MysqlPasswordReset

Are you looking at this page because you cannot access the mysql server installed on your pc/server when you were trying to see if it works well? Or do you receive error messages like the following? :

ERROR 1045: Access denied for user: 'root@localhost' (Using
password: NO)

or

ERROR 1045: Access denied for user: 'root@localhost' (Using
password: YES)

To resolve this problem ,a fast and always working way is the “Password Resetting” .

How can I reset my MySQL password?

Following this procedure, you will disable access control on the MySQL server. All connexions will have a root access. It is a good thing to unplug your server from the network or at least disable remote access.

To reset your mysqld password just follow these instructions :

• Stop the mysql demon process using this command :

  •    sudo /etc/init.d/mysql stop

• Start the mysqld demon process using the –skip-grant-tables –user=root option with this command

  •    /usr/bin/mysqld --skip-grant-tables --user=root

In Dapper, /usr/bin/mysgld… did not work. However, mysqld --skip-grant-tables did.

• start the mysql client process using this command

  •    mysql -u root

• from the mysql prompt execute this command to reset/update your password

  •    SET PASSWORD FOR root@'localhost' = PASSWORD('password');

• If you have a mysql root account that can connect from everywhere, you should also do:

  •    UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';

• Alternate Method:

  •    USE mysql
       UPDATE user SET Password = PASSWORD('newpwd')
       WHERE Host = 'localhost' AND User = 'root';

• And if you have a root account that can access from everywhere:

  •    USE mysql
       UPDATE user SET Password = PASSWORD('newpwd')
       WHERE Host = '%' AND User = 'root';

For either method, once have recieved a message indicating a successful query (one or more rows affected), flush privileges:

FLUSH PRIVILEGES;

Then stop the mysqld process and relaunch it with the classical way:

sudo /etc/init.d/mysql start

When you have completed all this steps ,you can easily access to your mysql server with the password you have set in the step before. An easy way to have a full control of your mysql server is phpmyadmin (www.phpmyadmin.net), software made in php that can give you a web interface that can be very usefull to people that havent got a lot of confidence with bash .To install phpmyadmin on you server you will need to have 4 things:

• web server apache
• php
• mysql server/mysql client installed
• php_mysql support for apache

All packages can be found browsing synaptic.

Another way, purge

I also had some problems with mysql just not accepting my password. I tried the other way aswell and it just ended up being difficult. I had not been able to use mysql so it was empty anyway. If this is also your case you may opt for the PURGE way. This removes every file related to mysql. Depending on your installation the packages might be diffrent, mysql-server in 6.10 is called mysql-server-5.0 as an example.

USE THIS AS A LAST RESORT METHOD, YOU WILL LOSE ALL YOUR MYSQL DATA

sudo apt-get --purge remove mysql-server mysql-common mysql-client

sudo apt-get install mysql-server mysql-common mysql-client

In the next step be sure to chance the your-new-password with the password you want!

mysqladmin -u root password your-new-password
sudo /etc/init.d/mysql restart

mysql -u root -p

You should now be logged in as root. Make sure to notedown your password! Thanks to Illuvator for posting this method in the ubuntu forum.

Installing a Jabber server

This describes how to install a jabber server on ubuntu linux (6.06), but should work pretty well on just about any distro. I’ve used wildfire, becuse it is the most feature complete, and its as easy to install as it gets. Its java based, so you’ll need to have java installed properly first.

Make sure you have java installed (java -version), if not get it and install it

dhcp server

Artikel ini copast dari fedora.or.id author:rito
DHCP atau Dynamic Host Configuration Protocol, merupakan salah satu mekanisme pemberian IP pada komputer host atau client secara otomatis. Mekanismenya adalah menggantikan peran administrator jaringan dalam, terutama saat memasukkan IP Address di setiap komputer Client. Prinsip kerjasanya kurang lebih adalah sebagai berikut, pada saat Server DHCP aktif, maka server DHCP menyediakan range IP pada kelas tertentu, sesuai dengan aturan yang ditetapkan oleh admin. Kemudian, pada saat komputer client yang terhubung ke jaringan aktif, sistem operasi akan mencari ke DHCP server, apakah ada IP yang bisa direservasi. Jika ada, maka Server DHCP akan memberikan IPtersebut.
Pada DHCP, lama waktu IP yang diberikan pada setiap komputer bisa dibuat dinamis, artinya setelah pada waktu tertentu, maka IP yang ada pada komputer client akan habis masa penggunaannya. Ini disebut lease IP. Ada juga yang sifatnya, IP tersebut tetap berada di komputer client, selama kartu jaringannya tidak rusak tentunya.

Nagios Setup On Ubuntu

Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external “plugins” which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser.

Ceritanya aku mau install ulang ubuntu gue. Dan di Ubuntu lama itu udah banyak terinstall program tambahan kaya mc, inkscape, koffice, dst. Dan…sayang kan kalau setelah fresh install ubuntu terus kita mesti install aplikasi tambahan lagi satu demi satu dengan mengambil repo yang di internet. Mendingan cache bekas installan di ubuntu lama kita manfaatkan. Kita jadikan local repossitory. Gimana? Ide bagus kan? Okeh mari kita mulai bikinnya.

Install Ubuntu server kok lamaaaaaaaa banget yah ???

Peristiwa ini ane alami saat sebuah router dari klien perusahaan sedang ngadat alias error abizzz dan harus di install ulang.

OS yang lama memakai Fedora, karena pada saat tsb ndilalah tidak ada satupun CD Fedora yang entah kemana barangnya dan hanya ada CD Ubuntu server 7.10 Hardy maka tak ayal lagi harus pakai CD Ubuntu yg ada.
