[Help] portal-web: 用户新建桌面连接失败 #1376

Closed zhengkang2020 closed 1 month ago

发生了什么 | What happened

其他用户使用正常，只有用户A新建桌面失败，偶尔会有提示"无法以用户身份连接到登录节点。请确认您的家目录的权限为700、750或者755" ，但是检查和其他用户的权限是一样的。

可以尝试删除 用户家目录/scow/desktops/desktops.json 文件再看看能否正常创建。此外可以提供 portal-server 日志方便排查问题

问题依旧，下面是日志：

scow 节点能访问到 192.168.55.83:5901 吗？

zhengkang2020 commented 1 month ago

目前内网测试环境，防火墙关闭，正常连接192.168.55.83:5901

如果只有单个用户有问题的话，请去该用户的文件夹下查看他是否安装了其它软件，或者修改了某些环境变量，可能与此有关

zhengkang2020 commented 1 month ago

问题已经解决，经确认是用户环境变量 .bashrc文件最后多了一行 export DISPLAY=:11.0 ，以下是具体步骤：

## 1、修改用户环境变量，用户自己操作
cd && cp .bashrc .bashrc.bak && sed -i '/^export DISPLAY=:11.0/s/^/#/' ~/.bashrc && source .bashrc
## 2、root权限登陆"登陆节点"，注销用户会话，然后用户重新测试
pkill -u xxxx
