Notes

• System should be fully gNIS integrated.
• Created symbolic link in /usr/local/bin to point from python2.7 to python to address a script not running. Marty altered the files /etc/init.d/tomcat, /opt/tomcat/bin/startup.sh, and /opt/tomcat/bin/catalina.sh Libby 16:24, 24 February 2015 (PST)
• For some reason, the ntpd service was stopped or not set up to start at startup, so hwclock and date were not sync. Should be resolved now. Libby 12:14, 25 February 2015 (PST)
  • ntpd service somehow got turned off again and 'date' was an hour off Libby 12:28, 7 May 2015 (PDT)

[root@chg-ewx ~]# service ntpd status
ntpd dead but pid file exists

To restart the service:

[root@chg-ewx ~]# service ntpd restart
Shutting down ntpd:                                        [FAILED]
Starting ntpd:                                             [  OK  ]

It may say that shutting down failed (if pid is still floating around out there) but you can check to see if it's running and that the clock is back to syncing with the following:

[root@chg-ewx ~]# service ntpd status
ntpd (pid  15430) is running...
[root@chg-ewx ~]# hwclock
Thu 07 May 2015 01:20:06 PM PDT  -0.102682 seconds
[root@chg-ewx ~]# date
Thu May  7 13:20:17 PDT 2015

• In the event of a reboot, restart EWX via two files (as ewx)

/opt/tomcat/bin/catalina.sh 
/opt/geoengine-3.0.0/startup.sh
