mongodb 只能 连接127.0.0.1的IP地址问题解决

1、问题

        在实际开发中，数据库与数据库访问进程应该是在同一台物理机上，这样的访问效率比较高，现实中不同的物理机访问数据库也是很常见的事情。mongodb默认配置只能连接127.0.0.1：27017的IP地址

如图：

10:26:03.037 INFO  [:27017] o.m.d.cluster                 :Exception in monitor thread while connecting to server 192.168.16.215:27017 com.mongodb.MongoSocketOpenException: Exception opening socket

2、解决办法

        找到mongodb安装目录，默认安装一般在C:\Program Files\MongoDB\Server\4.2\bin目录下，

找到mongod.cfg，将127.0.0.1 的IP改成bindIp: 0.0.0.0

# network interfaces
net:
  port: 27017
  #bindIp: 127.0.0.1
  bindIp: 0.0.0.0

3、重启电脑(或重启mongodb服务）
