Ubuntu 18.04。
我有一个谜。当我访问 localhost:8787 时，我被带到 rstudio 登录屏幕：
我不知道在 localhost:8787 托管 rstudio 应用程序的进程是什么。几周前，我确实为通过 localhost:8787 访问的 rstudio 运行了一个 docker 容器。但是，该容器已被停止、删除，事实上，我已经删除了所有 docker 镜像：
（这里没有容器）
docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
甚至没有要运行的图像：
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
在搜索“如何判断本地主机上托管的进程”后，我发现了一篇帖子。我不确定在这里使用什么搜索词。
经过一番搜索，我在终端中运行了这个命令：
netstat -aon | grep 8787
哪个返回了这个：
netstat -aon | grep 8787

这里发生了什么事？！为什么 localhost:8787 服务于 rstudio 应用程序，我该如何阻止它？
编辑：每条评论的输出dpkg -l | grep rstudio和下方：systemctl list-units --type service | grep -i rstudio
dpkg -l | grep rstudio
ii rstudio 1.3.1093 amd64 RStudio
ii rstudio-server 1.3.1093 amd64 RStudio Server
和
systemctl list-units --type service | grep -i rstudio
rstudio-server.service loaded active running RStudio Server
如果您想暂时禁用RStudio Server，请通过以下方式禁用其服务
如果要完全删除 RStudio Server，请使用以下命令将其卸载
