Ho installato mongo su machine1 (Ubuntu 14.04.3 LTS server
) nella mia rete locale. Ho anche aperto la porta 27017
come indicato nel this guida utilizzando i seguenti comandi:Impossibile collegarsi a mongo sul server remoto
sudo iptables -A INPUT -p tcp --destination-port 27017 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo iptables -A OUTPUT -p tcp --source-port 27017 -m state --state ESTABLISHED -j ACCEPT
regole attuali sono (iptables -L
):
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:27017 state NEW,ESTABLISHED
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp spt:27017 state ESTABLISHED
Ma io non sono in grado di connettersi a questa porta da machine2 (nella stessa rete):
$ mongo --host 192.168.0.108
MongoDB shell version: 3.0.4
connecting to: 192.168.0.108:27017/test
2016-01-23T18:02:14.848+0530 W NETWORK Failed to connect to 192.168.0.108:27017, reason: errno:61 Connection refused
2016-01-23T18:02:14.850+0530 E QUERY Error: couldn't connect to server 192.168.0.108:27017 (192.168.0.108), connection attempt failed
at connect (src/mongo/shell/mongo.js:181:14)
at (connect):1:6 at src/mongo/shell/mongo.js:181
exception: connect failed
Ho anche provato a verificare se la porta è stata aperta o meno:
$ nc -v 192.168.0.108 27017
nc: connectx to 192.168.0.108 port 27017 (tcp) failed: Connection refused
Non sono sicuro di ciò che mi manca. Deve essere un errore stupido mentre sto installando mongo per la prima volta. Aiuto di Pls.
Update (per i dubbi sollevati nelle risposte correnti)
- Già la sua esecuzione. Sono in grado di connettermi a mongo formando la stessa macchina ma non dall'altra macchina. Il demone è in esecuzione:
$ service mongod status mongod start/running, process 31205
e la porta è 27017$ sudo netstat -tulpn |grep 27017 tcp 0 0 127.0.0.1:27017 0.0.0.0:* LISTEN 31205/mongod
- Ho cambiato il
bind_ip
in0.0.0.0
e riavviato mongo. Ancora lo stesso errore sta arrivando.
Mongo registra:
$ cat /var/log/mongodb/mongod.log

Sarebbe possibile aggiungere i log del server mongod da qualche parte? Le 100 linee iniziali sarebbero sufficienti. – nobody
@nobody Aggiornato i registri mongo –
Spero che tu abbia già indizi dai log. – nobody
