Setting up Oracle on Ubuntu Running on Parallels

I recently created a Parallels image for some classmates running Ubuntu with Oracle 10gR2. I included instructions on how I created the image and I thought it would be helpful to anyone else out there to see how I did it (not necessarily how it should be done). To make this post more searchable from Internet search engines, I've included all the steps here rather than posting a link to a pdf. Enjoy!

SUMMARY:
Ubuntu Server
User: duser, pw: duser
User: oracle, pw: oracle
Hostname: vm-ubu-oracle
Static IP: 10.211.55.10
Webmin:
User: root, pw: duser
Link: http://vm-ubu-oracle:10000
Oracle:
SYS pw: oracle
Admin: http://vm-ubu-oracle:1158/em
TNS Entry:
ORCL10 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = vm-ubu-oracle)(PORT = 1521))
)
(CONNECT_DATA =
(SID = ORCL10)
)
)


Setup Parallels Networking
Note: All networking is using the Parallels default for shared networking. Some of this has to be tweaked a little to allow for static IPs and to ensure a consistent network between your Ubuntu Server and your Mac.
Go into your OS X System Preferences, Network
Click on Parallels NAT, Configure
Click on TCP/IP
Change Configure IPv4 to "Manually"
Set the IP Address to 10.211.55.6
The last number in the IP address can be anything between 2 and 9. Whatever you choose will be the IP that the Ubuntu server will see your Mac as. I will be using 6 throughout this documentation. (Also set: Subnet Mask: 255.255.255.0, Router: 10.211.55.1)
Click Apply Now and close System Preferences
Open Parallels, Preferences
Under the Network Tab, ensure that "Enable DHCP scope for shared networking" is enabled.
The 3 IPs should be as follows:
Start: 10.211.55.10
End: 10.211.55.254
Mask: 255.255.255.0

Software to Install (leave blank)
NOTE (courtesy of http://paul.annesley.cc/articles/2007/05/01/ubuntu-704-feisty-server-parallels-cdromkernel-workaround):
On the “Installation Complete” dialogue, choose “Go Back”, and then select “Execute a shell” from the menu. Run the following commands (ignore any errors and accept defaults if prompted):

umount /dev/scd0
chroot /target /bin/bash
mount /dev/scd0 /media/cdrom
aptitude install linux-generic
aptitude remove linux-server linux-image-server linux-image-2.6.20-15-server
exit
shutdown -h now
Setup access and aptitude
login as duser
sudo visudo
add the following line if you wish to not be bugged when running sudo
WARNING! This isn't considered safe practice. I just do it because of the volume of sudo commands that will be entered during the setup. If you wish, you can remove these edits once the setup is completed to be safe:
duser ALL=(ALL) NOPASSWD: ALL
change the members line to read:
%admin ALL=(ALL) NOPASSWD: ALL
edit the apt sources list to pull from the online repository
sudo vi /etc/apt/sources.list
comment (#) out the line that starts: deb cdrom:[Ubuntu-Server 7.04...
update the local repository by running:
sudo aptitude update
install ssh and samba (accept defaults on dependencies)
sudo aptitude install ssh samba

Setup some Environment Variables (this is a personal preference and can be omitted)
Add the following lines to the ~/.bashrc file
if [ -f ~/.bash_env ]; then
. ~/.bash_env
fi
create a file in ~ called .bash_env
add the following lines to .bash_env
PS1=“\h: \W$ “
TERM=linux

Setup Webmin
Note: you should be able to login to the server using Terminal or iTerm. Check the ip address using ifconfig. The ip that my server got was 10.211.55.7. Yours will be similar. I would suggest using a terminal from here on out because of ease of copy and pasting commands and screen scrolling.
Download Webmin
wget http://downloads.sourceforge.net/webadmin/webmin_1.360_all.deb
Install prerequisites:
sudo aptitude install libauthen-pam-perl libio-pty-perl libmd5-perl openssl
Install webmin
sudo dpkg -i webmin_1.360_all.deb
Update your admin password
sudo /usr/share/webmin/changepass.pl /etc/webmin root
I used "duser" as the password
Navigate your web browser to https://:10000
You should be able to login as root with the password entered earlier

Setup Static IP
Login to webmin
Navigate to Networking, Network Configuration
Under "Interfaces Activated at Boot Time" click on eth0
Change the IP to static and apply the following:
IP: 10.211.55.10
You can use any range from 5 to 254. I will be using 10 from here on out
Broadcast: 10.211.55.255
Netmask: 255.255.255.0
Click Save.
Click the checkbox next to eth0 that you just modified and then click the apply button.
This will send your browser into a constant state of refresh. Just click stop and enter the new ip address in the address
Setup routes under Network Configuration
Default Router: Gateway: 10.211.55.1
Active Route 1:
Destination: 10.211.55.0
Gateway: None
Netmask: 255.255.255.0
Interface: eth0
Active Route 2:
Destination: Default Route
Gateway: 10.211.55.1
Netmask: (nothing)
Interface: eth0
Save changes and apply.
Setup a hostname on your Mac by adding the following to the bottom of the /etc/hosts file on your machine:
10.211.55.10 vm-ubu-oracle

Setup Samba
Samba can be setup manually from the command line, but webmin makes it simple
Navigate in webmin to Servers, Samba Windows File Sharing
Click on Windows Networking
Change Workgroup from MSHOME to WORKGROUP
this is for better integration with Windows if you ever need it
Set Server name to vm-ubu-oracle
Save
Click Edit Config
Scroll to the Share Definitions section and change the homes section to look like this (removing the semicolons):
[homes]
comment = Home Directories
browseable = yes
writeable = yes
Add your user to Samba by executing the following command:
sudo smbpasswd -a duser
(you should now be able to mount the home directory on your Mac from Finder using: smb://)
