mkfifo这是个文件夹还是什么文件,我创建了这个文件夹,并且把权限设置成777了

[powerLxc]

配置文件里面的mkfifo.path的路径我定义在/monchickey/mkfifo

[glaciall]

mkfifo是一个命令行，是linux下所特有的一个，你先通过which mkfifo来确定一下它的路径，一般情况下都是默认路径，你不需要改的，我只是提供了一个修改的可能性，如果你的位置不一样才需要改它，你恢复成原样的就好了，那个fifo-pool.path才是一个目录。。。。这里保存fifo命令管道文件的。。。。

[glaciall]

很可耻的是我忘了给配置文件写注释了，真是不好意思，今天晚上我改一改。。。。

谢谢解答
