Cara Mengetahui Type Memory Di Linux
Untuk mengetahui memory yang ada di CPU kita banyak caranya, anda bisa coba
$ cat /prog/meminfo
Bisa juga dengan lshw, tapi harus install dulu
$ sudo apt-get install lshw
$ sudo lshw
| *-memory | ||
| description: System Memory
physical id: 1b slot: System board or motherboard size: 1GiB |
||
| *- | bank:2 | |
| description: DIMM 533 MHz (1.9 ns)
product: None vendor: None physical id: 2 serial: None slot: A2 size: 1GiB width: 64 bits clock: 533MHz (1.9ns) |
terlihat bahwa CPU saya terinstall memory DDR 533 1GB lokasinya di bank:2
Bisa juga dengan dmidecode, caranya
$ sudo apt-get install dmidecode
$ sudo dmidecode –type 17
# dmidecode 2.9
SMBIOS 2.3 present.
| Handle 0x001E, DMI type 17, 27 bytes

Install Oracle 10g On Centos 5.5
Udah lama pengen belajar database oracle 10g, coba install database oracle 10g walaupun sudah ada 11g, banyak yang mengatakan ini database canggih saya sendiri belum pernah coba emang ga bisa alias masih belajar, khusus di Linux tahapan installasi lebih rumit, tapi cukup menantang, ya coba aja kalo ga di coba ga bakalan tau.
Sedikit tentang oracle, oracle adalah perusahaan besar yang di belakangnya banyak mengeluarkan produk database dan software ERP kelas Enterprise dan sekarang perusahaan ini udah jadi rasaksa setelah membeli Sun Microsystem yang di dalamnya ada Sun Sparc jajaran server kelas atas, Solaris, Java, PHP dan MySql. Kenapa oracle ngotot mau membeli Sun Microsystem satu di antaranya adalah Java yang ada di sun, siapa yang ga kenal dengan java bahasa pemograman ini sudah masuk ke berbagai device dari handphone sampai software kelas enterprise menggunakan java, dan oracle 10g sendiri di tulis dengan bahasa pemograman java, hampir bisa di bilang oracle merajai segment kelas enterprise dan baru-baru ini lagi ribut ama google gara-gara android.

Install Adempiere 360LTS On CentOS 5.5
Dengan dukungan komunitas Adempiere berkembang cukup cepat, belum lama kita install Adempiere 354a tapi sudah ada rilis terbaru yaitu Adempiere 360LTS
Banyak pebaikan yang dilakukan termasuk dari cara install dan kita akan coba install Adempiere 360LTS dengan CentOS 5.5
Download jdk1.6.0_21 disini
Download Adempiere disini
Lalu letakan dan extrak di /opt
Install java
# chmod +x jdk-6u21-linux-i586.bin
# ./jdk-6u21-linux-i586.bin
# ln -sf /opt/jdk1.6.0_21/bin/java /usr/bin/
# java -version
java version “1.6.0_21″

