I am installing InfiniteWP on a local environment using MAMP. Everything works perfectly except for my inability to figure out how to setup a cronjob properly. I did find some information (dated?).
I found this: http://www.freewaytalk.net/thread/view/114906 . But am a bit worried that I may be implementing something dated.
The instruction given by InfiniteWP in order to start the cronjob say this:"php -q -d safe_mode=Off /Applications/MAMP/htdocs/IWP/cron.php >/dev/null 2>&1" So I need instruction on how to implement this php command on my Mac. Terminal?
I'd really appreciate advice and validation on the best course of action.
You could always use a GUI such as : http://code.google.com/p/cronnix/
This is simply a front end to the crontab tool, then simply set the time you want it to run and the URL to:
/Applications/MAMP/htdocs/IWP/cron.php
I didn't have any luck with that google code option but Mac has cron natively and your InfiniteWP code can be added in a few lines. See instructions here: http://www.maclife.com/article/columns/terminal_101_creating_cron_jobs

I am trying to build a small custom task scheduler. Basically the idea is I have cron run my process script, which looks in the database and finds any scheduled tasks that are ready to run, and runs them. So I think the best way to do this would be to try to launch the tasks "in the background" by way of shell_exec and using > /dev/null, which I understand makes it so the initial script (the process script) doesn't wait for the task scripts to complete.
So first, if there is a better way to achieve this, I'm open to suggestions. Though note I am on php 5.3 so there may be some options in 5.4 and up that I don't have access to :(
However here's the question at hand:
I am testing on WAMP on my windows machine and I am trying to make a call that looks like this:
shell_exec("php $path$base_url$querystring > output_test.txt 2>&1 &");
$path is the full windows path to the script
$base_url is the base url of the script I am calling
$querystring is of course the query string being passed to the task script
I am also outputting to output_test.txt which creates such file in same directory, where I get the following error:
Could not open input file:
C:\xampp\htdocs\email\batch_email_send_u2u.php?dealer=7
Yes I realize the path references an xampp installation, but that is not the issue - all the wamp files are executing from there and everything else has worked like this for years - it was just set up this way to support a legacy setup.
It seems to me shell_exec is locating and running php, it's just that it can't open the referenced script. Can't figure out why.
Also I need to eventually get this working on a real linux server so any advice on how to make that happen would be greatly appreciated!
Found a solution! Special thanks to dan08 for getting me set on the right path.
Ultimately I found the answer in this thread: Pass variable to php script running from command line
I ended up using the argv[] array as described in that post and with a little tweak to the script I'm calling it works like a champ now.
I would like to be able to either launch php in interactive mode via phing or via PHP (worst case scenario, phing can run an adhoc task with the desired code).
I've gotten this far:
<?php
$cmd = 'php -d auto_prepend_file=bootstrap.php -a';
passthru($cmd)
And the above almost gets me what I want. I enter a shell I can interact with, but the prompts are gone (the php > at the start of each line), all meta-commands (e.g., \>) totally fail, and typing exit; does nothing instead of exit the shell. So, as you can see, this isn't the ideal shell. Is this even possible without installing phpsh?
Thanks in advance.
I think PsySH will give you want you want. It's a PHP REPL that gives you the option to configure it to automatically include a bootstrap file.
I am trying to do a simple project to start a VirtualBox VM using a PHP script. My server is win 7 ultimate and running php5.3 I am using the vboxmanage.exe to start the server. cmd works great in a batch file or typed right into cmd line.
When I use:
exec("path to vboxmange.exe" startvm "vm name");
it doesnt work. If I change the code to:
exec(dir);
it works fine. I did some searching and everyone seemed to mention permissions for IIS_IUSRS. I set it to have read and execute on the vboxmanage.exe and tried to do it for cmd.exe but cant seem to get it to allow me to do this, though it doesnt seem necessary as it can run other cmds like dir.
another theory I have is that exec wraps the entire cmd in "" and this doesnt work when I try to type it in to cmd line manually. I have tried to trim it off but that doesnt work cause exec adds it on so nothing I do before can stop this.
any suggestions for another way to do this or what it might be?
