一. 安装 mongodb

1. 导入包管理系统使用的公钥 (Import the public key used by the package management system )

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

2. 为MongoDB创建一个列表文件 (Create a list file for MongoDB.)

/etc/apt/sources.list.d/mongodb-org-3.6.list使用适合您的Ubuntu版本的命令创建列表文件:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

3. 重新加载本地包数据库 (Reload local package database)

sudo apt-get update

4. 安装MongoDB包 (Install the MongoDB packages)

安装最新的稳定版本的MongoDB [Install the latest stable version of MongoDB]

sudo apt-get install -y mongodb-org

二. 运行mongodb服务

MongoDB实例默认存储其数据文件/var/lib/mongodb 及其日志文件/var/log/mongodb,并使用mongodb 用户帐户运行。您可以在中指定备用日志和数据文件目录/etc/mongod.conf。请参阅systemLog.pathstorage.dbPath获取更多信息。

如果更改运行MongoDB进程的用户,则 必须修改/var/lib/mongodb和 /var/log/mongodb目录的访问控制权限,以使该用户可以访问这些目录。

1. Start MongoDB.

sudo service mongod start

2. Verify(确认) that MongoDB has started successfully

验证mongod过程已成功启动通过检查日志文件的内容 /var/log/mongodb/mongod.log 对于这样一行

[initandlisten] waiting for connections on port 27017

mongod监听的端口。如果您修改了 配置文件中的net.port设置/etc/mongod.conf,端口可能会有所不同。

如果您修改了systemLog.path配置文件选项,请在您为该设置指定的位置查找日志文件。

您可能会在mongod 输出中看到非严重警告。只要你看到上面显示的日志行,你可以放心地忽略这些警告,在你最初的MongoDB评估。

3. Stop(停止) MongoDB.

根据需要,您可以mongod通过发出以下命令来停止进程: (As needed, you can stop the mongod process by issuing the following command:

sudo service mongod stop

4. Restart(重启) MongoDB.

sudo service mongod restart

5. Begin using MongoDB

Start a mongo shell on the same host machine as the mongod. Use the --host command line option to specify the localhost address and port that the mongod listens on:

mongo --host 127.0.0.1:27017

Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.
