我刚刚从https://www.elastic.co/downloads/elasticsearch通过 DEB（我使用 Debian 9）包使用以下命令：
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.6.4.deb
dpkg -i elasticsearch-5.6.4.deb
apt-get install openjdk-8-jre-headless
update-rc.d elasticsearch defaults 95 10
service elasticsearch start
但是 ElasticSearch 无法启动，这是日志：
● elasticsearch.service - Elasticsearch

但它没有说出任何有用的东西。
在配置文件中我仅更改了这一点：
network.host: 51.15.212.76
http.port: 9200
cluster.name: elasticsearch
node.name: "db-master"
node.master: true
node.data: true
更新：
我只是使用了默认设置并且它可以工作，问题出在这里：
Caused by: java.net.BindException: Cannot assign requested address
为什么？我正在使用我的 IP 地址（我复制了它）。我不想将它绑定到本地主机，因为我希望能够从不同的机器连接它。
ifconfig -a 的结果

答案1
51.15.212.76问题是你的服务器上没有。你的提供商可能会映射51.15.212.76->10.5.85.149
所以尝试一下
network.host: 10.5.85.149
或者最好绑定到所有接口
network.host: 0.0.0.0
答案2
我看到了您的更新。您不能使用此配置：
network.host: 51.15.212.76
因为您没有具有此 IP 地址的网络接口。
例如，您可以从 eth0 使用这个 10.5.85.149。
答案3
您需要从
network.host: 51.15.212.76
到
network.host: 0.0.0.0
并在elasticsearch.yml文件中添加以下配置
transport.host: localhost
transport.tcp.port: 9300
