I'm not a Go guy, just need to use a plugin written in Go and I'm having some trouble between plugin and MongoDB.
The error is:
server selection error: server selection timeout
current topology: Type: Unknown
Servers:
Addr: localhost:27017, Type: Unknown, State: Connected, Avergage RTT: 0, Last error: dial tcp 127.0.0.1:27017: connect: connection refused
exit status 1
My configuration:
time=“2019-09-03T16:29:35Z” level=debug msg=“Host: ip-XXX-XX-XX-XXX.sa-east-1.compute.internal”
time=“2019-09-03T16:29:35Z” level=debug msg=“Port: 27017”
time=“2019-09-03T16:29:35Z” level=debug msg=“Username: user”
time=“2019-09-03T16:29:35Z” level=debug msg=“Password: user123*”
time=“2019-09-03T16:29:35Z” level=debug msg=“DBName: dbBackend”
The plugin snippet that performs the connection:
addr := fmt.Sprintf("mongodb://%s:%s", m.Host, m.Port)
to := 60 * time.Second
opts := options.ClientOptions{
ConnectTimeout: &to,
}
opts.ApplyURI(addr)
if m.Username != "" && m.Password != "" {
opts.Auth = &options.Credential{
AuthSource: m.DBName,
Username: m.Username,
Password: m.Password,
PasswordSet: true,
}
}
client, err := mongo.Connect(context.TODO(), &opts)
if err != nil {
return m, errors.Errorf("couldn't start mongo backend. error: %s
", err)
}
err1 := client.Ping(context.TODO(), nil)
if err1 != nil {
log.Fatal(err1) // error happens here
}
log.Debugf("MONGO CONNECTED")
m.Conn = client
return m, nil
I just can't realize why the mongo driver is looking on localhost if I'm setting the address of my mongoDB server.
EDIT 1
My db has replica set configured only to use change streams.
This is my RS configuration:
{
"_id" : "rs0",
"version" : 69559,
"protocolVersion" : 1,
"writeConcernMajorityJournalDefault" : true,
"members" : [
{
"_id" : 0,
"host" : "localhost:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : 0,
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"catchUpTimeoutMillis" : -1,
"catchUpTakeoverDelayMillis" : 30000,
"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("5cf684c3c0db3f53727d1bb4")
}
}
Any help solving it appreciated. Thanks
