Laptop sekarang makin canggih ya… Jaman dulu ngebayangin pake RAM 512KB aja udah hebat… eh sekarang Lenovo gue dijejalin RAM 8GB… konsekuensi nya emang musti fresh install Ubuntu 64Bit… Kernel PAE kayaknya kurang greng… tapi sekarang arsitektur AMD64 ini udah menyenangkan koq… Flash bisa jalan tanpa effort yang berlebihan…

Emang enak ngejalanin VirtualBox… bisa foya2 kasih RAM ke guest sampe 1GB…

Tapi… Omong2… lebay nggak sih… pake RAM 8GB di laptop?

None of the pre-built vmmon modules for VMware Server is suitable for your
running kernel. Do you want this program to try to build the vmmon module for
your system (you need to have a C compiler installed on your system)? [yes]

Using compiler “/usr/bin/gcc”. Use environment variable CC to override.

Your kernel was built with “gcc” version “4.1.3″, while you are trying to use
“/usr/bin/gcc” version “4.3.2″. This configuration is not recommended and
VMware Server may crash if you’ll continue. Please try to use exactly same
compiler as one used for building your kernel. Do you want to go with compiler
“/usr/bin/gcc” version “4.3.2″ anyway? [no]

I don’t think it is wise to force version “4.3.2″, the hint said to set the CC environment to point to gcc version “4.1.3″… so… since I already have gcc-4.1 installed…

$ dpkg -l | grep gcc-4.1
ii gcc-4.1 4.1.2-25 The GNU C compiler
ii gcc-4.1-base 4.1.2-25 The GNU Compiler Collection (base package)

I simply ran…

export CC=/usr/bin/gcc-4.1

and re-ran the vmware-install.pl file…

Using compiler “/usr/bin/gcc-4.1″. Use environment variable CC to override.

What is the location of the directory of C header files that match your running
kernel? [/lib/modules/2.6.26-1-amd64/build/include]

It didn’t seem to warn about the difference in the minor version…

Ubuntu JeOS has been tuned to take advantage of key performance technologies in the latest virtualization products from VMware. This combination of reduced size and optimized performance ensures that Ubuntu JeOS Edition delivers a highly efficient use of server resources in large virtual deployments.

dapat saya simpulkan bahwa sistem operasi ini telah dioptimasi untuk bekerja dalam kondisi virtual. Dimana sudah diikut sertakannya kernel virtual dan dihilangkannya komponen-komponen yang tidak diperlukan dalam lingkungan virtual.

Informasi lebih banyak mengenai JeOS bisa diperoleh dari http://www.ubuntu.com/products/whatisubuntu/serveredition/jeos, terdapat 2 versi yaitu JeOS berbasis server Hardy sebagai rilis LTS dan yang berbasis server Interpid sebagai rilis terbaru. Requirment yang dibutuhkan JeOS sangat kecil bahkan bisa bekerja dengan RAM 128M dan menurut informasi HDD space yang diperlukan juga sangat sedikit.

Untuk deployment server ini saya unduh JeOS dari url berikut http://cdimage.ubuntu.com/jeos/releases/8.04.1/release/, langsung dari canonical sebab saya tidak menemukan file iso JeOS tersebut di foss-id.web.id dan kambing.ui.edu.

sekalian saya dong… pengelola mirror kalo bisa sediain mirror iso image JeOS

Seperti biasa dari web interface VMware server 2 saya create sebuah VM baru dengan CDROM yang menunjuk file iso JeOS tersebut. Boot VM dan saya disambut layar khas instalasi Ubuntu

Bedanya ada tulisan “JeOS”

Instalasi semua sama persis seperti Hardy Heron, bedanya jika kita melihat tahapan instalasi kernel, akan tampak instalasi kernel virtual, artinya kernel yang diinstall sudah dioptimasi untuk bekerja dalam lingkungan virtualisasi.

Selanjutnya setelah server sudah terinstall langkah yang selalu saya lakukan adalah mengubah default entry /etc/apt/sources.list supaya menuju ke foss-id.web.id.

vim /etc/apt/sources.list

Kemudian

:%s/id.archive.ubuntu.com/dl2.foss-id.web.id/g

Jauh lebih kenceng bok!

Setelah itu saya lakukan update terhadap sistem

sudo apt-get update && sudo apt-get upgrade

Jika menggunakan sebuah server tervirtualisasi dengan VMware Server saya melihat adanya peningkatan performance networking yang sangat tinggi jika saya install VMware tools. Tools ini rupanya tidak tersedia secara default dalam distro ini, untuk itu kita perlu install secara manual dengan terlebih dahulu install paket2 untuk build VMware-tools

sudo apt-get install build-essential linux-headers-$(uname -r) psmisc

setelah itu dari web gui VMware server 2 saya klik install vmware tools

kemudian dari console saya mount CD instalasi VMware Tools

mount /media/cdrom0

Copy file instalasi ke /tmp

sudo cp -a /media/cdrom0/VMwareTools*.gz /tmp/

ektrak lalu install

cd /tmp/
sudo tar -xzvf VMwareTools*.gz
cd vmware-tools-distrib/
sudo ./vmware-install.pl

selanjutnya saya reboot VM tersebut, setelah kembali nyala tampilan informasi mengenai VM tersebut akan berbeda

Selanjutnya guest VM tersebut telah siap digunakan.

