Remote Desktop Ubuntu dari Lubuntu

Setting Ubuntu yang akan di remote, kebetulan target adalah ubuntu 10.04 LTS.

Selesai mengkonfigurasi di desktop target, sekarang tinggal otak-atik di Lubuntu. Beberapa aplikasi yang bisa di install di Lubuntu.

unaisah@Aspire-3620:~$ sudo apt-get install xvnc4viewer

Untuk menjalankan remote desktop bisa dilakukan dengan cara ini.

unaisah@Aspire-3620:~$ xvnc4viewer -fullscreen 192.168.10.100:0

Berikut hasil penampakannya:

Install Wordpress

Pertama : download wordpress

Kedua : ekstrak file.zip

unaisah@Aspire-3620:~/Downloads$ unzip wordpress-3.3.1.zip

Ketiga : pindahkan hasil ekstrak file ke /var/www

unaisah@Aspire-3620:~/Downloads$ sudo mv wordpress /var/www/ 

Keempat : buat database untuk wordpress

mysql> create database wordpress;

Kelima : edit file wp-config-sample.php 

unaisah@Aspire-3620:/var/www/wordpress$ sudo nano wp-config-sample.php 

/ ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');
/** MySQL database username */
define('DB_USER', 'root');
/** MySQL database password */
define('DB_PASSWORD', 'password');
/** MySQL hostname */

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');
/** The Database Collate type. Don't change this if in doubt. */
define('DB_COLLATE', '');

Keenam : ganti wp-config-sample.php menjadi wp-config.php

unaisah@Aspire-3620:/var/www/wordpress$ sudo mv wp-config-sample.php wp-config.php

Ketujuh : jalankan instalasi dengan membuka web broswser kesayangan anda gan ketik localhost/wordpress

Install DHCP server Debian

Kali ini gw akan lebih sering maenan server, pertama-tama gw mau coba maenan DHCP server.
root@debian:~# apt-get install dhcp3-server

Tempat setting

root@debian:~# nano /etc/dhcp/dhcpd.conf

Kira-kira isinya sebagai berikut:

ddns-update-style none;

option domain-name "example.org";

#option domain-name-servers 145.253.2.75, 193.174.32.18;

option domain-name-servers ns1.example.org, ns2.example.org;

default-lease-time 86400;

max-lease-time 604800;

authoritative;

subnet 192.168.10.0 netmask 255.255.255.0 {

        range 192.168.10.200 192.168.10.229;

        option subnet-mask 255.255.255.0;

        option broadcast-address 192.168.10.255;

        option routers 192.168.0.15;

}

Kemudian restart DHCP server
root@debian:/etc/dhcp# /etc/init.d/isc-dhcp-server restart 

Install LAMP

Ketika instalasi debian gw udah install webserver, sekarang tinggal install PHP, MYSQL.

root@debian:~# apt-get install apache2 php5 libapache2-mod-php5
root@debian:~# apt-get install mysql-server mysql-client php5-mysql
root@debian:~# apt-get install phpmyadmin

Jreng....

Klik Pada Mouse Pad Gak Jalan

Yes.....

Akhirnya kesampean juga install debian, debian yang gw install versi 6.0.4, proses instalasi gak jauh beda sama ubuntu (maklum bapaknye ubunu). Setelah install eh klik mouse pad kagak jalan, cari-cari ke sana kemari, disuruh buat file xorg.conf lah itu lah, eh malah kagak bisa masuk gui. Ternyata cukup mudah tinggal klik System >Preferensi >  Tetikus > pilih Enable mouse clicks with touchpad (milih bahasa terlanjur bahasa indonesia)

Wah ternyata untuk mengambil tangkapan layar harus menambahkan list repository dan menginstall gnome-screenshot

Caranya? gampang...

Menambah repository

unaisah@debian:~$ su

Password: 

root@debian:/home/unaisah# gedit /etc/apt/sources.list

Tambahkan  list ini:

deb http://repo.ugm.ac.id/debian squeeze main non-free contrib

deb-src http://repo.ugm.ac.id/debian squeeze main non-free contrib

apt-get update

apt-get gnome-screenshot

Berikut tangkapan layarnya:

Membuat Startup Disk Creator

Entah kenapa, gw pake Startup Disk Creator bawaan di ubuntu 10.04.3  tuk install debian 6 ke FD gak bisa boot waktu mau install lewat FD. Padahal udah proses pembuatan udah 100% berhasil.

Penasaran, gw coba aja pake bawaan Startup Disk Creator (l)ubuntu 11.10, semua berjalan lancar.....

