How to set Varnish to run on port 80. Malfunction of DAEMON_OPTS set in /etc/default/varnish -

i have installed varnish , fallowed exact instruction setting up, however, not working expected.

my /etc/default/varnish setup is:

daemon_opts="-a :80 \              -t localhost:1234 \              -f /etc/varnish/default.vcl \              -s /etc/varnish/secret \              -s malloc,256m" 

my /etc/varnish/default.vlc setup is

backend default {     .host = "localhost";     .port = "8080"; } 

my apache port.conf setup is:

namevirtualhost 127.0.0.1:8080 listen 127.0.0.1:8080  <ifmodule ssl_module>         listen 443 </ifmodule>  <ifmodule mod_gnutls.c>         listen 443 </ifmodule> 

i running ubuntu 15.04 apache 2.4.10. when start varnish , check process fallowing:

0:00 /usr/sbin/varnishd -a :6081 -t localhost:6082 -f /etc/varnish/default.vcl -s /etc/varnish/secret -s malloc,256m 

seems neither of listen address or management interface work set in /etc/varnish/default.vcl. none of virtual machines work result. how can solve ?

ok. problem solved. first

sudo grep -r 'execstart=/usr/sbin/varnishd' /etc/ 

so can find other place daemon options varnish set (in case /etc/systemd/system/multi-user.target.wants/varnish.service). open file in vim,nano or whatever , set "execstart" in file fallows:

-a :[same /etc/default/varnish]80 -t localhost:[same /etc/default/varnish]1234 -f [same /etc/default/varnish ]/etc/varnish/default.vcl -s [same /etc/default/varnish ]/etc/varnish/secret -s malloc,256m 

save , exit. after do:

systemctl daemon-reload systemctl restart varnish.service 

and done. nothing official tutorial. apparently old.
