As we know, we should install elasticsearch 7 for Magento 2.4.3. If we do not have installed asticsearch 7, usually we should install java on our web hosting first, then we can install asticsearch 7. Today I share another method to install asticsearch 7 without java-1.8.0-openjdk. I have tested the method under Nginx, php7.4, ubuntu18.0.4 and ubuntu 20.0.4 for https://www.prescriptionglassesonline.net/
First, install the required dependencies with the following command:
$ sudo apt install apt-transport-https ca-certificates gnupg2 -y
Then, we need to import the GPG key with the following command:
$ wget -O – http://packages.elasticsearch.org/GPG-KEY-elasticsearch | sudo apt-key add –
or
$ wget -qO – https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add –
At last, we can run the following command to add the Elasticsearch repository:
sudo sh -c ‘echo “deb https://artifacts.elastic.co/packages/7.x/apt stable main” > /etc/apt/sources.list.d/elastic-7.x.list’
We need to update the repository cache to be able to install the Elasticsearch with the following command:
$ sudo apt update -y
$ sudo apt install elasticsearch -y
That’s it, elasticsearch has been successfully installed. We can enable the service and start it by running this command below:
$ sudo systemctl –now enable elasticsearch
To verify whether Elasticsearch is running or not we can run the following command:
$ curl -X GET “localhost:9200”
You will be presented with a message like this.
