linux - 无法为旧的 dbPath 启动 mongodb 数据库

Question

今天我的 mongodb 数据库由于文件系统 inode 已满而停止。我删除了 var/www/html 目录中的旧文件并启动了 mongodb 数据库。但无法启动。我收到以下错误。

但我创建了另一个 dbPath:/var/lib/mongo2。然后我可以启动 mongodb 数据库。我无法启动旧的 dbPath

我尝试删除/tmp/mongodb-27017.sock。但没有成功

我正在运行 centos 7

请帮帮我

谢谢

Answer 1

如控制台输出所示，根本找不到您指定的路径。

2017-02-28T13:25:50.850+0000 I STORAGE  [initandlisten] exception in initAndListen: 29 Data directory /data/db not found., terminating

您(或默认脚本)提供的路径是/data/db。此绝对路径指的是根目录中名为 data 的文件夹。

确保文件夹 /data/db 存在，或者当之前指定了另一个路径时，传递那个路径。如果你想输入一个相对路径，你应该改用这个语法:./data/db 它将引用你当前运行的目录中的文件夹 data命令 in(使用 pwd 命令检查当前目录)。
