Mongodb学习笔记－－Mongodb安装

本文讲述如何通过rpm包进行安装，适用操作系统：RHEL,CentOS,Fedora

实验环境：CentOS 5.8 i386 fianl

具体步骤如下：

1）配置官方YUM源

[root@localhost ~]# vim /etc/yum.repos.d/10gen.repo

[root@localhost ~]# cat /etc/yum.repos.d/10gen.repo

[10gen] www.zzzyk.com

name=10gen Repository

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686

gpgcheck=0

enabled=1

64位机器源配置文件如下

[root@localhost ~]# vim /etc/yum.repos.d/10gen.repo

[root@localhost ~]# cat /etc/yum.repos.d/10gen.repo

[10gen]

name=10gen Repository

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64

gpgcheck=0

enabled=1

#其中，官方源中包括以下软件包

#mongo-10gen 这个包包含了最新最稳定的mongodb工具

#mongo-server-10gen 这个包包含了最新最稳定版本的mongod和mongos守护进程及相关的配置
和初始化脚本

#mongo18-10gen 这个包包含了之前发行版中的mongodb工具

#mongo18-server-10gen 这个包包含了前一个稳定版的mongod和mongos守护进程及相关的配置
和初始化脚本

2）系统更新

[root@localhost ~]# yum update

3）安装mongodb

[root@localhost ~]# yum install mongo-10gen mongo-10gen-server

看到提示说明安装成功

Installed:

mongo-10gen.i686 0:2.0.5-mongodb_1 mongo-10gen-server.i686 0:2.0.5-mongodb_1

www.zzzyk.com

4)配置mongodb

配置文件为：/etc/mongod.conf

初始化脚本为：/etc/rc.d/init.d/mongod

数据存储路径：/var/lib/mongo/

日志文件存储路径：/var/log/mongo/

守护进程运行用户为：mongod

以上均为默认值

5)Mongodb控制

加入开机启动

[root@localhost ~]# chkconfig mongod on

[root@localhost ~]# chkconfig --list | grep mongod

mongod 0:off 1:off 2:on 3:on 4:on 5:on 6:off

启动mongodb

[root@localhost ~]# service mongod start

Starting mongod: all output going to: /var/log/mongo/mongod.log

forked process: 26351

[ OK ]

停止mongodb

[root@localhost ~]# service mongod stop

Stopping mongod: [ OK ]

重启mongodb

www.zzzyk.com

[root@localhost ~]# service mongod restart

Stopping mongod: [ OK ]

Starting mongod: all output going to: /var/log/mongo/mongod.log

forked process: 26420

[ OK ]

6）简单使用

查找

[root@localhost ~]# mongo

MongoDB shell version: 2.0.5

connecting to: test

> db.test.save( { a: 1})

> db.test.find()

{ "_id" : ObjectId("4fb83ca7698712e93dad12a7"), "a" : 1 }

插入

> doc = { author:'joe', created : new Date('03/28/2009')}

{ "author" : "joe", "created" : ISODate("2009-03-27T16:00:00Z") }

> db.test.insert(doc)

> db.test.find()

{ "_id" : ObjectId("4fb83ca7698712e93dad12a7"), "a" : 1 }

{ "_id" : ObjectId("4fb83e2c698712e93dad12a8"), "author" : "joe", "created" :
ISODate("2009-03-27T16:00:00Z") }

更新

> db.test.update({author : 'joe'}, {$inc: { check: 1000 }});

> db.test.find() www.zzzyk.com

{ "_id" : ObjectId("4fb83ca7698712e93dad12a7"), "a" : 1 }

{ "_id" : ObjectId("4fb83e2c698712e93dad12a8"), "author" : "joe", "check" : 1000,
"created" : ISODate("2009-03-27T16:00:00Z") }

删除

> db.test.remove({a:1});

> db.test.find()

{ "_id" : ObjectId("4fb83e2c698712e93dad12a8"), "author" : "joe", "check" : 1000,
"created" : ISODate("2009-03-27T16:00:00Z") }
