Mongodb3.2版本基础

操作系统：CentOS6.5_64

官方网站：http://docs.mongoing.com/manual-zh/tutorial/install-mongodb-on-red-hat.html

1、安装版本3.2

添加yum源：vim /etc/yum.repos.d/CentOS-Base.repo （末尾添加mongodb3.2源）

[mongodb-org-3.2]

name=MongoDB Repository

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/

gpgcheck=1

enabled=1

gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc

 

2、处理警告：

三个警告提示：

** WARNING: You are running this process as the root user, which is not recommended.

** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.

** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.

处理警告（处理需要关闭服务）：

[root@kelong_1 ~]# cat /sys/kernel/mm/redhat_transparent_hugepage/enabled

[always] madvise never

[root@kelong_1 ~]# echo never >/sys/kernel/mm/redhat_transparent_hugepage/enabled

[root@kelong_1 ~]# cat /sys/kernel/mm/redhat_transparent_hugepage/enabled

always madvise [never]

 

[root@kelong_1 ~]# cat /sys/kernel/mm/transparent_hugepage/defrag

[always] madvise never

[root@kelong_1 ~]# echo never >/sys/kernel/mm/transparent_hugepage/defrag

[root@kelong_1 ~]# cat /sys/kernel/mm/transparent_hugepage/defrag

always madvise [never]

 

[root@localhost ~]# groupadd mongo

[root@localhost ~]# useradd -g mongo mongo

[root@localhost ~]# passwd mongo

赋予权限之前做好服务停止准备（若没有停止，及时查看日志/var/log/mongodb/mongod.log ）

[root@kelong_1 ~]# chown -R mongo:mongo /var/run/mongodb

[root@kelong_1 ~]# chown -R mongo:mongo /var/lib/mongo

[root@kelong_1 ~]# chown -R mongo:mongo /var/log/mongodb

[root@kelong_1 ~]# chown -R mongo:mongo /etc/

[root@kelong_1 ~]# su mongo

[mongo@kelong_1 root]$ mongod -f /etc/mongod.conf

[root@kelong_1 ~]# mongo

MongoDB shell version: 3.2.9

connecting to: test

>

 

3、添加用户认证

默认登录没有设置密码，需要创建，新版本设置密码账号如下

[root@localhost ~]# su sun

[sun@localhost root]$ mongod --shutdown --dbpath=/var/lib/mongo

[sun@localhost root]$ mongod -f /etc/mongod.conf --auth （启用认证）

[root@localhost ~]# mongo

MongoDB shell version: 3.2.9

> use admin

> db.createUser({user:'root',pwd:'root',roles:['userAdminAnyDatabase']})

设置成功后，再次登录进入

> use admin

switched to db admin

> db.auth('root','root')

1

设置远程账号连接：

服务器端更改绑定IP（或者注释绑定ip），重启服务。

[root@localhost ~]# vi /etc/mongod.conf

bind_ip=127.0.0.1 （注释该行代码）

[root@kelong_1 ~]# mongo 192.168.1.179:27017/admin -u root -p root （客户端连接）

windows端使用mongodb VUE连接。

 

4、启用认证案例：

192.168.1.124 root root admin

[mongo@localhost root]$ mongo

MongoDB shell version: 3.2.11

connecting to: test

> use admin

switched to db admin

> db.auth('root','root')

1

> use i2l

switched to db i2l

> db.createUser( { user: "test", pwd: "test", roles: [ { role: "readWrite", db: "i2l" } ] } )

[mongo@localhost root]$ mongo

MongoDB shell version: 3.2.11

connecting to: test

> use i2l

switched to db i2l

> db.auth('test','test')
