Install postgresql server ubuntu11/18/2023 Remember to replace with your email address and set a strong secure password as well: $ sudo /usr/pgadmin4/bin/setup-web.sh This script will configure Apache2 to serve the pgAdmin4 web application which involves enabling the WSGI module and configuring the pgAdmin application to mount at pgadmin4 on the webserver so you can access it at: It also restarts the Apache2 service to apply the recent changes. You will be prompted to create a pgAdmin4 login email and password as shown in the screenshot below. Once the installation is complete, run the web setup script which ships with the pgdmin4 binary package, to configure the system to run in web mode. The above command will install numerous required packages including Apache2 webserver to serve the pgadmin4-web application in web mode. Then install pgAdmin4, $sudo apt install pgadmin4 $ sudo sh -c 'echo "deb $(lsb_release -cs) pgadmin4 main" > /etc/apt//pgadmin4.list & apt update' Add the public key for the repository and create the repository configuration file. We need to install it from the pgAdmin4 APT repository. PgAdmin4 is not available in the Ubuntu repositories. So, ensure that the entries below have md5 as the under method: host all all 127.0.0.1/32 md5Īfter making changes in the Client Authentication configuration file, you will need to restart the PostgreSQL service. Md5 is the most secure and recommended because it requires the client to supply a double-MD5-hashed password for authentication. PostgreSQL uses many types of client authentication methods including peer, ident, password, and md5 (read the PostgreSQL 12 documentation for a detailed explanation of each method). $ sudo vim /etc/postgresql/12/main/pg_hba.conf Open this file using your favorite text editor as shown. PostgreSQL uses client authentication to decide which user accounts can connect to which databases from which hosts and this is controlled by settings in the client authentication configuration file, which on Ubuntu is located at /etc/postgresql/12/main/pg_hba.conf. Postgres=# GRANT ALL PRIVILEGES ON DATABASE tecmintdb to tecmint Ĭreate a Database in PostgreSQL Configuring PostgreSQL Client Authentication postgres=# CREATE USER tecmint WITH PASSWORD CREATE DATABASE tecmintdb Now create a new database and a user using the following commands. First, switch to the postgres system user account and run the psql command as follows: $ sudo su - postgres To create a new database in PostgreSQL, you need to access the PostgreSQL database shell (psql) program. PostgreSQL Accepting Client Connections Creating Database in PostgreSQL createdb database_nameįor this, we will create a new Linux system user by using adduser.įor simplicity purpose, we will be using the same name as which we created the postgres role with, adam.After PostgreSQL installed, you can confirm that the PostgreSQL service is active, running and is enabled under systemd using the following systemctl commands: $ sudo systemctl is-active postgresqlĪlso, confirm that the Postgresql server is ready to accept connections from clients as follows: $ sudo pg_isready Run the below command as a postgres user account. Shall the new role be a superuser? (y/n) yĬreating a database is as simple as it gets. Now let us see how we can create additional users that can interact with the Databases.įor this, you have to be a postgres user and then run the command as shown below, createuser -interactive To exit the postgres shell, use the below command, \q You can access a PostgreSQL prompt using the psql utility psql We'll switch to the Postgres user account for the next steps, to switch to the Postgres account, use the following command, sudo -i -u postgres Postgresql-client-14 postgresql-client-common postgresql-common sysstat PostgreSQL Roles and Databases Libsensors-config libsensors5 libtypes-serialiser-perl postgresql-14 Libcommon-sense-perl libjson-perl libjson-xs-perl libllvm14 libpq5 The following additional packages will be installed: Libmariadb3 libmysqlclient21 libndctl6 libpmem1 libsnappy1v5 liburing2 Galera-4 libconfig-inifiles-perl libdaxctl1 libdbd-mysql-perl libdbi-perl The following packages were automatically installed and are no longer required: Output: apt install postgresql postgresql-contrib Install PostgreSQL on Ubuntu by using the following command apt updateĪpt install postgresql postgresql-contrib PostgreSQL is a powerful, open-source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
