mongoDB,连接拒绝

Question

显示我的代码

conf.set( "mongo.input.uri" , "mongodb://127.0.0.1/stackoverflow.mrtest" );
conf.set( "mongo.output.uri" , "mongodb://127.0.0.1/stackoverflow.mrtest_out2" );

当主机是localhost或时,代码运行没有错误127.0.0.1.但是当主机更改为我的ip wlan0时192.168.1.102,它返回了以下错误

Cluster created with settings {hosts=[192.168.1.102:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}

我打开了端口27017.

sudo iptables -A INPUT -ptcp --dport 27017 -j ACCEPT

我的操作系统是Ubuntu 14.04.

我该如何解决？谢谢!

默认情况下,MongoDB仅绑定到loopback接口,这使得它只能从localhost访问.要更改它,您需要在mongod.conf文件中编辑此行;

# /etc/mongod.conf

# Listen to local interface only. Comment out to listen on all interfaces.
bind_ip = 127.0.0.1

您可以将其更改bind_ip = 127.0.0.1,192.168.1.102为允许LAN和本地连接,或者您可以删除或注释掉该行以允许所有连接.
