如何修复 'mongod[10993]: Error reading config file: No such file or directory' in Ubuntu 18.04

Question

我在为我的 Flask 应用程序设置 MongoDB 数据库时遇到问题，你们知道如何解决这个问题吗？

我已经尝试重新启动并重新安装它。

我知道它有点老了，但我在 Linux Mint 19.2 上遇到了同样的问题。

为了解决这个问题，我根据documentation - Configuration File Options 创建了配置文件“/etc/mongod.conf”。 从 Windows 复制的内容，它是通过安装自动创建的。

# mongodb.conf

# Where to store the data.
dbpath=/var/lib/mongodb

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

logappend=true

bind_ip = 127.0.0.1
#port = 27017

# Enable journaling, http://www.mongodb.org/display/DOCS/Journaling
journal=true

# Enables periodic logging of CPU utilization and I/O wait
#cpu = true

# Turn on/off security.  Off is currently the default
#noauth = true
#auth = true

# Verbose logging output.
#verbose = true

# Inspect all client data for validity on receipt (useful for
# developing drivers)
#objcheck = true

# Enable db quota management
#quota = true

# Set diagnostic logging level where n is
#   0=off (default)
#   1=W
#   2=R
#   3=both
#   7=W+some reads
#diaglog = 0

# Diagnostic/debugging option
#nocursors = true

# Ignore query hints
#nohints = true

# Disable the HTTP interface (Defaults to localhost:27018).
#nohttpinterface = true

# Turns off server-side scripting.  This will result in greatly limited
# functionality
#noscripting = true

# Turns off table scans.  Any query that would do a table scan fails.
#notablescan = true

# Disable data file preallocation.
#noprealloc = true

# Specify .ns file size for new databases.
# nssize = <size>

# Accout token for Mongo monitoring server.
#mms-token = <token>

# Server name for Mongo monitoring server.
#mms-name = <server-name>

# Ping interval for Mongo monitoring server.
#mms-interval = <seconds>

# Replication Options

# in replicated mongo databases, specify here whether this is a slave or master
#slave = true
#source = master.example.com
# Slave only: specify a single database to replicate
#only = master.example.com
# or
#master = true
#source = slave.example.com

# Address of a server to pair with.
#pairwith = <server:port>
# Address of arbiter server.
#arbiter = <server:port>
# Automatically resync if slave data is stale
#autoresync
# Custom size for replication operation log.
#oplogSize = <MB>
# Size limit for in-memory storage of op ids.
#opIdMem = <bytes>

# SSL options
# Enable SSL on normal ports
#sslOnNormalPorts = true
# SSL Key file and password
#sslPEMKeyFile = /etc/ssl/mongodb.pem
#sslPEMKeyPassword = pass

保存配置文件后重启mongodb服务：

sudo systemctl restart mongodb
