OpenSearch开发环境安装Docker和Docker-Compose两种方式

本文主要是介绍OpenSearch开发环境安装Docker和Docker-Compose两种方式，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

简介

官网：

• https://opensearch.org/

• https://opensearch.org/docs/2.7/

这里我以2.7版本示例

前提docker已完成安装

我的业务数据是个json如下:

{"title": "The Wind Rises","created_on": "2023-11-22T09:28:48+00:00","type": "order","user": "eddie","price": 24.99
}

当添加到opensearch时，OpenSearch 会添加一些元数据如下：

{"_index": "<index-name>","_type": "_doc","_id": "<document-id>","_version": 1,"_source": {"title": "The Wind Rises","created_on": "2023-11-22T09:28:48+00:00","type": "order","user": "eddie","price": 24.99}
}

常用请求

在Dev Tools执行

创建映射

PUT laker-index
{"mappings": {"properties": {"title": {"type": "text"},"created_on": {"type": "date"},"type": {"type": "keyword"},"user": {"type": "keyword"},"price": {"type": "half_float"}}}
}

写入数据

POST _bulk
{"index":{"_index":"laker-index","_id":0}}
{"title":"The Wind Rises today is nice day","created_on":"2023-11-21T09:28:48+00:00","type":"order","user":"eddie","price":24.99}
{"index":{"_index":"laker-index","_id":1}}
{"title":"The Wind Rises","created_on":"2023-11-22T09:28:48+00:00","type":"sale","user":"eddie","price":4.99}
{"index":{"_index":"laker-index","_id":2}}
{"title":"The Wind Rises hello ","created_on":"2023-11-23T09:28:48+00:00","type":"order","user":"laker","price":34.99}
{"index":{"_index":"laker-index","_id":3}}
{"title":"The Wind Rises laker","created_on":"2023-11-22T09:28:48+00:00","type":"sale","user":"laker","price":14.99}
{"index":{"_index":"laker-index","_id":4}}
{"title":"The Wind Rises laker","created_on":"2023-11-21T09:28:48+00:00","type":"order","user":"laker","price":44.99}

查询数据

GET laker-index/_search
{"size": 1,"query": {"match": {"title": "Rises"}}
}

索引模板

PUT _index_template/<template name>
# 创建一个名为的模板daily_logs，并将其应用于名称与模式匹配的任何新索引logs-2020-01-*，并将其添加到my_logs别名中：
PUT _index_template/daily_logs
{"index_patterns": ["logs-2020-01-*"],"template": {"aliases": {"my_logs": {}},"settings": {"number_of_shards": 2,"number_of_replicas": 1},"mappings": {"properties": {"timestamp": {"type": "date","format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"},"value": {"type": "double"}}}}
}
# 如果您创建名为 的索引logs-2020-01-01，您可以看到它具有模板中的映射和设置：
PUT logs-2020-01-01
GET logs-2020-01-01
{"logs-2020-01-01": {"aliases": {"my_logs": {}},"mappings": {"properties": {"timestamp": {"type": "date","format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"},"value": {"type": "double"}}},"settings": {"index": {"creation_date": "1578107970779","number_of_shards": "2","number_of_replicas": "1","uuid": "U1vMDMOHSAuS2IzPcPHpOA","version": {"created": "7010199"},"provided_name": "logs-2020-01-01"}}}
}

安装

Docker方式

安装OpenSearch

1.拉取镜像

docker pull opensearchproject/opensearch:2.7.0

2.启动容器并暴露端口

docker run --name dev -d -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" -e "network.host=0.0.0.0" -e "plugins.security.disabled=false" opensearchproject/opensearch:2.7.0

• discovery.type=single-node 单节点模式
• network.host=0.0.0.0 在外部IP也能访问
• plugins.security.disabled=true 禁用安全套件，就不用密码了（这里开发环境可以设置为true）

3.向端口 9200 发送请求。默认用户名和密码为admin。

curl https://localhost:9200 -ku 'admin:admin'

结果如下：

{"name" : "039dd59a68de","cluster_name" : "docker-cluster","cluster_uuid" : "rUa90awRQe2KKP7VxBmwxg","version" : {"distribution" : "opensearch","number" : "2.7.0","build_type" : "tar","build_hash" : "b7a6e09e492b1e965d827525f7863b366ef0e304","build_date" : "2023-04-27T21:43:09.523336706Z","build_snapshot" : false,"lucene_version" : "9.5.0","minimum_wire_compatibility_version" : "7.10.0","minimum_index_compatibility_version" : "7.0.0"},"tagline" : "The OpenSearch Project: https://opensearch.org/"
}

