MongoDB 简易安装

在CentOS上尝试着安装MongoDB,单实例的安装。竟然也碰到一些奇奇怪怪的错误。

1 首先，MongoDB官方文档的repo例子中指向错误了。需要点进去文档中提供的最新的repo路径。我用3.4版本

baseurl = https://repo.mongodb.org/yum/redhat/7Server/mongodb-org/3.4/x86_64

2 在指定Log的时候，一定是指向一个文件，而不是一个文件夹路径

# mongod.conf# for documentation of all options, see:#   http://docs.mongodb.org/manual/reference/configuration-options/# where to write logging data.systemLog:  destination: file  logAppend: true  path: /MongoDB/Log/Mongodb.log#上面Path应该以一个具体的文件结尾，而不是/MongoDB/Log# Where and how to store data.storage:  dbPath: /MongoDB/Data/  journal:    enabled: true#  engine:#  mmapv1:#  wiredTiger:# how the process runsprocessManagement:  fork: true  # fork and run in background  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile# network interfacesnet:  port: 27017  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.

如果Log指向一个文件夹，会有如下错误：

about to fork child process, waiting until server is ready for connections.forked process: 4095ERROR: child process failed, exited with error number 1
