create and setup user password upon creation
createuser kodekloud_roy -–pwprompt
this configuration is also correct for pg_hba.conf
local kodekloud_db9 kodekloud_roy md5

hi all,
what could be the default password for this file?
I have not set any password after installing postgres.
please advise.
In Linux by default, a user named postgres is created once PostgreSQL is installed. Default password for this is empty.
You can change the user’s password with the following command:
sudo passwd postgres
First come out from that bash shell to default user then do changes. You don’t need password for that even need though you knew the default user password like tony, steve etc. To make changes in database then login again by sudo su postgres whatever you did.
hi Tej
I was able to reset the password, after that,while I was trying to update the conf file.
I am getting this message. any suggestions.
this is the password I set for postgres - Password@123
also, executing this command, I am seeing this result, is this correct, because one of the user has attached the results with roles. In my case it was coming empty.
I dont think you need to do a sudo to modify pg_hba.conf with the postgres user, postgres is not a OS admin, just the DB admin, bu default it should have permissions for this file
su - postgres
vi var/lib/pgsql/data/pg_hba.conf
that’s why i am saying postgres is not a sudo user and don’t have permission to change the files.
Do one thing if you are updating database then change user into postgres. If you have to change configuration file of the system then switch into DB server sudo user.
That’s the good steps i guess.
postgres -----> CRUD database(CREATE, REPLACE, UPDATE, DELETE)
sudo user -----> configuration files of system(database)
task 4 :-- In the configuration file of psql. Configure it according to task that allow all local clients or can say that local user to connect to the kodekloud_db4 database with database user kodekloud_cap user with md5 password as already there password column.
pg_hba.conf file has section of “local” where is encryption set to peer but we need to change into md5.
Don’t change other section peer to md5 otherwise task will be failed. Only to local.
task 5 :-- Try with sudo user or root user to login with that credentials(database user and database password).
I don’t know exactly but something like
$root ># psql -u kodekloud_cap -d kodekloud_db4 -p
u stands for user.
p stands for password
d stands for database
not sure but search it on internet to confirm.
Your /var/lib/pgsql/12/data/pg_hba.conf not looks like actual file of psql. Have you changed something?

Would you please check my “Install and Configure PostgresSQL” task. I thought I did it correctly and clicked “Finish” I however got status failed. And I don’t know why. I attached you some screenshots.
This is the reason shown on the failed status
“PostgreSQL is not configured correctly, either user ‘kodekloud_pop’ and database ‘kodekloud_db1’ does not exist or user ‘kodekloud_pop’ does not has appropriate permissions on database ‘kodekloud_db1’ on DB Server”
Kind regards

Have you initialize the PostgreSQL DB using,
sudo postgresql-setup initdb
If not then you need to first initialize the DB.
Secondly, you need to login Postgresql using
sudo -u postgres psql
After login you need to create the user and database and grant the permission.
Also, you need to just change only one configuration line from /var/lib/pgsql/data/pg_hba.conf
local all all peer to local all all md5
After that you need to restart the postgresql service.
@AkshayT thanks for replying. Yes, I did initialize the database. And did the necessary configuration on the pg_hba.conf file and restarted the service.
Dear @mmumshad @Inderpreet @kodekloud-support3
I am eagerly waiting for your reply. Would you please check my PostgreSQL Task?
kind regards.
You did typo at all. Database name is kodekloud_db1 not kodeKloud_db1 
Thanks @Tej-Singh-Rana for replying. Is that the case and does it really mater? Is name of a database case sensitive? I don’t know that can be, but it will be very pity if I miss it because of it.
i am getting below error while connecting to postgresql.
psql -d kodekloud_db1 -U kodekloud_top -W
Password for user kodekloud_top:
psql: FATAL: Peer authentication failed for user “kodekloud_top”
