问题[unix-sockets](server)

要在 Ubuntu 上测试 memcached，我会运行以下命令：

echo "stats settings" | nc -U /run/mydir/memcached.sock

不过现在我换成了 Debian，Debiannc不支持这个-U选项。

我试过了ss，没有喜悦。listentelnet -b /run/mydir/memcached.sock

Debian 中的等效命令是什么？

我目前正在我的 Nginx Web 服务器中监听 TCP 套接字，但由于某些原因，我想监听我的 UNIX 域套接字。问题是我无法php8.0-fpm.sock在/var/run/php/php8.0-fpm.sock和/run/php/php8.0-fpm.sock路径中找到。当我运行时ls /run/php，它只显示php8.0-fpm.pid。

systemctl status php8.0-fpm确认它已正确安装并运行：