Update Adempiere 360LTS
Masih dalam proses pembelajaran Adempiere
Saya baru saja install Adempiere 360LTS di CentOS 5.5 yang jadi pertanyaan kenapa harus pake Adempiere 360LTS dan CentOS/Ubuntu terbaru?
- Bisa saja kita install Adempiere 345a hanya saja kita harus lakukan patch dan patchnya cukup banyak dan cara installnya juga harus secara berurutan ini jadi cukup merepotkan.
- Bisa saja kita install dengan Ubuntu 8.04/CentOS 5.2 masalahnya nanti Adempiere akan minta upgrade database postgresql yang terbaru jadi ini juga cukup merepotkan
jadi saya putuskan untuk install Adempiere 360LTS di Distro Linux terbaru dan pilihan saya jatuh ke CentOS 5.5
untuk masalah setting masih sama dengan versi yang terdahulu jadi bisa ikuti di sini
Untuk melakukan update Adempiere 360LTS kita harus mendownload patch di sini
Setelah kita download extrak dan letakkan update
# mv 740_BF3010957.sql /opt/Adempiere/lib/
# mv 20100618_patches_360_12674.jar /opt/Adempiere/lib/
Jalankan patch sebagai user postgres
# su - postgres
-bash-3.2$ psql -U adempiere -f /opt/Adempiere/lib/740_BF3010957.sql
UPDATE 12
Selamat mencoba
Lebih Lanjut Tentang VirtualBox
Lebih lanjut tentang VirtualBox
Melakukan uji coba kadang membuat kita membutuhkan beberapa Distro Linux OS yang berbeda, mau ga mau kita harus install dari awal.
Tetap jika kita ingin melakukan testing pada 2 distro yang sama misalnya Ubuntu 8.04, kita tidak perlu untuk meng-install dari awal cukup lakukan Cloning pada image Ubuntu tersebut karena jika kita lakukan copy image saja dan merubah nama image itu tidak cukup karena image ubuntu tersebut masih memiliki UUID yang sama
Jalankan perintah list vms untuk melihat list GuestOs yang terinstall di Host kita Read the rest of this entry »
My NoteBook Benq S53
Sudah 3 tahun sejak 2007 saya gunakan laptop Benq S53 laptop ini cukup kuat dan stabil, bahkan saya banyak belajar dari mengandalkan laptop ini.
Ini adalah Spec Benq S53
| Name | BenQ Joybook S53 |
| Processor | Intel Pentium-M 745 1.8GHz |
| Screen | 13” WXGA |
| RAM | 512MB |
| HDD | 60GB |
| Optical Drive | DVD+-RW |
| Graphics | Intel Graphics Media Accelerator 900 |
| Network | 10/100 Ethernet, Intel 2200 802.11g Wireless |
| Other | 2 x USB2.0, 1 x Firewire |
Saya install dengan Ubuntu dari 7.04 sampai yang terakhir 10.04 semua terdeteksi dengan baik.
Benq S53 saya telah saya upgrade
RAM 512MB ke 2GB
Hardisk 60GB ke 160 GB walaupun kata teknisinya Max 80 Read the rest of this entry »
Install Mail Server Zimbra di Ubuntu 8.04
Install Mail Server Zimbra On Ubuntu 8.04
Pada tutorial sebelum kita sudah membuat DNS sever di Fedora 7 dan sekarang kita lanjutkan untuk membuat Mail Server dengan Zimbra, OS yang saya gunakan adalah Ubuntu 8.04.
Untuk keperluan Zimbra kita juga harus setting DNS-nya, kita tetap memanfaatkan DNS Server yang sudah ada dan kita hanya memerlukan DNS Forwarders berikut caranya
Masih mengandalkan Laptop Benq S53 dengan memory 2GB, Hardisk 160GB dan tidak lupa aplikasi favorit VirtualBox saya jalankan Fedora 7 sebagai DNS dengan memory 256MB dan Ubuntu 8.04 sebagai Mail Server Zimbra dengan memory 512MB. Read the rest of this entry »
Merubah Run Level Ubuntu 8.04
Masih seputar virtualisasi
Untuk kebutuhan testing kadang-kadang perlu untuk mencoba di beberapa distro yang berbeda.
Karena keterbatasan memory maka beberapa Guest OS di beri Ram yang minim yakni cuma 256MB, oleh karena itu beberapa service dan X Windows harus di non aktifkan walaupun sebenarnya bisa saja langsung menginstall Ubuntu Server .
Di Linux istilah ini di sebut adalah merubah run level seperti yang di jelaskan disini dan disini.
Kali ini saya coba untuk merubah default run level di ubuntu 8.04
$ ls -al /etc/rc3.d/ | grep gdm
lrwxrwxrwx 1 root root 13 2010-07-13 17:16 S30gdm -> ../init.d/gdm
ternyata /etc/init.d/gdm itu di buatkan symbolik link ke /etc/rc3.d/S30gdm
jadi lakukan perintah berikut
$ sudo mv /etc/rc3.d/S30 /etc/rc3.d/xS30gdm
Buat file inittab
$ sudo vim /etc/inittab
id:3:initdefault:
Sekarang coba reboot, silakan mencoba
Setting Bridge VirtualBox Di Ubuntu 10.04
Sudah menjadi ritual upgrade OS Ubuntu jika versi LTS rilis dari 8.04 ke 10.04 karena sudah di siapkan partisi khusus maka langsung saja install.
Saya lebih memilih clean install dari pada upgrade karena Os lebih bersih dan sistem yang lama biarkan berjalan.
Proses install relatif mudah kendala ditemukan ketika kita harus mengupgrade beberapa aplikasi yang ada. Salah satu aplikasi favorit saya adalah VirtualBox untuk Virtualisasi OS karena kebutuhan testing jaringan.
Kenapa saya pilih VirtualBox karena lebih mudah settingnya walaupun boros resources
untuk lebih jelas tentang Virtualisasi disini jelaskan Read the rest of this entry »
