Re: [squid-users] Help with running 2 instances of squid
Hello, I have three versions of squid running on the same machine, two in production and one for development. The best way that I found was to have three entirely separate compiles for each version where I actually change the names of the squid executables, config files, directory structures, pids, ports, etc. Then I fire them off independently with separate init.d scripts (I work under linux). BTW, I call different redirectors with each 'version' of squid. I guess it depends on circumstances. I originally thought of using seperate installs of Squid for each task, but we're working on a commercial product and really want to avoid the need to manage two packages for Squid instead of one. The problem has been narrowed down to the second init.d script to start the second squid instance, as I can manually start each squid from the relevant conf file without error.

HEllo, Are you also starting the squid with the other configuration file?

it makes no difference to the error message by adding or removing the '-f

Re: [squid-users] Help with running 2 instances of squid
Ok, if I manually start the squid instances using 'squid -f /etc/squid.conf' and 'squid -f /etc/squid2.conf' then it all works correcttly. I'm therefire guessing that I haven't edited the init.d script correctly!] Any pointers based on the script I posted in my previous message?

I copied the original squid start up script and believe I have edited it to start a second instance. I have set pid_filename in the second 'squid2.conf' file to be a different pid_filename and the init.d script still gives the same error. I'm guessing it's a fault with my editing of the script since if I start two squid's manually (squid -f /etc/squid.confandsquid -f /etc/squid2.conf) then it works without problems. I posted the script to this list about an hour ago to see if someone can spot what I have missed. Regards, Chris _ Hotmail messages direct to your mobile phone http://www.msn.co.uk/msnmobile

If starting Squid manually with -f arguments work fine then the Squid parts of things are done, and all that remains is to get the init scripts operating correctly. Assuming the init scripts are shell scripts you may be able to trace what the script are doing by running it as sh -x /path/to/initscript start or by inserting set -x commands at carefully selected locations.
