synchronizing multiple servers

[lnxcode]

You should be able to set this up in the root cron to do like every 30 mins:

*/30 * * * /etc/sync.sh

Make a file with the below code in it (you can use notepad and save it as sync.sh)

cd /home/user/ &&
wget -q -nH --mirror ftp://user:pass@host/public_html/ &&
chown user:user public_html/ -R &&
chmod 750 public_html/

User = FTP username
Pass = Password for FTP
Host = IP or Hostname of your old account (where it will pull data from).

upload it via SCP or wget to /etc/ Leave the ownership as root:root

Is this used to do backup mirror servers from the very large sites? So if one DC goes down, the backup NS3 and NS4 slots pick up and serve the page properly?

Interesting

[lnxcode]

Well its used basically for mirror multiple servers across a string so if you have a cluster such as:

Server 1
Server 2
Server 3

But you dont want to update all 3 with the changes, what you can do is use the above script to copy everything from Server 1 to all the others, by having them sync every 30 mins +/-.

So result 30 mins later would be that all would have the same files, content

Very cool. I love it!

This way works a little better I learned:

Rsync copying files.
