1. sudo systemctl show elasticsearch | grep ^Timeout
TimeoutStartUSec=1min 15s
TimeoutStopUSec=0

2. sudo mkdir /etc/systemd/system/elasticsearch.service.d

3. echo -e "[Service]\nTimeoutStartSec=180" | sudo tee /etc/systemd/system/elasticsearch.service.d/startup-timeout.conf
[Service]
TimeoutStartSec=180

4. sudo systemctl daemon-reload
5. sudo systemctl show elasticsearch | grep ^Timeout
TimeoutStartUSec=3min
TimeoutStopUSec=0

6. sudo service elasticsearch start
