Services
VM for hosting new EWX.
Restarting the EWX WebApp
In the event of a reboot, restart EWX via two files (as ewx)
/opt/tomcat/bin/catalina.sh start #Verbose, can be halted - startup.sh in the same directory also works #use ewx's alias to take you to the correct geoengine directory geoe #Geoengine needs to be run a bit after catalina.sh startup.sh
Notes
- Domain changed from geog.ucsb.edu to chg.ucsb.edu as of November 23rd, 2015 (can also be reached via ewx.chg.ucsb.edu).
- 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
