mongoDB error: Error: failed to connect to [localhost:27017]
提问by user13476
I'm trying to install habitrpglocally but I keep getting a mongoDB error after typing node src/seed.js:
我正在尝试在本地安装habirrpg，但在输入后我不断收到mongoDB错误node src/seed.js：
Error: failed to connect to [localhost:27017]
I saw on other questions with the same error people have suggested typing in 'mongod' and that fixes it by creating a local server. I get the error:
我在其他问题上看到了同样的错误，人们建议输入“mongod”并通过创建本地服务器来修复它。我收到错误：
-bash: mongod: command not found
Can't figure out what's wrong. Any ideas?
无法弄清楚出了什么问题。有任何想法吗？

Open CMD (In Windows) or terminal (In Ubuntu).
type command >cd PATH_FOR_MONGODB_BIN_FOLDER
cd C:\Program Files\MongoDB\Server\3.2\bin
for ubuntu command will be same :
cd /home/MongoDB/Server/3.2/bin
then type command >mongod --dbpath PATH_FOR_DATA_FOLDER
mongod --dbpath C:\data\db
For ubuntu command will be :
./mongod --dbpath /home/data/db
you can specify any folder as data folder.
Wait till CMD or Terminal shows "waiting for connections"
2016-09-01T21:38:33.170+0530 I NETWORK [initandlisten] waiting for connections on port 27017
Then open new CMD or terminal window.
type command >cd PATH_FOR_MONGODB_BIN_FOLDER ( same as step 3 )
cd C:\Program Files\MongoDB\Server\3.2\bin
Don't close previous window of cmd or teminal.
then run mongodb by typing "mongo" in windows or "./mongo" in ubuntu
mongo
For ubuntu
./mongo
After mongodb run successfully you can close previous CMD window.
打开 CMD（在 Windows 中）或终端（在 Ubuntu 中）。
键入命令 >cd PATH_FOR_MONGODB_BIN_FOLDER
cd C:\Program Files\MongoDB\Server\3.2\bin
对于 ubuntu 命令将是相同的：
cd /home/MongoDB/Server/3.2/bin
然后输入命令 >mongod --dbpath PATH_FOR_DATA_FOLDER
mongod --dbpath C:\data\db
对于 ubuntu 命令将是：
./mongod --dbpath /home/data/db
您可以指定任何文件夹作为数据文件夹。
等到 CMD 或终端显示“等待连接”
2016-09-01T21:38:33.170+0530 I NETWORK [initandlisten] 等待端口 27017 上的连接
然后打开新的 CMD 或终端窗口。
键入命令 >cd PATH_FOR_MONGODB_BIN_FOLDER（与步骤 3 相同）
cd C:\Program Files\MongoDB\Server\3.2\bin
不要关闭 cmd 或终端的前一个窗口。
然后通过在 Windows 中键入“mongo”或在 ubuntu 中键入“./mongo”来运行 mongodb
蒙戈
对于 ubuntu
./蒙戈
mongodb 运行成功后，您可以关闭之前的 CMD 窗口。

You don't have MongoDB installed. Follow the directions for your system to install it: http://docs.mongodb.org/manual/installation/
您没有安装 MongoDB。按照您系统的说明进行安装：http: //docs.mongodb.org/manual/installation/
From the habitRPG docs:
来自习惯RPG文档：
Before starting make sure to have MongoDB, NodeJS and npm and Git installed and set up.
在开始之前，请确保安装并设置了 MongoDB、NodeJS 和 npm 以及 Git。

I think that you don't have an environmental variable declared. Assuming that your MongoDB installation is C:\ProgramFiles\MongoDB\Server\YOUR_VERSION_NUMBER\, you should just add the binfolder path of that version of MongoDB to your PATH system environment variable.
我认为您没有声明环境变量。假设您的 MongoDB 安装是C:\ProgramFiles\MongoDB\Server\YOUR_VERSION_NUMBER\，您应该只bin将该版本的 MongoDB的文件夹路径添加到您的 PATH 系统环境变量中。
Here's a link where you can find the way to do that without complications : http://www.computerhope.com/issues/ch000549.htm

I got this issue because I didn't have MongoDB. SO Installed MongoDB and tried to run node application and it worked.
我遇到这个问题是因为我没有 MongoDB。所以安装了 MongoDB 并尝试运行节点应用程序并且它工作正常。
If you don't have MongoDB then follow below steps to install and enjoy
如果您没有 MongoDB，请按照以下步骤安装并享受
Commands :
命令：
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
$ echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
$ sudo apt-get update
$ sudo apt-get install -y mongodb-org
then type mongo in terminal and if you will get console for mongo then its done.
然后在终端中输入 mongo ，如果你会得到 mongo 的控制台，那么它就完成了。

After installing MongoDb you have to add the directory "data\db" under the C:\ directory, then you should start the mongod.exe
安装完MongoDb后需要在C:\目录下添加data\db目录，然后启动mongod.exe