也可以这样配置

# 复杂docker容器中的配置到本地
docker cp 039dd59a68de:/usr/share/opensearch/config/opensearch.yml .
# vim opensearch.yml 修改内容
network.host: 0.0.0.0
discovery.type: single-node
plugins.security.ssl.http.enabled: false
plugins.security.disabled=true
# 再将文件复制到容器
docker cp ./opensearch.yml 039dd59a68de:/usr/share/opensearch/config/opensearch.yml
# 重新启动docker容器：
docker restart 039dd59a68de
# 查看日志
docker logs -f 039dd59a68de

安装OpenSearchDashboard

1.拉取镜像

docker pull opensearchproject/opensearch-dashboards:2.7.0

2.启动容器并暴露端口

docker run --name dev-dash -d -p 5601:5601 -e "server.host=0.0.0.0" -e 'OPENSEARCH_HOSTS=["https://10.1.77.53:9200"]' opensearchproject/opensearch-dashboards:2.7.0# 直接禁用安全套件，没有密码
docker run --name dev-dash -d -p 5601:5601 -e "server.host=0.0.0.0"  -e 'OPENSEARCH_HOSTS=["http://10.1.77.102:9200"]' -e "DISABLE_SECURITY_DASHBOARDS_PLUGIN=true" opensearchproject/opensearch-dashboards:2.7.0

• server.host=0.0.0.0 允许外部IP访问
• opensearch.hosts=[“http://10.1.77.53:9200”] 配置opensearch地址

也可以这样去改配置

# 复杂docker容器中的配置到本地
docker cp 40301ac292a7:/usr/share/opensearch-dashboards/config/opensearch_dashboards.yml .
# vim opensearch_dashboards.yml 修改内容
opensearch.hosts: [https://10.1.77.53:9200]
opensearch.username: admin
opensearch.password: admin
server.host: '0.0.0.0' 
# 再将文件复制到容器
docker cp ./opensearch_dashboards.yml 40301ac292a7:/usr/share/opensearch-dashboards/config/opensearch_dashboards.yml
# 重新启动docker容器：
docker restart 40301ac292a7
# 查看日志
docker logs -f 40301ac292a7

3.访问http://ip:5601/ 。默认用户名和密码为admin。

Docker-Compose方式

Docker-Compose安装

# 根据需要替换其中的版本，这里是 v2.21.0
sudo curl -L https://github.com/docker/compose/releases/download/v2.21.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
# 将可执行权限应用于二进制文件
sudo chmod +x /usr/local/bin/docker-compose
# 创建软链
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
# 测试是否安装成功
docker-compose --version
- Docker Compose version v2.21.0# 常用命令
# 自动完成包括构建镜像，（重新）创建服务，启动服务
docker-compose up
# 后台执行
docker-compose up -d
# 此命令将会停止 up 命令所启动的容器，并移除网络
docker-compose down 
# -v删除所有卷的选项
docker-compose down -vdocker-compose start
docker-compose stop
docker-compose version

1.设置主机环境

vm.max_map_count至少设置为 262144

# 检测当前值
cat /proc/sys/vm/max_map_count
# 要增加该值，请将以下行添加到/etc/sysctl.conf
vim /etc/sysctl.conf
vm.max_map_count=262144
# 然后运行sudo sysctl -p重新加载
sudo sysctl -p

2.下载docker-compose.yml文件

• docker-compose.yml

mkdir -p /user/laker/opensearch
cd /user/laker/opensearch
wget https://opensearch.org/samples/docker-compose.yml

3.启动docker-compose

# 启动完要看日志，等1-2分钟就差不多了，注意看日志问题
docker-compose up

4.验证

访问http://ip:5601/ 。默认用户名和密码为admin。

问题

问题1：IPv4 forwarding is disabled. Networking will not work

执行docker run时有个提醒

WARNING: IPv4 forwarding is disabled. Networking will not work.

这个警告提示 Docker 在你的主机上禁用了 IPv4 转发，这可能导致 Docker 容器无法正常工作。IPv4 转发是指将进入的网络流量从一个网络接口转发到另一个网络接口的功能。

为了解决这个问题，你可以启用 IPv4 转发。

解决方案：

1. 打开 IPv4 转发：

   sudo sysctl -w net.ipv4.ip_forward=1
   

2. 若要使该更改永久生效，编辑 /etc/sysctl.conf 文件，将 net.ipv4.ip_forward 的值设置为 1。

问题2：OpenSearch Dashboards 启用中文界面

在 opensearch_dashboards.yml中修改配置

#设置中文
i18n.locale: "zh-CN"
