- Install PostgresSQL server on Ubuntu and remote access with Python
Step 1. Install PostgresSQL Server
- Check which version of PostgreSQL to install on Ubuntu
- PostgreSQL Package Setting
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list. d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
- Install PostgreSQL on Ubuntu
sudo apt-get -y install postgresql
sudo apt install postgresql postgresql-contrib
- Run PostgresSQL service
sudo service postgresql start
sudo service postgresql status
Step 2. Set PostgresSQL Admin Account
- Connect PostgresSQL Server and
- Confirm the current connection and user information
- Set Passwords of PostgresSQL Admin Account
- 'postgres' is default admin account of PostgresSQL
ALTER USER postgres WITH PASSWORD '{passwords}';
- Show PostgresSQL Accounts
Step 3. Create PostgresSQL Database
- Create PostgresSQL Database
CREATE DATABASE {db_name} OWNER postgres;
- Show PostgresSQL Database
- Disconnect PostgresSQL Server
Step 4. Allow Remote Access
- Move to path of PostgresSQL configs file
cd /etc/postgresql/{version_of_PostgresSQL}/main
- Edit 'postgresql.conf' file
- Set 'listen_addresses' as '0.0.0.0' for listening to all IPs
- Set 'port' to the port you want to connect to
sudo nano postgresql.conf
- Restart PostgresSQL service
- For applying modified configs file
sudo service postgresql restart
- Edit 'pg_hba.conf' file
- Add line as follow for allowing to connect all IPs
- Restart PostgresSQL service
- For applying modified configs file
sudo service postgresql restart
Step 5. Test Remote Access
- Test remote access to PostgresSQL server and running query
- Custom python PostgresSQL server class
- Connect PostgreSQL server, Create table, Insert data, Select data etc.
python db_test --host '{server_ip}' --port {port} --db_name '{db_name}' --user 'postgres' --password '{password}' --table_name '{table_name}'
- Confirm data in created database
sudo -i -u postgres
psql -d {db_name} -U postgres -W
SELECT * FROM {table_name};
