python连接Phoenix | 易学教程

1、启动Phoenix监听端口

#启动，端口:8765
[root@node1 ~]# /opt/phoenix-4.11.0/bin/queryserver.py start
starting Query Server, logging to /tmp/phoenix/root-queryserver.log

[root@node1 ~]# netstat -ntlp |grep 8765
tcp6       0      0 :::8765                 :::*                    LISTEN      50094/java

2、phoenixdb

安装包

#phoenixdb包的版本要和phoenix对应，参考官网：

https://python-phoenixdb.readthedocs.io/en/latest/versions.html#version-0-7

#我的Phoenix是4.11，所以要安装0.7版本

>pip3 install phoenixdb==0.7

python脚本：

#!/usr/bin/env python
# encoding: utf-8

"""
@author:  'Administrator'
@contact:  
@time: 
"""
import phoenixdb
import phoenixdb.cursor


database_url = 'http://node1:8765/'
conn = phoenixdb.connect(database_url, autocommit=True)

cursor = conn.cursor()
cursor.execute("CREATE TABLE users (id INTEGER PRIMARY KEY, username VARCHAR)")
cursor.execute("UPSERT INTO users VALUES (?, ?)", (1, 'admin'))
cursor.execute("SELECT * FROM users")
print(cursor.fetchall())

但是我的脚本执行后，会报错，如下：

因为初学乍练，没有解决掉，希望知道解决办法的朋友给我留个言，多谢
