SSD VPS? Linode SSD Beta.

Linode is the VPS service provider. I start to use it from May.

The service it provides is so good. Let me summarize it.
Linode 1024MB RAM

  • 8 CPU
  • 48 GB Storage
  • 2 TB Transfer
  • $20 / month

I am also using Digital Ocean SSD VPS. It has SSD storage.

Now Linode announce it has a SSD beta for existing users.

There are certain limitation and notes for this BETA.

  • It’s only in Newark right now
  • We’ll move one of your existing Linodes to one of these special hosts
  • There are limited slots available
  • This is experimental
  • You might lose all of your data
  • Participate at your own risk
  • You really should have backups
  • Expect the unexpected
  • This may cut you
  • Chicks dig scars

I applied it two days ago, at night. The reply is so quick, and I completed the migration in one hour. My existing VPS in Fremont, CA, is moved to Newark, NJ.
New IP address.

The SSD is not storage. It is a part of storage layer. It means the SSD Beta is a combination of ‘good stuff’ SSDs (in redundant pairs) and proven hard drive storage system.Like a hybird storage.

Stop mt-comments.cgi to save memory

I can not publish new post in this blog. So many 500 error when I click publish, some times when I click signin.
The 500 internal error is because my blog, MovableType ate a lot of memory when it running. The Dreamhost is monitoring the resource user is using. It will kill the thread when it over the limit. Actually they don’t tell you the limit of it. They just tell you, it is time to upgrade to their VPS.
I connected the server through ssh. Run top command to see which one is more popular.
Yes, I found it. More than one mt-comments.cgi stay on the list.
To temporary solve the problem, I rename the mt-comments.cgi to other name. Then sign in the backend of MoableType.
Click Settings, Feedback, Uncheck the check box after Accept Comments.
Then, republish the whole site.

Three steps to make your own VPS

It is not that easy for a newbie to make a workable VPS by himself.
I have three year experience on VPS. I can make it as simple as possible to show you how to do it in three steps.
You need a VPS at least. I recommend BurstNet. The price is good. The service is OK per price.
After you order your own VPS and paid the invoice, you probably get the email in 8 hours for your account information.
You have panel and ssh account.
Went to panel and rebuild your VPS by choosing Centos 5 minimum OS template.
Now it is my three steps
1) Step 1
SSH your VPS by root user. Enter following command to install httpd

yum install httpd-devel

2) Step 2
Install MySQL server, and start MySQL server.

yum install mysql mysql-server mysql-devel
/etc/init.d/mysqld start

3) Step 3
