How to change default port of bitnami mongodb vm in microsoft azure

Question

I am deploying my NodeJS web application project in Microsoft azure. I am using Bitnami MongoDB vm for my server, the default port 27017 is not secured. Due to security reason I wanted to change some 27171, I have changed in mongo.conf file but its giving below error.

mongod.conf file-

 dbpath=/data/db #where to log logpath=/opt/bitnami/mongodb/log/mongodb.log logappend=true #bind_ip = 127.0.0.1 port = 27171 journal=true # Turn on/off security. Off is currently the default #noauth = true auth = true 

The error is

 MongoDB shell version v3.4.0 connecting to: mongodb:///opt/bitnami/mongodb/tmp/mongodb-27017.sock/ 2017-04-03T13:07:48.437+0000 W NETWORK [main] Failed to connect to /opt/bitnami/mongodb/tmp/mongodb-27017.sock:0, reason: No such file or directory 2017-04-03T13:07:48.462+0000 E QUERY [main] Error: couldn't connect to server/opt/bitnami/mongodb/tmp/mongodb-27017.sock:27017, connection attempt failed : connect@src/mongo/shell/mongo.js:234:13 @(connect):1:6 exception: connect failed

I have test in my lab, we can use this script to change the default port:

root@mongodb:/# mongod --port 49000 --dbpath /data/db

Here is the result:

root@mongodb:/data/db# mongo admin --username root -p ***** --port 49000
MongoDB shell version v3.4.2
connecting to: mongodb:///opt/bitnami/mongodb/tmp/mongodb-27017.sock/admin
MongoDB server version: 3.4.2

I ran into the same problem, and just found the fix. The mongo command isn't the normal mongo binary we have all come to love. It seems to be a custom one attempting to connect to the socket directly.

1. Change your mongodb config's port.

2. edit the custom mongo client script by running

    $ sudo vim `which mongo` 

3. Here is where they call the socket directly. Change the socket port and try running it again.

    - /opt/bitnami/mongodb/tmp/mongodb-27017.sock + /opt/bitnami/mongodb/tmp/mongodb-27171.sock 

Here is what mine looks like after editing:

#!/bin/sh
LC_ALL="C"
export LC_ALL
case "$@" in
  *--host*)
    exec $0.bin "$@"
    exit
esac
exec $0.bin --host /opt/bitnami/mongodb/tmp/mongodb-28018.sock "$@"

Good Luck!
