To run oxidized as service


1. copy init script from oxidized/extra

 cp /usr/local/rvm/gems/ruby-2.3.0/gems/oxidized-0.24.0/extra/oxidized.init.d /etc/init.d/<br />

2. if you installed oxidized using manual (added system user oxidized) and rvm you need to modify script

#cmd=oxidized
cmd="sudo -u oxidized /usr/local/rvm/gems/ruby-2.3.0/wrappers/oxidized"
args="--daemonize"

#pidfile=/etc/oxidized/pid
pidfile=/home/oxidized/.config/oxidized/pid


#export OXIDIZED_HOME=/etc/oxidized
export OXIDIZED_HOME=/home/oxidized/

3. after that start as normal service

# /etc/rc.d/init.d/oxidized start

# /etc/rc.d/init.d/oxidized status
