ERROR: $2$ bootstrap checks failed.You must address the points described in the following $2$ lines before starting Elasticsearch.

bootstrap checks failed $1$ of $2$ : memory locking requested for elasticsearch process but memory is not locked

bootstrap checks failed $1$ of $2$ : max virtual memory areas vm.max_map_count $65530$ is too low, increase to at least $262144$

ERROR: Elasticsearch did not exit normally - check the logs at /a/es/logs/my-cluster.log

系统：centos7.6 （vm虚拟机）

软件：java-1.8、elasticsearch-5.6.16-1.noarch

错误信息：

$2019-11-21T00:29:51,557$ $ERROR$ $o.e.b.Bootstrap$ $elk-1$ node validation exception

$1$ bootstrap checks failed

$1$ : memory locking requested for elasticsearch process but memory is not locked

解决方法一(关闭bootstrap.memory_lock:，会影响性能）：

vim /etc/elasticsearch/elasticsearch.yml // 设置成false就正常运行了。

bootstrap.memory_lock: false

解决方法二（开启bootstrap.memory_lock:）：

bootstrap.memory_lock: true

bash 复制代码

vim /etc/security/limits.conf

bash 复制代码

* soft nofile 65536

* hard nofile 65536

* soft nproc 32000

* hard nproc 32000

* hard memlock unlimited

* soft memlock unlimited

bash 复制代码

DefaultLimitNOFILE=65536

DefaultLimitNPROC=32000

DefaultLimitMEMLOCK=infinity

改好后重启下系统。再启动elasticsearch就没报错了。

bash 复制代码

vim /etc/sysctl.conf

保存文件并执行以下命令使修改生效：

bash 复制代码

   sysctl -p
