CentOS系统下MongoDB安装及配置教程
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
vi /etc/yum.repos.d/10gen.repo
[10gen]
name=10gen Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
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
$ 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:
[root@vm ~]# yum info mongo-10gen-server

[root@vm ~]#
二、安装MongoDB的服务器端和客户端工具
[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
[root@vm ~]# yum install mongo-10gen
[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
代码如下:
[root@vm ~]# cat /etc/mongod.conf
# mongo.conf
#where to log
logpath=/var/log/mongo/mongod.log
logappend=true #以追加方式写入日志
# fork and run in background
fork = true
#port = 27017 #端口
dbpath=/var/lib/mongo #数据库文件保存位置
# Enables periodic logging of CPU utilization and I/O wait

#nocursors = true

#nohints = true
# 禁用http界面,默认为localhost:28017

#nohttpinterface = true
# 关闭服务器端脚本,这将极大的限制功能
# Turns off server-side scripting. This will result in greatly limited
# functionality
#noscripting = true
# 关闭扫描表,任何查询将会是扫描失败
# Turns off table scans. Any query that would do a table scan fails.
#notablescan = true
# 关闭数据文件预分配
# Disable data file preallocation.
#noprealloc = true
# 为新数据库指定.ns文件的大小,单位:MB
# Specify .ns file size for new databases.
# nssize = <size>
# Accout token for Mongo monitoring server.
#mms-token = <token>
# mongo监控服务器的名称
# Server name for Mongo monitoring server.
#mms-name = <server-name>
# mongo监控服务器的ping 间隔
# Ping interval for Mongo monitoring server.
#mms-interval = <seconds>
# Replication Options 复制选项
# in replicated mongo databases, specify here whether this is a slave or master 在复制中,指定当前是从属关系
