MongoDB 怎么查看日志文件？

默认情况下，MongoDB在此路径/var/log/mongodb/mongodb.log创建日志文件，如果找不到该日志文件，请检查MongoDB配置文件。

日志路径

检查在MongoDB的配置文件/etc/mongod.conf或/yourMongoDBpath/mongod.conf ，该logpath定义在何处记录。

/etc/mongod.conf

$ cat /etc/mongod.conf
# mongod.conf

# Where to store the data.

# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb3

#where to log
logpath=/var/log/mongodb/mongod.log

#...