From exec in the PHP Manual:
Note: When safe mode is enabled, you can only execute files within the
safe_mode_exec_dir. For practical reasons, it is currently not allowed
to have .. components in the path to the executable.
Check the value of your safe_mode_exec_dir in your php.ini. I would guess that it would be fairly restrictive by default.
If that doesn't work, take a look in the comments. Particularly, this comment might be of help to you.
First, I read some threads by people with similar problems but all answers didn't go beyond export DISPLAY=:0.0 and xauth cookies. So here is my problem and thanks in advance for your time!
I have developed a little library which renders shelves using OpenGL and GLSL.
Last few days I wrapped it in a php extension and surprisingly easy it works now.
But the problem is it works only when I execute the php script using the extension from commandline
$php r100.php(i successfuly run this from the http user). The script is in the webroot of apache and if I request it from the browser I get ** CRITICAL **: Unable to open display in apache's error_log.
So, to make things easier to test and to be sure that the problem is not in the library/extension, at the moment I just want to start xmms with following php script.
<?php
echo shell_exec("xmms");
?>
It works only from the shell too.
I've played with apache configuration so much now that I really dont know what to try.
I tried $xhost + && export DISPLAY=:0.0
In the http.conf I have these
SetEnv DISPLAY :0.0 SetEnv XAUTHORITY /home/OpenGL/.Xauthority
So my problem seems to be this:
How can I make apache execute php script with all privileges that the http user has, including the environment?
Additional information:
HTTP is in video and users groups and has a login shell(bash).
I can login as http and execute scripts with no problem and can run GUI programs which show up on display 0.
It seems that apache does not provide the appropriate environment for the script.
I read about some difference between CLI/CGI but cant run xmms with php-cgi too...
Any ideas for additional configuration?
Regards
Sounds bit hazard, but basically you can add even export DISPLAY=:0.0 to apache start-up script (like in Linux /etc/init.d/httpd or apache depending distro).
And "xhost +" need to be run on account which is connected to local X server as user, though I'm only wondering how it will work as php script should only live while apache http request is on-going.
Edit:
Is this is kind of application launcher?, you can spawn this with exec("nohub /usr/bin/php script.php &"); .. now apache should be released and php should continue working in background.
In your console, allow everyone to use the X server:
xhost +
In your PHP script, set the DISPLAY variable while executing the commands:
DISPLAY=:0 glxgears 2>&1
I have a program that returns a comma-separated string of numbers after doing some background processing. I intended to run this in symfony using shell_exec; however, all I get is NULL (revealed through a var_dump(). I tried the following debugging steps.
I ran the file (it's a PHP class) through a command-line lime unit test in Symfony - it works and gives the correct result there.
Just to check, I tried a simple command ls -l at the same place to see whether I would get anything. Again, I had the same problem - the var_dump in the browser showed NULL, but it worked through the command line.
What could be the problem? Are there restrictions on running shell_exec() in a browser?
EDIT: Just to clarify, shell_exec() commands work when I run them as standalone php scripts on the web server (for example, by putting them in my document root. They don't seem to be working under the symfony framework, for some reason.
I finally solved it, and it turned out to be something quite simple, and quite unrelated.
The shell command I was running was in this format: face_query -D args. I didn't realize that Apache would be executing PHP as user www-data and thus the program face_query wouldn't be in the PATH (the directory is actually ~/bin). Changing the program name to the full path of the program solved it.
I also gather from this that only commands which www-data has permission to execute can be run. In this case, www-data is in the same group as my user, but it might be a problem otherwise.
Have you tried using exec? Or one of the other variants. I am never sure of which one to use and always lump with exec.

Is your web server running php in safe mode?
