Ubuntu 18.04。
我有一个谜。当我访问 localhost:8787 时，我被带到了 rstudio 登录屏幕：
我不知道在 localhost:8787 上托管 rstudio 应用程序的进程是什么。几周前，我确实为 rstudio 运行了一个通过 localhost:8787 访问的 docker 容器。然而，该容器已被停止、删除，事实上，我已删除所有 docker 镜像：
（此处无容器）
docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
甚至没有任何可运行的图像：
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
在搜索“如何判断本地主机上托管了哪些进程”后，我找到了一篇帖子。我不确定在这里要使用什么搜索词。
经过一些搜索，我在终端中运行了这个命令：
netstat -aon | grep 8787
返回的是：
netstat -aon | grep 8787

这里发生了什么？！为什么 localhost:8787 提供 rstudio 应用程序？我该如何停止它？
dpkg -l | grep rstudio编辑：以下每个评论的输出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
答案1
如果你想禁用RStudio 服务器然后暂时禁用其服务
sudo systemctl disable rstudio-server.service
如果要完全删除 RStudio Server，请使用以下命令卸载它
sudo apt-get purge rstudio-server
