Since I started using ssh remotely to manage servers like 12 or so years ago I have been in love with its power and what you can do with a few command lines. In the last 7 or 8 years many web based control panels have appeared making life easier for the end user. One would expect that ssh would go obselete now that you can do things with a few mouse clicks. Not really.

Last night I was trying to activate an IP by setting “Active in IWorx-CP” to yes under IP Management of Nodeworx but it gave me blank screen. There was no error. I could not see anything in logs. So I fired a ticket with interworx support and here was their response:

Try running this script and see if adds the IPs as expected:

~iworx/cron/ip.pex—sync

Yes, finally something to do via shell. So I did and it resolved the issue. Moral of the story, the real thing is still linux shell

Offering businesses virtual private servers as a comparable option to dedicated hosting looks to drive down cost and reduce power consumption of hosting datacenters

HOUSTON, TX. July 16, 2008 – WowVPS! web hosting, providers of virtual private server (VPS) hosting services and a subsidiary of Landis Holdings Inc., today announced a new promotion of 25% off all “Xen” hosting plans starting from only $10.45 per month. Besides reducing ongoing operating costs for companies during tough economic times, shifting usage from dedicated servers to virtual private servers can reduce overall required power consumption.

“Socially responsible web hosting involves making choices that meet a company’s hosting needs while minimizing the impact on the environment,” says Greg Landis, president of WowVPS!. “While the focus has been mainly on new technologies to reduce power consumption, sometimes the simplest answer is selecting the right hosting plan. Our VPS hosting plans offers businesses an attractive option of improved flexibility of dedicated hosting at prices much lower than full dedicated packages.”

WowVPS! utilizes the latest version of VSControl virtualization software from Devpond, another subsidiary of Landis Holdings. VSControl software was developed in-house and eliminates the software cost which often leads to increased VPS hosting prices. WowVPS! offers plans with higher specs than any other VPS provider while maintaining 100% uptime.

WowVPS! starts with the “Xen Awakening” entry level plan, regularly priced at $13.95 per month but on special for only $10.45 per month, and includes:

• 12 GB disk space
• 200 GB bandwidth
• 192 MB or RAM
• Unlimited domains
• Free 3 VPS IP addresses

All WowVPS! “Xen” hosting plans include:

• Full VPS root access
• RAID 10 disk storage
• Guaranteed RAM
• Premium bandwidth
• Multi-core, multi-processor CPUs
• VSControl software
• No oversold resources
• Choice of Linux OS
• No contract obligation; cancel any time
• Online server and service restarts

The new WowVPS! web site includes a community forum, a blog, user-friendly control panel and the NixCore client management software.

A question we often get asked is, “What is the difference between your VPS plans and your SDX (Semi-Dedicated) plans?”

Semi-Dedicated
Our SDX plan is basically one shared hosting account on a powerful server. What’s different compared to our standard shared hosting plan is that there far fewer accounts on our SDX servers. So you have more resources available to you. For example, if you have a fairly busy forum not suitable for regular shared hosting, you would want to purchase our Semi-Dedicated hosting plan.

SDX is not intended to be used to resell hosting since it is still a basic shared account. It’s intended for those who still want a shared hosting environment that packs a bit more punch. Our SDX plans are also good for a video share website.

VPS
A VPS (Virtual Private Server) is sort of like having a dedicated server in terms of customization abilities but without the extra cost (because it’s still a shared hosting environment). Our VPS plan offers full root or administrator access and you have full control over the settings and software on the server. Think of a VPS plan as having a partition on a large server.

You would have a choice of which OS (operating system) you wish to have installed. The choices are:

• CentOS (most popular)
• Debian
• Fedora Core
• Suse
• Windows<

You can also choose which version of MySQL, PHP, mail, etc. you want installed. (You cannot do this with Semi-Dedicated.) In addition, you get the choice on which control panel you’d like to use to administer your VPS. The choices are:

• cPanel
• Direct Admin
• Interworx
• Plesk

SDX plans come with cPanel only.

A VPS account can be used to resell hosting if you desire. In a nutshell, VPS plans allow you to completely customize the Virtual Private Server to suit your hosting needs.

This is also discussed in the JaguarPC Forums in this thread: VPS vs Semi dedicated

Both are powerful hosting solutions and JaguarPC provides both options at very reasonable prices. Check out these current specials:

MySQL provides cluserting but not fail over for end user. So here at JaguarPC Web Hosting labs we tested MySQL fail over cluserting. To setup MySQL clustering a minimum of 3 computers are required. However recommended number is 4 or more. And to setup a failover mysql cluster, we add one more machine making it 5. There are 3 parts in a MySQL Cluster:

Data: 2 or more nodes act as data. In MySQL 5.0, the data sits in memory, while in 5.1 data can go on disk as well (5.1 is release candidate). For our testing we use 2 data nodes. When one of the node dies, the other will serve the data.

Management: One machine is used for cluster management. Once the cluster is started and this machine goes down, the cluster can continue to work. So this is not critical for our fail over setup.

SQL:: 2 test machines were setup as SQL nodes in failover with a single “floating IP”. When one died, the “floating IP” moved to the second machine using arp spoofing. MySQL client would connect to SQL node using that floating IP, so for the client MySQL Server remains up and running when one of the SQL nodes die. This part of the setup is JaguarPC’s own making and is available through Dedicated Server Hosting offer.

The rough diagram for this whole setup is as follows:

MySQL client -> [ 2 SQL nodes fail-over ] -> [ 2 data nodes ]

RAM Requirement for Data Node: Since MySQL 5.0 uses RAM to hold the data in data nodes, you can use the following formula for obtaining a rough estimate of how much RAM is needed for each data node in the cluster:

(SizeofDatabase × NumberOfReplicas × 1.1 ) / NumberOfDataNodes

Say our database size is 10 GB, and we make 2 replicas and host it on 4 nodes, then we need about 6GB RAM in each node. If we store our 10GB with 2 replicas in 6 nodes, then we need 4GB RAM in each node. You get the idea.

More will be posted later about this topic.

Step 1) Edit the /etc/resolv.conf file
Check if the IP addresses for nameservers are as follows.
nameserver 127.0.0.1
nameserver 192.168.1.1
nameserver 192.168.1.2

If not please change it. Webalizer checks resolve.conf file before generating the webstats.

Step 2) Go to the path /usr/local/cpanel/src/3rdparty/gpl/webalizer-2.01-10
Then run the following command
./configure—enable-dns—with-dblib=/lib

Step 3) Then run /scripts/runweblogs to see if the changes are updated.

You need to make one change to your httpd.conf file in the /etc/httpd/conf directory. (It is advised that you make a backup of the file BEFORE making any changes.)

Edit the file, look for HostnameLookups and change the value to On. Save the file and restart the web server i.e.
/etc/rc.d/init.d/httpd restart
