Am instalat MongoDB pe VPS, CentOS, ma pot conecta la el local de pe VPS dar nu remote cu MongoVUE remote, imi da eroarea:

Connection was refused
Unable to connect to server 89.44.47.85:27017: Object reference not set to an instance of an object…
Type: MongoDB.Driver.MongoConnectionException
Stack: at MongoDB.Driver.Internal.DirectMongoServerProxy.Connect(TimeSpan timeout, ReadPreference readPreference)

Am rulat netstat -tunap

tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 12314/mongod

procesul e ok asculta pe portul care tb.

am deschis portul cu iptables desi nu cred ca era nevoie.

Inclin sa cred ca e tot firewall issue. poate SELinux? Incearca sa le faci disable temporar la firewall / Selinux si vezi daca te ajuta.

[root@adavidoaiei ~]# sestatus
SELinux status: disabled

am rulat si service iptables stop + chkconfig iptables off

[root@adavidoaiei ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

  1. http://stopdisablingselinux.com/
  2. VPS de unde? are IP direct asignat sau e nevoie sa faci port forward? Are firewall in fata? (GCE, AWS)
    log-urile ce zic?

Incearca si un ticket la host company legat de portul tau. Just in case…

OK, deci merge. Ai vre-un Mongo local? sa testezi conxiune remote din consola?
Pe net se zice ca MongoVue nu merge cu MongoDB 3

Nu am avut rabdare @ct27stf sa ma uit la toata prezentarea de 40 min de SELinux dar am gasit un rezumat pe site-ul de la CentOS http://wiki.centos.org/HowTos/SELinux
