修改rsession.conf配置文件后，无法登陆Rstudio|修改rsession.conf配置文件后，无法登陆Rstudio server解决办法修改rsession.conf配置文件后，无

写在前面问题经常有，今年特别多。
也不知道是不是因为centos系统的原因，为啥明明我还在跑着程序，2个小时后，RStudio server自动退出登陆界面了。于是通过查询得知，可以通过修改/etc/rstudio/rsession.conf文件，让用户session 将不会suspend，一直运行。
正文修改rsession.conf文件

vim /etc/rstudio/rsession.conf 添加session-timeout-minutes=0#会话超时时间

接着我尝试重启Rstudio server让其生效

rstudio-server restart #重启

后来就遇到了发现登不进Rstudio server了，但是xshell均正常。
检查Rstudio server 状态

【修改rsession.conf配置文件后，无法登陆Rstudio|修改rsession.conf配置文件后，无法登陆Rstudio server解决办法】去google了比较多帖子，都没有找到一个合适的办法，最终在Stack Overflow里面找到解决办法
原因解析

The reason why you can not restart rstudio-server is that the PORT 8787 was been using by previous rserver. After knowing this, the solution is easy. First, check the pid that was using PORT 8787

简单来说就是原8787端口被其他资源占用了，把占用的程序kill掉就解决了
解决办法

#查看占用端口 sudo netstat -anp | grep 8787 # tcp00 0.0.0.0:87870.0.0.0:*LISTENpid/rserver#Second, kill this pid (use your pid) sudo kill -9 #Third, restart rstudio-server or reinstall resutio server package rstudio-server restart #重启

至此，问题解决， RStudio Server也顺利登陆。
