mongdb 安装

Posted 2021-01-30 小菜鸟！！

mongo

mongo安装

1. install

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

sudo echo "deb http://repo.mongodb.org/apt/debian wheezy/mongodb-org/3.0 main" > /etc/apt/sources.list.d/mongodb-org.list

sudo apt-get update

sudo apt-get install -y mongodb-org=3.0.5 mongodb-org-server=3.0.5 mongodb-org-shell=3.0.5 mongodb-org-mongos=3.0.5 mongodb-org-tools=3.0.5

2.ip，port，auth修改

cd /etc/

sudo vim /etc/mongod.conf

bind_ip = 0.0.0.0

port = 27017

auth = true

• 重启生效

/etc/init.d/mongod restart

• 说明：mongodb存储所有的用户信息在admin 数据库的集合system.users中，保存用户名、密码和数据库信息。mongodb默认不启用授权认证，只要能连接到该服务器，就可连接到mongod。若要启用安全认证，需要更改配置文件参数auth。

数据库用户添加

1.查看数据库

show dbs

如果提示错误信息：

[email protected]:/etc# mongo
MongoDB shell version: 3.0.5
connecting to: test
> show dbs
2018-12-26T12:03:01.524+0800 E QUERY    Error: listDatabases failed:{
        "ok" : 0,
        "errmsg" : "not authorized on admin to execute command { listDatabases: 1.0 }",
        "code" : 13
}
    at Error (<anonymous>)
    at Mongo.getDBs (src/mongo/shell/mongo.js:47:15)
    at shellHelper.show (src/mongo/shell/utils.js:630:33)
    at shellHelper (src/mongo/shell/utils.js:524:36)
    at (shellhelp2):1:1 at src/mongo/shell/mongo.js:47

执行如下,

use admin

db.auth("admin","admin")

> db.auth("admin","admin")
1
> show dbs
admin  0.078GB
local  0.078GB

• 注：有的版本中，无admin账号，需要自行创建，请参考其他资料

2.创建用户

use admin

db.createUser(
  {
    user: "root",
    pwd: "123456",
    roles: [ { role: "readWrite", db: "admin" } ]
  }
)

> db.createUser(
...   {
...     user: "root",
...     pwd: "123456",
...     roles: [ { role: "readWrite", db: "admin" } ]
...   }
... )
Successfully added user: {
        "user" : "root",
        "roles" : [
                {
                        "role" : "readWrite",
                        "db" : "admin"
                }
        ]
}

• 用户认证

  db.auth("root","123456")

  > db.auth("root","123456")
  1

3.给用户添加读写权限

db.auth("root", "123456")

db.grantRolesToUser("root", [ { role: "readWrite", db: "admin" } ])

4.注意

• 注，在mongo shell中执行，需要进入到use admin内，执行 db.auth("admin", "admin") 才能做其他操作

卸载

apt-get --purge remove mongodb*
