安装 5.6.4 后 ElasticSearch 无法启动

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

Nov 13 16:59:24 Mysite systemd[1]: elasticsearch.service: Failed with result 'exit-code'.

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
