在mac上安装mongoDB一般两种方式: + 下载源码,解压,编译,配置,启动…(或者直接下载编译好的压缩包) + 使用brew install mongoDB (ps:可以指定版本)

lvdalin:~ lvdalin$ brew search mongodb-community
==> Formulae
mongodb/brew/mongodb-community           mongodb/brew/mongodb-community@3.4
mongodb/brew/mongodb-community-shell     mongodb/brew/mongodb-community@3.6
mongodb/brew/mongodb-community@3.2       mongodb/brew/mongodb-community@4.0
mongodb/brew/mongodb-community@4.2

lvdalin:~ lvdalin$ brew install mongodb-community@4.2
==> Installing mongodb-community from mongodb/brew
==> Downloading https://fastdl.mongodb.org/osx/mongodb-macos-x86_64-4.2.8.tgz

==> Caveats
To have launchd start mongodb/brew/mongodb-community now and restart at login:
  brew services start mongodb/brew/mongodb-community
Or, if you don't want/need a background service you can just run:
  mongod --config /usr/local/etc/mongod.conf
==> Summary
🍺  /usr/local/Cellar/mongodb-community/4.2.8: 21 files, 306.3MB, built in 7 seconds

看到上面的日志说明,已经安装成功 上面显示:Caveats 提示/警告信息 : 可以使用brew services start/restart mongodb ,也可以指定配置启动mongodb Summary 总结: 安装的路径为:/usr/local/Cellar/mongodb-community/4.2.8: 21,文件总大小:306.3MB, 安装时间:7秒. 第一次启动可能用到的步骤:

• 修改默认的数据文件存放路径 /data/db, 没有的话需要创建,同时修改目录所属用户

  lvdalin:bin lvdalin$ sudo mkdir -p /data/db
  lvdalin:bin lvdalin$ sudo chowm -R lvdalin /data/db

• 修改mongoDB配置文件mongod.conf(默认在usr/local/etc/下),修改数据文件存储位置

  lvdalin:etc lvdalin$ vim mongod.conf
  
  systemLog:
  destination: file
  path: /usr/local/var/log/mongodb/mongo.log
  logAppend: true
  storage:
  #dbPath: /usr/local/var/mongodb
  dpPath: /data/db
  net:
  bindIp: 127.0.0.1  #只允许本地的链接访问,如果允许远程访问 bindIp : 0.0.0.0                    

• mongodb加入环境变量

lvdalin:~ lvdalin$ vim .bash_profile
//加入到文件末尾 保存
export PATH="/usr/local/Cellar/mongodb-community/4.2.8/bin:$PATH"
//让环境变量生效
lvdalin:~ lvdalin$ source .bash_profile

启动mongodb

lvdalin:etc lvdalin$  brew services start mongodb/brew/mongodb-community


lvdalin:etc lvdalin$ mongod

启动客户端

lvdalin:etc lvdalin$ mongo
MongoDB shell version v4.2.8
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
MongoDB server version: 4.2.8
