Ubuntu安装mongodb

直接去官网找：https://www.mongodb.com/download-center#community

但是发现下载太慢，看下官网的说明：

Install MongoDB Community Edition on Ubuntu

PLATFORM SUPPORT

MongoDB only provides packages for 64-bit LTS (long-term support) Ubuntu releases. For example, 12.04 LTS (precise), 14.04 LTS (trusty), 16.04 LTS (xenial), and so on. These packages may work with other Ubuntu releases, however, they are not supported.

了解Ubuntu有3种，结合自己用的版本，选择xenial，

去清华大学镜像网站下载速度会快很多，选择3.4.7，最新版进行下载，官网的最新版也是3.4.7： https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1604-3.4.7.tgz

dahu@dahu-desktop:/usr/local/mongodb$ ls
mongodb-org_3.4.7_amd64.deb         mongodb-org-shell_3.4.7_amd64.deb
mongodb-org-mongos_3.4.7_amd64.deb  mongodb-org-tools_3.4.7_amd64.deb
mongodb-org-server_3.4.7_amd64.deb

安装：这一步也可以参考官网给出的安装方式

检查是否正常：发现进程中有mongodb了

dahu@dahu-desktop:/usr/local/mongodb$ sudo service mongod start 
dahu@dahu-desktop:/usr/local/mongodb$ top

再看下log文件：OK的
