请问显示超时是为什么，（mongo正常）

import pymongo

#pymongo.MongoClient,mongodb://192.168.110.129:27017
myclient = pymongo.MongoClient("mongodb://192.168.0.100:27017")
#当前指定的数据库的名称imooc
#如果没有插入数据，库和表都不会创建
mydb = myclient['imooc']
mycollection = mydb['pymongo_test']
#表.insert_one插入一条记录
mycollection.insert_one({"name":"imooc","flag":1,"url":"https://www.imooc.com"})

同学你好：

同学需要修改下配置文件中的bind_ip的值，将127.0.0.1改为0.0.0.0.并且重新启动一下服务。

如果是源码安装mongodb，则没有mongo.conf文件。可以在启动服务时绑定ip地址。

解决远程连接：

关闭防火墙：

临时关闭防火墙systemctl stop firewalld.service
永久关闭防火墙systemctl disable firewalld.service

开关机自启动设置
启动防火墙systemctl start firewalld.service
永久启动防火墙systemctl enable firewalld开关机自启动设置

重启mongo服务。

mongod --dbpath data/ --logpath log/mongo.log --port 27017 --bind_ip 0.0.0.0 --fork

如果没有解决：同学可以将代码中的IP地址改为127.0.0.1，使用用本地的MongoDB，没有区别。

如果我解决了同学的问题，请采纳！学习愉快^_^。

我是用的是源码安装，所以没有配置文件，请问如何咋启动服务是绑定ip地址，是用vi /etc/sysconfig/network-scripts/ifcfg-enp0s3这个语句吗？
