Server Move - Is There A Way To Setup DNS To Show A Backup Site / Message
Jun 25, 2009
The data centre which I use, is moving all collacated servers to a brand new data centre next week, which will mean a two hour downtime for each of my servers and customer websites.
At the moment my servers utilise two nameservers on seperate servers and when the move happens all websites will be offline with an ugly error message to any visitors.
Does anyone know a good way to setup a page which would be displayed if the web server was down? I am using MS DNS.
My thoughts so far is
1. Setup a 3rd nameserver which is off site from the data centre.
2. Purcahse web hosting / vps for a month on a seperate hosting company
3. Set it up so that it accepts * to a specific IP address in IIS or apache
4. I create an index.php script which gets the host header value sent i.e. [url]and the page then displays a nice maintenace i.e
"We are sorry joeblogs.com is currently down for maintenace, we will be back online shortly".
I think my main question is do I need to setup a 2nd www record in DNS for each site and how do I ensure the 2nd dns (backup record) only gets used when the first website / server is down.

I plan on purchasing a dedicated server to run a few proxy sites. However, i don't have a lot of Linux skills to administrate my own server. But i've always been able to figure stuff out so i feel pretty confident that i can get it going on my own. Anyways, My original idea was to use cPanel to run the web server for the proxy sites however i feel that using cpanel is not a great idea since i also wanted to maximize my servers performance and i hear cPanel can take heavy resources. So anyways, I just wanted to know what some other people here might think and if possible any recommended guides on setting up a linux webserver would also be appreciated as well.

I own a few domains without websites; is it a good idea to show ads on them; do people actually earn anything by displaying ads on empty domains; my current hosting plan doesn't have quota for additional domains so how do I do that without buying a hosting.

I run a large adult vBulletin community with 70,000 members, 1/2 million posts, 186,000 attachments (a lot video), and closing in on 100 million downloads since our start some odd years ago. I've been battling keeping the site up for quite some time, and I am starting to wonder whether we shot too low on the server setup. I figure I would ask the pros here at WHT for some advice.
This is our current setup:
Site server:
Quote:
CPU: Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz
4 Gig ram
250 Gig sata harddrive
Unix FreeBSD 6.2
Apache
MySQL server:
Quote:
CPU: Pentium III/Pentium III Xeon/Celeron (2666.62-MHz 686-class CPU)
Cores per package: 4
4 Gig ram
750 Gig SATA harddrive
Unix FreeBSD 6.4
Apache
Do you think the site would perform better under one server and maybe a more powerful processor? What should I be looking at exactly as far as hardware goes for this type of site. I should note we push about 2.5TB of bandwidth monthly.

I've taken the scalable approach when it comes to servers for my various sites. With shared servers, I never really worried about backup or even hard drives going down. Same goes for VPS. For some reason, when I moved to dedicated servers, I outfitted them with 74GB SATA drives in a RAID setup. My understanding is that it protects me if one drive happens to fail. I've been lucky and haven't had that problem.
I'm at the point now where I'm looking to upgrade from a VPS paying around $75 per month to a dedicated server. I can stand to be down a day if a hard drive goes, if it means $75 a month in savings. My biggest concern would be suggestions on the best way to protect myself in the event of a catastrophe.
Contacted SoftLayer about possibly adding a second server for me and honoring the price I'm paying on my old server.
Finally, both the old and new site are seeing roughly 3,000 visits per day. The server I'm considering is a Clovertown 5320 1.86 dual quadcore, 4GB RAM, RAID, 2 74GB Cheetah drives,100mbps, 2000GB bandwidth. Is this overkill or the right server for the job?

When i do httpd -S i notice one of my sites show with 2 config source. but i just config one file for the site.
for example:
[root@apachesrv ~]# httpd -S | grep devel.site.com
default server devel.site.com (/etc/httpd/sites/000-default.site.com:1)
port 80 namevhost devel.site.com (/etc/httpd/sites/000-default.site.com:1)
port 80 namevhost devel.site.com (/etc/httpd/sites/devel.site.com:1)
the problem is the following, when i do reload and in this moment the config is bind this result, the site is blank.
Why it shows me this.
version of apache
Server version: Apache/2.2.15 (Unix)

I am working on a busy and popular website which has a large amount of database activity - and requires hourly backups of all database data.
At the moment the site is hosted on two servers - one for the front end web server, one for the database.
Both servers are running a RAID HDD system which allows quick swaps of faulty HDDs without data loss.
An hourly full backup of database tables is running which is killing the server when it runs.
ISP has suggested installing a third server to run as a slave to the existing DB server, and hence always hold a duplicated of the live database.
I have a feeling however that this is basically just like having RAID mirroring, but on a different machine - so to solve the problem of a potential dodgy SQL statement wiping out ALL copies of the live database, we'd STILL need hourly backups to run, and hence would still see the major system speed drop each hour at the time of backup.

