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.
I have 2 servers. How do I setup the DSN for these 2 servers with my domain? For example, I have domain "mydomain.com" and server1 and server2. I want
ns1.mydomain.com, ns2.mydomain.com --> server1
ns3.mydomain.com, ns4.mydomain.com --> server2
Both server installed cPanel/WHM.
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.
Currently i'm running a server with 12 customers on it. They all have their own domainnames and subscriptions. One of them wants to secure his site with SSL and also his mail traffic. Currently he is using the mail.hisdomain.com server for receiving/sending e-mail. I want to install a certificate so that domain is secured. How can i accomplish this?
When i look on the server there is only 1 PEM file for the whole server. If i'm going to install his KEY and CRT in that file than all my clients will use that certifcate right? Can i make it so that only his domain uses thoses certifcates? Plesk is configured to use Postfix with Courier.
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.
if there is any tutorial to setup 2 email servers serving just 1 domain?
Currently, i have 1 dedicate email server running centos with DirectAdmin, it works just fine.
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 have signup with everydns. I have read faq for secondary DNS but not understand.
View 1 Replies View RelatedHi there, i have few question for the best suited DNS Setup for our compagny.
We have tree server located in montreal.
Two are running web services, one of them is only for dns ( home server ).
Two main server have Whm/Cpanel.
One run Cpanel Dns only.
Main server have 7 ips each
Dns server, only have 1
Let say we use domain xxx.com
Right now we have ns1/ns2/ns3/ns4 point to server1
ns5/ns6/ns7 point to server2
We have no Nameserver that point to our dns only server for now.
I'd like to advoid runing DNS Service on all of them, maybe having two slave one master would be fine. Question: What would be the best suited dns setup with my current config for best responding time and fast replication?
I have registered a domain using godaddy. I have hosted my site on a server of my shared hosting provider(lets call them X).Currently I have pointed mydomain.com to the server and it is up and running.Sometimes, I have experienced downtimes.
In order to solve this problem, I have hosted a clone of my site on another server from another hosting company(lets call them Y).
1. I want mydomain.com to point to Y when X is down
2. again point it to X when it is up.
My main aim is to have my site live with less downtime. The probability having both servers down is very less.
I dont know if it is technically feasible, just a thought out of dirty mind. I tried to google but was not able to find an answer specific to my problem.
Can anybody tell me how to achieve this through godaddy domain.
Added note, My site is not a commercial site and I cant afford large dedicated servers with clustering and failovers.
I have 1 server so I setup dns as ns1.mydomain.com, ns2.mydomain.com ip address pointed to server1. So, now I just bought another server. Can I setup ns2.mydomain.com pointed to 2nd server. Also how to setup more servers ie. 10, 20 server because I can only set up to 6 dns in one domain name.

I have a dedicated server with cpanel. So i setup nameservers there. like ns1.ABC.com and ns2.ABC.com
So now i wanna host ABC.com in that server. My registrar is Godaddy.
So how to setup at godaddy? can anyone guide me.
Is it like make hosts like ns1 and ns2 and put the IPs from the server in the fileds?
Then i have to put the nameservers fileds also ns1.abc.com and ns2.abc.com too. Or just making ns1 and ns2 hosts enough?
I currently have two VPS servers, each with 2 DNS names running on them as follows:
dns1.mydomain.com (on Server A)
dns2.mydomain.com (on Server A)
dns3.mydomain.com (on Server B)
dns4.mydomain.com (on Server B)
I have websites running on each server and I would like to have something set-up so that when one server goes down, the other server displays a nice page saying the website is unavailable currently and will be back shortly - you know, something nicer then the normal "Server Not Found" default messages.
What is the best way to do this?
If I have CLIENTDOMAIN.COM and put them on Server A and they use all 4 DNS server names, will the top two DNS names always be used by people finding the website, and the bottom two choices only be used if the top two can't be found?
I believe I have to create an account on Server B for them as well, just only placing the temporary page within the account, rather then a whole copy of their website. Correct?
We are currently looking into getting a new setup to serve our online store, and I would be thankful for feedback as to which servers to choose.
Today almost the entire store is on a single three year old dual proc/dual core server (4 gb ram, RAID5) that is beginning to get overloaded. (There is also a simpler secondary server that serves some static content and does some cron jobs.)
The system is a in-house developed LAMP (where the P is mod_perl/Mason). The database is rather large, two tables with 2-6 million rows are hit multiple times on most public pages - these grow with ~10% per year. Several other often-used tables are in the few-hundred thousand to a million rows, also continuously growing.
We anticipate rapid sales/visit growth over the next couple of years (a good day today is 6000-8000 visits), so I'm thinking of separating the database and web server. The most likely hosting candidate right now is Softlayer's WDC data center (we are located in Europe).
With that background, does this sound like an adequate setup:
Database server
Dual Xeon 5430 - 2.66GHz
8GB ram
RAIDed 3x73GB (or possibly 147GB) (15k rpm). I'm thinking RAID1? The big tables are not written to too much during the day, so read performance is more important than writing.
Web server
This (these) would be serving the Apache/mod_perl part of the system. Some static content (images and some PDFs) unless we put them on a separate server (all static content are placed in a single folder so it would be easy to do a mod_rewrite to an image server).
Dual Xeon 5050 or 7320
4GB ram
2x73GB (SCSI 10k rpm) RAID1
I don't think we need to load balance between two web servers from the beginning but that is something we will keep in mind (and hopefully have to do at some point). Are the two configurations sane (or is one overkill compared to the other)? Generally, how many web servers can a single database server serve? Email is handled separately (Google Apps). I estimate our budget to not more than $1000-1500 a month (if we go with Softlayer we will most likely use some other services such as firewalls, SAN and so on).
We currently use Suse, I have previously used RedHat on personal servers at ThePlanet. Is RedHat 4 32-bit a sensible choice? I have some experience with CPanel so we would most likely use that.
We're building a bunch of new servers (as I mentioned in another thread). What do you guys think is the best drive layout? Traditionally we just have the entire 4-6 drives in a RAID 5, but now I'm wondering if it makes sense to have a separate OS drive, and then the rest in a raid 5?
On a side note, we need a giant ~2TB-3TB partition on these boxes, that's why we go with the multi-drive raid setup. Thoughts? I know it was customary to have a separate OS drive back in the day (I remember having WD raptor's for that), but now when the WD Black-edition (which we'll be using for the raid setup) are as fast as the raptor's, is it even worth it?
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?
I have a server at volumedrive it has cpanel and whm installed etc I am trying to setup the name servers but everytime it fails is there something that I might be missing?
View 4 Replies View Relatedsome setup recommendations as I feel I have outgrown my current server.
I have two websites:
#1 is a busy vBulletin based forum with 42,000 members.
#2 is a website with Wordpress and Vbulletin installed (though the forum is nowhere near as busy as the first site) and gets roughly 2000 uniques a day.
When site #2 gets a good surge of visitors from offline media or a large site, site #1 will die first with the "mysql error: too many connections" error and site #2 will take a very very long time to load.
For every other day, the load is quite low, nearly always under 1.50.

