ElasticSearch为何部署不成功？

Question

我已经安装了ElasticSearch.

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg
sudo apt-get install apt-transport-https
echo "deb [signed-by=/usr/share/keyrings/elasticsearch-keyring.gpg] https://artifacts.elastic.co/packages/8.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-8.x.list
sudo apt-get update && sudo apt-get install elasticsearch

也开启了防火墙

sudo firewall-cmd --add-port=9200/tcp --permanent
sudo firewall-cmd --reload
sudo  firewall-cmd --list-all
public
  target: default
  icmp-block-inversion: no

启动

sudo systemctl start  elasticsearch.service
sudo systemctl status  elasticsearch.service

我的本机ip

ifconfig 
inet 192.168.1.3
有很多省略

于是，我写这样的配置
sudo vim /etc/elasticsearch/elasticsearch.yml

cluster.name: my-application
node.name: node-1
node.attr.rack: r1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 192.168.1.3
http.port: 9200
discovery.seed_hosts: ["host1", "host2"]


xpack.security.enabled: true

xpack.security.enrollment.enabled: true

xpack.security.http.ssl:
  enabled: true
  keystore.path: certs/http.p12

xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12
cluster.initial_master_nodes: ["MiWiFi-R4A-srv"]

http.host: 0.0.0.0
transport.host: 0.0.0.0

也设置了账号，密码

adduser elasticsearch
passwd elasticsearch

用浏览器打开

为何部署不成功？

我输入了正确的账号，密码，cluster.initial_master_nodes: ["node-1"]，为何还是无法登录呢？

Answer 1

建议是贴一下启动日志会比较好。

根据已经有的信息，我猜你应该是要在浏览器中打开 https://192.168.1.3:9200 ，而不是 http://192.168.1.3:9200 （配置文件里面是开启 SSL ，所以这里应该是要用 https 协议访问）

另外 cluster.initial_master_nodes: ["MiWiFi-R4A-srv"] 这一行配置也存疑，这里应该是要设置成 ["node-1"] ，否则可能会导致启动时出现问题，因为设置错了会没法找到初始化的主节点。我猜测主要是因为这个原因导致了没有启动完成，所以这里能看到浏览器提示 ERR_ENPTY_RESPONSE。
