対処法

タイムアウトする時間を変更します。

まずは現在のタイムアウトの時間を確認します。

sudo systemctl show elasticsearch | grep ^Timeout
TimeoutStartUSec=1min 30s
TimeoutStopUSec=infinity

sudo systemctl show elasticsearch | grep ^Timeout

TimeoutStartUSec=1min 30s

TimeoutStopUSec=infinity

1分30秒に設定されてます。これを3分に変更します。

ディレクトリを作成します。

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

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

TimeoutStartSec = 180に設定します。

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

<出力結果>
[Service]
TimeoutStartSec = 180

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

out.conf

<出力結果>

[Service]

TimeoutStartSec = 180

daemonを再起動します。

sudo systemctl daemon-reload

1	sudo systemctl daemon-reload

変更されていることを確認します。

sudo systemctl show elasticsearch | grep ^Timeout

<出力結果>
TimeoutStartUSec=3min
TimeoutStopUSec=infinity

sudo systemctl show elasticsearch | grep ^Timeout

<出力結果>

TimeoutStartUSec=3min

TimeoutStopUSec=infinity

再度起動してみます。

sudo systemctl start elasticsearch

1	sudo systemctl start elasticsearch

ステータスを確認してみると正常に起動できたことが確認できました。

sudo systemctl status elasticsearch
