数据库相关说明 / 使用ubuntu apt安装 MongoDB 7.0社区版

如果是Windows想要安装MongoDB，点击此处下载Window安装包

如果是CentOS系统安装MongoDB，点击此处查看说明

本文中使用的ubuntu版本是22或者20，当你不确定当前Ubuntu版本时，使用命令查看：cat /etc/lsb-release

1、终端安装，检查是否安装gnupg和curl,如果显示指令不可用，安装即可

sudo apt-get install gnupg curl

2、导入MongoDB公共GPG密钥，运行以下命令即可

curl -fsSL https://pgp.mongodb.com/server-7.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \ --dearmor

3、为MongoDB创建列表文件

ubuntu 22使用如下命令

echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list

ubuntu 20使用如下命令

echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list

4、重新加载本地包数据库

sudo apt-get update

5、安装MongoDB包

sudo apt-get install -y mongodb-org

至此MongoDB就安装完成了

启动mongodb服务

sudo systemctl start mongod

验证MongoDB是否成功，查看MongoDB的运行状态

root@vultr:~# sudo systemctl status mongod ● mongod.service - MongoDB Database Server Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled) Active: active (running) since Sun 2025-12-28 01:43:19 UTC; 41s ago Docs: https://docs.mongodb.org/manual Main PID: 3091 (mongod) Memory: 133.0M CPU: 574ms CGroup: /system.slice/mongod.service └─3091 /usr/bin/mongod --config /etc/mongod.conf

6、开始使用MongoDB

root@vultr:~# mongosh Current Mongosh Log ID: 69508c6814495c25da8de665 Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+2.5.10 Using MongoDB: 7.0.28 Using Mongosh: 2.5.10 For mongosh info see: https://www.mongodb.com/docs/mongodb-shell/ To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy). You can opt-out by running the disableTelemetry() command. ------ The server generated these startup warnings when booting 2025-12-28T01:43:19.885+00:00: Using the XFS filesystem is strongly recommended with the WiredTiger storage engine.

7、可选配置，修改默认端口和希望外网访问，vim /etc/mongodb.conf，或者vim /etc/mongod.conf

找到以下配置项，vim下按字母 i 输入进行文件修改

修改端口，修改port：27017，如修改成port: 37017

外网访问，修改为bind_ip：0.0.0.0

修改完成按Esc，再按Shift+:,然后输入“wq”,保存文件并退出，然后重启mongodb服务

bind_ip = 0.0.0.0 port = 27017

开启mongodb服务 sudo systemctl start mongod 停止mongodb服务 sudo systemctl stop mongod 重启mongodb服务 sudo systemctl restart mongod 设置开机自启 sudo systemctl enable mongod 使用“mongo --port 28017”进入mongo shell

好了，至此MongoDB就安装好了，默认端口是27017
