pymongo.errors.ServerSelectionTimeoutError: 192.168.12.230:27017: [Errno 61] Connection refused

1.如果是链接虚拟机中的Mongodb时，打开配置文件mongod.conf。

vi /etc/mongod.conf

2.修改配置参数

找到

     net:

    port: 27017

    bindIp: 127.0.0.1  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

修改：

     net:

    port: 27017

    bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

3.重启mongdb

service mongod restart