We have two in-house servers, one is hosting our public web server. The other one was just purchased to host a mirror of the production server (as a backup). The site is protected by an SSL cert... my question is how do i set up the server(s) so if/when the backup server needs to be switched into produciton, the SSL cert will transition flawlessly?
They are both apache 2 servers.

How can I move my site to a new hosting provider and have no downtime for my customers? (My website, webserver, and MySQL database appear to be online at all times).
I have my domain registered at godaddy.com
I have my current host at ************** with dedicated IP
I have my new host at Cartika with shared IP
The domain at godaddy points to:
ns1.**************.biz
ns2.**************.biz
Can I set up my new Cartika name servers to point to my old site's dedicated IP and set TTL at a very low level, and then change the domain at godaddy to point to the new Cartika nameservers?
This way as the change populates, everything is still pointed at my old hosting site.
Then I move my site over to Cartika, and once everything is tested and working, update the Cartika nameservers to point to the Cartika account?

I've been a reseller for 7-8 years now. Just now getting out of the business.
I've "downsized" so that the only sites I have left are either my own little "experiments" or are sites belonging to local non-profits, where...because of a lack of expertise on their part, I'm basically the webmaster.
One of these sites belongs to my church. The site has been up-and-running for, oh, I think somewhere in the realm of 4-5 years now.
In the past two years, we've seen a large increase in the number of exploit attempts on this site. First, there's the never-ending flood of bots... creating user accounts in the forum software and image gallery software.
Then there are the actual hacks. Once, long ago, it was hacked by a pro-Muslim-extremist group. (But it wasn't alone. A ton of sites all over the net were hacked that day. Hacker through up the same pro-Muslim-extremist page on all of them.)
Then, more recently, somebody exploited a weakness in the image gallery software and uploaded their own little files onto the box. And one of those files was a script that apparently was designed to let them hack away at CPanel, trying to get in.
Anyways, I've been doing my best to keep the third-party software up-to-date. And I've customized some of that code according to recommendations on their websites in a way that "blocks" bots and certain functions that these people might like to use.
But staying viligant sure does take a lot of time and energy.
Tonight, I'm going to uninstall their forums permanently. Nobody's been using them in the past several months anyways. But I sure don't want to uninstall their image gallery software.
I guess I'm wondering if there's some hosting provider out there who maybe specializes in helping provide churches with extra security?

I have a VPS with one provider and have recently opened an account with another provider, I want exactly the same install on there as what I had on the old provider. Is it possible to backup the whole thing on the old VPS and then restore it on the new one?
This would save a lot of time editing and configuring files, and make the switch easy.

I am trying to figure out a way to move a site from 1 host to another... The problem is that I don't just have a bunch of HTML files to move... I rented a VPS server for the last year, I believe it was CentOS 5 (OS). I setup several things on the server, MYSQL, FFMPEG, ETC...
I am now wanting to move to a dedicated server HOWEVER I DO NOT WANT TO START ALL OVER AGAIN. The site is rather busy and it is important to do the transition as fast as possible.
SO -- I have used Symantec Ghost before to "clone" a computer before. It basically takes an IMAGE of the entire HD and then you can paste/burn that image on a new HD and it makes a PERFECT copy of the original machine.
BUT - I have NO CLUE how to do this over the internet?

I'm thinking about moving an account with one main domain and a bunch of addons from one cpanel host to another, using a whole site backup .tar.gz file. SSH does not appear to be an option at this point.
I just extracted the tar.gz to a local pc to get a look at what's in it. It has these 12 folders: bandwidth, cp, cron, dnszones, logs, meta, mysql, resellerconfig, userdata, va, vad, vf. Below these folders are also 14 unfoldered files, ranging from "addons" to "version."
So, will this work?
1. Does this mean the domains and all the addons will be set up with their original user names, passwords, and email accounts with all the same passwords, if I move everything to the right location? Will all the email accounts I've set up in my email client software work just as they do now with the current host?
2. How can I know where all these uploaded folders and files have to be moved once they're there?
3. Can I just upload the extracted contents to one location, or do I have to upload the unextracted tar.gz to a server, extract there, then move the contents wherever they need to be moved (but I don't know where things need to be moved now)?

