我正在尝试在我的服务器 Centos 5.6 上构建一个 mongo 副本集，该副本集将由装有 Ubuntu 8.10 和 mongodb 的 5 VB 设置。主要问题是我无法连接到虚拟机上的 mongo。
网络是通过带有转发端口的 NAT 设置的。
我有 Ubuntu 8.1 的镜像。下面是我创建框的方式
VBoxManage createvm --name "mongovb_03" --ostype Ubuntu --register
VBoxManage modifyvm "mongovb_03" --memory 2048 --acpi on --boot1 dvd --nic1 nat
VBoxManage modifyvm "mongovb_03" --pae on --cpus 2
VBoxManage storagectl "mongovb_03" --name "SATA Controller" --add sata --controller IntelAhci
VBoxManage storageattach "mongovb_03" --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium "ubuntu_8.vdi"
然后我使用 vboxtool 转发端口。

现在我可以通过 ssh 访问我的 vbox，如下所示：
ssh -p 2023 localhost
我也可以访问我的 Apache本地主机：8083或吟诵http://本地主机:8083/munin/index.html
问题是我无法访问 mongo。
我的 mongo.conf
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongodb.log
logappend=true
port=27017
journal=true
bind_ip=127.0.0.1
因此，当我尝试连接到 mongo 时，我得到：
mongo 127:0.0.1:27003

谢谢大家的帮助，我真的被困在这里了。

答案1
检查你的 mongodb.conf（在 ubuntu 上：/etc/mongodb.conf，不确定在 CentOS 上在哪里）并查看：
bind_ip = 127.0.0.1
如果是，请用“#”注释该行：
#bind_ip = 127.0.0.1
请注意，这可能会产生安全影响。
答案2
我不确定问题是什么，但这确实引起了我的注意
getaddrinfo("127:0.0.1")
那不应该是 127.0.0.1 吗？