The following steps tell how it is done…

1. Preparation… I did a some testing a week ago on a local desktop at the office which worked out well… on the first run…

2. Last night I downloaded the latest VMware Server 2.0 tar package from http://www.vmware.com directly to the host using links… and copy – pasted the license to a text file on my notebook… didn’t want to wait for chunky 500 Megs to download over the puny international link… so I went to sleep… this morning my wife wanted to go shopping so we went to Tanah Abang… Hey… its a public holiday… of-course… family comes first

3. Always have a back-out plan… yeah… yeah… yeah… its best practice… with that in mind I can always scp the VM’s to the second VMware server I have at the same data center… transferring the VM’s over the 1GB link would not be too much of a wait… if that does really happen I would have to reduce the RAM of the guest VM’s to allow it to boot… I’m pushing resources here!

4. Done with testing… prepared the necessary files… have a back-out plan… now comes deployment… I halted each VM via ssh-ing into each of them one-by-one… downtime is ticking now…

wisu@orange:~$ sudo halt

then I stopped the VMware service

wisu@ungu:~$ sudo /etc/init.d/vmware stop

after that I extracted the VMware package

wisu@ungu:~$ tar -zxvf VMware-server-2.0.0-122956.i386.tar.gz

Whoops! I should of done that before hand… it would of reduced down time… well … after waiting I navigate to the install files

wisu@ungu:~$ cd vmware-server-distrib/

then ran the installation

wisu@ungu:~$ sudo ./vmware-install.pl

VMware detected the older version… I pretty much accepted the defaults of each question specially when it said that it would use the existing network settings… the only exception is that I specified a specific user as the VMware Server administrator… then when it prompted for a license I copy-pasted the code from the text file i saved last night… and the installation ran as previously tested… VMware started all the VM services… and the installation said the magic word… Successfully bla… bla.. bla…

5. Next I had to change the firewall settings to allow me access to the secure web interface… which was tcp port 8333…

6. Then I accessed the web interface and it said that only one VM was alive… well it does boot the virtual machine one at a time… I must be early…

7. I could say that the upgrade was complete… but I had to test the console as well… turned out that the firefox addon was different from the one i used at the testing environment… thus I had to wait for the 18.9 M plugin to download over speedy…

8. While waiting for the download, I ssh-ed to each host and verified each service was up and running…

9. Finally the download was complete and I could access one console…

OK… the stopwatch said 34 minutes downtime… I could of done it in lesser down time… but over all I still have a good enough report to each client… more important is… I have plenty of time to play with the kids… got yoyo tricks to try out…

Instalasi di Hardy Heron gampang banget… tinggal install beberapa aplikasi dan kernel headers yang dibutuhkan untuk nge-build…

sudo apt-get install linux-headers-`uname -r` build-essential xinetd

download aplikasinya dari

https://www.vmware.com/freedownload/p/download.php?product=server20

untuk ubuntu bisa pilih format tar.gz… sebelumnya anda harus register untuk mendapatkan license key dan download link nya… extract

sudo tar -zxvf VMware-server-2.0.0-116503.i386.tar.gz

Lalu install

sudo ./vmware-install.pl

Isi lokasi install, setting networking dll.. kemudian masukkin license keynya… dan VMware server 2 terinstall dengan baik… dan menginformasikan bahwa sudah berjalan…

Selanjutnya port 8333 server saya buka biar bisa akses Web GUI nya.. dan seperti tertulis di banyak situs Aplikasi ini tidak lagi mengikut sertakan VMware console terinstall… semua dilakukan melalui web browser…

Saat power on VM, dan ingin mengakses console… Firefox akan menginstall plugin… yang gedhenya 19 MB…

Setelah terinstall restart firefox… dan tampilannya…

Akses console cukup nyaman walaupun server berada di gedung cyber… dan koneksi internet di kantor 512 keroyokan…

Resolving requires me to delete 2 *.WRITELOCK files within the same directory as the *.vmdk file…

$ ls
564d77ac-9f7e-2227-ad4a-45fc12749f5f.vmem
564d77ac-9f7e-2227-ad4a-45fc12749f5f.vmem.WRITELOCK
nvram
vmware-0.log
vmware-1.log
vmware-2.log
vmware.log
Windows XP Professional-f001.vmdk
Windows XP Professional-f002.vmdk
Windows XP Professional-f003.vmdk
Windows XP Professional-f004.vmdk
Windows XP Professional-f005.vmdk
Windows XP Professional-f006.vmdk
Windows XP Professional-f007.vmdk
Windows XP Professional-f008.vmdk
Windows XP Professional.vmdk
Windows XP Professional.vmdk.WRITELOCK
Windows XP Professional.vmsd
Windows XP Professional.vmx

after that starting the virtual machine from the VMWare MUI seems to do the trick…

Server ini jalan diatas Virtual Infrastructure… sebuah mesin AMD Athlon 64Bit dengan RAM 2GB HDD 2x 80GB… secara resource mesin ini sangatlah berlebih…

Jadi jika anda butuh sebuah dedicated server, mungkin anda bisa mencoba sebuah Virtual Machine yang jalan di server saya… tentunya dengan harga yang menarik…
