mongoDB的简单配置

数据库配置

1. 安装mongoDB，不在赘述，不明白的goole

2. 创建数据库日志文件夹:
   在终端输入： sudo mkdir -p /data/db

3. 给予数据库日志文件夹操作权限
   在终端输入： sudo chown -R 用户名 /data/db

4. 进入mongodb 的 "bin"目录，使用命令“./mongod”启动mongoDB server，启动成功后最后一行应该是端口号，如配图，出现配图就能肯定你的Mongodb已经安装成了

tips: 查找bin路径的时候，有时候会忘记具体路径，因为我是用brew安装的，所以我用
brew info mongodb 查找安装信息的时候能找到其配置文件的路径，进而找到bin路径为/usr/local/bin

tip2017nov22：这里最好在.bash_profile中配置一下，具体可以看我的博客

5. 新建终端标签，并输入./mongo 登陆到数据库

6. 下面你可以任意操纵这个数据库了是不是很简单啊，如配图

关于用户的一些设置

1. Start MongoDB without access control. (No need, if service already running)

$ mongod --port 27017 --dbpath /data/db1

2. Connect to the instance

$ mongo --port 27017

3. Create the user administrator.
   Add a user with the root role. For example, the following creates the user superAdmin on the admin database:

$ use admin
$ db.createUser(
  {
    user: "superAdmin",
    pwd: "admin123",
    roles: [ { role: "root", db: "admin" } ]
  })

4. Re-start the MongoDB instance with access control
   Add the security.authorization setting to the config file
   ubuntu: $ sudo vi /etc/mongod.conf
   osx with brew version: $ sudo vi /usr/local/etc/mongod.conf
   It may look like this

systemLog:
 destination: file
 path: /usr/local/var/log/mongodb/mongo.log
 logAppend: true
storage:
 dbPath: /usr/local/var/mongodb
net:
 bindIp: 127.0.0.1
security:
 authorization: enabled

Restart mongodb

ubuntu: $ sudo service mongod restart

osx with brew version: $ brew services restart mongodb

5. Connect to database instance with superAdmin access

$ mongo --port 27017 -u "superAdmin" -p "admin123" --
authenticationDatabase "admin"

6. Create user access (readWrite) for specific database

$ mongo --port 27017 -u "superAdmin" -p "admin123" --authenticationDatabase "admin"
$ use myAppDb
$ db.createUser(
  {
   user: "myAppDbUser",
   pwd: "myApp123",
   roles: [ "readWrite"]
  })

7. Try Connecting to the specific database with limited access

$ mongo --port 27017 -u "myAppDbUser" -p "myApp123" --authenticationDatabase "myAppDb"
