How to set cron in linux server? - php

Hi i have created a birthday notification. My Cron URL is http://dev.raddyx.in/bday/birthday.php
I want to set cron run in every 24 hour but i am unable to run in the Linux server.
Check my command:-
50 10 * * * curl -s -o /dev/null http://dev.raddyx.in/bday/birthday.php
Please help me how to set cron in Linux server?

Are you entering this in /etc/crontab? If so, then you will also need to specify the user that the command is to run as, in the sixth field:
50 10 * * * root curl -s -o /dev/null http://dev.raddyx.in/bday/birthday.php
You may want to look in /var/log/cron for some leads on the problem.

Check the CURL is available or not otherwise you can use wget to execute the request
This will execute every 10:50. You can try this also
50 10 * * * /usr/bin/wget -O- http://dev.raddyx.in/bday/birthday.php >> /dev/null
This will dump your errors into this cronerror.txt file
59 10 * * * /usr/bin/wget -q /var/www/<your log folder path>/cronerror.txt http://dev.raddyx.in/bday/birthday.php

Why my crontab not working using wget command?

When i run my url https://localhost/panel/index.php?m=user_games&p=check_expire by using chrome the code is run and shutting down the server when expier.
But when i need to run this as a crontab using this command:
* * * * * * wget -q --spider "https://localhost/panel/index.php?m=user_games&p=check_expire"
nothing happend, why?
Seem the crontab not run, because you define wrong crontab command. You put six *, as I know we just need five *. Please try like this
* * * * * wget -q --spider "https://localhost/panel/index.php?m=user_games&p=check_expire"
To make sure your crontab run, please create log when wget executed.

Running PHP file using crontab

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

Cronjob not executing php?

I want to run a .php every 10 min with a cron job on Ubuntu.
This is my crontab:
*/10 * * * * php -f /var/www/html/gapi/src/test2.php >/dev/null 2>&1
And this is in the log file:
CRON[9994]: (root) CMD (php -f /var/www/html/gapi/src/test2.php >/dev/null 2>&1)
In this php is an api call, and I can see the api calls live at the dashboard of the api provider, so I know the php is not running every 10 mins.
I set the file permission to 755, what else can I do to make it work?
Updated Crontab:
*/10 * * * * php -f /var/www/html/gapi/src/test2.php
Try requesting the file through your web server rather than calling the script via the command line PHP interpreter.
*/10 * * * * wget -q -O /dev/null http://localhost/gapi/src/test2.php
(-q to suppress output, -O /dev/null to redirect file output so it doesn't save it)
or using curl instead:
*/10 * * * * curl --silent http://localhost/gapi/src/test2.php
The URL will depend on how your server is set up - you say it works through your browser at the moment so just use the same URL in the cron file.

cronjob is not working Linux

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
