How to setup a Ubuntu server?

Requirement:

Software: Ubuntu ISO image, unetbootin

Hardware: A 4 gb usb stick

1. Download Ubuntu ISO image from thisurl:

Http://mirrors.163.com/ubuntu-releases/10.04/

Select your favorite releaseversion, and download it.

2. Use unetbootin to create a bootable USB stick.

Http://unetbootin.sourceforge.net

3. Install Ubuntu with this USB stick.

 

Now, we have a new installed Ubuntu environment. There are several steps need to bedone.

1. setup network configure

Ubuntu is configured in192.168.9.x, and uses a gateway and a web proxy to connect to the Internet.

We can configure these settings byubuntu GUI tools.

For example:

Gateway: 192.168.9.180

Proxy: proxy. Local (authenticate information shocould be supplied)

After these steps, we must setupnetwork for apt-Get (Notice: global network settings doesn' t influent apt-getnetwork settings, they are independent .)

Login as root, and modify/etc/APT/apt. conf, add authenticate information after proxy server. Forexample:

Acquire: http: proxy "http: // username: PASSWORD@proxy.local: 80 /";

Acquire: ftp: proxy "ftp: // username: PASSWORD@proxy.local: 80 /";

Acquire: https: proxy "https: // username: PASSWORD@proxy.local: 80 /";

2. Create user account & directory

Login as root, and run thesecommands, for example, we add a user whose name is Cisco.

Create user:

Useradd Cisco # Add User

Passwd Cisco # createpassword for Cisco

Gpasswd-a Cisco admin # Add Cisco to Admin group

Mkdir-P/home/Cisco

Chown Cisco/home/Cisco

Chgrp Cisco/home/Cisco

Create directory:

The TFTP directory is created under /.

Mkdir/tftpboot

Mkdir/tftpboot/Cisco

Chowncisco/tftpboot/Cisco

Chgrpcisco/tftpboot/Cisco

The project directory is under ~ :

Mkdir/home/Cisco/Project

3. Install & configure samba

Sudo apt-Get install samba

Modify/etc/samba/smb. conf, addbelow lines:

[Cisco]

Comment = Cisco's project directory

Path =/home/Cisco/Project

Public = Yes

Writable = Yes

Valid users = Cisco

First, create account for thisuser:

Smbpasswd-a Cisco

Then create password for Samba User:

Smbpasswdcisco

And start Samba:

Servicesmbd start

4. Install TFTP Server

A. APT-Get install xinetd tftpd TFTP

B. Create/etc/xinetd. d/TFTP and putthis entry:

Service tftp

{

Protocol = UDP

Port = 69

Socket_type = dgram

Wait = Yes

User = nobody

Server =/usr/sbin/in. tftpd

Server_args =/tftpboot

Disable = No

}

C. sudo/etc/init. d/xinetd start

5. Change runlevel to text mode

Run in text mode will use verylittle memory. We can modify/etc/default/grub and a simple "text" after grub_cmdline_linux_default, just like that:

Grub_cmdline_linux_default = "quiet splash text"

And do not forget run "sudoupdate-grub" to update.
