I need to send emails hourly and daily. I've tried nearly everything but it appears my crontab just won't work. If I run the scripts via a browser e.g
http://localhost/Maisha/Functions/sendhourlymails.php
my emails get sent beautifully.(I moved default website localhost to public_html.) I don't know whats wrong. I read some post in stack overflow including the executable path of php helps hence I've put the /usr/bin/php before the actual script to be cronned will work but it does not. Removing /usr/bin/php does not work. Adding php before the actual script isn't working.
I have the following entries in my crontab.
# m h dom mon dow command
0 * * * * /usr/bin/php /home/maxwell/public_html/Maisha/Functions/sendhourlymails.php
0 0 * * * /usr/bin/php /home/maxwell/public_html/Maisha/Functions/senddailymails.php
Try to call the script via http with wget like so:
* * * * * wget http://localhost/myscript >/dev/null 2>&1
Yeh, wget is good option, also you can try to use:
0 * * * * /usr/sbin/php /usr/bin/php /home/maxwell/public_html/Maisha/Functions/sendhourlymails.php
but it could work wrong due to relative paths.
Also you should look at http://php.net/manual/en/features.commandline.php
Try to put this into your .php file
<?php
#!/usr/local/bin/php -q
//your code here
?>
Then if you include any file into this file you must use something like:
include"/var/www/../your_absolute_path_from_root_folder/connect.php";
Finnaly make sure this file has the right permissions..Try
chmod 755 /var/www/.../file.php
Then if you edit your crontab file with the following command
vi /etc/crontab
put something like
10 6 * * * root php /var/www/..path../file.php
and restart the service with this command
/etc/init.d/cron restart
you have do your job!!
Note-Tip:the php file isn't neccessery to be into public_html
folder!!

I setup several cron jobs to make things work. laravel scheduler works perfectly but my other cronjobs not working at all.
*/2 * * * * /usr/bin/php /var/www/cronjobs/index.php
when I run on the console /usr/bin/php /var/www/cronjobs/index.php it works properly. I checked executable php path with which php and gives me /usr/bin/php nothing wrong with path afaik. I tried to run php script as apache user www-data I opened crontab with crontab -u www-data -e and paste command there.. it didn't work too.
I also tried send dummy notify with crontab and it also didn't work either
dummy example
* * * * * /usr/bin/notify-send 'test'
both of them doesn't work. What am I missing here ?
The second command will not send notification as cron have no idea of your desktop environment.
The first command probably use some environment variables. So instead of run in command line you can try to create a script:
#!/bin/bash
source /path/to/user/home/.bashrc #you can try also .bash_profile
/usr/bin/php /var/www/cronjobs/index.php
and your cron to be like:
*/2 * * * * /path/to/script.sh
I need to run a PHP file every 1 hour.
What I'm doing is:
sudo crontab -e
(In the editor) * 01 * * * /usr/bin/php /var/www/devicecheck.php
But somehow, it's not working. The command works on the command line. Before this, I was trying php /var/www/devicecheck.php
Any suggestions?
To execute devicecheck.php every 1 hour try the following:
Method A :: Execute the script using php from the crontab
# crontab -e
00 * * * * /usr/bin/php/var/www/devicecheck.php
Method B: Run the php script using URL from the crontab
If your php script can be invoked using an URL, you can lynx, or curl, or wget to setup your crontab as shown below.
The following script executes the php script (every hour) by calling the URL using the lynx text browser. Lynx text browser by default opens a URL in the interactive mode. However, as shown below, the -dump option in lynx command, dumps the output of the URL to the standard output.
00 * * * * lynx -dump http://www.yourwebsite.com/yourscript.php
The following script executes the php script (every 5 minutes) by calling the URL using CURL. Curl by default displays the output in the standard output. Using the “curl -o” option, you can also dump the output of your script to a temporary file as shown below.
