Start up Cache instance on OSX
Hi, everybody
I am newbie at OSX and I am trying to install Cache on my mac
At first time I just executed in Shell Terminal next line
$ sudo /Users/Alex/Downloads/cache-2016.2.0.627.0-macx64/cinstall
And there was no problems with instalation.
But few day after first try I've decided to update it to 2016.2.0.719.0 and I deleted previously installed version by "sudo rm -r <directory>" and only then I've tried to google "how to uninstall cache" and learned that I have had to stop instances and delete them by ccontrol first. My fault. Just in case it helps I did it
Then I.ve tried to execute next line
sudo /Users/Alex/Downloads/cache-2016.2.0.719.0-macx64/cinstall
Installation was going normally but then on task "Starting up Cache" next error was printed in terminal
Error: ERROR #5001: Could not start SuperServer on port 1972, may be in use by another instance - Shutting down the system
An error was detected during Cache startup.
** Startup aborted **
And "ccontrol start" prints the same error
$ ccontrol start cache
Starting CACHE

Can someone help me with this issue.
I have been Windows user, and I did not faced with any similar issues.
Such error you can face on a windows as well. Your super port has already in use by another instance of Cache. And you can change port for new instance, by editing cache.cpf file in the root of installed Cache.
To be sure that port is in use you can use some network tools, such as netstat
or lsof, which can show which process with pid uses this port
How it can be if "ccontrol list" prints next
$ ccontrol list
Configuration 'CACHE'
directory: /Users/Alex/work/cache
versionid: 2016.2.0.719.0
conf file: cache.cpf (SuperServer port = 1972, WebServer = 57772)
status: down, last used Sat Aug 27 17:13:55 2016
Could you tell me how to remove all remaining traces of the previous instance
Thanks in advance.
does not matter what `ccontrol list` shows, may be you just removed instance from this list
if you removed this folder, try to restart machine, and check output with commands, which I gave you
Thank you
Restart of machine helped, didn't thought that it would help
Hi Alexander,
The problem was: with just removing the directory, the processes are still hanging around. So the 1972 port was still in use by the original cache instance.
Restarting removed that process, that's why it solved the issue. Part of Dmitry's answer was useful in such as you can use lsof to determine which process holds a handle on a port.
Please let me know if you have any further questions about this!
HTH,
Fab
