Phoenix 搭建流程整理

Phoenix 搭建流程整理

简介

Phoenix 是一个开源的HBASE SQL层应用程序。

安装流程

• CSD 激活

在 CM 主机上执行如下命令放入激活文件

mkdir -p /opt/cloudera/csd/
wget https://archive.cloudera.com/phoenix/6.2.0/csd/PHOENIX-1.0.jar -P /opt/cloudera/csd/

• Parcel 配置

进入 CDH 然后配置如下 parcel

https://archive.cloudera.com/phoenix/6.2.0/parcels/

安装分配并激活此 parcel 即可

• 安装服务

在 Parcel 配置完成后需要重启 scm-server 服务才可以进行安装

systemctl restart cloudera-scm-server

之后使用界面安装即可

测试

Python

pip3 install -i https://mirrors.cloud.tencent.com/pypi/simple --user phoenixdb

import phoenixdb
import phoenixdb.cursor

database_url = 'http://192.168.2.116:8765/'
conn = phoenixdb.connect(database_url, autocommit=True)

cursor = conn.cursor()
#cursor.execute("CREATE TABLE asd (id INTEGER PRIMARY KEY, username VARCHAR)")
cursor.execute("UPSERT INTO asd VALUES (?, ?)", (2, 'wq'))
#cursor.execute("SELECT * FROM asd")
#print(cursor.fetchall())

#cursor = conn.cursor(cursor_factory=phoenixdb.cursor.DictCursor)
#cursor.execute("SELECT * FROM USERS WHERE id=1")
#print(cursor.fetchone()['USERNAME'])
