We have provided answers.

We have also asked some questions, to help us understand what you are trying 
to do, and how best to help you further, but you have not answered these.

The current questions which I think it would be useful for us if you could 
answer are:

 - why are you trying to use rock store, rather than UFS?

 - what is the astonishing urgency about getting this done?

 - have you tried my earlier suggestion of uninstalling squid, deleting the 
squid.conf file, reinstalling squid, and then doing everything via webmin?

Whats the error?

BTW: you can expect valgrind to detect leak issues in any old version of
Squid. For values of 'old' including the very latest 3.5. Squid-4 is
getting close to having none show up, but there are still a few
intentional things.

Please read the file you are editing. I suggest you start at line
number 1 and read at least the top three paragraphs.

Somebody has "helpfully" moved the squid documentation file into place
where squid.conf usually is.

Then search for "TAG: cache_dir". The description you are asking for is
written in there.

I say "I don't understand what you're trying to tell me with that screenshot".

You have six lines in your squid.conf:

cache_dir rock /hdd1 ... min-size=10
cache_dir rock /ssd1 ... max-size=9
cache_dir rock /hdd2 ... min-size=10
cache_dir rock /ssd2 ... max-size=9
cache_dir rock /hdd3 ... min-size=10
cache_dir rock /ssd3 ... max-size=9

Those lines do not make sense.  I do not know whether you really do have 
directories /hdd1, /ssd1 etc on your machine, but even if you have, the "..." 
is wrong.

The correct format for configuring the rock store cache is (as documented a 
little higher up in squid.conf):

# cache_dir rock Directory-Name Mbytes [options]

Therefore you must change those six lines to have the correct format.


Alternatively you could just delete them, because you also have:

cache_dir ufs /var/spool/squid 100 16 256

which is almost certainly going to work (even if it gives you a very small 
cache).

No, I can't, because I do not know what the correct configuration is for:

a) *your* machine

b) *your* network

c) what *you* want to do with squid

I would recommend starting from the default squid.conf (in other words, remove 
the squid package from your machine, delete the squid.conf, then re-install 
the package, which should bring in a standard default configuration file, whoch 
does not have errors in it), and then manage the system using webmin (which I 
have almost no experience of, but I believe should be able to adjust your 
squid.conf for you if you don't want to do it yourself with a text editor).

As a starting guide, the *only* thing you normally need to change from a 
default squid.conf to get a working system is the section labelled:

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS

If you do not know what to put in there, tell us about your network and we can 
help you with some suggestions.

When I say "tell us about your network" I mean let us know:

1. The IP address and netmask of your squid server

2. The IP address range containing the client machines which you want to be 
able to use the squid server

3. The default gateway address used by the squid server

Now you need to configure squid.

Look at the documentation in /usr/share/doc/ for further details.

I would urge you to go read any Ubuntu administration guide online (there are a 
few). Some of them even cover squid, as shipped in Ubuntu.

Good luck.

Are you telling me that you did not modify the file squid.conf at all?

That file has errors in it (as your second screenshot displays clearly); these 
need correcting.  I believe I have given guidance on how to correct them.

Please see the questions in my previous email for information which we might 
find helpful to assist you in doing whatever it is you are trying to do.

Well, you should correct the mistakes so that the lines which are not 
commented match the documentation (hint: "..." is not a valid part of any 
line).

Quite how you should do this depends on what you are trying to achieve, which 
you haven't told us.

Some information which might be helpful if you want further assistance:

1. Do you want to use the UFS store type?
 - if so, which path on your machine do you want that cache to exist under?

2. Do you want to use the rock store type?
 - if so, which path on your macine do you want that cache to exist under?

3. How much storage space do you want to allocate for your cache/s?

4. What are you planning to use squid for?

You have just copied the sample configuration from the commented-out lines in 
squid.conf, without adapting them to where you want your cache to be and what 
size to use.

The comments tell you to use:

# cache_dir Type Directory-Name Fs-specific-data [options]

and specifically for the rock store type:

# cache_dir rock Directory-Name Mbytes [options]

So, you need to change your configuration lines:

cache_dir rock /hdd1 ... min-size=10
cache_dir rock /ssd1 ... max-size=9
cache_dir rock /hdd2 ... min-size=10
cache_dir rock /ssd2 ... max-size=9
cache_dir rock /hdd3 ... min-size=10
cache_dir rock /ssd3 ... max-size=9

so that they make sense according to the above format guidelines.  (Hint: the 
"..." above means "fill in the appropriate details", it doesn't mean "type 
three dots here").

However, since you also have a line:

cache_dir ufs /var/spool/squid 100 16 256

(which I notice is also copied direct from the sample in the documentation, 
making me wonder whether you have thought about what size you want your cache 
to be, for example)

why do you also have the 'rock' cache lines?


PS: In future please post your squid.conf without any comments or blank lines.

Regards,


Antony.

[james82]

Can someone tell me what should I do to fix on "this must be done before
squid can run"? I don't know this error.

Thanks Amos. I have updated to squid 3.5.20 (compiling from source) and it 
seems all is working ok, now.
