剛剛安裝的elasticsearch啟動報錯
查看日志/var/log/message
Sep 27 11:13:17 local-nginx elasticsearch: Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: org.elasticsearch.cli.UserException: unable to create temporary keystore at [/etc/elasticsearch/elasticsearch.keystore.tmp], please check filesystem permissions
原因：第一次啟動需要創建keystore文件，但是配置文件路徑/etc/elasticsearch/ 沒有權限
設置權限
chown -R elasticsearch:elasticsearch /etc/elasticsearch/
再重啟即可
systemctl restart elasticsearch
PS：之前安裝elasticsearch無需手動設置該權限
