I followed the zabbix docs available on https://www.zabbix.com/documentation/doku.php?id=2.0/manual/installation/install Installation from source
I have the web part up and running and I get Zabbix server is running: NO as status message. I checked the log file and I see these two lines everytime I try to start the server:
zabbix_server [61503]: cannot create Semaphore: [13] Permission denied
zabbix_server [61503]: unable to create mutex for log file
Anybody familiar with semaphores on OSX?
The problem I encountered, producing the same error, was that the web server runs as user _www and zabbix runs as user zabbix. I installed via MacPorts and am using the default Apache server. The semaphore is created with 660 permissions, so one or the other user is unable to access it.

Semaphores:

s 655368 0x7a03e3ce --ra-ra---- _www _www
s 458761 0x7a03e2ed --ra------- _www _www
s 524298 0x7a03e559 --ra-ra---- _www _www
s 65547 0x7a0312c8 --ra------- zabbix zabbix
Rather than mess with the semaphore creation or group membership, I patched the zabbix_server.init file and run zebbix as user _www.
