为了学习先单机安装，尝试一下mongodb的魅力。当前最新版本为3.0，目前我们以2.6.8版本为例，后续再专门了解一下mongodb 3.0。

下载地址：[http://www.mongodb.org/downloads][http_www.mongodb.org_downloads]

一、下载安装、配置

下载：wget http://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-2.6.8.tgz（也可以通过下载源码编译）  
解压：tar-zxvf mongodb-linux-x86\_64-2.6.8.tgz  
重命名：mv mongodb-linux-x86\_64-2.6.8 mongodb-2.6.8  
创建数据和日志存储文件夹：  
cd mongodb-2.6.8  
mkdir  data  
mkdir  logs

touch ./logs/mongodb.log

安装目录bin下文件：

-rwxr-xr-x. 1 mongo mongo 23377044 Feb 24 10:21 bsondump
    -rwxr-xr-x. 1 mongo mongo 11658496 Feb 24 10:21 mongo
    -rwxr-xr-x. 1 mongo mongo 23565076 Feb 24 10:21 mongod
    -rwxr-xr-x. 1 mongo mongo 23448820 Feb 24 10:20 mongodump
    -rwxr-xr-x. 1 mongo mongo 23396212 Feb 24 10:20 mongoexport
    -rwxr-xr-x. 1 mongo mongo 23441152 Feb 24 10:21 mongofiles
    -rwxr-xr-x. 1 mongo mongo 23416180 Feb 24 10:20 mongoimport
    -rwxr-xr-x. 1 mongo mongo 23387380 Feb 24 10:21 mongooplog
    -rwxr-xr-x. 1 mongo mongo 23194084 Feb 24 10:21 mongoperf
    -rwxr-xr-x. 1 mongo mongo 23487572 Feb 24 10:20 mongorestore
    -rwxr-xr-x. 1 mongo mongo 18136944 Feb 24 10:21 mongos
    -rwxr-xr-x. 1 mongo mongo 23437780 Feb 24 10:21 mongostat
    -rwxr-xr-x. 1 mongo mongo 23380116 Feb 24 10:21 mongotop

二、启动、关闭

1、正常启动

启动mongodb(如果采用安全认证模式，需要加上--auth选项，--fork以创建子进程的方式运行)：

./bin/mongod --dbpath=/home/mongo/mongodb-2.6.8/data --logpath=/home/mongo/mongodb-2.6.8/logs/mongodb.log --logappend &

默认启动27017端口。

2、以修复模式启动  
mongod --repair  
以修复模式启动数据库。

3、终止服务器进程

>use admin;

>db.shutdownServer();

终止数据库服务器进程

也可以：ps -ef |grep mongod   通过kill -9 pid 关闭

mongod命令说明：

三、客户端命令测试

使用客户端命令连接mongodb：

> mongo (可以指定IP、端口、及数据库等)

> use test\_db; //创建数据库

> db.createCollection("test"); //创建表

> db.test\_db.save(\{"name":"jetty","age":25\}); //添加数据

> db.test\_db.test.find(); //查询数据

\{ "\_id" : ObjectId("5503f6e856d0297944b9c8f0"), "name" : "jetty", "age" : 25 \}
