CentOS 6.3下快速安装MongoDB 3.2.1

原创 NoSQL 作者:wolfreturn 时间:2016-01-21 18:10:07 0 删除 编辑
MongoDB是一个基于分布式文件存储的数据库。由C++语言编写。旨在为WEB应用提供可扩展的高性能数据存储解决方案。
是一个介于关系数据 库和非关系数据库之间的产品,是非关系数据库当中功能最丰富,最像关系数据库的。他支持的数据结构非常松散,是类似json的bson格式,因此可以存储 比较复杂的数据类型。Mongo最大的特点是他支持的查询语言非常强大,其语法有点类似于面向对象的查询语言,几乎可以实现类似关系数据库单表查询的绝大 部分功能,而且还支持对数据建立索引。

MongoDB 是目前在IT行业非常流行的一种非关系型数据库(NoSql),其灵活的数据存储方式备受当前IT从业人员的青睐。MongoDB很好的实现了面向对象的 思想(OO思想),在MongoDB中 每一条记录都是一个Document对象。MongoDB最大的优势在于所有的数据持久操作都无需开发人员手动编写SQL语句,直接调用方法就可以轻松的 实现CRUD操作。本文介绍了如何快速安装mongodb供大家参考。

一、安装配置mongodb
useradd mongodb

Step 1: 设置系统环境及确保缺省端口27107可用
###当前环境
cat /etc/issue

# vi /etc/selinux/config
SELINUX=disabled

Step 2: 下载安装文件
下载地址: https://www.mongodb.org/downloads.
或者直接在命令提示符下使用curl命令下载
curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.1.tgz

Step 3: 解压下载的文件
# pwd
/home/mongo
# tar -xvf mongodb-linux-x86_64-rhel62-3.2.1.gz  ###注,本文直接从网站下载,所以文件为.gz

点击(此处)折叠或打开

Step 4: 复制解压文件到运行目录
[mongo@mysql ~]$ pwd
/home/mongo
[mongo@mysql ~]$ mv mongodb-linux-x86_64-3.2.1 mongo
[mongo@mysql ~]$ ll
total 55108
drwxrwxr-x. 3 mongo mongo     4096 Jan 11 13:05 mongo
-rw-r-----. 1 mongo mongo 56419937 Jan 21  2016 mongodb-linux-x86_64-3.2.1.tgz

[mongo@mysql ~]$ 
Step 5: 设置环境变量
[mongo@mysql ~]$ vi .bash_profile 
PATH=$PATH:$HOME/bin:/home/mongo/mongo/bin
export PATH

Step 6: 创建数据目录
# mkdir -p /data/mongodata

二、启动及验证mongodb
###启动mongo
# mongod --dbpath /home/mongo/mongo/data


###以下内容为启动后输出的相关信息
[mongo@mysql ~]$ mongod -dbpath /home/mongo/mongo/data/

###停止mongo,直接使用ctrl + c
f^C2016-01-11T13:09:46.734+0800 I CONTROL  [signalProcessingThread] got signal 2 (Interrupt), will terminate after current cmd ends

###修复启动过程中的两个警告,关于使用root用户启动mongo的警告先忽略
# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

###再次重启,后置于后台进程,
# mongod --dbpath /home/mongo/mongo/data &

###查看启动后的进程
# ps -ef|grep mongo


###使用mongo连接到mongod
# mongo
MongoDB shell version: 3.2.1

RUNNING

  For command line options invoke:

    $ ./mongod --help

  To run a single server database:

    $ mkdir /data/db
    $ ./mongod
    $
    $ # The mongo javascript shell connects to localhost and test database by default:
    $ ./mongo
    > help

DRIVERS

  Client drivers for most programming languages are available at mongodb.org.  Use the
  shell ("mongo") for administrative tasks.
