ubuntu18.04 Rstudio-server无法连接服务器

Posted 2023-04-05

参考技术A 无法连接服务器有以下几个原因：

没有配置文件

防火墙8787端口没有打开

Linux下登陆账户没有home文件夹，比如test1账户应该有/home/test1/文件夹

R版本和Rstudio或者Rstudio-server版本不一致。例如R为i386-版本，Rstudio/Rstudio-server为amd64版本，Rstudio-server在启动后，虽然可以通过8787端口登陆，输入账户和用户名，但是无法连接服务器，可以通过卸载i386版本，再安装amd64版本的R基础包。重新启动Rstudio-server即可

ps:可以尝试运行/usr/lib/rstudio-server/bin/rsession或者rsever，看下报错信息

E: 有一些索引文件不能下载，它们可能被忽略了，也可能转而使用了旧的索引文件。
OK了！！我修改了源，让它选择最佳下载服务器。我的是：http://ubuntu.srt.cn/ubuntu本回答被提问者采纳 参考技术B 首先你要判断你的计算机是否接入网络。能否打开例如www.baidu.com的网站。
如果不能上网当然就会出现“检测internet连接”的提示。
如果连不上网，什么都下载不下来再怎么更新也都是无效的。
所谓的500错误是不可恢复的网络连接。楼主还是先检查看看计算机是不是能上网再说吧。
如果能上网，那就到网上搜索 ubuntu 10.10 更新源 的关键词。网上有大量的更新教材可查。 参考技术C 源的问题，换个源吧，最好是用台湾源，比其它的源要快要新，而且速度也很快，一般我选台湾源里的前三个，速度都不错。 参考技术D 换个源试试
