将索引从一个集群（ip：192.168.0.1）迁移到另一个集群（ip：192.168.0.2），新集群需要配置白名单：

```yml

elasticsearch.yml

reindex.remote.whitelist: ['192.168.0.1:9200']
<br /> <br /> python
import json

import requests

import base64

迁移索引数据

def reindex(index):
print("{0} 索引正在迁移中".format(index))
jsonData = {
"source": {
"remote": {
"host": "<a href="http://192.168.0.1:9200"" rel="nofollow" target="_blank">http://192.168.0.1:9200",
"socket_timeout": "30s",
"connect_timeout": "30s",
"username": "elastic",
"password": "123456"
},
"index": index
},
"dest": {
"index": index
}
}
res = requests.post("<a href="http://192.168.0.2:9200/_reindex"" rel="nofollow" target="_blank">http://192.168.0.2:9200/_reindex", json=jsonData)
print(res.status_code)
print(res.content)

获取创建索引的语句

def getIndexDslJson(index):

username = "elastic"
password = "123456"
user_info_str = username + ":" + password
user_info = base64.b64encode(user_info_str.encode()) # 这个得到是个字节类型的数据
headers = {
"Authorization": "Basic {0}".format(user_info.decode()) # 这个就是需要验证的信息
}

res = requests.get("http://192.168.0.1:9200/{0}".format(index),
headers=headers)
print(res.status_code)
jsonIndex = json.loads(res.content)
print(jsonIndex[index])
del jsonIndex[index]['settings']['index']['creation_date']
del jsonIndex[index]['settings']['index']['provided_name']
del jsonIndex[index]['settings']['index']['uuid']
del jsonIndex[index]['settings']['index']['version']
jsonIndex[index]['settings']['index']['number_of_shards'] = 1
jsonIndex[index]['settings']['index']['number_of_replicas'] = 0
return jsonIndex[index]

创建索引

def createIndex(index, dslJson):
res = requests.put("http://192.168.0.2:9200/{0}".format(index), json=dslJson)
print(res.status_code)
print(res.content)


if name == 'main':

需要创建的索引

indexList = [
"index1_v1", "index2_v1"
]
for index in indexList:
dslJson = getIndexDslJson(index) # 获取原索引的结构
createIndex(index, dslJson) # 根据原索引结构，在新集群创建索引
reindex(index) # 将原集群索引迁移到新集群

```

创建es账号并授权

```

创建账号

adduser es

修改密码

passwd es

授权

chmod -v u+w /etc/sudoers
vim /etc/sudoers

新增

es ALL=(ALL) ALL

wq保存退出，这时候要记得将写权限收回

chmod -v u-w /etc/sudoers

```

创建docker网络

<br /> docker network create tx<br />

安装Elasticsearch

<br /> docker pull elasticsearch:6.7.1<br />

<br /> 在/home/es 中创建 config,data,plugins目录<br /> 在plugins目录中下载es相关插件，如：ik,pinyin等<br /> 在config中创建elasticsearch.yml配置，创建analysis\synonym.txt 同义词<br /> 给data配置权限 sudo chmod 777 /home/es/data/<br /> 将/home/es 目录及其子目录的用户改为es：chown -R es:root /home/es/<br />

```yml

elasticsearch.yml

cluster.name: "my-docker-cluster"
node.name: "es-node1"
network.host: 0.0.0.0
http.port: 9200

xpack.security.transport.ssl.truststore.path: elastic-certificates.p12

<br /> <br /> <br /> <br />
docker run -d --net tx --name my_elasticsearch -p 9201:9200 -p 9301:9300 -v /home/es/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /home/es/config/analysis:/usr/share/elasticsearch/config/analysis -v /home/es/config/elastic-certificates.p12:/usr/share/elasticsearch/config/elastic-certificates.p12 -v /home/es/data:/usr/share/elasticsearch/data -v /home/es/plugins:/usr/share/elasticsearch/plugins -e "discovery.type=single-node" -i -t --privileged=true elasticsearch:6.7.1
```

安装kibana

<br /> docker pull kibana:6.7.1<br />

```yml

kibana.yml配置文件

server.name: kibana
server.host: 0.0.0.0
elasticsearch.hosts: ["<a href="http://my_elasticsearch:9200"" rel="nofollow" target="_blank">http://my_elasticsearch:9200"]
