pass env variable to traffic_server via traffic_cop

[毅程 <ph...@gmail.com>]

Hi:

I am wondering how to pass
export LD_LIBRARY_PATH=xxx
to traffic_server via traffic_cop, since I am using bin/trafficserver to
start traffic server.

if I start by using bin/traffic_server, I can export LD_LIBRARY_PATH=xx
directly and it works, but I am using trafficserver script, I do not know
how.

Many Thanks.

Linux will unset LD_LIBRARY_PATH (as well as some other env variables) when
you change users (decent explanation:
http://superuser.com/questions/153420/why-does-my-ld-library-path-get-unset-when-using-screen-with-bash).
The only way to get around this is to *not* change the user id between
traffic_cop/manager/server. You can do this by setting the admin.user_id (
http://trafficserver.readthedocs.org/en/latest/reference/configuration/records.config.en.html?highlight=body%20factory#proxy-config-admin-user-id)
to #-1, which will not change the user between the processes-- which will
maintain the env variables.
