Ubuntu Elasticsearch Kurulumu

# Elasticsearch kullanıcısı oluşturulur ve yetkilendirilir
sudo adduser elasticsearch
sudo usermod -aG sudo elasticsearch

# Kullanıcıya geçilerek işlemlere devam edilir
sudo su - elasticsearch

# Aşağıdaki araçların tüm sunucular üzerinde kurulu olması tavsiye edilmektedir
sudo apt update
sudo apt install -y curl wget net-tools gnupg2 software-properties-common apt-transport-https ca-certificates

# Güvenlik duvarı kapatılır
sudo systemctl stop ufw
sudo systemctl disable ufw

# Swap kapatılır ve yeniden başlamasının önlenmesi için /etc/fstab dosyası içindeki swap satırı silinir
sudo swapoff -a
sudo vi /etc/fstab
# Daha sonra vi dosyasını kapatılır (:wq)
