方法2

自动移除全部不使用的软件包

sudo apt-get autoremove

列出与nginx相关的软件，并依次删除显示的软件，这个方法更加通用，我照猫画虎使用在php上面，也非常靠谱（php8.0-fpm）

dpkg --get-selections|grep nginx
sudo apt-get --purge remove nginx
sudo apt-get --purge remove nginx-common
sudo apt-get --purge remove nginx-cor

使用ps命令查看相关进程,-A显示有限信息，-l显示详细信息 -e显示所有进程，aux显示系统所有进程

ps -le ｜ grep nginx
