Elasticsearch 6.3 绑定(bind)或发布到非环回地址，强制执行 Bootstrap 检查

Question

为了在 Docker (--net=host) 中设置新的 ES 6.3 集群，我苦苦挣扎了好几天。错误如下:

[2018-06-20T16:31:45,766][INFO ][o.e.t.TransportService   ] [rpi-1] publish_address {192.168.0.101:9300}, bound_addresses {192.168.0.101:9300}
[2018-06-20T16:31:45,834][INFO ][o.e.b.BootstrapChecks    ] [rpi-1] bound or publishing to a non-loopback address, enforcing bootstrap checks

[2018-06-20T16:31:46,025][INFO ][o.e.n.Node               ] [rpi-1] closed

如果我从下面的配置中删除 network.publish_host: 192.168.0.101，它将启动并尝试连接到另一个节点但会失败，因为它正在尝试使用 127.0.0.1 加入集群

我的配置:

#action.destructive_requires_name: true
xpack.ml.enabled: false
node.name:  c054915212b1
discovery.zen.ping.unicast.hosts: [192.168.0.108, 192.168.0.103, 192.168.0.104]
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
network.publish_host:  192.168.0.101
http.bind_host:  192.168.0.101
http.publish_host:  192.168.0.101
http.host:  192.168.0.101

在此版本之前，我在设置集群时从未遇到过问题。非常感谢您的帮助。

我也这样试过，结果一样；

action.destructive_requires_name: true
xpack.ml.enabled: false
node.name:  rpi-1
discovery.zen.ping.unicast.hosts: [192.168.0.108, 192.168.0.103, 192.168.0.104]
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
network.host:  192.168.0.101

每当您绑定(bind)到外部接口(interface)时，Elasticsearch 都会假定这是一个生产集群，并会进行一系列 Bootstrap 检查。也许你的内存没有被锁起来？尝试在 jvm.options 或使用命令行标志中为最小和最大 RAM 设置相同的值。
