Green Custom Web Hosting Solutions now available

Webmaster — Mon, 09 Nov 2009 19:49:44 PST

RrDNS.com and RrDNSHosting.com have both gone green as of today. Its been a while since we have been concerned about the harm our services can cause to the Ecosystem and moving a step forward we will be offering complete green webhosting solutions. We are proud to be able to play our own bit in the “Save earth, go green” campaign. Our new range of custom built green clustered solutions and shared hosting plans would be made public soon. A migration plan for existing clients who wish to get their clusters moved to green webservers without having to change their IP addresses is being worked upon as well. Clients will get a notification through email on what exact upgrade options they have available based on their existing hardware configurations. It gives us great pleasure to state that almost all upgrades which will made available to existing clients would not increase their monthly cluster costs. We have already had a few enquiries from existing clients about such upgrades and so a roll out on the first batch of such green upgrades would be done from 15th November 2009 onwards. Please feel free to contact us for further questions about green clusters or migrating your existing cluster to green services.

Clustered Mail Server Setup with @mail

Webmaster — Sun, 05 Jul 2009 06:06:41 PDT

We recently configured a clustered mail server setup and webmail for one of our clients using the @Mail Mail Server (http://www.atmail.com) . Using the multiserver configuration which @Mail supports, you can install more than one copy of @Mail on different machines to cluster the mail server and load the webmail interface from different machines. The software uses MySQL to store all the userdata and can be configured to use a central point for mail storage , it can support a multiserver configuration without any issues.

We won’t be going into much details on how exactly @Mail was installed as their own website provides very clear instructions about the installation in multiserver mode. You should make sure the NFS mount and all the required services For more details on these you can visit this knowlegde base article from the @Mail site itself. We will be looking into the Round Robin DNS setup which would need to be done for this setup.

You can run Pop3/IMAP , SMTP and Webmail services from different servers when you run @Mail in multiserver mode.You would need edit the DNS records for your domain to be able to utilize the cluster setup on your domain. We normally use ISC Bind as the nameserver on our setups and we used the same for this setup. We will consider the hypothetical domain used for the setup as yourdomain.com throughout this article.

Our cluster had three nodes namely: node1.yourdomain.com (123.123.123.126), node2.yourdomain.com (123.123.123.127) and node3.yourdomain.com (123.123.123.128) . We installed @Mail on all of them as per the official multiserver installation instuctions and it shared the same MySQL db and used the central NFS storage area as well. The setup requires the MX records for the domain to be pointed to all the 3 nodes. The MX priority for each of these mail servers should be the same so that the mails are distributed properly to these nodes.

The DNS entries for the nodes would be as below in the zone file:

node1         IN      A       123.123.123.126
node2         IN      A       123.123.123.127
node3         IN      A       123.123.123.128

The MX record for the domain needs to point to each of the nodes as below. The priority would remain the same. It is set to 0 in this case.

yourdomain.com.           IN      MX      0       node1
yourdomain.com.           IN      MX      0       node2
yourdomain.com.           IN      MX      0       node3

The above setup will set the incoming mails to be handled by any of the 3 nodes.

The remaining services would need to be load balanced to the different nodes in the same manner. This includes the Webmail and POP3/IMAP services. The setup in the DNS zone file would be as below. Using the round robin setup, if a node goes down in the cluster the request is automatically forwarded to the next node.

mail  IN      A       123.123.123.126
mail  IN      A       123.123.123.127
mail  IN      A       123.123.123.128

You would need the reload the DNS zone after making these changes or restart the service. You would need to verify the changes you made as below:

# dig yourdomain.com mx
 
;; QUESTION SECTION:
;yourdomain.com.                    IN      MX
 
;; ANSWER SECTION:
yourdomain.com.             86400   IN      MX      0 node3.yourdomain.com.
yourdomain.com.             86400   IN      MX      0 node1.yourdomain.com.
yourdomain.com.             86400   IN      MX      0 node2.yourdomain.com.

You can find below that mail.yourdomain.com resolves to 3 Ips as below.

# nslookup mail.yourdomain.com
Server:         127.0.0.1
Address:        127.0.0.1#53
 
Name:   mail.yourdomain.com
Address: 123.123.123.126
Name:   mail.yourdomain.com
Address: 123.123.123.127
Name:   mail.yourdomain.com
Address: 123.123.123.128

Using this method you can setup a load balanced mail cluster using @Mail. If you have additions to make, they are always welcome

Cluster Setup for an Autosurf Website

Webmaster — Thu, 21 Aug 2008 02:24:42 PDT

Over the years, mutual traffic exchange programs have been gaining popularity as a medium to promote websites. Most of these programs/websites use autosurf technogies to generate hits for their advitiser or member’s websites. Various HYIP and Paid traffic exchange programs using autosurf scripts as their base exist on the internet. The cluster setup we did was for a site which was purely designed for mutual traffic exchange with no paid services. The member sites needed to add banners and ads from the parent website in lue of the traffic exchanged via the site.

This site gained a huge membership base in just a few months and had traffic which could not be manged by a single dedicated server. The site involved an autosurf bar which checked for the banner/ads existence on the member site and rotated it amongst the members every few minutes. The amount of hits the member’s website would receive is dependent on the amount of sites he would surf via his own autosurf area.The cluster we setup had the structure as below:

WebServers: The webservers were the most busy nodes of this cluster. Their site was all about generating http traffic and their members were on the site almost all the time. The autosurf structure made sure that no member was idle and so the http hits were continous and enormous in number. We had to use 3 webservers to be able to manage the amount of traffic this site was getting. Each of the webserver nodes was setup with Lighttpd + PHP as Fastcgi for faster site performance and dynamic page generation.

The configuration for the webservers we used was:

Intel Pentium Dual Xeon 2.8 Processor
2GB DDR2 RAM / 160GB SATA HDD Drive
CentOS 4.6
1000Mbps Uplink
Private LAN Connections to other Nodes on the Cluster

Master Mysql Server: All the three webservers connected internally via private switch to the master Mysql server. All the site’s membership data and hits stats were being stored in the database and database traffic was huge as well as each hit was being logged into mysql. The client needed managed mysql backups and redundancy and so mysql replication was used for the cluster. Due to the amount of mysql activity on the master mysql server, generation of backups from this node was almost impossible. We used replication to sync the db data on the slave server and used the slave server for generating mysql backups. The configuration we used for the Mysql Server is as below:

Intel Pentium Quad Core Q6600 Processor
8GB DDR2 RAM/ 1×300GB SCSI 10k RPM Drive
CentOS 4.6
100Mbps Uplink
Private LAN Connections to other Nodes on the Cluster

The slave Mysql server also acts as the mail server for the setup. The mailing activity for the site is moderate and so only one mail server is being used.

Intel Pentium Quad Core Q6600 Processor
4GB DDR2 RAM/ 1×300GB SCSI 10k RPM Drive
CentOS 4.6
100Mbps Uplink
Private LAN Connections to other Nodes on the Cluster

This setup distributes the traffic for the site to the three nodes using round robin DNS which is managed by the TTL. Comments are welcome as always.
