在并行运行的 Ubuntu 上为 Elasticsearch 设置网络访问 [英] Setup network access for Elasticsearch on Ubuntu running on parallels
本文介绍了在并行运行的 Ubuntu 上为 Elasticsearch 设置网络访问的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个运行版本 20.04 的 ubuntu 服务器实例安装在 Mac 的并行上，但是我无法从网络上的其他设备访问它，只能从 ubuntu 实例访问.
I have an instance of ubuntu server running version 20.04 installed on parallels on a Mac however I am unable to access it from other devices on my network, only from the instance of ubuntu.
lsb_release -a 给出以下结果
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04 LTS
Release: 20.04
Codename: focal
我已经按照这里
我可以在 ubuntu 上运行 curl -X GET 'http://localhost:9200' 并得到以下输出
I can run curl -X GET 'http://localhost:9200' on ubuntu and get the following output
{
"name" : "dev",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "u4Xx8JDyTdaWv_HsYK6xXA",
"version" : {
"number" : "7.6.2",
"build_flavor" : "default",
"build_type" : "deb",
"build_hash" : "ef48eb35cf30adf4db14086e8aabd07ef6fb113f",
"build_date" : "2020-03-26T06:34:37.794943Z",
"build_snapshot" : false,
"lucene_version" : "8.4.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
如果我运行 hostname -I 我得到 10.211.55.11 fdb2:2c26:f4e4:0:21c:42ff:fee9:e2c5 这是主机的 IP 地址ubuntu 实例.
If I run hostname -I I get 10.211.55.11 fdb2:2c26:f4e4:0:21c:42ff:fee9:e2c5 which is the IP address of the ubuntu instance.
但是，当我从 Mac 运行 curl -X GET 'http://10.211.55.11:9200' 时，我得到以下结果 curl: (7) Failed to connect to 10.211.55.11 端口 9200:连接被拒绝
However when I run curl -X GET 'http://10.211.55.11:9200' from my Mac I get the following result curl: (7) Failed to connect to 10.211.55.11 port 9200: Connection refused
如何从我网络上的其他设备访问我的 Elasticsearch 实例?
sudo ufw status 给我以下规则

/etc/elasticsearch/elasticsearch.yml 包含以下内容
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 0.0.0.0
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
添加 network.host:0.0.0.0
将上述行添加到 elasticsearch.yml 文件后，出现以下错误
After adding the above line to the elasticsearch.yml file I get the following error
Job for elasticsearch.service failed because the control process exited with error code.
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.
运行 systemctl status elasticsearch.service 给我以下错误信息
running systemctl status elasticsearch.service gives me the following error message

推荐答案
所以有几个问题，按照以下步骤应该可以解决问题:
So there were couple of issues and following below steps should solve the issue:
- 添加了
network.host:0.0.0.0允许在非环回地址(即 localhost 或 127.0.0.1)上暴露端口，以便局域网上的其他系统可以连接到其 IP 地址.立> - 添加了
discovery.type: single-node配置以避免生产引导程序检查.
- Added
network.host:0.0.0.0which allowed exposing port on non-loopback address(ie localhost or 127.0.0.1) so that other systems on LAN can connect to its IP address. - Added
discovery.type: single-nodeconfig to avoid the production bootstrap checks.
