How To Update Linux Kernel In Ubuntu - Manually

1. You must download appropriate ubuntu kernel release from
   http://kernel.ubuntu.com/~kernel-ppa/mainline/  (in this case I am download 2.6.32 kernel version for update)
    
2. Download this 3 file types (it will depend on your processor architecture - my one is Intel 32bit - then i am downloaded i386 file types)
   
   (your downloaded file must contain this names as file name)
   
   i.   linux-headers-??????????_all.deb
   ii.  linux-headers-??????????_i386.deb
   iii. linux-image-????????????_i386.deb
   
   Ex: (my downloaded files in order to above file naming criteria)
   
   linux-headers-2.6.32-020632_2.6.32-020632_all.deb
   linux-headers-2.6.32-020632-generic_2.6.32-020632_i386.deb

Install MySQL In Ubuntu On VMware And Connect Through The Host Pc (windows or any host pc)

This article explain how to install MySql 5.5 with Ubuntu 12.04 on VMware (VMware Workstation 8.0.1) and connect through the virtual pc to access the MySql databases in Host pc (Windows or what ever os on host pc). 

1.Install MYSQL On Ubuntu 12.04

sudo apt-get install mysql-server  

(make sure you are log in as root user,fast internet connection help to download package's correctly.if network connection slow,then download packages may be corrupted!)

2.Install MYSQL Workbench

sudo apt-get install mysql-workbench 

sudo service mysql restart (this 'sudo' command not recommend if you are log in as root user.)

3.Host pc network connection parameters:

Disable other network connection as below.

figure 1.0

1.Goto VMware network adapter properties

2.Checked VMware Bridge Protocol.

3.Select appropriate ip range. VMware set default IP range

something like 192.168.###.### 

eg: 192.168.137.1 <- and="" be="" equal="" font="" guest="" ip="" must="" nbsp="" ost="" range="">

4.Guest(VMware - Ubuntu) pc network connection parameters:

1.Goto Network settings (top right corner)

2.Goto Edit Connections...

3.Select Wired Connection1 and click edit button

4.Select IPv4 Settings and Set Method as Automatic (DHCP)

5.Don't set DHCP client id or routes

6.Click available to all users ,then save.

Check whether ip address in a same range(first 9 digits must be same).(host ip range 192.168.137.###) guest must be 192.168.137.###)

To check above connection information's click network connection icon on top right corner of desktop(ubuntu) and select connection information as below.

figure 2.0

5.Create MySQL user (type these command in MYSQL command terminal)

open terminal and type mysql -u root -p

then type your root mysql password 

then type 

create user 'username'@'192.168.137.218' identified by 'your-new-password'

eg:

create user 'abc'@'192.168.137.218' identified by 'abc123'

create user 'abc'@'%' identified by 'abc123';

5.1 Replace username with your new user name to given and insert new password in to 'your-new-password'

5.2 Make sure your ip address is should be ubuntu-pc's IP address

eg: 192.168.137.218 in figure 2.0

5.3 Then grant privileges to above user

grant all privileges on *.* to 'abc'@'%' with grant option;

5.4 Then flush the privileges

flush privileges;

5.5 Restart mysql services

type this

service mysql restart;

5.6 Then goto host pc (your windows pc)

used any MySQL GUI or command line program and set the particular parameters.

eg:

mysql user: abc

host ip   : 192.168.137.218 (ubuntu-pc ip address)

password  : abc123

Thats all......Have FuN.....




