Yesterday (Feb 26, 2010), my web server was down with the message: "kernal panic... cannot access ex4 file on root...grub..."

I fixed it today with the following steps:

I used ssh to update drupal 6.14 to drupal 6.15 this morning. Here is what I did.

1. Remote login to the web server

1. download Ubuntu Server Edition 9.04

2. choose LAMP, OpenSSH, Print and Samba to install

3. Configure /etc/network/interfaces

sudo nano /etc/network/interfaces

For the Chinese and Thai, it is better to use unicode data. What I did:

Use phpMyAdmin to export data.
Use text editor to replace latin1 with utf8.

0. Install Ubuntu Server with a light DESKTOP to manage files.

1. download Ubuntu Server Edition 8.10

2. choose LAMP, OpenSSH and Samba to install

3. Install LXDE

1. Install Apache2

sudo apt-get install apache2

Install Apache Modules

sudo apt-get install libapache2-mod-auth-mysql
