Prerequisites

Before we begin, you will need to make sure that you have the following prerequisites:

• A machine running EndeavourOS latest
• A root or sudo access to the machine
• An internet connection

Step 1: Download OpenSearch

The first step in installing OpenSearch is to download it from the official website. To download the OpenSearch package, follow the next instructions.

2. Scroll down to the "Recent Releases" section and find the latest version of OpenSearch.
3. Click on the "Download" button next to the version you want to install.
4. Choose the package that corresponds to your operating system.

Step 2: Installing Java

OpenSearch requires Java to run. If you don't have Java installed on your machine, you can install it using the following command:

sudo pacman -S jdk-openjdk

Step 3: Installing OpenSearch

Once you have downloaded the OpenSearch package and installed Java, follow the next steps to install OpenSearch on EndeavourOS latest.

1. Open the terminal and navigate to the directory where you downloaded the OpenSearch package.
2. Extract the package using the following command:

tar zxvf opensearch-{version}-linux-x86_64.tar.gz

Note: Replace {version} with the version of OpenSearch you downloaded.

3. Move the extracted package to the /opt directory using the following command:

sudo mv opensearch-{version} /opt/opensearch

Note: Replace {version} with the version of OpenSearch you downloaded.

4. Change the ownership of the /opt/opensearch directory to the current user using the following command:

sudo chown -R $USER:$USER /opt/opensearch

5. Create a symbolic link for the opensearch.sh startup script using the following command:

sudo ln -s /opt/opensearch/bin/opensearch.sh /usr/bin/opensearch

Step 4: Starting OpenSearch

You can start the OpenSearch service by running the following command:

sudo systemctl start opensearch

To make sure that the OpenSearch service is running, run the following command:

sudo systemctl status opensearch

If the service is running correctly, you will see the following output:

● opensearch.service - OpenSearch
     Loaded: loaded (/etc/systemd/system/opensearch.service; disabled; vendor preset: disabled)
     Active: active (running) since Wed 2021-11-10 17:12:06 UTC; 5s ago

Step 5: Configuring OpenSearch

By default, OpenSearch listens on localhost (127.0.0.1) port 9200. If you want to access OpenSearch from a remote machine, you will need to configure it to listen on a public IP address.

To configure OpenSearch, you need to edit the /opt/opensearch/config/opensearch.yml file using your favorite text editor:

sudo nano /opt/opensearch/config/opensearch.yml

In the file, change the network.host value to the IP address of your machine. For example:

network.host: 192.168.1.10

Note: Replace 192.168.1.10 with your machine's IP address.

After making the changes, save and close the file.
