| 00:01 | Welcome to the Spoken Tutorial on Installation of PostgreSQL. |
| 00:07 | In this tutorial, we will learn to install PostgreSQL on Ubuntu Linux OS and Windows operating system. |
| 00:17 | We will also learn to connect to PostgreSQL database and set password for the database. |
| 00:25 | To record this tutorial, I am using:
Ubuntu Linux 14.04 operating system, Windows 7 operating system and a working internet connection. |
| 00:38 | To follow this tutorial, you should be familiar with either of the mentioned operating system
and have working knowledge of any programming language. |
| 00:49 | PostgreSQL is a relational database management software. |
| 00:54 | It is a powerful and most advanced open source database system. |
| 00:59 | It runs on various platforms such as Linux, Windows and Mac Operating System. |
| 01:07 | First we will see how to install PostgreSQL on Linux. |
| 01:13 | Press CTRL + ALT +T keys simultaneously to open the terminal. |
| 01:20 | In the terminal window, type: sudo apt hyphen get update and press Enter.
Enter the administrative password if prompted. |
| 01:34 | This command will update the Ubuntu's default repositories.
Wait until it finishes all the updates. |
| 01:43 | Press Ctrl L to clear the screen. |
| 01:47 | Next, type: sudo apt hyphen get install postgresql and press Enter. |
| 01:59 | We can see the installation process has begun. |
| 02:03 | Press 'Y' wherever there is a prompt to confirm the configuration. |
| 02:09 | Installation will take sometime to complete, depending upon your internet speed. |
| 02:15 | Now we can see that the installation has been completed successfully.
Press Ctrl + L to clear the screen. |
| 02:25 | By default, a user account called postgres is created during installation.
But there is no password set for this user account. |
| 02:37 | To set the password, type: sudo hyphen u postgres psql postgres and press Enter. |
| 02:49 | Enter your system password if prompted.
Notice that the prompt has changed to postgres equal to hash. |
| 02:59 | At the prompt, type: slash password postgres. |
| 03:05 | Immediately you will be prompted to set a new password for the Postgres user.
I'll enter the password as 'postgres'. |
| 03:15 | You can enter a password of your choice. |
| 03:19 | Enter the same password one more time. |
| 03:23 | Please remember this password for future use. |
| 03:27 | Next, type: select version open bracket close bracket semicolon and press Enter. |
| 03:36 | Do not forget to put the semicolon at the end of each statement. |
| 03:41 | The PostgreSQL version that we have installed now, is displayed on the terminal. |
| 03:47 | This indicates that we have successfully installed PostgreSQL. |
| 03:52 | I have increased the terminal font size for this demo.
Hence the output is seen in a different window. |
| 04:00 | So, I’ll hit the ‘q’ key to exit.
You may not require to do so. |
| 04:07 | Now let us see how to disconnect from the server. |
| 04:11 | Type slash q and press Enter to disconnect from the server. |
| 04:17 | Notice that we are back at the command prompt of the terminal. |
| 04:23 | Every time when you want to work with PostgreSQL, you need to be connected to the server. |
| 04:29 | Psql is an interactive terminal program provided by PostgreSQL. |
| 04:35 | Using psql tool, we can execute SQL statements, manage database objects etc. |
| 04:44 | Another way to connect to a database is using pgAdmin GUI application. |
| 04:51 | We can interact with PostgreSQL database server through this interface. |
| 04:57 | We will be demonstrating all features using pgAdmin in this series. |
| 05:03 | Switch back to terminal.
Let us again connect to the postgreSQL database from the command line. |
| 05:11 | For this, type: sudo psql hyphen capital U postgres hyphen h localhost hyphen capital W
and press Enter to connect to the server. |
| 05:29 | hyphen h is the hostname or IP of the local server. |
| 05:35 | Enter the password for postgres user which you have set after installation. |
| 05:41 | We can see the prompt changes to Postgres.
