ubuntu 16.04安装mongodb

说明：由于ubuntu 14取消了对mongodb包的支持，因此，ubuntu 14必须通过源码包的形式进行安装。Ubuntu 16 TLS有mongodb的包的支持，可以直接安装

1. 导入密钥

root@ros-OptiPlex-3050:~# wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -
OK

2. 创建一个列表文件MongoDB

root@ros-OptiPlex-3050:~# echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list
deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.2 multiverse

3. 安装

root@ros-OptiPlex-3050:~# sudo apt-get install mongodb-org

 

root@block-PowerEdge-T30:~# nano /lib/systemd/system/mongod.service
