Squid cache not starting in Ubuntu 16.04.2 LTS

  • 772

I'm trying to start Squid (3.5.12) by the following command:

$ /etc/init.d/squid start

[ ok ] Starting squid (via systemctl): squid.service.

but only one line appears in cache.log, and nothing else:

2017/03/23 18:44:40| Set Current Directory to /var/spool/squid/cache

I did run squid -z.

My squid.conf looks as shown below:

  1. Current Ubuntu LTS (16.04) system services should be best managed via systemd which means in your case that to start, check status, stop squid you would use (respectively):

    # systemctl start squid
# systemctl status squid
# systemctl stop squid

    the service command is also still supported for backward System V compatibility, but it might disappear in the future. Running services by invoking directly

    # /etc/init.d/servicename

    is not supported/recommended.

  2. Solution was not to use /etc/init.d/squid start .

    service squid restart is working ok.

    Don't know why line 2017/03/23 18:44:40| Set Current Directory to /var/spool/squid/cache appeared in logs.
