Suggested init.d startup script.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Any help on this would be appreciated
