Linuxbrew Nodejs - 绑定到端口80

Question

我想解决this issue中描述的同样问题。

因此我想执行以下命令：

$ sudo setcap cap_net_bind_service=+ep /home/username/.linuxbrew/bin/node 

这产生了错误：

Failed to set capabilities on file `/home/username/.linuxbrew/bin/node' (Invalid argument)
The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file

是否会发生这种情况，因为foldername是 .linuxbrew ，如果是，我该如何解决？

Answer 1

这是因为你试图在符号链接上运行它。请尝试运行此代码：

sudo setcap cap_net_bind_service=+ep $(readlink -f ~username/.linuxbrew/node)
