I would like to introduce changi, who will help with server administration hello all heya changi :) hi amette I fear the account validation on sysadm.tw.o doesn't work correctly... marclaporte had problems.. ... I tried it now - did you get an e-mail? otherwise we need to activate your account manually.. no, i don't You've got a mail :) :) thx, i now have access great, cool :) then I worked after all ( I was just on the phone and didn't do anything about the login... ;) ) pretty cool ok, I put you now in the sysadm-group, so you should see what I wrote so far ok will see that later ok amette; pretty cool just to know, what operating system is running for dev and doc ? changi|away: it's Gentoo amette: ok, don't know this OS, (i work on debian) but if you need any help just ask cool - do you have an SSH-key? So I can give you login to the machines. then you can look around and become familiar with it yes have one cool, just paste it here or so ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA25JRqquGB9ZU5i+rnBgP1D/KS4VqlMc6/OcTSDbg0NLJshKVJgZ3eXo8nR8GVs39l0dcpnBX7BFiqrSWv7Fx62fm58FXl7/htVJ1wjBKvgahqyKpjlXvo5gOsBCNe8PYgsqN8Y3y3B1xd+3WdF7e5N3o5t91kKguFdiR8huDSw1qwDoQL4xzFj5wj2GydXZWLYuBxPxLptIOY7kuFL3M2648mFIn7k23SPrkHK5ss2G5O6s1dDMRVnp17JQBWpfQzf+AlKy8a9y/7C2JaQ896TeMLFXavjvcL+f0TnDBvtGPA+CSLcvPtfrJIY+SJ5T9DqRa/j0O7jCjhLp/oahFKQ== changi@sga ok, you should be able to log in to dev/doc and db0.tw.o now... ... db0.tw.o doesn't have a dns-entry, I think... ... 78.46.199.149 it is thinking of making it a completely private machine... dunno... let's see next year about that it ask me a password huh? did you put it in authorized ? just pasted it in strange, i use this key to connect to info.two so, yeah hmmm, tried other hosts? dev/doc? which user should i use ? ah, right - root it works great :) don't you think it's a little bit dangerous to put root access direct on the internet :) yes, I do think so :) there's a private network, which I planned to use for that... ... I haven't done much after putting the machines up.. I have planned that for the next month, after I found a final place to live in... ;) marc tell me about that ... so until then I'm totally open for any good suggestions how to do it.. :) ah, ok, cool you're in berlin ?? yup, just moved here three weeks ago ok you're in strasbourg? yes ok, cool, no problem with timezones then... ;) yes it is, so, just have a look around the machines, hang out here and feel free to ask.. .. I'm always online, but not always there - but ping me and I read back my chatlogs! no problem just to understand the architecture, it a single machine with xen and 3 or more virtual machine ? it is a single machine running Xen, with 3 DomUs there is one more DomU, which is the management machine - it compiles upgrades, does NIS and NFS and it runs the nagios in the topic yes talking about that, the main page of the site is very cool (It Work's) on which server did nagios run ? hehehe :P man.tikiwiki.org wait, I put your key there, too... a lot of server :) ah, nope, right, I don't have login there... hehe, yeah, it was planned to make this scalable - so that you rent another server and can duplicate a webserver there and manage it from the same management-server.. ... eventually it gets complex... ;) so who manage the nagios srv ? ... but I think it's still pretty simple overall - it really just does the necessary (when taking the scalability into account). currently me - and Avonsys has another one, where we don't have access... ... monitoring of the other tiki-sites should be in this nagios, too... .. we need some way to coordinate our efforts though.. It's a little old version :) ehm, yeah - I got login there... just no authorized_keys yet - try now.. ;) yeah, I didn't want to go to 3 immediately - it was just fresh, when I set that nagios up but so far there are also no interesting features in 3, that would make the upgrade necessary I use the nagios3 for 9 month, and it's pretty cool :) group management and look and feel nice man.two has got no DNS ah, ok, that can be... man0.tw.o or 78.46.199.144 or manager.tw.o I only access it from the hypervisor nice gentoo has the same folder structure than debian yeah, even a bit stricter to the FHS, why I like it more Will be easy to accomodate :) think so :) I use git in the / directory to track configuration changes... ... there's currently lots uncommitted, when you look at git-status - was a stressy time.. ;) using git to track modification. Tricky system :) yeah, I meanwhile think that hg would have been the better choice... ... still gives you all the power of distributing configurations to machines, etc but easier to handle... have you heard about puppet ? no, sounds unfamiliar http://reductivelabs.com/products/puppet pretty cool system :) I use it to make DRP on my debian server Disaster Recovery? Yes sir ok :) but we will see that later sounds like a pretty mighty system - gotta have a look at it :) yep, right :) i would like to draw a system architecture of your installation there's also a very nice and lightweight system working on top of rsync, which google uses... don't recall the name.. yeah, sure - I'd love that! :) I'll start and send it to you to make correction I have a very simple drawing in the slides, where I presented this setup... is that ok for you yes, sure which software do you use for it? the software you want heh, ok - as long as it's open source, I'm happy, I guess... ;) kiwio, oodraw, gimp I used oodraw out of necessity, to make this quickly: http://conf.phpquebec.com/slides/2009/The-virtualized-server-infrastructure-of-the-TikiWiki-community-phpquebec_2009.pdf I think some vector oriented would be good?! dia or so? ok for DIA ok, cool just to know, is there a possibility to have one of this server on debian or ubuntu OS ? yeah, that would be possible ok good been thinking of moving over to Debian afterwards... dunno, if others like to maintain Gentoo systems... but for now I like Gentoo because of it's flexibility, I can play very freely with what I want to do we could discuss of what you need and I think all your doing with Gentoo is possible with a light debian :) yeah, I think so, too - but on debian I would have already installed a complete X ;) not necessary here - I like that :) On my point of view, X is not necessary Why would you installed a complete X ? yeah, it shouldn't be - but it's very often a dependency, when you install a server with debian - on Gentoo, I just set the USE-flag to "-X" and it doesn't do that part to help for configuration ? I manage over 30 linux debian with plainty of software ( apache, mysql, nagios, cacti, .... and more) with no X dependency :) I used Debian in my former job and it was nice and easy to work with it in a team, but sometimes I missed my Gentoo flexibility ;) lol oh, with cacti I would have expected the dependency of rrdtool and that rrdtool would pull in Xlibs, which then pull in the complete X-libraries... ;) I gotta run to the grocery store... bbl you're right libX11 :) but it's just client side :) hehe, well... fair enough.. ;) do you know screen ? amette : what is the ip address of db0.two ? changi|painting: yeah, and I don't know how any sysadmin can work without it :) ip of db0 --^ 78.46.199.149 ok, now for the cooking :) sysadmin.two access ? http://changi67.isa-geek.org/Archi.two.png that's a start
