Can't initiate replica set in Ubuntu
提问by Italo Maia
Whenever I type: rs.initiate(), I get the following error message:
每当我输入: 时rs.initiate()，我都会收到以下错误消息：
{
"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.
我正在使用最新的 MongoDB 在 google-cloud-engine 下运行。
Any suggestions on how to solve this?

You could try passing a parameter to the .initiate()command.
您可以尝试将参数传递给.initiate()命令。
Like so:
像这样：
rs.initiate({_id:"yourReplSetName", members: [{"_id":1, "host":"yourHost:yourPort"}]})
This did the trick for me.
这对我有用。

Your VMHOSTNAME must be an alias for 127.0.0.1 in your /etc/hosts file to make it work.
您的 VMHOSTNAME 必须是 /etc/hosts 文件中 127.0.0.1 的别名才能使其工作。

The problem might be in your mongo config. Look for the following line and comment it out:
问题可能出在您的 mongo 配置中。查找以下行并将其注释掉：
#bindIp: 127.0.0.1 # Listen to local interface only, comment to listen on all interfaces.

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.
如果您在 /etc/hostnames 文件中找到 VMHOSTNAME 并且引用的 mongo 实例正在运行，则可能是端口号错误。就我而言，它是。分片通常从端口 27018 开始。

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.
是的，确切地说，或者您可以将您的主机名更改为指向 127.0.0.1 的 /etc/hosts 中已有的内容，例如 localhost。
With a mac you can do this by typing sudo scutil –-set HostName localhost.
使用 Mac，您可以通过键入sudo scutil –-set HostName localhost.
