mongodb远程连接失败

 远程连接mongodb时 报错  连接被拒绝 ：java.net.ConnectException: Connection refused: connect

com.mongodb.MongoSocketOpenException: Exception opening socket at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:70) at com.mongodb.internal.connection.InternalStreamConnection.open(InternalStreamConnection.java:126) at com.mongodb.internal.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:117) at java.lang.Thread.run(Thread.java:748) Caused by: java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at com.mongodb.internal.connection.SocketStreamHelper.initialize(SocketStreamHelper.java:64) at com.mongodb.internal.connection.SocketStream.initializeSocket(SocketStream.java:79) at com.mongodb.internal.connection.SocketStream.open(SocketStream.java:65) ... 3 more

经检查 ip地址 和端口号都没有问题 查阅资料发现 mongodb默认只能支持本地连接  需要配置允许外界访问

在linux端的 自定义 配置文件内  加上 bind_ip=0.0.0.0 表示 允许任何ip访问

dbpath=/usr/local/mongodb/data/db logpath=/usr/local/mongodb/log/mongodb.log port=27017 fork=true auth=true bind_ip=0.0.0.0

注意:

 1. 在启动时 加载配置文件 否则 无法生效  ./mongod --config /usr/local/mongodb/etc/mongodb.conf

 2.配置文件的位置自拟在哪里都可以