*/5 * * * * /usr/bin/curl -o temp.txt http://www.yourwebsite.com/yourscript.php
The following script executes the php script (every 10 minutes) by calling the URL using WGET. The -q option indicates quite mode. The “-O temp.txt” indicates that the output will be send to the temporary file.
*/10 * * * * /usr/bin/wget -q -O temp.txt http://www.yourwebsite.com/yourscript.php
UPDATE::
# chmod a+x /home/username/yourscript.php
# crontab -e
00 * * * * /home/username/yourscript.php
Script should have execute permission. Give it by
chmod +x /var/www/devicecheck.php
Also check /var/log/syslog for Errors.
I got it to work with wget. You maybe have to install wget first. After it will allow you to run php scripts from a cronjob.
The syntax looks like:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php"
Where /usr/local/bin/wget points to the directory where wget is installed.
If you wish no output just add '-O /dev/null', like this:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php" -O /dev/null
You can also pass parameters in the url:
* 01 * * */usr/local/bin/wget "http://localhost/devicecheck.php?task=somevalue" -O /dev/null
I want to call a php script every minute using cron
i added the the below code in my crontab file
*/1 * * * * /usr/bin/php /var/www/html/test.php
but it dint give me the desired output.
Am i missing something?
Thanks in advance
You might want to check what happens when this php file runs by following
just use * instead of */1
* * * * * /usr/bin/php /var/www/html/test.php >> /var/www/html/test.txt
test.txt file will contain any error or anything else which cause your test.php to not working. and if it's not loading anything in test.txt, please double check your path to your file.
alternatively try running /usr/bin/php /var/www/html/test.php from your centos console to check whether everything ok with path to your 'php' and 'test.php' file.
I want a script file to run once every minute.. I've written this command.
* * * * * php -q /home/<username>/public_html/cron.php
But, this cronjob is not working. whenever, I try to open this file cron.php in browser, it works fine.
I'm using Linux OS. Is there a way to debug it in order to come to know the error?
If you're using Ubuntu as I am, use the full path.
* * * * * /usr/bin/php -q /home/<username>/public_html/cron.php
Have you added an empty line (new line) after your cronjob?
To debug:
Append 2>&1 to the end of your Crontab command. This will redirect the stderr output to the stdout. Then ensure you're logging the crontab's Unix command.
* * * * * php -q /home/<username>/public_html/cron.php; ls -la >>/var/log/cronrun 2>&1
This will capture anything from the Unix command.
A couple of additional hints: Write out the environment variables by issuing the command set with no parameters. And get the shell to echo each command with the set -x command. At the top of your script issue;
set
set -x
For cPanel, you may want to test curl (in case it's installed on your server):
curl --silent --compressed http://www.your-domain.com/cron.php
So it should look similar to: http://grabilla.com/0450d-93d93a32-02ab-457c-ac1c-d2883552a940.html#
You may also want to try removing the -q from your command and see if it helps.
* * * * * php /home/<username>/public_html/cron.php
*/1 * * * * /usr/bin/php -q /home//public_html/cron.php
Add the above line to the crontab file and run it . It will add a cronjob every minute
I am setting my cronjob as:
*/5 * * * * /usr/local/lib/php /home/..app/webroot/cron_dispatcher.php /devices/checkForAlert
whereas in checkForAlert function of devices controller i’ve just printed ‘hi’ but mail from cronjob only contains this
/bin/sh: /usr/local/lib/php: is a directory
Can you please tell me that is going wrong here…
To have a portable solution you can use env :
*/5 * * * * /usr/bin/env php /home/..app/webroot/cron_dispatcher.php /devices/checkForAlert
/usr/local/lib/php: is a directory
You have provided the path to a directory called php, rather than the php binary.
Try typing whereis php and replacing the above path with the one returned:
> whereis php
php: /usr/bin/php /usr/share/man/man1/php.1.gz
For example, that would be /usr/bin/php in the above output.
