从 WSL2 内部访问在 Windows 中运行的本地主机?

问题描述：

我在我的 Windows 机器中运行本地 AEM 服务器.服务器在 localhost:4502 上运行.我正在使用在 WSL2 中运行的 Ubuntu 发行版进行开发.我想访问在我的 WSL2 Ubuntu 中的 Windows 机器上运行的 localhost:4502.

I am running a local AEM server in my Windows machine. The server is running on localhost:4502. I am using Ubuntu distro running in WSL2 for my development. I want to access the localhost:4502 running in the Windows machine in my WSL2 Ubuntu.

有没有办法做到这一点，或者不可能?

Is there any way to do that or is it not possible ?

答

我也在寻找一些解决方案来做到这一点，但目前没有这样的选项可用.查看此 GitHub 问题:

I was also looking for some solution to do this but currently, there is no such option available. Check out this GitHub issue:

一种解决方案是:

如果您拥有 windows(host) 的 IP，那么它将完成这项工作，但唯一的问题是 IP 每次都会更改.但是，WSL2 将您的 Windows(主机)IP 存储在 /etc/resolv.conf 文件中.所以我们可以修改我们的 etc/hosts 来动态映射 winhost 到 IP.

If you have the IP of windows(host) then it will do the job but the only problem is that IP will change every time. But, WSL2 stores your windows(host) IP in /etc/resolv.conf file. So we can modify our etc/hosts to map winhost to the IP dynamically.

在~/.bashrc 文件末尾添加以下几行.这将在启动 WSL 时 grep IP 并修改 etc/hosts.

Add the following lines at the end of ~/.bashrc file. This will grep the IP and modify the etc/hosts when you boot the WSL.

export winhost=$(cat /etc/resolv.conf | grep nameserver | awk '{ print $2 }')
if [ ! -n "$(grep -P "[[:space:]]winhost" /etc/hosts)" ]; then
        printf "%s\t%s\n" "$winhost" "winhost" | sudo tee -a "/etc/hosts"
fi

然后运行以下命令以重新加载更改.

then run the following command to reload the changes.

$ source ~/.bashrc

现在您可以在 WSL2(客户端)中使用 winhost 而不是 localhost 来访问运行 windows(主机)的服务器.在您的情况下，它将是 winhost:4502 但这将适用于任何其他用例以及访问在 Windows 等上运行的 Postgres/MySQL 服务器.

now you can use winhost instead of localhost in WSL2(client) to access the servers running windows(host). In your case, it will be winhost:4502 but this will work for any other use cases as well like accessing Postgres/MySQL server running on windows, etc.

注意:请始终记住在 Windows 上配置防火墙以允许这些端口，以便 WSL2 可以访问，否则您的连接可能会被防火墙阻止.

NOTE: Always remember to configure your firewall on windows to allow those ports so that WSL2 can access otherwise your connection may get blocked by firewall.
