sudo apt-get update
sudo apt-get install mysql-server
|
For PostgreSQL:
1
2
|
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib
|
- Secure the database server: After the installation, it is important to secure the database server to prevent unauthorized access. For MySQL, you can run the following command to secure the installation:
1
|
sudo mysql_secure_installation
|
For PostgreSQL, you can edit the pg_hba.conf
file to set the authentication rules.
- Configure the database server: You can configure the database server to suit your needs by editing the configuration files. For MySQL, the configuration file is located at /etc/mysql/mysql.conf.d/mysqld.cnf, and for PostgreSQL, it is located at /etc/postgresql/<version>/main/postgresql.conf.
- Create databases and users: Once the server is installed and configured, you can create databases and users to access them. For MySQL, you can use the mysql command-line tool to create databases and users. For PostgreSQL, you can use the createdb and createuser commands.
- Test the database server: Finally, you can test the database server by connecting to it and running queries. For MySQL, you can use the mysql command-line tool, and for PostgreSQL, you can use the psql command-line tool.
That's it! You should now have a working database server installed and configured on your Ubuntu machine.
