當啓動 ES 時報錯如下:
ERROR: [1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
{"type": "server", "timestamp": "2019-12-01T11:34:18,422+0000", "level": "INFO", "component": "o.e.n.Node", "cluster.name": "geektime", "node.name": "es7_02", "message": "stopping ..." }
解決方案:
編輯 /etc/security/limits.conf,追加以下內容;
* soft nofile 65536
* hard nofile 65536
編輯 /etc/sysctl.conf,追加以下內容:
vm.max_map_count=655360
保存後,執行:
sysctl -p
重新啓動,成功。
