dbeaver软件

安装postgresql

sudo apt-get update
sudo apt-get install postgresql postgresql-client

修改postgresql密码,创建数据库

psql -U postgres
ALTER USER postgres WITH PASSWORD 'new_password';
CREATE DATABASE DB_NAME;
\q

允许数据库被远程访问

 点insert,加入这句到最后

host   all    all    0.0.0.0/0    md5

 服务器没啥事了，现在到自己的电脑打开dbeaver

 

填写服务器ip，端口，用户名，密码

 

表就在这了

 python远程连接数据库代码

import psycopg2 as pg
import random
import string



con = pg.connect(database="xxx", user="postgres", password="xx", host="x.x.x.x", port="5432")
cur = con.cursor()


def creat_tb():
    cur.execute('''CREATE TABLE Users(
        id INT primary key,
        name varchar(20)
);''')

    con.commit()


# creat_tb()


def fetch():
    cur.execute("SELECT * from Users")
    # rows = cur.fetchall()
    print(cur.fetchall())



def clear():
    cur.execute(f"TRUNCATE TABLE Users")
    con.commit()   
# clear()
def drop():
    cur.execute(f"DROP TABLE Users")
    con.commit()   

    
def insert(id, name):
    sql = "INSERT INTO Users (id, name) VALUES ('{}', '{}' )".format(id, name)
    cur.execute(sql)
    con.commit()
# insert(2, "Nix")
print(fetch())