------------ SOME USEFULLY COMMANDS ON UBUNTU -----------


(shell prompt type following command)

To login as root user in mysql
mysql -u root -p

To login with host name
mysql -u root -h myserver-sever.com -p

To Login with host ip address
mysql -u root -h 192.168.137.218 -p

To restart mysql services:
service mysql restart

To stop mysql services:
service mysql stop;

To start mysql service
service mysql start

create user ('%' mean any host )
CREATE USER 'freevbs'@'%' IDENTIFIED BY 'passpass';

Granted all the privileges to user freevbs
grant all privileges on *.* to 'freevbs'@'%' with grant option;

To flush privileges (alredy login in mysql )
flush privileges;

try login with freevbs
mysql -u freevbs -p;

onece you login you can check users
SELECT USER(),CURRENT_USER();

VMWare Tool Installation for Ubuntu

#Mount the CD drom 
sudo mkdir /mnt/cdrom

sudo mount /dev/cdrom /mnt/cdrom

#Run this command to find the exact name of the VMware Tools bundle; the file name varies depending on your version of Fusion:
ls /mnt/cdrom

#Extract contents of cdrom to tmp directory
tar -zxvf /mnt/cdrom/VMwareTools-.tar.gz -C /tmp/

Note: is the version discovered in the previous step which at the time of writing was VMwareTools-8.3.7-341836.tar.gz

#now move into the vmware tools directory in tmp directory. 
cd /tmp/vmware-tools-distrib/

#Run the installer  with the -d switch to accept defaults.
sudo ./vmware-install.pl -d

Enabling the root account in ubuntu

sudo -i

To enable the Root account (i.e. set a password) use:

sudo passwd root

How to install a software in Ubuntu

There are many different kinds of Linux package files. Most of these are associated with the package managers of specific Linux distributions. Examples are Debian Package files (.deb files), RPM Package Manager files (.rpm files), Tarballs (.tar files) and .run files.
This section deals with installing these single files.

	It is not guaranteed that these files will be compatible with your system and you will not receive security updates if you install these files. For these reasons, if you wish to install a program, always use a native Ubuntu package of the application available through a package manager, if there is one available.

Installing/uninstalling .deb files

These files are Debian packages. The package files associated with Ubuntu have the .deb suffix because of Ubuntu's close relations with the Debian GNU/Linux distribution. You will need administrative privileges to install a .deb file. See Administrative Tasks for more details.
To install a .deb file, double-click on it. If you prefer using the Terminal, enter:

sudo dpkg -i package_file.deb

You can use your package manager to uninstall a .deb file once it has been installed. Alternatively, enter the following in a Terminal:

sudo dpkg -r package_name

Converting .rpm files to .deb files

Another type of package is the Red Hat Package Manager (RPM) file. These have the .rpm suffix. It is not recommended to install these on an Ubuntu system. In almost all cases, a native Ubuntu .deb package is available. However, if absolutely necessary, an .rpm file can be converted to a .deb package using the alien application. The resulting .deb file can be installed as described above.
To convert an RPM into a .deb:

1. Install the alien package.
   
2. In a Terminal, enter:
   

   sudo alien package_file.rpm

   
   

Installing tarballs

Files with the .tar, .tgz, .tar.gz or .tar.bz2 suffix are package files known as tarballs, and are widely used in Linux and Unix to package software. Tarballs can also be used to archive and compress other files.
If there is no native Ubuntu package available in any of the Ubuntu repositories, you can use the command line to install or uninstall the tarball file.
The first step will be to uncompress and extract the tarball. If it is a .tgz or a .tar.gz, in a Terminal enter:

tar xfvz tarball_name

Then it will be necessary to follow the instructions that come with the package. These are generally located in the extracted tarball in a file called README or INSTALL.
Tarballs often contain the source code of the program, and need to be compiled in order to be used.

	Compiling programs requires some packages that are not installed by default. You can install most of these all at once by installing the build-essential package.

Install .run packages

Sometimes you may need to install software (most often a game) which has been packaged as a .run file. These files contain the software and a small program to install the software.
Follow the procedure below to install software packaged in a .run file:

1. Find the .run file in the File Browser
   
2. Right-click the file and select Properties
   
3. Under the Permissions tab, make sure that Allow executing file as program is checked and press Close
   
4. Double-click the .run file and press Run in Terminal to run the installer
   
5. A Terminal window will open. Follow any instructions on-screen to install the program
   

	Once you have started the installer, it may take a while to display an installation screen. This is normally due to the installer extracting all of the files from the .run file ready for use.
