I am looking for suggestions on a newer or slightly altered startup
script for use with squid 3.4.5 and CentOS based system (Scientific
Linux 6.5).
The issue is after a system reboot, during startup the ssl_crtd helpers
are crashing causing squid to not load on startup. Yet we can do a
"service squid start" immediately after it stops, and it starts and
works fine until the next reboot. I suspect there is something needed in
the script to avert this issue since it is a newer squid. I tried the
one that came with the 3.4.5 (squid.rc) but it is not functioning
properly on this system.
We have tried a delay script of up to 2 minutes and that is not helping,
any initial statup still has the same problem.
This is a remote server and we need it to work on startup without
needing to do extra time via SSH after it reboots to start it up every
time, especially once we roll this out to the 5 other servers. I've
checked the squid.out, cache.log and other squid and system related logs
and none of them give us any idea of why it is doing that only at startup.
12 seconds after initial startup attempt and multiple ssl_crtd helper
crashes:
Jun 25 23:25:47 i3540 (squid-1): The ssl_crtd helpers are crashing too
rapidly, need help!
Jun 25 23:25:47 i3540 squid[1674]: Squid Parent: (squid-1) process 1762
exited with status 1
Jun 25 23:25:47 i3540 squid[1674]: Squid Parent: (squid-1) process 1762
will not be restarted due to repeated, frequent failures
Jun 25 23:25:47 i3540 squid[1674]: Exiting due to repeated, frequent
failures
Then after we do a "service squid start":
Jun 25 23:26:24 i3540 squid[1810]: Squid Parent: will start 1 kids
Jun 25 23:26:25 i3540 squid[1810]: Squid Parent: (squid-1) process 1812
started
and no more crashes.
I have tried at least 3 or 4 versions online and none of them work.
Either they do not work properly with "service squid start" or there are
other issues.
My current squid init script which was borrowed from a previous version
(3.1.10). again, everything works except the ssl_crtd crashing ONLY on
startup after a reboot:

# Description: Squid - Internet Object Cache. Internet object caching is \
# a way to store requested Internet objects (i.e., data available \
# via the HTTP, FTP, and gopher protocols) on a system closer to the \
# requesting site than to the source. Web browsers can then use the \
# local Squid cache as a proxy HTTP server, reducing access time as \
# well as bandwidth consumption.
