安装 MongoDB (Ubuntu 16.04)

1. Install MongoDB (3.4)

1.1 Import the public key used by the package management system

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6

1.2 Create a list file for MongoDB

$ echo "deb [ arch=amd64,arm64 ] http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

1.3 Reload local package database

$ sudo apt-get update

1.4 Install the MongoDB packages

$ sudo apt-get install -y mongodb-org

1.5 The MongoDB instance stores its data files in /var/lib/mongodb and its log files in /var/log/mongodb by default, and runs using the mongodb user account. You can specify alternate log and data file directories in /etc/mongod.conf

2. Start / Stop / Restart MongoDB

$ sudo service mongod start
$ sudo service mongod stop
$ sudo service mongod restart

3. Completely remove MongoDB

$ sudo service mongod stop
$ sudo apt-get purge mongodb-org*
$ sudo rm -r /var/log/mongodb
$ sudo rm -r /var/lib/mongodb

4. 安装后遇到的问题

4. 1 mongod启动失败

• 查看日志信息（这个路径是默认的日志路径，可以在配置文件中修改）

$ tail -f /var/log/mongodb/mongod.log

• 如果log中提示Failed to unlink socket file /tmp/mongodb-27017.sock

$ rm /tmp/mongodb-27017.sock

4.2 无法从其他机器的客户端连接mongo服务

Always remember to edit the /etc/mongod.conf file and set your bind_ip = 0.0.0.0 in order to make connections externally.
