I have a dedicated CentOS 4.5 Server. However, as you can probably guess I am new to linux and managing a server...
Anyway, beginning of this month my crons quit working, I still receive emails as if they are ran but I can't get the scripts to actually execute.
I have not touched the crontabs or anything prior to them not working, they simply quit working... I did not notice immediatly they did not work, I am guessing that it was around the time of which I rebuilt apache to a new version of PHP. Today I tried changing them to "php path/to/script.php" and I also tried "path/to/php /path/to/script.php", neither worked.
Any ideas or suggestions as to how I can fix this?
I'm needing some info i have been pulling my hair out for hours trying to get some cronjobs lined up i started out with knowing nothing about it and i'm a little better off now i got the cron running but the commands aren't executing so maybe someone can help me figure out why i would greatly appreciate it
Here's The deal I telnetted in set the following crontab ...
I have a slight problem with a cron job I have setup.
I wanted to save a copy of iptables every hour to a folder, so I created a script... here it is:
Code: varDate=`date +%y%m%d` varTime=`date +%H%M`
filename="IPtablesBackup-$varDate-$varTime" iptables-save -c > /etc/IPtablesBackup/$filename and called is Backup-Script.sh
Now if I just execute the script will in root ./Backup-Script.sh I get a new file with the correct filename and iptables info is saved ! Great ! So then I thought, how can I setup this automatically every hour.
Which leads me on to my problem. I inputted "crontab -e" added this line
Code: 59 * * * * /etc/IPtablesBackup/Backup-Script.sh The problem is the script is run, I know because it creates a new file with the correct time and date, however the file is empty?
I have set Backup-Script.sh to 777 and owner and group are both root?
I did not realize the significance of the Apache sub-forum. I thought perhaps this would be a more general Server management query, but I realize now I should have posted in Apache forum.
I have been banging my head against the wall for the last couple of days trying to get cron jobs working. It's actually making me quite depressed, a lot of people are waiting on me to get this working, and for the life of me I see no light. I'm not a stupid person, i'm a PHP developer, and have some linux skills. This is the single most annoying issue I have had to deal with simply because I cannot find any troubleshooting methods to my issue.
I have tried every different combination of command under the sun and I cannot get any sign that the cron is running the commands.
I own a "virtual" dedicated server with a hosting company, I have full root access. Linux / Apache
The script file is a PHP file which simply mail() an email saying that cron is working, I am yet to receive this mail that was executed by cron.
I have ensured there are no errors in this simple PHP file, I have executed the script from the shell and all is well there..
So, firstly I tried to setup the cron table from CPanel, on the account where the script resides.
I used the following command combinations: Code: 0-59 * * * * /usr/local/bin/php /home/username/public_html/cron.php 0-59 * * * * php -q /home/username/public_html/cron.php 0-59 * * * * php /home/username/public_html/cron.php 0-59 * * * * cd "/home/username/public_html/"; php cron.php 0-59 * * * * wget [url] with time combinations of: * * * * * to get the command to be executed evey minute, for testing purposes.
All these commands work fine when executed through the shell.
I set the mail address for cron output to be my mail address also.
I do not get any mail from cpanel with an overview of the cron executions.
I then gave up trying to get cron to work on that account, and decided to go root.
I logged into the shell via root, checked the cron table for root. I edited the root cron table (that contains commands for various cpanel scripts etc) to include a command to execute the php script, even with the script residing on the root directory.
I also added MAILTO="myemail@email.com" to the first line of the cron table.
I do not get any emails of the cron actions.
How can I check if the cron scheduler is working when I get no sign that the cron commands are being executed, and when I do not receive any cron emails? What methods are there for me to troubleshoot this issue?
Could it be possible that cron shedular is not active on my server?
I have lurked the net with great detail to find any method to troubleshoot my issue, and all the related pages I find are to do with troubleshooting the commands. I know my commands are fine, there is some other issue here.
I'm having a bit of trouble with one cron job that doesn't seem to work.
I have others scripts that run hourly fine. However this one does not.
The script:
restart_monitoring.sh
Code: #!/bin/bash service iptables stop service iptables start /root/bandwidth_rules.sh /root/portforward_config.sh exit The two scripts at the end just load a lot of iptables rules back in.
The cron job should run hourly (59th minute)
The cron job entry
Code: 59 * * * * /root/restart_monitoring.sh I have restart crond to enable the new job, still doesn't run.
The job is to restart iptables, thus flushing all rules that I have running, then reloading them. I have figured out the problem to be with the "service iptables stop/start" command, it doesn't seem to like doing this...?
How do I make sure that there are cron jobs running on my cPanel server? I have root access, etc...just not sure why my crons aren't running. Nothing weird going on.
i have setup fresh Centos 6.5 with Plesk Pannel 12.0.18. When i execute the attached command from the console, i get it work, some posts are auto created within wordpress. When i enter the attached command within Plesk (Tools / Settings - Taskmanager - root New Task, the command is not executed...
I have a domain with a few forwarding email accounts that forward to mac.com email accounts... for some reason every once in a while these accounts stop working...
This is the error I get when I email to that account:

I have root access to a server. Is it possible to create a cron that would restart my ftp and http server every so often. Like once a week or somthing. If so how would i do it?
i have had a problem for some time now, regarding my CRON jobs. I am trying to download a large amount of data from ebay (through their API, totally legal and aboveboard) using php, but my CRONjob times out.
I have tried resetting the timeout variable, but then it exceeds the maximum filesize SO, my question: is there any way to have a script run as a CRON job, and wen it is complete, call another script?
Hey everyone, my friend's dad is looking for a web host that will allow his cron jobs to run every second. Most hosts apparently dont allow cron jobs faster than 5 seconds apart.
How often a host can run cron jobs isn't really advertised on their sites so I'm having a bit of trouble finding a host. I've resorted to just sending emails to sales addresses asking about it.
VPS isn't rebooting by itself when it goes down. Anyone has any program/script that monitors heartbeat of the server? Like when it goes down, the program will automatically reboots the system. I know there's such a script out there but I forgot what it called.
I have heard mixed reports and can't find any good info. Personally i've run a cronjob for up to 6 minutes, but as my best method was sending myself emails through php, its not exactly a highly accurate testing method.
On the same note, what would happen if one cronjob is running a php script for over 10 minutes, then another cron job starts on the same script, before the first one has finished?
I have my own server. I create php file for adding cronjobs. I checked /etc/cron.deny and /etc/cron.allow. both of them is empty so no problem. I execute the php script but nothing : I check with crontab -u user l and it told me no cronjobs for that user. When I access as root from ssh and try teh same command, it works fine. I don't understand how to fix that.
I have a bit of a strange problem, I have an rsync command setup in the servers crontab and from the cron log it show it ran the command but the files don't copy to the backup server. If I take the rsync syntax and run it manually all the files copy across with no errors, but I can't figure out why the cronjob doesn't work properly.
I've just noticed that many people may have a free remote cron facility without realising it.
If you have any domains registered with Godaddy, you get free web space that includes a cron facility. It only runs every half hour, but you could set six jobs at 5 min intervals to get an effective 5-minute poll, which is good enough for many purposes. You could use it to check uptime on another site, for example. Has anyone tried this?
