Wow, I’ve been busy since OOW2011. This is the first post since I left for San Francisco. My Android phone got blown out by a forced upgrade and would only charge when actively connected across the USB to the computer. At the conference, my laptop was sidelined as a charger.
Anyway, I’m back working on virtual environments again. I found a couple slight variation installing VMWare Tools on Oracle Unbreakable Linux. Here are the post installation steps that I encountered, and the IP addresses are based on how VMWare configured DHCP, which is qualified in this older post.
- Navigate to the VMWare Menu, choose Virtual Machine and in the drop down menu Install VMWare Tools. This will mount a virtual CD in the Oracle Unbreakable Linux virtual machine and it launches the following dialog box:
- Open a terminal session by right clicking anywhere in the desktop, and then choose Open in Terminal from the context menu. You can then run the VMWare Toolkit by following these instructions:
cd /media/VMware\ Tools cp VMwareTools-8.4.7-416484.tar.gz /tmp cd /tmp gunzip VMwareTools-8.4.7-416484.tar.gz tar -xvf VMwareTools-8.4.7-416484.tar cd vmware-tools-distrib sudo ./vmware-install.pl
The last step requires that you reply to a set of prompts. If you’d like to accept the default at one time, you can use the following command:
sudo ./vmware-install.pl --default
You should most likely encounter an error like the following, which it appears you can ignore. If I find anything to the contrary, the post will be updated with findings.
(EE) Failed to load module "vmwgfx" (module does not exist, 0) (EE) vmware: Please ignore the above warnings about not being able to load module/driver vmwgfx (EE) open /dev/fb0: No such device
- In the terminal session you should configure three files to make sure your networking works. I found that the dialogs failed to set one key element, so it’s simply easier to do this manually. Rather than using
sudo, you should open a
rootshell by doing:
su - root
Enter your user’s password:
You should use
vi to edit and save the
resolv.conf file with appropriate domain, search, and nameserver values. The values below work for VMWare when the gateway IP address is
# Generated by NetworkManager domain localdomain search localdomain nameserver 172.16.123.2
vi, edit the
/etc/sysconfig/network file to include an appropriate gateway IP address, like so:
NETWORKING=yes HOSTNAME=localhost.localdomain GATEWAY=172.16.123.2
The last file to fix is
/etc/sysconfig/network-scripts/ifcfg-eth0 file. This is the file that isn’t completely configured by the GUI component (it fails set the
ONBOOT value to
DEVICE=eth0 HWADDR=00:0c:29:31:ef:46 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp TYPE=Ethernet DNS1=172.16.123.2 USERCTL=no PEERDNS=yes IPV6INIT=no
You reset networking with the following command:
As always, I hope this helps a few folks.
Somebody asked why adding a user to the
wheel group in Oracle Enterprise Linux didn’t enable them as a sudoer, as qualified in my earlier Fedora post. The reason is that you also need to modify the
/etc/sudoers file to specify users allowed that privilege (and the file differs from it’s Fedora cousin). If you have the
root user privileges, you can do the following:
- Change to the
rootuser account with
su, and provide the password when prompted. The syntax is:
su - root
- You can find the line you need to change with this command:
cat /etc/sudoers | grep %wheel
#comment. If you don’t want authorized sudoers to provide a password, modify the second line by removing the
#comment. Open the
geditif you’d like a GUI editor.
# %wheel ALL=(ALL) ALL # %wheel ALL=(ALL) NOPASSWD: ALL
Hope this helps, I’m off to Oracle Open World 2011 tomorrow.
Quick update for Fedora 20, you
root and add your user to the
sudoers list with the following syntax:
usermod someusername -a -G wheel
By the way, don’t forget to log off and then back on to the account.
