RStudio 服务器无法连接到服务

Question

当我尝试登录服务器时，我顺利通过了用户名和密码屏幕（它拒绝错误的 username/password 组合，并接受正确的组合）。但是，一旦我输入我的用户名和密码，它就会停顿片刻，并显示一条消息，显示无法连接到服务。

错误日志为：

Sep 24 12:22:41 ABRILPREDSVR1 kernel: [1495156.302209] ip6_tables: (C) 2000-2006 Netfilter Core Team
Sep 24 12:22:50 ABRILPREDSVR1 rserver[21509]: ERROR system error 2 (No such file or directory) [child-path=/usr/lib/rstudio-server/bin/rsession]; OCCURRED AT: rstudio::core::Error rstudio::core::system::launchChildProcess(std::string, std::string, rstudio::core::system::ProcessConfig, rstudio::core::system::ProcessConfigFilter, PidType*) /home/ubuntu/rstudio/src/cpp/core/system/PosixSystem.cpp:1433; LOGGED FROM: rstudio::core::Error rstudio::core::system::launchChildProcess(std::string, std::string, rstudio::core::system::ProcessConfig, rstudio::core::system::ProcessConfigFilter, PidType*) /home/ubuntu/rstudio/src/cpp/core/system/PosixSystem.cpp:1435

我不小心删除了 rsession 文件。现在做什么

同样当我运行sudo rstudio-server verify-installation它返回错误。

同时运行这个 sudo rstudio-server status 我得到这个

Rstudio 服务器昨天还在工作，之后我不小心删除了 /usr/lib/rstudio-server/bin/ 上的 rsession 文件，今天我尝试在浏览器上加载 rstudio 服务器，但出现错误。

Answer 1

我从 ubuntu 16.04 服务器卸载了 R 和其他相关组件，然后重新安装。
