1.下载mongodb系统包

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.2.4.tgz

2.解压压缩包

tar -zxvf mongodb-linux-x86_64-rhel70-3.2.4.tgz

3.将解压包改名为/usr/local/下的mongodb

mv mongodb-linux-x86_64-rhel70-3.2.4 /usr/local/mongodb

4.创建数据库目录

cd /usr/local/mangodb/bin

mkdir -p data/test/db

mkdir -p data/test/logs

5.创建配置文件 mongodb.conf

vi mongodb.conf

dbpath = /usr/local/mongodb/bin/data/test/db

logpath = /usr/local/mongodb/bin/data/test/logs/mongodb.log

port = 27017

fork = true

nohttpinterface = true

6.启动mongodb

./mongod –f mongodb.conf

7.查看 mongodb 进程：

ps -ef|grep mongodb

> use DATABASE_NAME

如果数据库不存在，则创建数据库，否则切换到指定数据库。

> use kingscc

switched to db laoA

> show dbs（ 查看都有什么数据库，里面没有数据的数据库不显示）

local 0.000GB

> db（显示当前的数据库）

kingscc

> db.laoA.insert({"name":"kingscc丶"})（往数据库插入数据）

WriteResult({ "nInserted" : 1 })

> db.dropDatabase()（首先先使用数据库，在进行删除）

删除当前数据库，默认为 test，你可以使用 db 命令查看当前数据库名。
