De HOUWER van de Server van het Web DIY Linux - automatiseer uw het gegevensbestandsteunen van MySQL MySQL

Binnen gepost Blog, Koel, DIY Zedomax, DoItYourself!, Onderwijs, Houwer, Linux, Ubuntu, Web, Wordpress door maximum op 10 Februari, 2008 in 5:24 p.m.

O.k., heb ik specifieke servers paarjaren nu in werking gesteld en ik gebruikte om rond met dozen Linux terug in universiteit te knoeien.

Hier is een essentieel automatisch manuscript en een cronbaan u uw steun zult moeten automatisch houden.

Ja, als u een specifieke server krijgt, krijg hun stomme extra $15/month niet voor het steunen van uw gegevensbestand.  (Allen zij doen is maakt manuscripten als dit één en laadt u voor het)

U kunt dit voorbeeld volgen en gaan besteedt dat geld aan troepvoedsel.

Zo allen u moet doen is FTP uw reservedossiers.

Dit is manier dan beter gaand in uw phpMyAdmin en downloadend van de Webinterface aangezien het dossier reeds klaar voor u aan download is.

Here’s how you do it:

1) Make a new file called backup.sh in your home directory. 2) Use the following syntax:

mysqldump -u[USERNAME] -p[PASSWORD] –opt [DATABASE NAME] > /root/backup/DATABASE1.sql

Here’s an example backup.sh file if you had 2 databases:

mysqldump -uUser1 -pPassword1 --opt Database1 > /root/backup/Database1.sql
mysqldump -uUser2 -pPassword2 --opt Database2 > /root/backup/Database2.sql
tar cvf /root/backup/sqlbackup.tar /root/backup/*

You can test your script by typing this:

sh backup.sh

(The mysqldump will overwrite the older file if you run this more than once)

3) If everything is working good, now you can put that script to be run once a day in your cron job.

For Fedora Core, you can edit this file /etc/cron.d/sa-update

Add the following line:

10 3 * * * root sh /root/backup/backup.sh

This will execute the script once a day at 3:10AM.

Now simply download one tar ball file whenever you feel like backing up your database.

You can probably change this a little bit and use it for many other things like backing up all your files too. (which I do)

If you have multiple servers like me, you can also automate your scripts to download backup databases to each server. That keeps things real redundant in case of server failure.

To further automate the process of backing up, you should set up a LOCAL cron job that downloads the file to your computer.

Which is just as easy…. all ya do fetch the remote file:

wget ftp://Username:Password@www.yoursite.com/backup/sqlbackup.tar

Cool script.

I’ve always used a software product to backup my DBs - it was something like database backup generator.

You set it to run daily and it’ll back up, email you a download link, and also store as many backups as you need.

The thing I liked was that you could restore the DB with one click from the admin panel.
