Lacquered DAEMON_OPTS errors

When using inline C with Varnish, I was unable to get / etc / lnn / default to
be happy at startup.

I tested inline C with varnish for two things: GeoIP detection and Anti-Site-Scraping features.

DAEMON_OPTS always complains, despite the fact that I follow others to show that the work is wonderful.

My problem is that running this command line works:

varnishd -f /etc/varnish/varnish-default.conf -s file,/var/lib/varnish/varnish_storage.bin,512M -T 127.0.0.1:2000 -a 0.0.0.0:8080 -p 'cc_command=exec cc -fpic -shared -Wl,-x -L/usr/include/libmemcached/memcached.h -lmemcached -o %o %s'

But he is mistaken when trying to run default startup scripts:

/ etc / default / lnn has this in it:

DAEMON_OPTS="-a :8080 \
             -T localhost:2000 \
             -f /etc/varnish/varnish-default.conf \
             -s file,/var/lib/varnish/varnish_storage.bin,512M \
             -p 'cc_command=exec cc -fpic -shared -Wl,-x -L/usr/include/libmemcached/memcached.h -lmemcached -o %o %s'"

Error:

# /etc/init.d/varnish start
Starting HTTP accelerator: varnishd failed!
storage_file: filename: /var/lib/varnish/vbox.local/varnish_storage.bin size 512 MB.
Error:
Unknown parameter "'cc_command".

If I try to change the last line to:

-p cc_command='exec cc -fpic -shared -Wl,-x -L/usr/include/libmemcached/memcached.h -lmemcached -o %o %s'"

Now this error:

# /etc/init.d/varnish start
Starting HTTP accelerator: varnishd failed!
storage_file: filename: /var/lib/varnish/vbox.local/varnish_storage.bin size 512 MB.
Error: Unknown storage method "hared"

It tries to interpret '-shared' as -s hared and 'hared' is not a storage type.

You can try: - DAEMON_OPTS = "- a: 8080 \ -T localhost: 2000 \ -f / etc / varnish / varnish-default.conf \ -s file, / var / lib / varnish / varnish_storage.bin, 512M \ - p cc_command = 'exec cc -fpic -shared -Wl, -x -L / usr / include / libmemcached / memcached.h -lmemcached -o% o% s' "