How do I setup a site to use two servers? One as a mysql server and the other as a web server.
At the moment I have the site on one server. When I get the second server what steps do I need to take to make this possible?
How do I secure the mysql server to only allow the web server to connect to it?
Do I need a control panel (i.e. cPanel) software on the mysql server?

Calling on all hosting and server experts here. (If you're not an expert, still feel free to take an educated stab at this. But please leave out total made up answers or foolish answers like "Have LittleJoeShmoe Hosting services do it all for $9.99/month".)
Scenario:
If you knew or were planning on developing a site that you knew would generate millions to tens of millions of page views a day, how would you go about supporting a site of such traffic? The site would not serve up videos, but the average page size would contain up to 75-100kB. It would incorporate databases (user logins, accounts, user submitted content, server side scripting, CMS, etc.)
Don't assume anything. Don't assume you have too little or too much money. Just, what would you plan out to accomodate such a scenario?
What hosting companies would you use? Would you do it in-house and build your own datacenter? Farm out the server management? How much would it cost to implement your plan? What platform would you recommend for a site to handle this much traffic?

I am currently moving from my current dedicated servers because they simply cannot handle the load. I have a site which frequently makes it onto radio, digg and other similar sites.
I need a dedicated server that can take a beating from Digg and offline Media. For most of the month the server load is really low, the site hardly uses up anything. However, when it hits those sites, it suffers.
I am OK with using Shell, just basic tars/logs/sqldumping/httpd.conf editing/rebooting etc.. anything beyond that like installing and configuring software I cant really do.
I guess I am looking at a dedicated option (linux based) with a host that'll setup software/modules modules for me when I ask, but doesn't really need to hold my hand all the time.
How are ThePlanet.com's servers? Do they manage the servers?

Its been a while since I have posted on here, anyway heres my problem.
I have a cPanel server in my office which handles the email for 2 domains.
I've also got a reseller account on a helm server.
What I want to do is: if I have a problem with the office server (outage) all emails will be routed to the helm server then delivered back to the office server once available. So any incoming email wont be bounced/lost.

I just got a VPS plan for the first time where I want to host several new websites. In the past I've used individual accounts to host a couple of other websites and haven't paid much attention to nameserver setup, just configured at my registrar whatever I was given from the hosting service.
So, I got a brand new domain to act as the host of the rest of the domains I'm setting up: www.example.com.
In the VPS I have setup this one as the default domain for nameservers: ns1.example.com
ns2.example.com
Question 1:
- Can I setup ns1.example.com and ns2.example.com as the nameserververs for www.example.com ? i.e. nameserver is used for the same domain in which it is named. Even if this is possible, is it a good idea or would it be better to host it somewhere else? When I try to define those as the nameservers in Godaddy I get the error message Nameserver not registered. What am I missing?
Other DNS questions
Question 2:
- If I host my nameservers in my VPS, I will need a separate IP for each one (ns1, ns2...and so on). Can I still use those IP's to actually host websites, or do I need additional IP's to host the actual sites? Any value in keeping each IP dedicated to a nameserver?
For example:
IP#1 = used for ns1
IP#2 = used for ns2
IP#1 = used for website 1
IP#2 = used for website 2
Question 3:
- Are DNS backup services valuable if I host my own nameservers? Any suggestions on good quality providers? Price not an issue.
Question 4:
- If I used DNS backup services for example.com will that apply to ns1.example.com and ns2.example.com which I used for my VPS? and therefore will be applicable to other domains I host? Does this make sense? Or would I need a separate backup for each domain I host? Can I use one backup for multiple domains?
Question 5:
- What are the drawbacks of hosting multiple sites under the same IP? I control all sites under these IPs
Question 6:
- Can somebody recommend a good resource to learn how IP, DNS, nameservers, etc work? Any book, paid website, video... anything ? While there's a ton of info on the web, all is scattered and none seems to be too detailed enough for somebody starting to learn about this.

to make a backup of my Cast-Control setup
and accounts, so I can install on a new server.
According to the Support website:
[url]
Its should be easy , using a SSH connection to backup,
but when I try the command:
tar -cvvf castcontrol.files.tar /home/MyDomain/public_html/myCast/
I get invalid directory!
I have notice that there´s no myCast folder inside my server,
on that directory there´s only the "castcontrol" folder.
I have tried with that, but same error!
Even not using any domain, just
/home/public_html/castcontrol/
