I have a 2 nodes mongodb replica set in a cloud platform. The two nodes have their own intranet & internet address as follows:
Primary node: intranet 172.17.255.4 internet 39.128.114.219
Secondary node: intranet 172.17.255.6 internet 123.99.24.163
The mongod's listen port 14821 can be telnet in internet.
Then I add two dns records:
172.17.255.4 db2018-3.acmcoder.com
172.17.255.6 db2018-4.acmcoder.com
Now, I use nodejs to connect this replica set.
When the nodejs app using conn string
'mongodb://****:****@172.17.255.4:14821,172.17.255.6:14821/discuss?replicaSet=acmcoder&readPreference=secondary'
is deploy in the same intranet network with mongo server, it can work. But when I start the nodejs app using conn string
'mongodb://****:****@39.128.114.219:14821,123.99.24.163:14821/discuss?replicaSet=acmcoder&readPreference=secondary'
in my office with internet, it cant't work. Because the driver said the secondary address is db2018-4.acmcoder.com. How to fix this problem.
I have a temp way to add a record to the local hosts file in my computer.
123.99.24.163 db2018-4.acmcoder.com
But I think this is the correct way to resolve this problem.
