Hi,

I have cron jobs set up on my server to run two shell scripts for backing up a wordpress site. The script that backs up the files is working but the one that is supposed to back up the db is not.

I will pay someone who know shell scripting language, for the time it takes to look at the code and fix it.

Please send me a pm if interested and available and if you have a bonafide company.

Thanks,

Why not set a cron job to dump the database to a file as well? (Preferably outside your web root). It'd be a one-liner.

You could also have a look at rsnapshot, which is simple, free and gives you snapshots/versioning of your file system and/or database.

I did. That's the script that's not working. I need someone to fix it so it does.

Have you looked for a good WP extension to handle this for you?

You mean a plug in? Yes, I'm using one now that was free, and looking at another one with better features that I will have to pay for. In the meantime I'd like to get both cron jobs working. I feel sure the code fix would take 5 minutes for someone who knows what they are doing.

Plugins are great but they constantly have to be updated and sometimes they break.

I do scripting (but not coding).

Do you get any error messages?

Would you be able to post the script here so we'll be able to take a peak?

Check: Crontab, which user is running the script (and that it has privileges to access the database), script execute privileges / ownership. After this you can try to rung the script on command line with the correct user.. this might bring out some error messages.

--

So first check that the crontab entry is in order

crontab -l -u username_which_is_runnign_the_script #This is probably the database user

Then check that the script permissions are ok.

ls -l /path/to/the/script.sh

It's possible that the script simply lacks execute privileges. You can add some

chmod 755 /path/to/the/script.sh

And then try to run in manually

/path/to/the/script.sh

Okay, here is the file back up script, which works fine, where public html is the root directory .

#!/bin/sh

backup_files="/home/eggmeng/public_html"

dest="/home/eggmeng/public_html/shell-backups"

day=$(date +%A)

host=$(hostname -s)

archive_file="$host-$day.tgz"

tar czf $dest/$archive_file $backup_files

And here is the db backup script which doesn't work.

#!/bin/bash

PATH=/usr/sbin:/sbin:/bin:/usr/bin

user="[db_name_goes_here]"

pass="[db-password_goes_here]"

host="localhost"

sub="$(date +"%Y-%m-%d")"

dest="/home/eggmeng/public_html/shell-backups"

mdb="$dest/db/$sub"

if [ ! -d $mdb ]

then

mkdir -p $mdb >/dev/null 2>&1 && echo "Directory $mdb created." || echo "Error: Failed to create $mdb directory."

else

echo "Error: $mdb directory exits!"

fi

now="$(date +"%Y-%m-%d_%H-%M-%S")"

file=""

dbs="$(mysql -u $user -h $host -p$pass -Bse 'show databases')"

for db in $dbs

do

file="$mdb/$db.$now.sql.gz"

mysqldump -u $user -h $host -p$pass --complete-insert $db | gzip -9 > $file

echo "Backup $file.....DONE"

done

find $dest/db/ -maxdepth 1 -type d -mtime +6 -exec echo "Removing Directory => {}" \; -exec rm -rf "{}" \;

For the first, you need to replace the ">" with ">" and "&" with "&" on your script. The second last line does not matter, just an beauty thing, but these lines will make the script fail:

mkdir -p $mdb >/dev/null 2>&1 && echo "Directory $mdb created." || echo "Error: Failed to create $mdb directory."

--> mkdir -p $mdb > /dev/null 2>&1 && echo "Directory $mdb created." || echo "Error: Failed to create $mdb directory."

mysqldump -u $user -h $host -p$pass --complete-insert $db | gzip -9 > $file

--> mysqldump -u $user -h $host -p$pass --complete-insert $db | gzip -9 > $file

After modifications try to run it manually and report the possible error messages.

Thanks ENC. I made the mods, replaced the script and I'm getting this email notification and the same result as before, wherein a folder named with today's date is created inside another folder named DB. But the folder is empty.

Looks like the script is being denied access to the db, doesn't it?

That looks like it. Your username is '1' ? Could you double check that one as well as the password.

Then try on the command line if you can connect to the database

mysql -u user_name_here -pthe_password_for_the_username

Both the user name and the pw match exactly what I have in the config file. I copied and pasted them from there. So I don't understand why this error message is returning "1".

Here is more or less what the user name looks like in the script:

user="[eggmeng_alphanumericstring1]"

Ah. Remove the "[" "]" marks from both this one as well as from the password

--> user="eggmeng_alphanumericstring1"

You are a gentleman and a scholar sir.

I drink to success, and to your health!

Great to hear it works!

Btw. Last night I drunk for the health. Today I'm feeling that the effects were only temporary. Memory corrupted, system not in good health, but the core was not dumped!

Yes, avoiding fatal errors is the main thing.

And thank you.

I love seeing these kinds of conversations here!

Oilinki,

Your answers for Eggmeng a few months ago were so helpful for me, too! Thank you!

I am still getting a couple errors... would you be willing to take a look and see if you find any problems?

THANK YOU!!!!!

ask at puppy forum theres vastly more people familiar there. #puppylinux chat sometimes has action for quick questions. just one way to get there
