Using version ^1.5 for swow/swow然后運行 vendor/bin 目錄下的自動安裝器 swow-builder 即可開始安裝：
./vendor/bin/swow-builder安裝日志
# ./vendor/bin/swow-builder
> cd /var/www/webman2024/vendor/swow/swow/ext && \
phpize && \
./configure
Configuring for:
PHP Api Version: 20230831

開啟swow事件驅動
在webman框架中開啟swow事件驅動特別簡單，只有配置一下就可以了。
修改配置文件config/server.php服務配置文件
return [
'listen' => 'http://0.0.0.0:8787',
'transport' => 'tcp',
'context' => [],
'name' => 'webman',
'count' => cpu_count() * 10,
'user' => '',
'group' => '',
'reusePort' => false,
'event_loop' => \Workerman\Events\Swow::class,
'stop_timeout' => 2,
'pid_file' => runtime_path() . '/webman.pid',
'status_file' => runtime_path() . '/webman.status',
'stdout_file' => runtime_path() . '/logs/stdout.log',
'log_file' => runtime_path() . '/logs/workerman.log',
'max_package_size' => 10 * 1024 * 1024
];啟動webman，查看事件驅動是否已經是swow事件驅動。使用以下命令啟動
php -d extension=swow webman start終端展示
/var/www/webman2024 # php -d extension=swow webman start
Workerman[webman] start in USER mode

協程
協程，英文Coroutines，是一種比線程更加輕量級的存在。最重要的是，協程不是被操作系統內核所管理，而完全是由程序所控制（也就是在用戶態執行）。
