i find on the certain time,

and the io and load will become very high,
after the time point,
all the io and load with be smoth,
so,i wonder if any Cron job has been add (by certain account) to run something,
We're running on Linux/Apache/MySQL/RoR and have a number of cron jobs that run throughout the day on our server. We've been noticing lately that at certain times of the day the site becomes really slow. When I'm online with my engineers I can mention this to them and they can check and see and say "Oh yeah, it's job XYZ that's spiking the server load."
That's great but much of the time when I notice the sluggishness my developers are offline (we're in different time zones). I'm wondering if there's a fairly easy way to track this when they're not online so we can say "Yup, last night at 10 PM your time when you noticed that it was job ABC." There has to be something that allows you to do this right?
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.
Does anyone know how I can find a host like this?
I have a number of PHP scripts that I would like to automatically run daily at midnight. I am currently running a VPS server but have no idea how to achieve this. I do have webmin on my sever but am unsure of what command I need to run.

My /etc/crontab file is as follows.
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
Here are the contents of a sample user cron file.
MAILTO="USER"
10 4 * * * php -q -f /home/USER/public_html/tools/updtransfers.php /home/USER/public_html >/dev/null 2>&1
10 5 * * * php -q -f /home/USER/public_html/tools/updateexp.php /home/USER/public_html >/dev/null 2>&1

I've checked my logs, and I can find no errors anywhere. When I run the commands manually via SSH, they work perfectly, they simply are not being run automatically the way they are supposed to be.
I have checked, and the crond service is running. I have tried restarting it, but it seams to have no affect. I really have no idea what the issue is. The only thing I seam to have found at one point, was the possibility that the files within the /etc/cron.d directory might be CHMOD'ed wrong, but I haven't found anything to confirm this either way.

Is there any software which would control cron jobs? I've a problem with cpu load where some customers are running more than enough of them at the same time.
Is there any software which would be able to:
If there are more than x crons running at the same time, put others in queue and execute after there are no more than x-1 are running?
how to set cron jobs in window....
View 6 Replies View RelatedI have a new dedicated server and am trying to set up a cron job via CPanel on on of my accounts (we'll call it "abc" account).
In the Cron job area, where it asks for the command to run, I enter this:
/home/abc/public_html/forum/class/sendnotice.php
But when the job runs, it doesn't seem to be executing the .php file. Instead, I get stuff like this via email:
/home/acb/public_html/forum/class/sendnotice.php: line 1: ?php: No such file or directory
/home/abc/public_html/forum/class/sendnotice.php: line 2: ////////////////////////////: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 3: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 4: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 5: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 6: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 7: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 8: //: is a directory
/home/abc/public_html/forum/class/sendnotice.php: line 9: //: is a directory
So it is as if the cron job is reading each line of the .php file instead of just running it. Am I doing something wrong in setting up the cron job to run that file or could it be a configuration issue with the new server?
How I can set CronJobs? Have never to it before.
Here is what i have from developer:

I need a reliable, free host where I can run wget on a URL (less than 1k) every 10 minutes via a cron job.
Can anyone reccommend anything?
I have a customer billing system.
I would like crons to run at midnight so that the invoices are on schedule and have the right dates etc.
My server is overseas and my time is plus 14 hrs here.
I have set my software up to plus 14 hrs time difference also.
What should I set my crons to?
How do you insert variables in cron jobs? e.g. the current date.
Let's say I want to back up a file and append the date to it.
0 0 * * * cp /some/file.txt /some/outputfile_[DATE].txt >/dev/null
(note that I'm not sure the cp will actually work like that, it's just an example)
Where outputfile_[DATE].txt has the date in it.
Are there variables cron can use for date, hour, minute, etc.?
i need information about this option 'Check /etc/cron.daily/logrotate for /tmp noexec workaround', there are in the server check, of the csf test, someone can explain to me about this function? should do it?
the actually state is 'warning'.
i just got a 2nd server
i had a problem at the beginning that i had to reload
so i think the tech forgot to add my other ips to my network card configs
i remember layeredtech once reloaded my server and the same problem happend so they advised me to add it to a config file in my server
I had csf firewall installed, and due to my own stupidity, attempted to login with the wrong password one too many times, which added my IP to iptables, locking me out. I had to SSH into a linux box at school, and then ssh into my server to stop the iptables service so I could get into my server.
I removed every trace of my IP that I could find in csf, but sometime in the middle of the night, iptables reloads some rules from somewhere that blocks me again. I also tried doing iptables -F to clear all rules, but again, sometime in the middle of the night, rules are reloaded and I get blocked. I even uninstalled csf to no avail. I just want to remove my IP once and for all.
When I add a new site via New Account in WHM and once the domain resolves, the cPanel 'Great Success' page shows. I have verified the site is resolving properly.
This is a brand new installation and the only changes I have made is I updated apache via WHM.
My fedora server is running apf firewall. When I turn it off, clients can connect.
When I turn it on, it says MSG: Contacting Server.
I have already added ports 6100 and 3784 to /etc/apf/conf.apf by adding the ports to the lines, EG_TCP_CPORTS, EG_UDP_CPORTS, IG_TCP_CPORTS, and IG_UDP_CPORTS
and restarted the service.
Is there any additional ports I need to add?
(I've uploaded my conf.apf file)
I've been having an issue with one of my sites were someone has been adding malicious code to the index file. I don't know what has been compromised and am looking for a way to stop this.
I have a dedicated server have already upgraded MySQL to the latest version as I though that might work but it hasn't.
