当前elasticsearch版本8.11.4，报错内容如下：
|
1 2 3 |
[ERROR][o.e.b.Elasticsearch ] [ceph1] node validation exception [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch. For more information see [https://www.elastic.co/guide/en/elasticsearch/reference/8.11/bootstrap-checks.html] bootstrap check failure [1] of [1]: memory locking requested for elasticsearch process but memory is not locked; for more information see [https://www.elastic.co/guide/en/elasticsearch/reference/8.11/_memory_lock_check.html] |
这是因为在elasticsearch配置文件中开启了bootstrap.memory_lock: true参数。
解决办法：
1、如果你是rpm等相关方式安装的，可以通过以下方式解决
|
1 |
systemctl edit elasticsearch |
|
1 2 |
[Service] LimitMEMLOCK=infinity |
按F2，再按y，再回车
2、如果你是通过.tar、.zip包安装的，可以通过以下方式解决
|
1 |
vi /etc/security/limits.conf |
|
1 2 |
elasticsearch soft memlock unlimited elasticsearch hard memlock unlimited |