Press Ctrl + L to clear the screen. |
| 05:49 | Let us verify the PostgreSQL database and whether the server has been started by a simple query. |
| 05:57 | Type: Select current underscore user, now(); |
| 06:05 | We can see the user name and current date as output.
Hit ‘q’ key to exit. |
| 06:13 | During installation, some sample databases are created automatically.
Let us have a look at them. |
| 06:21 | Type: slash list or slash l and press Enter. |
| 06:28 | We can see the below database names that are available in PostgreSQL server, by default.
Hit ‘q’ key to exit. |
| 06:38 | To change a database', type: slash c database name. |
| 06:45 | I will type: slash c postgres.
Then type the postgres password. |
| 06:54 | We can see a message saying You are now connected to database “postgres” as user “postgres”. |
| 07:02 | We can create our own database and tables as per our requirement. |
| 07:08 | All the database commands can be executed from the command line. |
| 07:13 | Type: 'slash q' to disconnect from the server. |
| 07:17 | Now let us see how to install PgAdmin. |
| 07:21 | PgAdmin can be installed by using any one of the following methods on Ubuntu Linux Operating System. |
| 07:30 | Go to Ubuntu Software Centre or Synaptic Package manager, search for PgAdmin and install. |
| 07:39 | For more details, refer to the ‘Linux’ spoken tutorials on our website. |
| 07:45 | Or, in the Terminal, type: sudo apt hyphen get install pgadmin3 and press Enter. |
| 07:56 | I have already installed PgAdmin in my machine.
I'll show how to open PgAdmin. |
| 08:03 | Click Dash Home on the top left corner of the desktop. |
| 08:08 | In the Search box, type: PgAdmin. |
| 08:12 | The PgAdmin icon appears. Click on it. |
| 08:17 | The PgAdmin interface opens. |
| 08:21 | Now let us learn to install PostgreSQL on Windows OS. |
| 08:28 | Open your web browser and go to www.postgresql.org/download
Click on the Windows link. |
| 08:41 | Then, click on the Download the graphical installer link. |
| 08:46 | I have installed postgres version 9.3.x in Linux Operating System. |
| 08:53 | Now I would like to install the same version in Windows also.
You can also install the latest stable version. |
| 09:02 | So, click on the Previous supported versions and look for version 9.3.x |
| 09:09 | Click the link near to the Windows icon. |
| 09:13 | It will open a dialog box to save the file.
Click on the Save File button. |
| 09:20 | It will take sometime to download the file. Wait until it is finished. |
| 09:25 | I have already downloaded it in my machine in the Downloads folder. |
| 09:30 | Go to the Downloads folder and double-click on the downloaded file. It will open a window. |
| 08:37 | Click on the Run button. |
| 08:40 | In the setup window, click on the Next button. |
| 09:44 | Select the components and click on the Next button.
In the Installation directory, click on the Next button. |
| 09:52 | Enter the password for postgres and re-type one more time. Click on the Next button. |
| 10:00 | Installation has started. Wait until it finishes completely. |
| 10:06 | Next, click on the Finish button to complete the installation. |
| 10:11 | Lastly, exit from the wizard. |
| 10:15 | Let us see how to open the PostgreSQL command line on Windows. |
| 10:20 | Click on Start, then All program, then PostgreSQL and psql to open the command line. |
| 10:30 | We can see the postgres prompt. |
| 10:33 | Type: select version() semicolon and press Enter to see the installed version of postgresql. |
| 10:42 | This indicates that we have successfully installed in Windows.
Close the window. |
| 10:49 | Let us open the PgAdmin from Windows. |
| 10:53 | Click on Start, then All program, then PostgreSQL and PgAdmin3 to open the GUI interface. |
| 11:04 | With this, we come to the end of this tutorial. Let us summarize. |
| 11:09 | In this tutorial, we have learnt to install PostgreSQL on Ubuntu Linux and Windows operating systems. |
| 11:18 | As an assignment, connect to the server and list the default available database.
Change to anyone of the available database. |
