I install elasticsearch 7.3 using this command
```
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.3.2-amd64.deb
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.3.2-amd64.deb.sha512
shasum -a 512 -c elasticsearch-7.3.2-amd64.deb.sha512
sudo dpkg -i elasticsearch-7.3.2-amd64.deb
```
my server is ubuntu 18.04
I am trying to setup 3 nodes elasticsearch with some security so I am trying to setup
`Encrypting communications in Elasticsearch`
although when I follow the link I am getting error to the very first command
`bin/elasticsearch-certutil ca`
`-bash: bin/elasticsearch-certutil: No such file or directory`
also I am in my root directory.
Thanks.

The installation guide gives you information on how to install and at the end where are located the binaries. See [https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html)

Yes I followed that link only in order to install elasticsearch, but I didn't go through these commands:
`wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -`
`sudo apt-get install apt-transport-https`
`echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list`
now what should I do ? should I reinstall the whole elasticsearch again by uninstalling them ?
