How to install postgresql on windows subsystem for linux (WSL) and link it to DataGrip

Assume that your user name are:

• root on WSL
• jackj on Windows

1 Install WSL

Please refer to Windows 10 Installation Guide

2 Install postgresql

sudo apk-get install postgresql     # install postgresql

3 Add user

To use postgresql, we should add your user name to postgresql

sudo service postgresql start     # start postgresql service, note you cannot use pg_clt -start
sudo su postgres    # login as user "postgres" which is automatically created by postgresql
psql postgres          # open database "postgres" which is the default database created by postgresql

Now we should see postgres=#

create user root;      # add your user name to postgresql
alter user root with superuser;     # alter your user's role to superuser
\q    # quit 

Close WSL window and restart.

4 Transfer file

In order to transfer files from Windows to WSL, we need to create a symbolic link.

ln -s "/mnt/c/Users/jackj/Documents/WSL" /root/WSL

After that, My Documents/WSL on Windows to /root/WSL on WSL are linked together.

5 Use postgresql

You may put your file schema.sql on My Documents/WSL

sudo service postgresql start    # start server
cd ~/WSL    # enter your working directory
createdb a2     # create database
psql a2    # open database
\i shema.sql   # insert schema.sql and do anything you like just as same as what we did in lab

6 Link DataGrip
