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]
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

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

[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()
{ "_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") }
