前段时间，我写了一篇关于如何在 Mac OS X 上安装 MongoDB 的文章。然而，大多数开发通常发生在 Unix/Linux 机器上。所以今天我们将研究如何在 Linux 系统上安装 MongoDB。

在 Linux 上安装 MongoDB

MongoDB 的当前版本是 3.4.7，我将通过命令行安装 64 位版本。在 Linux 上安装 MongoDB 的步骤非常简单，只需按照以下终端命令下载并安装即可。

下载并提取 MongoDB 二进制文件

root@dev [/home/journal]# mkdir mongodb
root@dev [/home/journal]# cd mongodb/
root@dev [/home/journal/mongodb]# curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.4.7.tgz

将 MongoDB bin 目录添加到 PATH 变量

root@dev [/home/journal/mongodb]# mv mongodb-linux-x86_64-3.4.7 mongodb
root@dev [/home/journal/mongodb]# cd mongodb
root@dev [/home/journal/mongodb/mongodb]# echo $PATH

root@dev [/home/journal/mongodb/mongodb]# export PATH=$PATH:/home/journal/mongodb/mongodb/bin

root@dev [/home/journal/mongodb/mongodb]# mkdir data
root@dev [/home/journal/mongodb/mongodb]# cd bin
root@dev [/home/journal/mongodb/mongodb/bin]# ./mongod --dbpath /home/journal/mongodb/mongodb/data &

使用“ps”命令确认 MongoDB 正在运行

root@dev [/home/journal/mongodb/mongodb/bin]#
root@dev [/home/journal/mongodb/mongodb/bin]# ps -eaf | grep mongo
root      7199 28009  0 14:09 pts/0    00:00:00 grep mongo
root     30387 28009  0 13:56 pts/0    00:00:02 ./mongod --dbpath /home/journal/mongodb/mongodb/data
root@dev [/home/journal/mongodb/mongodb/bin]#

就这样，我们的 MongoDB 安装在 Linux 机器上，运行良好。但是，您可能希望通过用户配置文件（即 .bash_profile 或 .profile）导出 PATH，这样退出终端后它就不会消失。

执行 MongoDB 命令

现在让我们连接到 MongoDB 并运行一些 mongodb 命令以确保它正常运行。

root@dev [~]# cd /home/journal/mongodb/mongodb/bin/
root@dev [/home/journal/mongodb/mongodb/bin]# ./mongo
MongoDB shell version: 3.4.7
connecting to: test
> show dbs
admin  (empty)
local  0.078GB
> use journaldev
switched to db journaldev
> db.names.save({"id":123,"name":"Pankaj"})
WriteResult({ "nInserted" : 1 })
> db.names.find()
{ "_id" : ObjectId("53df918adbef24e88560fa5b"), "id" : 123, "name" : "Pankaj" }
> db.datas.save({})
WriteResult({ "nInserted" : 1 })
> show collections
datas
names
system.indexes
> show dbs
admin       (empty)
journaldev  0.078GB
local       0.078GB
> exit
bye
root@dev [/home/journal/mongodb/mongodb/bin]#

如您所见，一切似乎都很顺利，我能够从 MongoDB 数据库保存和检索数据。如果您退出启动 mongodb 的终端，它将停止。使用nohup命令启动它，这样即使关闭终端它也不会停止。MongoDB下载页面
