Java代码
- 一、准备工作:
- 运行yum命令查看MongoDB的包信息 [root@vm ~]# yum info mongo-10gen
- (提示没有相关匹配的信息,)
- 说明你的centos系统中的yum源不包含MongoDB的相关资源,所以要在使用yum命令安装MongoDB前需要增加yum源,也就是在 /etc/yum.repos.d/目录中增加 *.repo yum源配置文件,以下分别是针对centos 64位和32位不同的系统的MongoDB yum 源配置内容:
- 我们这里就将该文件命名为:/etc/yum.repos.d/10gen.repo
- For 64-bit yum源配置:
- vi /etc/yum.repos.d/10gen.repo
- [10gen]
- name=10gen Repository
- baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
- gpgcheck=0
- For 32-bit yum源配置:
- vi /etc/yum.repos.d/10gen.repo
- [10gen]
- name=10gen Repository
- baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
- gpgcheck=0
- 根据自己的系统选择相应的配置内容
- 查看系统是32位还是64位的方法:
- $ uname -a
- 含有x86_64的那说明是64位的,例如我的centos6.0 64bit系统执行这个命令后显示:
- Linux vm.centos6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux
- 做好yum源的配置后,如果配置正确执行下面的命令便可以查询MongoDB相关的信息:
- 查看mongoDB的服务器包的信息
- [root@vm ~]# yum info mongo-10gen-server
- ****(省略多行不重要的信息)*********

- [root@vm ~]#
- 二、安装MongoDB的服务器端和客户端工具
- 1.安装服务器端:
- [root@vm ~]# yum install mongo-10gen-server
- [root@vm ~]# ls /usr/bin/mongo(tab键)
- mongo mongod mongodump mongoexport mongofiles mongoimport mongorestore mongos mongostat
- -----------------------------------------------
- 这些就是MongoDB的程序文件
- 因为mongo-10gen-server包依赖于mongo-10gen,所以安装了服务器后就不需要单独安装客户端工具包mongo-10gen了
- 2.单独安装可客户端:
- [root@vm ~]# yum install mongo-10gen
- 3.检查
- [root@vm ~]# /etc/init.d/mongod
- Usage: /etc/init.d/mongod {start|stop|status|restart|reload|force-reload|condrestart}
- [root@vm ~]# /etc/init.d/mongod status
- mongod (pid 1341) is running...
- [root@vm ~]#
- 说明安后服务器端已经在运行了
- 4.服务器配置: /etc/mongod.conf
- [root@vm ~]# cat /etc/mongod.conf
- # mongo.conf
- #where to log
