在Ubuntu上安装了MongoDb,说它没有安装

按照网站上的分步说明在Ubuntu上安装MongoDb
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-linux/
我尝试运行mongo时收到以下错误. “程序’mongo’目前尚未安装.”

但它在目录中.

test@MongoDb1:~$mkdir -p mongodb
test@MongoDb1:~$ls

mongodb      mongodb-linux-x86_64-2.5.4.tgz

test@MongoDb1:~$cp -R -n mongodb-linux-x86_64-2.5.4/ mongodb
test@MongoDb1:~$cd mongodb
test@MongoDb1:~/mongodb$ls

mongodb-linux-x86_64-2.5.4

test@MongoDb1:~/mongodb$cd mongodb-linux-x86_64-2.5.4/
test@MongoDb1:~/mongodb/mongodb-linux-x86_64-2.5.4$ls

bin  GNU-AGPL-3.0  README  THIRD-PARTY-NOTICES

test@MongoDb1:~/mongodb/mongodb-linux-x86_64-2.5.4$cd bin/
test@MongoDb1:~/mongodb/mongodb-linux-x86_64-2.5.4/bin$ls

bsondump  mongodump    mongoimport  mongorestore  mongotop
mongo     mongoexport  mongooplog   mongos
mongod    mongofiles   mongoperf    mongostat

test@MongoDb1:~/mongodb/mongodb-linux-x86_64-2.5.4/bin$mongo

The program 'mongo' is currently not installed. You can install it by typing:
sudo apt-get install mongodb-clients

test@MongoDb1:~/mongodb/mongodb-linux-x86_64-2.5.4/bin$

解决方法

查看在 10gen installation doc安装mongodb及其所有依赖于Ubuntu的首选方法,添加10gen mongodb public GPG key并：

sudo apt-get install mongodb-10gen
