Cron Job Not Working, Restart Services
Jan 1, 2008I'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...?

Howto: Automatically Verify Cron / Crond Is Running And Restart If Not
May 30, 2005This one's pretty simple really, but given the fact that I'm constantly running into crond stops with CPanel servers (no clue why, or where, but it's happening), I'll post this here. If it helps someone, then great, if not, hey, no worries.
Firstly, login as root to your server through ssh, however you usually do .
Next, the script (we'll call it /bin/croncheck.sh). Use whatever editor you choose to create the file.
#!/bin/bash .......

Mysql Auto Restart
Dec 5, 2008Is anyone experiencing that cpanel automatically restarts mysql at 2AM?
I'm curious is that new feature or something has gone wrong?
This has started after cpanel upgrade mysql to 5.0.67 version.
I'm not so good with cpanel so please can somebody tell me where cpanel holds its crons?
I cannot find nothing in /etc/cron.* or in cron -l, and I want to turn this option off.

MySQL Restart On CentOS - Chown
Sep 18, 2007I have a lot of tables, being that I host multi forums. One thing I noticed when doing a mysql start up or restart is that it takes at least 15 minutes to do it. The server isn't bad, it's a Pentium D with 3GB of RAM and it runs perfectly fine. What I noticed is that after I do an SQL restart, I checked "top." The command that was running is "chown" and it sat at the top of the list, and kept going. Until finally mysql started and it stopped.
I imagine that all of the files in the data folder are being CHOWNed... and that's why it takes forever. If this is the case, how can I stop this, if at all? I don't see why they need to be CHOWNed?

Backup MySQL Databases By Cron
Apr 1, 2007how to backup MySQL databases by cron and have the backups sent to you by email, or have them uploaded by FTP. It is based on a script I found at another website though I can confirm it is fully working.
Change the commented variables in the following file and save it as backup.sh:
Code:
#!/bin/sh
# This script will backup one or more mySQL databases
# and then optionally email them and/or FTP them
# This script will create a different backup file for each database by day of the week
# i.e. 1-dbname1.sql.gz for database=dbname1 on Monday (day=1)
# This is a trick so that you never have more than 7 days worth of backups on your FTP server.
# as the weeks rotate, the files from the same day of the prev week are overwritten.
#/bin/sh /home/user/directory/scriptname.sh > /dev/null

Upload backup.sh to your server, to any directory you want. A directory which is not web-accessible will stop your login information being seen by just anyone .
You should chmod the file to 777:
Code:
chmod 777 backup.sh
If you uploaded this file from a Windows machine you will need to convert the file to Unix format. You should run the following command by SSH in the appropriate directory:
Code:
dos2unix backup.sh
If you don't have dos2unix installed, you can install it using yum if you have that:
Code:
yum install dos2unix
If you don't have yum, get it here.
You may want to test the script at this point to make sure it's doing what you want it to. Change to the appropriate directory and run this command:
Code:
./backup.sh
Once you're happy with it, enter it into the crontab to run daily (or whenever you want). Cron jobs vary a lot depending on the configuration of your system, so check Google for how to do it on your system. The command you will need to run by cron is:
Code:
/path/to/file/backup.sh

Is It Possible To Create A Cron To Backup Mysql Data Daily

Host Recommendation (Req: PHP5, MySQL, CRON, Mass-Email)
Sep 1, 2009any hosts that can provide the following:
PHP5.3 +
MySQL
CRON (to run daily/weekly scripts at a certain time)
Mass Email. The scripts will send emails to a number of users(between 10-100 at first, but may grow) and this will be done daily and weekly.
In the past, I've tended to go with SupaNames or FastHosts but looking at their solutions for this, it's not quite right for my requirements.
