我正在尝试从VirtualBoxVM中运行的虚拟Raspberry PI连接到mysql。
使用Python脚本:
import mysql.connector
mydb = mysql.connector.connect(
host="MBP",
user="PI-2",
passwd="",
database="temperatureData"
)
mycursor = mydb.cursor()
sql = "INSERT INTO temperature (date, temp_celsius, temp_farenheit)
VALUES (%s, %s, %s)"
val = ("2019-01-14", "20")
mycursor.execute(sql, val)
mydb.commit()
print(mycursor.rowcount, "record inserted.")
但由于错误而失败:
1130: Host 'MBP' is not allowed to connect to this MySQL server
在Mysql(在Macbook上)中,我通过以下方式设置了用户:
CREATE USER 'PI-2'@'127.0.0.1' IDENTIFIED BY 'PI-2';
GRANT ALL PRIVILEGES ON *.* TO 'PI-2'@'127.0.0.1' WITH GRANT OPTION;
(使用127.0.0.1,因为我在VM内部使用NAT-如此处所述:how to get the ipaddress of a virtual box running on local machine)
my.cnf文件:
# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from localhost
# bind-address = 127.0.0.1
bind-address = 0.0.0.0
更新:
在MBP上输出ifconfig
:
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
[ ... ]
在VM上:
eth0 Link encap:Ethernet HWaddr 08:00:27:41:cb:b4
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0
inet6 addr: fe80::ef2d:bd28:6834:9191/64 Scope:Link
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:65536 Metric:1
答案 0 :(得分:0)
使用此命令授予特权:GRANT ALL PRIVILEGES ON *.* TO 'PI-2'@'MBP' WITH GRANT OPTION;
它允许MySQL接受来自名为MBP的主机的连接。
