Question

我在尝试启动mongodb时收到此错误

2015-12-25T08:45:24.381+0000 I CONTROL  [initandlisten] MongoDB starting : pid=2132 port=27017 dbpath=/var/lib/mongodb 64-bit host=sulubuntu

这是我的配置文件

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: false
  engine:
  mmapv1:
    smallFiles: true
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1

如果我注释掉这些值，错误就会消失：engine，mmapv1，smallFiles

这看起来像配置错误，但我只是遵循编写配置文件found here

Answer 1

我认为您的问题是，如果您指定它，则不能将\n键留空。换句话说，它默认为storage.engine，但前提是您根本不添加它。

这是我在我的服务器上的工作配置：

mmapv1

对于MongoDB 3.0，引擎密钥可以省略，因为它默认为systemLog: destination: file path: "/var/log/mongodb/mongod.log" logAppend: true storage: mmapv1: smallFiles: true engine: mmapv1 journal: enabled: true dbPath: "/var/lib/mongodb" net: bindIp: 127.0.0.1 port: 27017，但从3.2开始它默认为mmapv1，我建议将其显式化并避免在升级时出现问题...

使用samllFiles存储引擎mmapv1的mongodb配置错误
