官网说明: elasticsearch官网建议生产环境需要设置bootstrap.memory_lock: true 官网的解释 是:发生系统swapping的时候ES节点的性能会非常差,也会影响节点的稳定性.所以要不惜一切代价来避免swapping.swapping会导致Java GC的周期延迟从毫秒级恶化到分钟,更严重的是会引起节点响应延迟甚至脱离集群. 所以最好限制住elasticsearch占用的内存情况,可选少用swap 错误内容: 开启bootstrap.memory_lock: t…

问题:在内网测试的时候可以正常访问,但是部署到外网上客户端连接elasticsearch报错:None of the configured nodes are available: [] 原因:默认情况下,ElasticSearch使用0.0.0.0地址,并为http传输开启9200-9300端口,为节点到节点的通信开启9300-9400端口,部署到外网修改修改elasticsearch.yml配置 操作: 修改elasticsearch.yml 将network.host.transport.…
