参照在 Ubuntu 上安装 MongoDB Community Edition - 数据库手册 v8.0 - MongoDB Docs
安装后，sudo systemctl start mongod启动失败。
sudo systemctl status mongod 结果：
mongod.service - MongoDB Database ServerLoaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)Active: failed (Result: signal) since Fri 2025-05-16 09:39:09 CST; 12min agoDocs: https://docs.mongodb.org/manualProcess: 2122273 ExecStart=/usr/bin/mongod --config /etc/mongod.conf --auth --port 27017 (code=killed, signal=ABRT)Main PID: 2122273 (code=killed, signal=ABRT)CPU: 558ms
确保了/var/lib/mongodb， /var/log/mongodb/mongod.log 读写权限正确。
查日志cat /var/log/mongodb/mongod.log发现报错：listenAddrs":"127.0.0.1:27017","error":"Address already in use
修改 /etc/mongod.conf
net:port: 27017bindIp: 127.0.0.1,::,0.0.0.0 #这个是有问题的
为
net:port: 27017bindIp: ::,0.0.0.0 # 这样就好了
