Install PostgreSQL 9.4 And phpPgAdmin On Ubuntu 15.10


PostgreSQL is a powerful, open-source object-relational database system. It runs under all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS, Solaris, Tru64), and Windows OS.

Here is what Mark Shuttleworth, the founder of Ubuntu, says about PostgreSQL.

Postgres is a truly awesome database. When we started working on Launchpad I wasn’t sure if it would be up to the job. I was so wrong. It’s been robust, fast, and professional in every regard.

— Mark Shuttleworth.

In this handy tutorial, let us see how to install PostgreSQL 9.4 on Ubuntu 15.10 server.

Install PostgreSQL

PostgreSQL is available in the default repositories. So enter the following command from the Terminal to install it.

sudo apt-get install postgresql postgresql-contrib

If you’re looking for other versions, add the PostgreSQL repository, and install it as shown below.

The PostgreSQL apt repository supports LTS versions of Ubuntu (10.04, 12.04 and 14.04) on amd64 and i386 architectures as well as select non-LTS versions(14.10). While not fully supported, the packages often work on other non-LTS versions as well, by using the closest LTS version available.

On Ubuntu 14.10 systems:

Create the file /etc/apt/sources.list.d/pgdg.list;

sudo vi /etc/apt/sources.list.d/pgdg.list

Add a line for the repository:

deb utopic-pgdg main

Note: The above repository will only work on Ubuntu 14.10. It is not updated yet to Ubuntu 15.04 and 15.10.

On Ubuntu 14.04, add the following line:

deb trusty-pgdg main

On Ubuntu 12.04, add the following line:

deb precise-pgdg main

Import the repository signing key:

wget --quiet -O -
sudo apt-key add -

Update the package lists:

sudo apt-get update

Then install the required version.

sudo apt-get install postgresql-9.4

Accessing PostgreSQL command prompt

The default database name and database user are “postgres”. Switch to postgres user to perform postgresql related operations:

sudo -u postgres psql postgres

Sample Output:

psql (9.4.5)
Type "help" for help.


To exit from posgresql prompt, type \q in the psql prompt return back to the Terminal.

Set “postgres” user password

Login to postgresql prompt,

sudo -u postgres psql postgres

.. and set postgres password with following command:

postgres=# \password postgres 
Enter new password: 
Enter it again: 
postgres=# \q

To install PostgreSQL Adminpack, enter the command in postgresql prompt:

sudo -u postgres psql postgres
postgres=# CREATE EXTENSION adminpack;

Type \q in the psql prompt to exit from posgresql prompt, and return back to the Terminal.

Create New User and Database

For example, let us create a new user called “senthil” with password “ubuntu”, and database called “mydb”.

sudo -u postgres createuser -D -A -P senthil
sudo -u postgres createdb -O senthil mydb

Delete Users and Databases

To delete the database, switch to postgres user:

sudo -u postgres psql postgres

Enter command:

$ drop database <database-name>

To delete a user, enter the following command:

$ drop user <user-name>

Configure PostgreSQL-MD5 Authentication

MD5 authentication requires the client to supply an MD5-encrypted password for authentication. To do that, edit /etc/postgresql/9.4/main/pg_hba.conf file:

sudo vi /etc/postgresql/9.4/main/pg_hba.conf

Add or Modify the lines as shown below

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all               md5
host    all             all             md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

Here, is my local network IP address. Replace this value with your own address.

Restart postgresql service to apply the changes:

sudo systemctl restart postgresql


sudo service postgresql restart

Configure PostgreSQL-Configure TCP/IP

By default, TCP/IP connection is disabled, so that the users from another computers can’t access postgresql. To allow to connect users from another computers, Edit file /etc/postgresql/9.4/main/postgresql.conf:

sudo vi /etc/postgresql/9.4/main/postgresql.conf

Find the lines:

#listen_addresses = 'localhost'
#port = 5432

Uncomment both lines, and set the IP address of your postgresql server or set ‘*’ to listen from all clients as shown below. You should be careful to make postgreSQL to be accessible from all remote clients.

listen_addresses = '*'
port = 5432

Restart postgresql service to save changes:

sudo systemctl restart postgresql


sudo service postgresql restart

Manage PostgreSQL with phpPgAdmin

phpPgAdmin is a web-based administration utility written in PHP for managing PosgreSQL.

phpPgAdmin is available in default repositories. So, Install phpPgAdmin using command:

sudo apt-get install phppgadmin

By default, you can access phppgadmin using http://localhost/phppgadmin from your local system’s web browser.

To access remote systems, do the following.

On Ubuntu 15.10 systems:

Edit file /etc/apache2/conf-available/phppgadmin.conf,

sudo vi /etc/apache2/conf-available/phppgadmin.conf

Find the line Require local and comment it by adding a # in front of the line.

#Require local

And add the following line:

allow from all

Save and exit the file.

Then, restart apache service.

sudo systemctl restart apache2

On Ubuntu 14.10 and previous versions:

Edit file /etc/apache2/conf.d/phppgadmin:

sudo nano /etc/apache2/conf.d/phppgadmin

Comment the following line:

#allow from ::1/128

Uncomment the following line to make phppgadmin from all systems.

allow from all

Edit /etc/apache2/apache2.conf:

sudo vi /etc/apache2/apache2.conf

Add the following line:

Include /etc/apache2/conf.d/phppgadmin

Then, restart apache service.

sudo service apache2 restart

Configure phpPgAdmin

Edit file /etc/phppgadmin/, and do the following changes. Most of these options are self-explanatory. Read them carefully to know why do you change these values.

sudo nano /etc/phppgadmin/

Find the following line:

$conf['servers'][0]['host'] = '';

Change it as shown below:

$conf['servers'][0]['host'] = 'localhost';

And find the line:

$conf['extra_login_security'] = true;

Change the value to false.

$conf['extra_login_security'] = false;

Find the line:

$conf['owned_only'] = false;

Set the value as true.

$conf['owned_only'] = true;

Save and close the file. Restart postgresql service and Apache services.

sudo systemctl restart postgresql
sudo systemctl restart apache2


sudo service postgresql restart
sudo service apache2 restart

Now open your browser and navigate to http://ip-address/phppgadmin. You will see the following screen.

phpPgAdmin – Google Chrome_001

Login with users that you’ve created earlier. I already have created a user called “senthil” with password “ubuntu” before, so I log in with user “senthil”.

phpPgAdmin – Google Chrome_002

Now, you will be able to access the phppgadmin dashboard.

phpPgAdmin – Google Chrome_003

Log in with postgres user:

phpPgAdmin – Google Chrome_004

That’s it. Now you’ll able to create, delete and alter databases graphically using phppgadmin.

    Thanks for the tutorial. Have you ever configure LDAP and/or TLS on Postgresql?
