One question only... why was mydns imported into ISPconfig 3, instead of bind like old versions ? For example... this crapy program is taking way too much cpu usage by doing absolutely nothing. I didn't even put server online and it's already consuming 9% of CPU usage... Here is just an example: I wonder how this thing will perform when i put like 100+ pages on it... it'll go nuts probably. I dont think changing defacto best dns service as bind is good idea, but ok please tell your opinion please.
not sure why but here is what i think due to the MyDNS use an SQL backend to handle the DNS recoards and you can add / change them on the fly without needing to restart the DNS server but its odd that mydns is runing at an high level on your system there i use it for my DNS server on my network for privte DNS and access to outside my LAN DNS lookups without a problem / any CPU being used maybe restart the system or do an install in VM and see how its goes see if it is using less CPU
Seems to be a problem with your server only. We are using mydns on several heavy used dns servers and the load is very low.
You can configure caching in the MyDNS configuration. That might decrease your load. Also, you can optimize MySQL (e.g. enable the query cache).
Well as i dont have any zone in mydns yet, nor i have port open for dns, this means the daemon is idling in background doing nothing. That's the thing. So enabling cache or mysql cache wouldn't really help out at all i think. But ok i'll wait till repositories of centos 5.2 bring new mydns port and i'll update it and see if that fixes the issue. Else it's just very unoptimized dns daemon i guess...
Oh yes and here is munin graph of cpu usage... before you can see there was all the time cpu usage by "system"... and after i turned off "mydns" (i'll probably use bind for now), you can see how much system usage dropped out. Almost to zero... http://www.shrani.si/?3N/6H/PPPsIVa/localhost-cpu-day.png Best regards. Thanks for the replies though.
From a freshly installed ispconfig 3 server without load on the dns server: Code: ps aux | grep mydns USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND nobody 11622 0.0 0.0 4792 1328 ?

mydns-1.2.8.15.tar.gz I was following the install txt file in the ispconfig distro. I just went though and see they have realeased up to...mydns-1.2.8.26.tar.gz. I note though that ispconfig install was done after the installation of mydns which means it is possible that isconfig did some configuration and setup of mydns after it was installed? If so how can I safely upgrade to the latest version there to see if that solves the issues, and still maintain the integration of mydns and the ispconfig panel. Thanks.
Can you see my question above before I attempt this. I will do the install the same way as i did the first install for mydns? That's all? I dont have to worry about doing anything fancy to maintain its integration with isconfig?
I've upgrade MyDns to .26 ... still the same problem...it starts off good then after a while it shoots up and maintins 90+ cpu usuage until i stop the dns service. Which leads to system state going back to normal. How widely has this been beta tested and will there be a deluge or bug reports when this comes out of rc and is more widely used. Its a fresh install of ubuntu 8.04 + ispconfig 3.0.0.9 rc2 Is there a way to uninstall safely and integrate bind into ispconfig? Some help is needed here if possible.
More then 10 000 installations and I use it also in production on a few of my own servers without any problem.
Is there a way to replace it with bind. will it mess up my ispconfig install. Will i be still able to use dns wizard with bind?
Bind is not supported by ISPconfig 3. As mydns works fine in thousands of installations there must be a problem with your specific install.
I was looking at this page http://www.howtoforge.com/installing-mydns-mydnsconfig-centos-5.1-p2 And saw this... Code: Finally, we need to fix the system startup links for MyDNS. MyDNS depends on MySQL, so MyDNS must start after MySQL has started, otherwise it will fail. The default startup links for MyDNS make it start before MySQL which is wrong, so we fix this as follows: cd /etc/rc.d/rc3.d mv S52mydns S99mydns cd /etc/rc.d/rc4.d mv S52mydns S99mydns cd /etc/rc.d/rc5.d mv S52mydns S99mydns MySQL uses the startup links S64mysql, so renaming the MyDNS startup links from S52mydns to S99mydns makes sure that MyDNS starts after MySQL. I looked into my rc* directories and saw that rc0.d. rc1.d and rc6.d has mydns coming before mysql (which i guess means it starts before mysql?) BUT in rc2.d to rc2.5 it starts very close after. Do you think this could be a problem....I am not to sure how to address rc0, rc1 and rc6 as the guy above talks only about rc3, rc4 and rc5. What do your rc* folder arrangement looks like. Would rc0,1,6 cause a problem with mydns comming before mysql and if so what should i do in my context.

Do you use ubuntu or centos? Above you said that you use ubuntu and now you link to a centos installation.