Startup Disk Creator

Secara default Lubuntu tidak menyertakan aplikasi Startup Disk Creator, aplikasi ini digunakan untuk membuat startup dari flash disk. Kita bisa menggunakan synaptic atau terminal untuk instalasi.

sudo apt-get install usb-creator-common usb-creator-gtk

Setelah selesai instalasi, aplikasi ini berada di Menu > System Tools

Have fun

Setting Pada LTSP 32 Bit

Jika kita menginstal ubuntu versi desktop kemudian ingin mendginstal LTSP, berikut cara dan sedikit setting-nya.

Buat IP static di komputer server LTSP

sudo gedit /etc/network/interfaces

Kira-kira isinya seperti ini (sesuaikan dengan konfigurasi jaringan yang ada)

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
 address 192.168.10.18
 netmask 255.255.255.0
 network 192.168.10.0
 broadcast 192.168.10.255
 gateway 192.168.10.15

Restart untuk memperbaharui perubahan

sudo gedit /etc/init.d/networking restart

Install LTSP

sudo apt-get install ltsp-server-standalone

Sesuaikan konfigurasi dhcp-sesrver

sudo gedit /etc/ltsp/dhcpd.conf

Kira-kira isinya seperti ini

# Default LTSP dhcpd.conf config file.

authoritative;

subnet 192.168.10.0 netmask 255.255.255.0 {
    range 192.168.10.20 192.168.10.250;
    option domain-name "ltsp";
    option domain-name-servers 192.168.10.1;
    option broadcast-address 192.168.10.255;
    option routers 192.168.10.15;
#    next-server 192.168.10.1;
#    get-lease-hostnames true;
    option subnet-mask 255.255.255.0;
    option root-path "/opt/ltsp/i386";
    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";
    }
}

Setting ethx pada bagian ini

 
# Defaults for dhcp initscript
# sourced by /etc/init.d/dhcp
# installed at /etc/default/dhcp3-server by the maintainer scripts

#
# This is a POSIX shell fragment
#

# On what interfaces should the DHCP server (dhcpd) serve DHCP requests?
#       Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACES="eth0"

Apabila melakukan perubahan-perubahan IP, lakukan perintah ini

sudo ltsp-update-sshkeys && sudo ltsp-update-image

Alhamdulillah Jalan LTSP nya

Alhamdulillah akhirnya LTSP berjalan dengan baik di client dengan booting melalui NIC

Fiuh...... next ngoprek LTSP 12.04

Menjalankan Klien LTSP di virtualbox

Berikut cara setting virtualbox agar klien LTSP berjalan di virtualbox.

yups... berhasil

Install LTSP

Setelah mumet cari dokumentasi/tutorial LTSP, akhirnya gw memutuskan untuk menggunakan ubuntu alternate 10.04 32 bit, karena cara instalasinya mudah, hanya memasukkan cd installer kemudian pada menu install tekan F4 kemudian pilih Intall an LTSP Server.

Lanjutkan proses instalasi hingga selesai dengan konfigusrasi-konfigurasi yang ada. Setelah selesai tahap instalasi, seharusnya LTSP server sudah jalan. Untuk mengetesnya bisa gunakan virtualbox untuk menjalankan client LTSP.

Install VirutalBox

Bahasan ini sudah banyak yang bahas, oleh karena itu gw singkat aja bahasannya.

download download virtualbox, pilih sesuai distro yang dipakai dan arsitekturnya.

Kemudian install, dengan double klik file virutalboxxx.deb atau melakukan

sudo dpkg -i virutalboxxx.deb && sudo apt-get install -f

Kalo gak ada masalah, si virtualbox udah ter-install dengan benar.

Selanjutnya pasang LTSP

Tangkapan Layar Ubuntu 10.04.3 64 bit

Akhirnya kelar juga install ini ubuntu. Sengaja ini ubuntu gak diapa-apain yang penting secara fungsionalitas terpenuhi. Berikut tangkapan layarnya.

Selanjutnya pasang virtualbox

Install ubuntu 10.04.3 64 bit

Gara-gara lagi musim razia nongol lagi, jadi harus nyediain satu server LTSP tuk ditaro di kantor cabang. Kemaren sempet install ubuntu 11.10 i386 di satu pc yang akan dijadikan server, karena RAM 4 GB jadi harus install kernel pae (maksudnya biar si RAM yang 4 GB itu bisa dibaca semua). Info cari info..... katanya LTSP di ubuntu 11.10 berat (belom nyoba sih) jadi harus install di ubuntu 10.04.3 LTS.

Sengaja install yang 64 bit, biar gak usah install si kernel pae lagi, sekalian nyoba ngerasain ubuntu 64 bit.

Pengaturan dan proses instalasi sama seperti install ubuntu yang lain, hanya pada pemilihan untuk partisi, gw pilih semua HDD tanpa dibagi-bagi untuk / (root), swap dan seterusnya.
