Reload Squid Proxy Server Without Restarting Squid Daemon

by

You can reload the Squid proxy server configuration without restarting the Squid daemon by sending a SIGHUP signal to the Squid process. This will cause Squid to reread its configuration file, squid.conf, and apply any changes.

Here’s how to reload the Squid proxy server on a Linux system:

  1. Find the process ID (PID) of the Squid daemon You can use the following command to find the PID of the Squid daemon:
    $ ps aux | grep squid

    This will display a list of all running processes that contain the string “squid”. The first column of the output will show the PID of the Squid daemon.

  2. Send the SIGHUP signal to the Squid daemon Once you have the PID of the Squid daemon, you can use the following command to send the SIGHUP signal:
    $ kill -HUP PID

    Replace PID with the actual PID of the Squid daemon.

This will cause Squid to reread its configuration file and apply any changes, without having to restart the Squid daemon. You can verify that the reload was successful by checking the Squid logs for any error messages.
