Okay, got my machine up and running and trying to get the server stuff set
up. First, I'm working on the NTP server part of things. This is a field
network with no Internet access, so I am providing time synchronization via
ntp with a GPS USB puck. Basically, I have it all working when I run things
manually. However, when I boot up or restart the computer, gpsd and ntpd
are not coming up as desired.
What I want:
$ ps ax | grep gps
13878 ? S<sl 0:04 gpsd -n /dev/ttyUSB0
$ ps ax | grep ntp
13897 ? Ss 0:00 ntpd -gN
What I get on reboot:
$ ps ax | grep gps
3297 ? S<s 0:09 /usr/sbin/gpsd -N
$ ps ax | grep ntp
3314 ? Ss 0:00 /usr/sbin/ntpd -u ntp:ntp -g
Apparently, there is some place I need to configure so these things start
with the right parameters. However, I have not played with CentOS for about
5 or 6 years, I am old and suffer from CRS, and simply cannot remember
where to do this.
I can kill the gpsd and ntpd processes and restart them from command line
and things work fine, but they don't on initial boot.
I'm assuming you are running CentOS 7, and that you have installed gpsd
from epel and ntp from the standard repository. The configuration files
are here:
/etc/sysconfig/gpsd
/etc/sysconfig/ntpd
I see a couple of ways to get tripped up while trying to get this
running. The first is selinux, and the second is permissions set by
udev on the serial port.
Note that I'm not running either of these daemons. Caveat emptor
