[Plugin: EWWW Image Optimizer] You are missing: jpegtran, optipng, gifsicle

I’m assuming you’ve done the ‘make install’ command which puts the utilities in the system paths, correct? As in, you’re not running them via something like /home/username/optipng/src/optipng…

Then, what we need to know is the result of this command:
which optipng

Also, please ensure that you are not running PHP in safe mode, or have the exec() function disabled in PHP.

Hi. Look:

# which optipng
/usr/local/bin/optipng

PHP Safe Mode Off

something else may be need checking?

can you run the ‘which’ command for jpegtran & gifsicle also?

Ok, here’s another thought… What happens if you run those ‘which’ commands as the www-data user? If you get output, then we’re ok, otherwise, something is wrong.

I’m also going to try and put together a little debug script over the next couple days that gives a little bit more output about the tests we normally run in the background with the plugin.

Hello.
Yes, i can. Look:

# which jpegtran
/usr/local/bin/jpegtran

# which gifsicle
/usr/local/bin/gifsicle

I said you: it’s works from command line, and works from another usernames too.

Look:

# su www-data
$ # which gifsicle
/usr/local/bin/gifsicle$
gifsicle: <stdin>: is a terminal
$ optipng -v

$ exit

Yes, what I was looking for specifically is whether or not the ‘which’ command is working under the www-data user, since that is specifically how we test for the existence of the tools. I’m a bit stumped at this point, so I’m going to start brainstorming on that debugging tool.

Ok, I’ve got some basic info added to the plugin settings page. Please download the Development Version (over on the Developers tab/page), and paste the Debug section here.

Hi!

Look:

Debug information
computed jpegtran path: jpegtran
jpegtran location (using ‘which’):
computed optipng path: optipng
optipng location (using ‘which’):
optipng version:
computed gifsicle path: gifsicle
gifsicle location (using ‘which’):
gifsicle version:
safe mode: Off
Operating System: Linux
exec(): enabled
getimagesize(): OK
mime_content_type(): OK

This plugin can’t find a path to libraries? o_O

PS. I use a Apache2 ITK.

In particular, it appears the user running your webserver process can’t use the ‘which’ command, but likely it won’t find any of the others either.
I had never heard of ITK, so I did some research, and it appears that apache ITK runs as root, and then drops each child process into limited privileges as a different user, defined in the vhost configuration. So what you need to do it seems, is actually find out what user is specified in your VirtualHost config, and find out why that user can’t run any of the binaries.
I would suspect that will get us going on the right track (hopefully).

Ops, you right. Apache ITK does not give permissions. Good security ??
And I not found a solution to this problem.

If you can find a solution (or I’ll find) – let’s write here. Google is already grab this message, I think it would be usefull.

The same problem here:

installed via
yum install optipng

p.s. i’m using ordinary apache 2

lol i was so much sure that it is not my mistake.

it was like this in php.ini
;disable_functions = exec,passthru,shell_exec,system,proc_open,popen

so your debug is not debugging well ; )

KOKON, please don’t post your issue here unless you are using apache ITK.

I will respond once you have started your own support thread.
