Subject RE: How to Start Trafficserver on Init (Ubuntu Precise 12.04)
Date Fri, 15 Feb 2013 15:16:12 GMT
Ubuntu can be weird with some sudo commands, frequently the cause is missing environment settings
or it gets confused by the trailing &. To rule that out, and possibly give you better
error messages or results, try running your commands like this to see if it works better for

[brad@servername ~]$ sudo su - 
[root@servername ~]# trafficserver start

Then see what is running. Mine looks like this (on RHEL, not Ubuntu, but should be similar
with yours being in /usr/bin)

[root@servername ~]# ps -ef|grep traff
root      6797     1  0 Jan15 ?        00:00:21 /usr/local/bin/traffic_cop
nobody    6799  6797  0 Jan15 ?        00:10:05 /usr/local/bin/traffic_manager
nobody    6834  6799  1 Jan15 ?        11:44:36 /usr/local/bin/traffic_server -M --httpport
root      7903  7833  0 07:10 pts/0    00:00:00 grep traff

Thanks a lot for the ideas. Nice script! When I know more about this product I'm sure I'll
appreciate it even more...

I reviewed the script and see right off the bat that there are some inconsistencies among
platforms and/or versions. For example, in your script you use the trafficserver command (located
in /usr/local/bin) to control the server. On my installation (Ubuntu precise 12.04) that command
doesn't exist (probably because I installed it from a package). Rather, there are a series
of commands in /urs/bin starting with traffic_*

Somewhere else on the interwebs I saw someone say you should use traffic_manager to control
the server, but there is no man page associated with the program. If I run "sudo traffic_manager
start" everything seems to run properly but "sudo traffic_manager start &" or "sudo nohup
traffic_manager start" a really weird thing happens.... the process continues to run but the
command returns either 1 or 2 (can't remember) with a message saying it quit, and although
ps ax shows the service running, users seem unable to connect (but I could be wrong about
that... haven't tested thoroughly enough because I saw the error).

I've also tried using traffic_line as documented here:

but no love here either. The result of the command "sudo traffic_line -L" (which the documentation
would lead me to believe is to start up the service) is "error: the requested command failed"

So, any additional pointers would be greatly appreciated!
