mongodb安装和测试

        今天又看了看MONGODB的版本发现又变更了，这个版本发布的速度也真够快的，于是又下载了一个新的来进行安装，之前的是安装在WINDOWS下的，下了个LINUX 86版本的，按照LINUX安装和测试的官方网站教程：http://www.mongodb.org/display/DOCS/Quickstart+Unix，亲自测试了下，将安装和测试过程记录如下：

查看我的环境：

[root@localhost /]# uname -a
Linux localhost 2.6.18-194.el5PAE #1 SMP Fri Apr 2 15:37:44 EDT 2010 i686 i686 i386 GNU/Linux

[root@localhost /]# cat /etc/redhat-release 
CentOS release 5.5 (Final)

添加用户：

[root@localhost ~]# useradd mongodb 
[root@localhost ~]# passwd mongodb

Changing password for user mongodb.
New UNIX password: 
Retype new UNIX password: 
passwd: all authentication tokens updated successfully.

创建NOSQL存储目录，默认存储在/data/db下，因此预先建立好目录，并且更改目录用户所有者：

By default MongoDB will store data in /data/db, but it won't automatically create that directory. To create it, do:

[root@localhost ~]#mkdir -p /data/db/

[root@localhost /]# chown -R mongodb /data/db/

拷贝文件到用户目录：

[root@localhost ~]# mv mongodb-linux-i686-2.0.0.tgz /home/mongodb/
[root@localhost ~]# chown mongodb /home/mongodb/mongodb-linux-i686-2.0.0.tgz 

[root@localhost /]# ll /data
总计 4
drwxr-xr-x 3 mongodb root 4096 10-13 18:43 db

切换用户，解压文件：
[root@localhost ~]# su - mongodb
[mongodb@localhost ~]$ ls
mongodb-linux-i686-2.0.0.tgz

[mongodb@localhost ~]$ ll
总计 37112
drwxr-xr-x 3 mongodb mongodb      4096 09-12 00:06 mongodb-linux-i686-2.0.0
-rw-r--r-- 1 mongodb oinstall 37949452 10-12 16:41 mongodb-linux-i686-2.0.0.tgz

启动服务端进程：

[mongodb@localhost db]$ cd ~/mongodb-linux-i686-2.0.0/bin/
[mongodb@localhost bin]$ pwd
/home/mongodb/mongodb-linux-i686-2.0.0/bin
[mongodb@localhost bin]$ ./mongod
./mongod --help for help and startup options

再开一个SHELL终端，连接客户端查看服务器进程：

[mongodb@localhost ~]$ ps -ef | grep mong
root      4360  4296  0 18:32 pts/1    00:00:00 su - mongodb
mongodb   4361  4360  0 18:32 pts/1    00:00:00 -bash
mongodb   4481  4361  0 18:40 pts/1    00:00:00 ./mongod

启动客户端进程，插入一条记录和查看该记录：

[mongodb@localhost ~]$ ./mongodb-linux-i686-2.0.0/bin/mongo
MongoDB shell version: 2.0.0
connecting to: test

> db.foo.safe({a:1})
