Python使用zdppy_es国产框架操作Elasticsearch实现增删改查

本套教程配套有录播课程和私教课程，欢迎私信我。

Docker部署ElasticSearch7

创建基本容器

docker run -itd --name elasticsearch -p 9200:9200 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms2g -Xmx2g"  elasticsearch:7.17.17

配置账号密码

容器中配置文件的路径：

/usr/share/elasticsearch/config/elasticsearch.yml

把配置文件复制出来：

# 准备目录
sudo mkdir -p /docker
sudo chmod 777 -R /docker
mkdir -p /docker/elasticsearch/config
mkdir -p /docker/elasticsearch/data
mkdir -p /docker/elasticsearch/log

# 拷贝配置文件
docker cp elasticsearch:/usr/share/elasticsearch/config/elasticsearch.yml /docker/elasticsearch/config/elasticsearch.yml

将配置文件修改为如下内容：

cluster.name: "docker-cluster"
network.host: 0.0.0.0
http.cors.enabled: true
http.cors.allow-origin: "*"
# 此处开启xpack
xpack.security.enabled: true

把本机的配置文件复制到容器里面：

docker cp /docker/elasticsearch/config/elasticsearch.yml elasticsearch:/usr/share/elasticsearch/config/elasticsearch.yml

重启ES服务：

docker restart elasticsearch

进入容器，设置es的密码：

docker exec -it elasticsearch bash
/usr/share/elasticsearch/bin/elasticsearch-setup-passwords interactive

执行上面的命令以后，输入y，会有如下提示，全都输入：zhangdapeng520

Please confirm that you would like to continue [y/N]y


Enter password for [elastic]: 
Reenter password for [elastic]: 
Enter password for [apm_system]: 
Reenter password for [apm_system]: 
Passwords do not match.
Try again.
Enter password for [apm_system]: 
Reenter password for [apm_system]: 
Enter password for [kibana_system]: 
Reenter password for [kibana_system]: 
Enter password for [logstash_system]: 
Reenter password for [logstash_system]: 
Enter password for [beats_system]: 
Reenter password for [beats_system]: 
Enter password for [remote_monitoring_user]: 
Reenter password for [remote_monitoring_user]: 
Changed password for user [apm_system]
Changed password for user [kibana_system]
Changed password for user [kibana]
Changed password for user [logstash_system]
Changed password for user [beats_system]
Changed password for user [remote_monitoring_user]
Changed password for user [elastic]

将会得到如下用户名和密码：

elastic
zhangdapeng520

apm_system
zhangdapeng520

kibana_system
zhangdapeng520

logstash_system
zhangdapeng520

beats_system
zhangdapeng520

remote_monitoring_user
zhangdapeng520

在宿主机中测试是否成功：

# 不带用户名密码
curl localhost:9200

# 带用户名密码
curl localhost:9200 -u elastic

建立连接

    "properties": {
        "id": {"type": "integer"},
        "name": {"type": "text"},
        "age": {"type": "integer"},
    }
}
edb.indices.create(index=index, mappings=mappings)

# 删除索引
edb.indices.delete(index=index)

新增数据

from es import Elasticsearch

# 连接es