A files server and a sql server?
A server for site #1 and another for site #2?
A single, more powerful server?
Or something else you recommend?
Also, for the setup you do recommend, can you recommend a hosting company that is reliable and can do it for a good price?
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.

One of our customers need to use a domain.de (.de ext), he registered the domain using godaddy, and godaddy have a few very special requirements for .de domains:
• The first 3 bits of the IP address (C-class) is different for each name server.
• A glue record is necessary for the domain on the name servers.
• The SOA (Start of Authority) must be within the following guidelines:
refresh : 10000 - 86400
retry: 1800 -28800
expire: 604800 - 3600000
ttl: 180 - 345600
This is all done, 2 different C class IPs for each name servers, glue record, and SOA has been configured between specified values. Because of the 2 C class, we created DNS at server1, and pointed all www traffic to server2 (where the domain.de will be hosted)
This is the DNS zone at server1 (an Ensim server):
$ORIGIN .
$TTL 3600 ; 1 hour
sitename.de IN SOA nameserver1.server.com. support@hostingcompany.com. (
2008010804 ; serial
10000 ; refresh (1 hour)
1800 ; retry (10 minutes)
604800 ; expire (2 weeks)
345600 ; minimum (1 hour)
)
NS nameserver1.server.com.
NS nameserver2.server2.com.
$TTL 86400 ; 1 day
A XX.XX.XX.XX
$ORIGIN sitename.de.
ftp A XX.XX.XX.XX
www A XX.XX.XX.XX
This is the DNS zone at server2 (an cPanel server):
; Modified by Web Host Manager
; Zone File for sitename.de
$TTL 3600
@ 86400 IN SOA nameserver2.server2.com. support@hostingcompany.com. (
2008010804
10000
1800
604800
345600
)
sitename.de. 86400 IN NS nameserver2.server2.com.
sitename.de. 86400 IN NS nameserver3.server2.com.
sitename.de. 14400 IN A XX.XX.XX.XX

sitename.de. 14400 IN MX 0 sitename.de.
mail 14400 IN CNAME sitename.de.
www 14400 IN A sitename.de.
ftp 14400 IN A XX.XX.XX.XX
While checking the domain at [url], an error appears:

Secondary nameserver2.server2.com. IP_ADDRESS_HERE
Test results
---- fatal ----

I have verified every single thing at sitename.de.db on both servers at /var/named/, disabled DNS Recursion protection, stopped firewall, and the error continues.
And the error as you can see only happens with SOA at second server.

I've been running a Plesk server with around 100 domains for years and years now. I've always used a backup service provided by the server vendor, but with a new server, I wanted to consider some of the backup options built into Plesk.
1. It looks like Plesk/Acronis is dead or only for Windows. Is that right?
2. If I add a backup drive to the server, can I setup Plesk Backup Manager to store the backups there (instead of on the main RAID array)?
3. Are there any other 3rd party extensions that I should consider?
I have a VPS account with WHM/Cpanel console access. I have three domains that I am trying to setup. Within WHM I have setup three different accounts, one for each domain. I am able to login to the cPanel for all three accounts. This also created a new web directory for each domain in /home/domain_name/public_html/. I have placed my default index.php in all three public_html with the same permissions. But only 1 domain is working the other two are not. What am I missing? I have confirmed that all three have the correct DNS servers with godaddy and I can do an nslookup on all three. My provider told me to share the IP so that is what I am configured as..
