Install software

Installing YugabyteDB involves completing prerequisites and downloading the YugabyteDB package.

Prerequisites

Before installing YugabyteDB, ensure that you have the following available:

One of the supported operating systems.
Python 3. To check the version, execute the following command:
```
python --version
```
```
Python 3.7.3
```
By default, CentOS 8 does not have an unversioned system-wide python command. To fix this, set python3 as the alternative for python by running sudo alternatives --set python /usr/bin/python3.

Starting from Ubuntu 20.04, python is no longer available. To fix this, run sudo apt install python-is-python3.
wget or curl.

The instructions use the wget command to download files. If you prefer to use curl, you can replace wget with curl -O.

To install wget:
- On CentOS, run yum install wget
- On Ubuntu, run apt install wget
To install curl:
- On CentOS, run yum install curl
- On Ubuntu, run apt install curl
