回溯（最近一次调用）：文件 \'/usr/bin/idle\'，第 5 行，位于 \ main() 文件 \'/usr/lib/python3.10/idlelib/pyshell.py\'，第 1617 行，位于主根目录 = Tk(

Traceback (most recent call last):
  File "/usr/bin/idle", line 5, in \<module\>
    main()
  File "/usr/lib/python3.10/idlelib/pyshell.py", line 1617, in main
    root = Tk(className="Idle")
  File "/usr/lib/python3.10/tkinter/__init__.py", line 2299, in __init__
    self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

当我使用 idle 命令在 idle 中编写 python 时，我收到了此系统消息。我不知道那是什么意思。我对 ubuntu 还很陌生。我希望有人知道这个答案。

在其他应用中打开音频文件，音频确实可以播放。Visual Studio Code 只是因为某种原因不想播放音频文件。

这是 tkinter 在 Linux 上的错误。我不知道之前关于完全相同的错误消息的问题的答案是否会对您有所帮助。也许您的系统上没有加载 tcl/tk。

我是 Linux 新手，正在尝试在装有 Ubuntu 18.04.4 LTS（GNU/Linux 4.15.0-106-generic x86_64）的实例上安装 Docker。我按照此处找到的指南进行操作： https://docs.docker.com/engine/install/ubuntu/

第一步涉及运行以下一系列命令：

sudo apt-get update
sudo apt-get install ca-certificates curl

但是，当我尝试运行 sudo apt-get install ca-certificates curl 时，出现以下错误：

$ sudo apt-get install ca-certificates curl
Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 apt : Depends: adduser but it is not going to be installed
       Depends: gpgv but it is not going to be installed or
                gpgv2 but it is not going to be installed or
                gpgv1 but it is not going to be installed

       Depends: libgnutls30 (>= 3.5.6) but it is not going to be installed

 libstdc++6 : Depends: libc6 (>= 2.18) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

当我尝试按照错误提示进行操作，即运行命令 apt --fix-broken install 时，它不起作用并引发以下错误：

E: Cannot get debconf version. Is debconf installed?

我能做些什么？

我正在尝试在具有 Ubuntu 18.04.4 LTS（GNU/Linux 4.15.0-106-generic x86_64）的实例上安装 Docker。

当前环境是ubuntu server 20，安装了nginx。现在想要实现的是http://192.168.1.5/c1234 --> http://192.168.1.5:8081/webhttp://192.168.1.5/c5678 --> http://192.168.1.5:8082/web

当前环境是 ubuntu server 20，已安装 nginx。

现在我想要实现的是 http://192.168.1.5/c1234 --> http://192.168.1.5:8081/web

http://192.168.1.5/c5678 --> http://192.168.1.5:8082/web

端口信息存储在 csv 文件中，例如

c1234=8081
c5678=8082

是否可以使用 grep 来获取该端口？

我应该搜索什么关键词？代理、转发还是重写？欢迎任何网页链接。

谢谢

Nginx 反向代理 可以对此有所帮助。

此设置允许您根据路径将来自 Nginx 的传入请求重定向到后端服务器。

location ~ ^/c1234(.*)$ {
    proxy_pass http://127.0.0.1:8081/web$1;
}

location ~ ^/c5678(.*)$ {
    proxy_pass http://127.0.0.1:8082/web$1;
}

• p2

• p3

• p4

测试配置并重新加载 NGINX

sudo nginx -t
sudo systemctl reload nginx

你应该能够实现

http://192.168.1.5/c1234 --> http://192.168.1.5:8081/web

http://192.168.1.5/c5678 --> http://192.168.1.5:8082/web

要了解更多信息，请参阅下一个文档：

https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/

谢谢。如果该端口信息存储在文件中，是否可以使用 linux grep 获取该端口？原始帖子已编辑

我的意思是，你可以通过运行 python 脚本或 shell 脚本或类似的东西来读取 CSV 文件，因为 NGINX 配置是静态的，所以为了实现这一点，你应该在每次配置更改时运行代码，据我所知 NGINX 不支持像 grep 这样的命令

谢谢，我想我明白你的意思了。首先使用 shell 脚本读取 csv，然后生成该 NGINX 配置。
