我正在尝试让 mongoDB 在 Arch 下运行。
但是,我只能以 root 身份启动它或使用systemctl
默认路径。
我想做的是更改默认数据路径
/data/db
到
/home/manuel/ExtDrive/Data/mongodb
并使用 运行它systemctl
。
正如 ExtDrive 所示,这是通过 SATA(而非 USB)连接的 ext4 格式驱动器。
一旦我更改 mongoconfig 中的路径,服务就会开始失败:

该目录的权限是:
drwxr-xr-x 4 mongodb daemon 4.0K Jan 11 19:37 mongodb
这是我的 mongo 配置:
storage:
dbPath: "/home/manuel/ExtDrive/Data/mongodb/"
journal:
enabled: true
net:
port: 27017
bindIp: 127.0.0.1
为什么它可以在标准路径下完美运行,但一旦指定替代路径就停止工作?
