So. I finally decided it was time to set up my production server.
New install using yum as per the instructions. I did an uninstall and re-install just now to make sure my fiddling hadn't messed things up.
Version 2.2.1 on Centos 6.7
I had to set MAX_MAP_COUNT= as I am running an a Parrallels VPS.
I now get:
Starting elasticsearch: log4j:WARN No appenders could be found for logger (common).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
[ OK ]
The [OK] is a lie. ps -A reveals no elasticsearch running.
The /var/lib/elasticsearch directory has elasticsearch as user and goup and I am running a fresh install of Java 1.8.0_71
Any ideas how to get things working? I hope so as I have run out of homebrew to drown any sorrows in.
