下载完安装包，并解压 tgz（以下演示的是 64 位 Linux上的安装） 。

curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz    # 下载
tar -zxvf mongodb-linux-x86_64-3.0.6.tgz                                   # 解压

mv  mongodb-linux-x86_64-3.0.6/ /usr/local/mongodb

MongoDB 的可执行文件位于 bin 目录下，所以可以将其添加到 PATH 路径中：

export PATH=<mongodb-install-directory>/bin:$PATH

创建数据库目录:

MongoDB 的数据存储在data目录的db目录下,但是这个目录在安装过程不会自动创建,

所系你需要手动创建data目录,并在data目录中创建db目录。

以下实例中我们将data目录创建于根目录下(/)。

注意：/data/db 是 MongoDB 默认的启动的数据库路径(--dbpath)。

mkdir -p /data/db

命令行中运行MongDB服务:

你可以再命令行中执行mongo安装目录中的bin目录执行mongod命令来启动mongdb服务。

注意：如果你的数据库目录不是/data/db，可以通过 --dbpath 来指定。

[root@adminset ~]# mkdir -p /data/db
[root@adminset ~]# mongod
