mac 安装Mongodb数据库

           这个mongodb真的装了好久啊，网上东一句西一句的版本又都不一样。我是mac os 10.11.6。对于现在2018年来说我的版本已经比较老了。可是我又不想更新。我是用Brew 安装的具体命令：brew install mongodb。一开始提示xcode版本太老了不能安装。反正我也是各种搜索答案。然后就用一个命令

brew search mongodb查找可以安装的版本。

试了几个发现可以用brew 安装mongodb@3.4。于是成功安装了。

装了之后就需要配置路径，网上也是教程很多，语句又都不一样。都说用brew安装会有默认路径，但是我发现我的不是默认的安装路径。用

brew info mongodb@3.4

这个命令可以查看到很多相关信息。终端出现一大堆文字如图

mongodb@3.4: stable 3.4.14 (bottled) [keg-only]

High-performance, schema-free, document-oriented database

https://www.mongodb.org/

/usr/local/Cellar/mongodb@3.4/3.4.14 (19 files, 296MB)

From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/mongodb@3.4.rb

==> Dependencies

Build: go ✘, scons ✘

Recommended: openssl ✔

Optional: boost ✘

==> Requirements

Required: macOS >= 10.8 ✔

==> Options

--with-boost

Compile using installed boost, not the version shipped with mongodb

--with-sasl

Compile with SASL support

--without-openssl

Build without openssl support

==> Caveats

This formula is keg-only, which means it was not symlinked into /usr/local,

because this is an alternate version of another formula.

If you need to have this software first in your PATH run:

  echo 'export PATH="/usr/local/opt/mongodb@3.4/bin:$PATH"' >> ~/.bash_profile

To have launchd start mongodb@3.4 now and restart at login:

  brew services start mongodb@3.4

Or, if you don't want/need a background service you can just run:

  mongod --config /usr/local/etc/mongod.conf

bogon:~ lijuan$ 

配置路径我直接用了echo 'export PATH="/usr/local/opt/mongodb@3.4/bin:$PATH"' >> ~/.bash_profile

然后用语句brew services start mongodb@3.4来启动。

再之后直接输入  mongo就可以进入shell

mongoexport就可以导出，说明前面路径配置已经成功。

我安装了Robo 3T来当图形化界面，点击了Conection，反正第一次出不来就多点击几次，然后连接上了mongodb.
