Unix域(AF_UNIX)套接字的端点(文件)放在哪里?

问题描述

是否有约定将表示端点的文件"放置到Unix域套接字?

Is there a convention where to place the 'files' representing the end points to Unix Domain Sockets?

我倾向于将它们放到/tmp/some-application-specific-subdir-name/，但是我想知道是否还有更常见的地方.

I tend to put them to /tmp/some-application-specific-subdir-name/, but I wonder if there is a more common place.

背景是， POSIX 不清楚关于访问这样的文件"的最大路径长度:

The background is, that POSIX is not clear about the maximum path length to access such 'files':

应用程序不应假定sun_path的特定长度，也不能假定它可以容纳{_POSIX_PATH_MAX}个字节(256).

Applications should not assume a particular length for sun_path or assume that it can hold {_POSIX_PATH_MAX} bytes (256).

因此，应将路径长度的这种限制"排除在应用程序的文件/路径名称配置之外.

So this "restriction" on the path's length should be kept out of the application's file/path name configurations.

推荐答案

FHS 说: /run

(它以前是 /var/run .)

(It used to be /var/run.)
