Mac 安裝與配置mongodb

安裝 mongodb

install 以前，iTerm2 下用 brew 查看已安裝軟件、搜索 mongodb：

brew list
brew search mongodb

安裝 mongodb :

brew install mongodb

此處須要稍等一段時間，成功後會輸出如下即說明安裝成功：

$ brew install mongodb
Updating Homebrew...
==> Downloading https://homebrew.bintray.com/bottles/mongodb-3.4.0.sierra.bottle.1.tar.gz
######################################################################## 100.0%
==> Pouring mongodb-3.4.0.sierra.bottle.1.tar.gz
==> Caveats
To have launchd start mongodb now and restart at login:
  brew services start mongodb
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/3.4.0: 17 files, 261.4M

/usr/local/Cellar/mongodb這個就是MongoDB的路徑

進入環境配置

$ cd ~
$ vim .bash_profile

咱們須要把它放進環境裏：

export MONGO_PATH=/usr/local/Cellar/mongodb
export PATH=$PATH:$MONGO_PATH/bin

保存好，就啓動 mongodb

新建一個 iTerm2 窗口，執行 mongod 嘗試啓動 mongodb 但會失敗 exiting：

啓動 mongodb 以前，要先新建一個mongodb默認的數據寫入目錄：

$ mkdir -p /data/db
mkdir: /data/db: Permission denied (沒有權限拒絕訪問)

// sudo 並輸入密碼，從新新建目錄
$ sudo mkdir -p /data/db
Password:

給剛纔新建的數據庫目錄賦予權限：

sudo chown -R guojc /data

此時，執行 mongod 啓動 mongodb 服務

如今是成功了，等待鏈接，能夠Command + T 新建窗口打開

通常是能夠的，若是仍是exception: connect failed

當mongodb service 沒有運行的時候會發生這樣的錯誤

嘗試了新建一個/data/db 目錄，但不奏效

最後找到了以下方法解決

而後 在bash 輸入

brew services start mongodb

再輸入mongo進入數據庫

mongo

成功鏈接了：

bob@BobdeMacBook-Air:~$mongo

connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.3
