Ubuntu16.04 Mongodb搭建

1.为软件包管理系统导入公钥。

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

2、为MongoDB创建列表文件

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

3、更新软件源并安装mongodb

sudo apt-get updatesudo apt-get install -y mongodb-org

4、启动mongodb

sudo service mongod startmongo

出现箭头则启动成功

5、遇到的问题
错误：Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
Error: couldn’t connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed

解决方法：

删除mongod.lock

sudo rm /var/lib/mongodb/mongod.locksudo service mongod restart

删除完后仍然连接失败，重启虚拟机后连接成功
