Beberapa error dalam install joomla...

Beberapa kali kita sering mengalami error ketika menginstall joomla ( installer, komponen, modul ataupun template). Biasanya pesan yang muncul adalah :
JInstaller: :Install: Cannot find Joomla XML setup file
Berikut beberapa langkah yang perlu disesuaikan untuk mengatasinya :

1. Setting php.ini diserver perlu disesuaikan diantaranya : memory_limit = 50M  post_max_size = 10M file_uploads = On upload_max_filesize = 10M  (Letak file php ini tergantung OS server anda masing-masing, di apache ubuntu letaknya di :  /etc/php5/apache2/php.ini
2. Folder dalam joomla harus kita set Writeable agar saat menginstall berjalan baik. Folder tersebut adalah : tmp, modul, component, template, language.
3. Jangan Lupa untuk merestart service apache untuk perubahan konfigurasi php.

Selamat berjuang ....

Cloning antar hardisk di linux tanpa bantuan software tambahan

mungkin judul saya kurang tepat, maksud di sini adalah mengunakan software yg sudah include ada di linux jadi tidak perlu repot lagi mau install software atau bikin pakai software khusus.

sebenarnya lahngak ini sudah banyak di jelaskan di internet jadi tulisan ini saya tulis waktu pada saya kondisi kepepet di mana pada saat saya memaintenance warnet saya lupa membawa flashdisk 1 buah pun yg biasa saya gunakan flashdisk itu untuk software cloning saya yaitu clonezilla.

cara ini juga bisa di gunakan untuk menuliskan file .img ke flashdisk atau ke hardisk.

cara menulis file .img ke flash disk atau hardisk.

dd if=/lokasi_file_img/file.img of=/dev/hardisk_flashdisk

contoh:

dd if=/home/sa3o/pfsense.img of=/dev/sdb

kalau cara cloning :

dd if=/dev/hardisk_asal(bisa hardisk komp kita sendiri) of=/dev/hardisk_tujuan

contoh:

dd if=/dev/sda of=/dev/sdb

Sekian  .

TIPS & TRIK : Webmin Tidak Mendeteksi isc-dhcp-server

Di ubuntu 12.04, webmin tidak mendeteksi adanya isc-dhcp-server. Untuk memperbaiki masalah ini, replace file  /etc/webmin/dhcpd/config dengan isi file sebagai berikut :

start_cmd=/etc/init.d/isc-dhcp-server start

lease_file=/var/lib/dhcp/dhcpd.leases

dhcpd_path=/usr/sbin/dhcpd

display_max=100

group_name=0

lease_tz=0

lease_sort=0

interfaces_type=debian

show_mac=0

stop_cmd=/etc/init.d/isc-dhcp-server stop

dhcpd_conf=/etc/dhcp/dhcpd.conf

pid_file=/var/run/dhcpd.pid

restart_cmd=/etc/init.d/isc-dhcp-server restart

desc_name=0

show_ip=0

dhcpd_nocols=5

add_file=

hostnet_list=

version=

dhcpd_version=4.1.1

dhcpd_size=700320

dhcpd_mtime=1279996769

Setelah isi file /etc/webmin/dhcpd/config Anda edit, refresh modul webmin, dan muncullah DHCP di modul Server.

# Separate multiple interfaces with spaces, e.g. "eth0 eth1".
INTERFACES="eth0"
________________________________________________

Kemudian File di /etc/dhcp/dhcpd.conf sebagai berikut :
________________________________________________

#
# Sample configuration file for ISC dhcpd for Debian

log-facility local7;
# A slightly different configuration for an internal subnet.

WEBMIN : Installing on Debian

If you are using the DEB version of webmin, first download the file from the downloads page, or run the command :wget http://prdownloads.sourceforge.net/webadmin/webmin_1.580_all.debthen run the command :dpkg --install webmin_1.580_all.debThe install will be done automatically to /usr/share/webmin, the administration username set to root and the password to your current root password. You should now be able to login to Webmin at the URL http://localhost:10000/. Or if accessing it remotely, replace localhostwith your system's IP address.

If Debian complains about missing dependencies, you can install them with the command :apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions pythonIf you are installing on Ubuntu and the apt-get command reports that some of the packages cannot be found, edit /etc/apt/sources.list and make sure the lines ending with universe are not commented out.

Some Debian-based distributions (Ubuntu in particular) don't allow logins by the root user by default. However, the user created at system installation time can use sudo to switch to root. Webmin will allow any user who has this sudo capability to login with full root privileges.

If you want to connect from a remote server and your system has a firewall installed, see this page for instructions on how to open up port 10000.

Using the Webmin APT repository

If you like to install and update Webmin via APT, edit the /etc/apt/sources.list file on your system and add the lines :deb http://download.webmin.com/download/repository sarge contrib
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contribYou should also fetch and install my GPG key with which the repository is signed, with the commands :cd /root
wget http://www.webmin.com/jcameron-key.asc
apt-key add jcameron-key.ascYou will now be able to install with the commands :apt-get update
apt-get install webminAll dependencies should be resolved automatically.

Supported Debian-based Distributions

Webmin has been tested on all regular Debian releases, Ubuntu Linux, and derivatives like Xandros and APLINUX.

Source Packages

The files needed to build the Debian package are deb/webmin_1.580.dsc,deb/webmin_1.580.diff, and webmin-1.580.tar.gz .
