我正在尝试创建一个远程mongodb服务器,以便在我的Java项目中使用。
我正在使用vagrant + ansible创建环境,但由于某种原因我无法建立连接。
我总是通过网络得到连接被拒绝的错误。同样的代码在本地主机上完美运行。
我正在使用vagrant box:chef/centos-6.5
,我的ansible任务如下:
我已经添加了iptables的例外规则:

sudo iptables -A INPUT -p tcp --dport 27017 -j ACCEPT
活跃的:

我定义了一个
MongoDbFactory
的Java代码:
public @Bean
MongoDbFactory mongoDbFactory() throws Exception {
MongoClient mongo = new MongoClient("<ip-of-machine>", 27017);
return new SimpleMongoDbFactory(mongo, "test");
}
但是每次尝试连接它时,我总是会遇到以下异常情况。com.mongodb.MongoTimeoutException: Timed out after 10000 ms while waiting for a server that matches AnyServerSelector{}. Client view of cluster state is {type=Unknown, servers=[{address=192.168.1.11:27017, type=Unknown, state=Connecting, exception={com.mongodb.MongoException$Network: Exception opening the socket}, caused by {java.net.ConnectException: Connection refused}}]
如果我从本地主机运行MongoDB并相应地更改IP,一切都正常。
谢谢
