Whenever I type: rs.initiate(), I get the following error message:
{
"info2" : "no configuration explicitly specified -- making one",
"me" : "VMHOSTNAME:27017",
"ok" : 0,
"errmsg" : "No host described in new configuration 1 for replica set rs0 maps to this node",
"code" : 93
}
I'm running under google-cloud-engine with latest MongoDB.
Any suggestions on how to solve this?
You could try passing a parameter to the .initiate() command.
Like so:
rs.initiate({_id:"yourReplSetName", members: [{"_id":1, "host":"yourHost:yourPort"}]})
This did the trick for me.
Your VMHOSTNAME must be an alias for 127.0.0.1 in your /etc/hosts file to make it work.
The problem might be in your mongo config. Look for the following line and comment it out:
#bindIp: 127.0.0.1 # Listen to local interface only, comment to listen on all interfaces.
Yeah, exactly, or you can change your hostname to something that is already in your /etc/hosts pointing to 127.0.0.1 such as localhost.
With a mac you can do this by typing sudo scutil –-set HostName localhost.
If you find the VMHOSTNAME in the /etc/hostnames file and the referenced mongo instance is running then its possibly a port number error. In my case it was. Shards tipically started at port 27018.
