python 连接 Linux 的 redis 报错 （redis.exceptions.ConnectionError: Error 10061 ...由于目标计算机积极拒绝，无法连接）

未指定IP地址报错

😑

我的报错如下：

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File “D:\wjpythonwj\redis_1.py”, line 21, in
result = rs.set(‘name’,‘itcast’)
File “D:\python3\lib\site-packages\redis\commands\core.py”, line 2127, in set

raise ConnectionError(self._error_message(e)) redis.exceptions.ConnectionError: Error 10061 connecting to localhost:6379. 由于目标计算机积极拒绝，无法连接。.

👽学会看报错信息非常重要，我恰恰忽略了最后一句redis.exceptions.ConnectionError: Error 10061 connecting to localhost:6379. 由于目标计算机积极拒绝，无法连接

报错信息显示： 拒绝连接localhost:6379
此时应该使用ip add 查看Linux的IP地址和端口号（本地虚拟机VMware是虚拟出来的一层设备，与127.0.0.1有区别!!!）

[root@localhost /]# ip add

画重点：IP地址是<
