HOW TO INSTALL MINIO ON ROCKY LINUX 8

Prerequisites

An Rocky Linux system.
A user with root or sudo privileges. This user will be used for installing new packages and make changes system-wide.

Downloading MinIO on Rocky Linux

Use the following command to download a standalone MinIO server on Linux hosts running 64-bit Intel/AMD architectures. Replace /data with the path to the drive or directory in which you want MinIO to store data.

dnf -y install wget
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
mkdir /data
mv minio /usr/local/bin

Create default configuration

This file serves as input to MinIO systemd service. Use this file to add MINIO_VOLUMES with the correct paths, MINIO_OPTS to add MinIO server options like certs-dir, address. MinIO credentials can be MINIO_ROOT_USER and MINIO_ROOT_PASSWORD in this file as well.
Run the command bellow to create the file with minio parameters.

cat <<EOT >> /etc/default/minio
# Volume to be used for MinIO server.
MINIO_VOLUMES="/data"
# Use if you want to run MinIO on a custom port.
MINIO_OPTS="--address :9199"
# Root user for the server.
MINIO_ROOT_USER=spf-user
# Root secret for the server.
MINIO_ROOT_PASSWORD=spf-Password
# setting access key to access the interface web
MINIO_ACCESS_KEY="minio"
# setting secret key. Avoid using the value default from this tutorial.
MINIO_SECRET_KEY="miniostorage"

HOW TO INSTALL ROCKY LINUX 8

HOW TO INSTALL MONGODB ON ROCKY LINUX

Prerequisites

A fresh server running Rocky Linux 8 with a minimum of 10 GB of free disk space
A non-root user with sudo privileges configured on the server

Update the System

sudo dnf update -y

Installing MongoDB

The MongoDB package is not included in the default repositories for Rocky Linux 8 because it is not considered part of the "base" system. Thus, you need to add the repository containing the package before installing MongoDB.

MongoDB comes in two editions the community edition and the enterprise edition. The community edition is free while the enterprise edition offers additional features. This guide is for the community edition.

Run the following command to add the MongoDB Repository on your system.

cat > /etc/yum.repos.d/mongodb.repo << 'EOL'
[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc
EOL

Once the repository is enabled, run the following command to install the mongoDB community edition.

dnf update
dnf install -y mongodb-org

Once the installation is complete, verify the version installed as follows.

mongod --version

The MongoDB service doesn't start automatically after installation. You can verify this by running the command as follows.

systemctl status mongod

The output should be similar to that below:

Since the service has not started, start it manually by running the following command.

systemctl start mongod

To enable MongoDB to automatically start on boot time, run the following command.

systemctl enable mongod

At this point, MongoDB has been installed and configured on the server. Verify the status of MongoDB service as follows.

systemctl status mongod

HOW TO INSTALL POSTGRESQL ON ROCKY LINUX

Prerequisites

An Rocky Linux system.
A user with root or sudo privileges. This user will be used for installing new packages and make changes system-wide.

Installing PostgreSQL on Rocky Linux

List out the available streams for the postgresql module using the dnf command:

dnf module list postgresql

Output

[root@node02-postgresql ~]# dnf module list postgresql

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

You can see in this output that there are four versions of PostgreSQL available from the AppStream repository: 9.6, 10, 12, and 13. The stream that provides Postgres version 10 is the default, as indicated by the [d] following it. To install that version, you could just run sudo dnf install postgresql-server and move on to the next step. However, even though version 10 is still maintained, this tutorial will install Postgres version 16.

To install PostgreSQL version 16, you must enable that version’s module stream. When you enable a module stream, you override the default stream and make all of the packages related to the enabled stream available on the system. Note that only one stream of any given module can be enabled on a system at the same time.

To enable the module stream for Postgres version 16, run the following command:

sudo dnf module enable postgresql:16

When prompted, press y and then ENTER to confirm that you want to enable the stream:

Output

[root@node02-postgresql ~]# dnf module enable postgresql:16

Transaction Summary
=======================================================================================================================================================

Is this ok [y/N]: y
Complete!

Install the latest version of PostgreSQL from the repository using the dnf command below.

dnf install postgresql-server.x86_64

PostgreSQL Database Initialization

Next, after the PostgreSQL installation is complete, you must initialize the PostgreSQL configuration and then start and enable the PostgreSQL service.

