最近小团队需要共同完成一项数据处理的任务，我们想到了Rstudio server的协同工作。于是搭建了Centos 8 + Rstudio Server 1.3.105 + R 4.0.2的环境。

经过测试，R是可以运行的，使用网页打开http://127.0.0.1:8787也能看到登陆页面，输入用户名和密码（非root账号）后，页面开始等待，大概1min后出现错误提示：Rstudio Initialization Error: Unable to connect to service。

在网上找了许多资料，都没有解决问题。根据有为国际友人的操作，我也去跟踪了一下Rstudio的线程情况，出现最多的提示是：No such file or directory。我们尝试着解决这个问题，可是无从下手，因为之前按照网上的提示新建了相关的用户文件夹。

还请各位能出手相助，先谢啦~~

下面是线程跟踪的部分
