Centos下mongodb的安装与配置

安装MongoDB的方法有很多种，可以源代码安装，在Centos也可以用yum源安装的方法。

1、准备工作

运行yum命令查看MongoDB的包信息（正常是没有信息提示的，我这里已经按安装好了）

[root@localhost~]# yum info mongodb-org

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

Installed Packages

Name        : mongodb-org

Arch        : x86_64

Version     : 3.4.10

Release     : 1.el6

Size        : 0.0

Repo        : installed

From repo   : mongodb-org-3.4

Summary     : MongoDB open source document-oriented database system (metapackage)

URL         : http://www.mongodb.org

License     : AGPL 3.0

Description : MongoDB is built for scalability, performance and high availability, scaling from single server deployments to large, complex multi-site architectures. By leveraging in-memory

            : computing, MongoDB provides high performance for both reads and writes. MongoDB’s native replication and automated failover enable enterprise-grade reliability and operational

            : flexibility.

            :

            : MongoDB is an open-source database used by companies of all sizes, across all industries and for a wide variety of applications. It is an agile database that allows schemas to

            : change quickly as applications evolve, while still providing the functionality developers expect from traditional databases, such as secondary indexes, a full query language

            : and strict consistency.

            :

            : MongoDB has a rich client ecosystem including hadoop integration, officially supported drivers for 10 programming languages and environments, as well as 40 drivers supported

            : by the user community.

            :

            : MongoDB features:

            : * JSON Data Model with Dynamic Schemas

            : * Auto-Sharding for Horizontal Scalability

            : * Built-In Replication for High Availability

            : * Rich Secondary Indexes, including geospatial

            : * TTL indexes

            : * Text Search

            : * Aggregation Framework & Native MapReduce

            :

            : This metapackage will install the mongo shell, import/export tools, other client utilities, server software, default configuration, and init.d scripts.

（如果没有提示相关匹配的信息，） 说明你的centos系统中的yum源不包含MongoDB的相关资源，

2、增加源

vim /etc/yum.repos.d/mongodb-3.4.repo

输入下面的语句：

[mongodb-org-3.4]

name=MongoDB Repository

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/

gpgcheck=1

enabled=1

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

3、安装

yum install -y mongodb-org

4、启动Mongodb

service mongod start

以后有更新了执行yum update  mongodb-org 即可。

5、服务器配置

# mongod.conf

#where to log

logpath=/data/logs/mongodb/mongod.log

logappend=true #以追加方式写入日志

# fork and run in background

fork=true

#port=27017

dbpath=/data/mongo  #数据库文件保存位置

# location of pidfile

pidfilepath=/var/run/mongodb/mongod.pid

# Listen to local interface only. Comment out to listen on all interfaces.

bind_ip=10.81.85.229

# Disables write-ahead journaling

# nojournal=true

#启用定期记录CPU利用率和 I/O 等待

# Enables periodic logging of CPU utilization and I/O wait

#cpu=true

# 是否以安全认证方式运行，默认是不认证的非安全方式

# Turn on/off security.  Off is currently the default

#noauth=true

auth=true

# Verbose logging output.

#verbose=true

# Inspect all client data for validity on receipt (useful for

# developing drivers)

#objcheck=true

# Enable db quota management 启用数据库配额管理，默认每个db可以有8个文件，可以用quotaFiles参数设置

#quota=true

# Set oplogging level where n is

#   0=off (default)

#   1=W

#   2=R

#   3=both

#   7=W+some reads

#diaglog=0

# Ignore query hints

#nohints=true

# Enable the HTTP interface (Defaults to port 28017).

#httpinterface=true

# Turns off server-side scripting.  This will result in greatly limited

# functionality

#noscripting=true

# Turns off table scans.  Any query that would do a table scan fails.

#notablescan=true

# Disable data file preallocation.

#noprealloc=true

# Specify .ns file size for new databases.

# nssize=<size>

# Replication Options

# in replicated mongo databases, specify the replica set name here

#replSet=setname

# maximum size in megabytes for replication operation log

#oplogSize=1024

# path to a key file storing authentication info for connections

# between replica set members

#keyFile=/path/to/keyfile

配置授权登录

> use admin

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

登录数据库

mongo 127.0.0.1:27017/admin -u root -p

查询

> db.comlogs.find().count()

326466

PHP测试代码

<?php

$mongo = new Mongo("mongodb://root:123456@127.0.0.1:27017/admin");   //认证用户，这里的数据库，只启认证作用

$db = $mongo->selectDB('admin');  //选取数据库

$users= $db->selectCollection("test");

$cursor = $users->find();

foreach ($cursor as $id => $value) {

    echo "$id: "; print_r($value); echo "<br>";

}  

$document = array(

    "title" => "MongoDB",

    "description" => "database",

    "likes" => 100,

    "url" => "http://www.cnblogs.com/chenpingzhao"

);

$users->insert($document);

6、mongodb角色

  • 数据库用户角色：read、readWrite;

  • 数据库管理角色：dbAdmin、dbOwner、userAdmin；

  • 集群管理角色：clusterAdmin、clusterManager、clusterMonitor、hostManager；

  • 备份恢复角色：backup、restore；

  • 所有数据库角色：readAnyDatabase、readWriteAnyDatabase、userAdminAnyDatabase、dbAdminAnyDatabase
