How to Install Graylog on Alpine Linux Latest

This tutorial will guide you on how to install Graylog on Alpine Linux latest version.

Prerequisites

Before starting the installation process, you should ensure that the following prerequisites are in place:

• A system running Alpine Linux latest version
• Root access to the system
• An active network connection

Step 1: Update the System

The first step in the installation process is to update the system. To do that, execute the following commands:

sudo apk update
sudo apk upgrade

Step 2: Install Java

Graylog requires Java to function correctly. Execute the following command to install Java:

sudo apk add openjdk8-jre

Step 3: Install MongoDB

MongoDB is used as a backend for Graylog. To install MongoDB, execute the following commands:

sudo apk add mongodb
sudo rc-service mongodb start
sudo rc-update add mongodb

Step 4: Install Graylog

Execute the following commands to add the Graylog repository and install Graylog:

sudo sh -c 'echo "http://packages.graylog2.org/repo/packages/graylog-4.0-repository_latest.apk" >> /etc/apk/repositories'
sudo apk update
sudo apk add graylog-server

Now that Graylog is installed, you need to configure it.

Step 5: Configure Graylog

Before starting the Graylog server, you need to configure it. To configure Graylog, you need to follow three steps:

1. Generate Passwords

Graylog requires two passwords - a password for the Graylog admin user and a password for the MongoDB user. Use the following command to generate passwords:

pwgen -N 1 -s 96

Copy the generated password for the Graylog admin user and the MongoDB user to a safe place for future reference.

2. Edit Graylog Configuration

Edit the Graylog configuration file /etc/graylog/server/server.conf using a text editor. Uncomment and edit the following lines:

password_secret = <GENERATED_PASSWORD_1>
root_password_sha2 = <GENERATED_PASSWORD_2>
mongodb_uri = mongodb://127.0.0.1:27017/graylog
mongodb_password = <GENERATED_PASSWORD_2>

Replace <GENERATED_PASSWORD_1> with the password generated for the Graylog admin user and <GENERATED_PASSWORD_2> with the password generated for the MongoDB user.

3. Start Graylog Server

Execute the following command to start the Graylog server:

sudo graylog-server start
