You have to notice that Graylog has four main components:
- Graylog Server nodes: Serves as a worker that receives and processes messages, and communicates with all other non-server components.
- Elasticsearch nodes: a server that stores all of the logs & messages.
- MongoDB: For storing metadata
- Web Interface: the GUI
You have to install all the prerequisites first:
Installing Java then update:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
Install MongoDB and create the source list:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
after that update and install the latest available stable version:
sudo apt-get update
sudo apt-get install mongodb-org
Install Graylog Server:
cd ~
wget https://packages.graylog2.org/repo/packages/graylog-1.3-repository-ubuntu14.04_latest.deb
sudo dpkg -i graylog-1.3-repository-ubuntu14.04_latest.deb
sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get install graylog-server
sudo apt-get install pwgen
SECRET=$(pwgen -s 96 1)
sudo -E sed -i -e 's/password_secret =.*/password_secret = '$SECRET'/' /etc/graylog/server/server.conf
PASSWORD=$(echo -n password | shasum -a 256 | awk '{print $1}')
sudo -E sed -i -e 's/root_password_sha2 =.*/root_password_sha2 = '$PASSWORD'/' /etc/graylog/server/server.conf
Until this step the admin password is there installed, after that you need to configure graylog to your needs, and you can find the config file here :
sudo vi /etc/graylog/server/server.conf
Good luck,