1. Execute the following command to initialize the PostgreSQL database configuration.

postgresql-setup --initdb --unit postgresql

2. After that, start and enable the PostgreSQL service using the command below.

sudo systemctl enable postgresql
sudo systemctl start postgresql

Now the PostgreSQL service is active and running, and it will run automatically on every boot.

3. Now execute the command below to verify the PostgreSQL service.

systemctl status postgresql

If your PostgreSQL service is running, you will see the green output such as "active(running)" as below. Otherwise, you will see the red output such as "failed" following by the error message logs.

Securing PostgreSQL Deployment

During the installation, PostgreSQL will create a new system user and database user name as "postgres". And for this stage, you will be setting up a new password for the "postgres" user, both for the system user and database user.

1. Change the password for default system user "postgres" using the following command.

passwd postgres

Now type the new password for the system user "postgres".

2. Next, to change the password for the "postgres" database user, you must log in to the PostgreSQL shell.

First, log in as a system user "postgres" using the following command.

su - postgres

psql

Execute the following query to create a new password for the default "postgres" database user.

ALTER USER postgres WITH PASSWORD 'strongpostgrespassword';

Change the string 'strongpostgrespassword' to your own password. Now type exit and press "Ctrl+d" to exit and log out from the 'postgres' user shell.

Change Authentication Method

By default, local PostgreSQL users will connect to the PostgreSQL shell using the 'peer' method. The peer authentication method will work only for local connections. In the development environment, you can use this type of authentication, but for production, consider using the password-based authentication method.

For this stage, you will learn how to change the default peer authentication method to password authentication using 'md5'.

1. First, log in to the PostgreSQL shell using the following command.

sudo -u postgres psql

Now execute the following query to check the location of the PostgreSQL configuration 'pg_hba.conf'.

SHOW hba_file;
SHOW password_encryption;

You will see the output as below.

You will notice the PostgreSQL configuration "pg_hba.conf" are located at the '/var/lib/pgsql/data' directory, and the default password encryption for PostgreSQL on RHEL based operating system is 'md5'.

Now type '\q' to exit and quit the PostgreSQL shell.

2. Next, change the working directory to '/var/lib/pgsql/data' and edit the configuration 'pg_hba.conf' using nano editor.

cd /var/lib/pgsql/data/
vi pg_hba.conf

At the bottom of the line, change the local authentication method to 'md5' as below.

Now press 'ESC', type ':wq', and press "Enter" to save and exit.

Using this configuration, you will be prompted for the password to log in to the PostgreSQL shell.

3. Next, apply the new configuration by restarting the PostgreSQL service using the following command.

systemctl restart postgresql

Now every time you want to access the PostgreSQL shell, you must type the password for authentication.

4. To make sure of the password authentication configuration, log in to the PostgreSQL shell using the following command.

su - postgres
psql

Now you will be asked for a password for the default user 'postgres'.

Type the password for the 'postgres' database user and press 'Enter'. If your password is correct, you will see the PostgreSQL shell as follows. Otherwise, you will see the 'FATAL' error because the password is incorrect.

Additionally, you can use the one-line command to log in to the PostgreSQL shell as below.

# Log in as default "postgres" user
sudo -u postgres psql

# Log in as another user
sudo -u postgres psql -U username

Creating New User and Database for your Application

At this stage, you will learn how to create a new user and database on PostgreSQL.

1. Log in to the PostgreSQL shell by executing the command below.

sudo -u postgres psql

Now type the password for PostgreSQL user 'postgres'.

2. Run the PostgreSQL query below to create a new user 'johndoe' with the password 'johndoestrongpassword' and give the user privileges for creating a new database and role.

CREATE USER spf WITH 
CREATEDB
CREATEROLE
PASSWORD 'spfstrongpassword';

After that, verify the new user using the following query.

\du

Now you will see the new user 'spf' with the list of roles 'Create role' and 'Create DB' as below.

3. Next, to create a new user database on PostgreSQL, run the following query.

CREATE DATABASE spf OWNER spf;

Now verify the new database using the following query.

\l

And you will see the new database 'spf' with the owner 'spf' as the screenshot below.
