Changing the location of the emacs server socket

Question

When I run emacs --daemon it creates a socket at /tmp/emacs1000/server

How can I tell it to use a different location?

Answer 1

The directory where the socket is created is controlled by this variable:

(defvar server-socket-dir
  (and (featurep 'make-network-process '(:family local))
   (format "%s/emacs%d" (or (getenv "TMPDIR") "/tmp") (user-uid)))
  "The directory in which to place the server socket.
  If local sockets are not supported, this is nil.")

If you use tcp sockets (probably not a good idea), the variable is server-auth-dir with value ~/.emacs.d/server/.

The name of the socket is the name of the server, as @DoMiNeLa10 notes in a comment, and can be changed by customizing the value of the variable server-name.
