os
  3. ./configure --with-php-config=/usr/local/bin/php-config --enable-http2 --enable-swoole-json  --enable-swoole-curl --enable-openssl 
  5. mac os 中指定openssl路径
  7. ./configure --with-php-config=/usr/local/bin/php-config  --enable-http2 --enable-swoole-json  --enable-swoole-curl --enable-openssl --with-openssl-dir=/usr/local/Cellar/openssl@1.1/1.1.1h

4、编译并安装

  1. make && make install

大功告成！

通过php --ri swoole查看下swoole的版本

  1. xiongxudeMacBook-Pro:swoole-src-4.4.14 xmsite$ php --ri swoole
