CentOS 6 使用 yum 安装MongoDB及服务器端配置

安装MongoDB的方法有很多种,可以源代码安装,在Centos也可以用yum源安装的方法。由于MongoDB更新得比较快,我比较喜欢用yum源安装的方法。64位Centos下的安装步骤如下:

1、准备工作

运行yum命令查看MongoDB的包信息 [root@localhost~]# 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

2、vi /etc/yum.repos.d/10gen.repo,输入下面的语句:

[10gen] 

name=10gen Repository 

baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64 

gpgcheck=

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@localhost geffzhang]# yum info mongo-10gen-server

3、安装MongoDB的服务器端和客户端工具  
[root@localhost geffzhang]#  yum install mongo-10gen-server

[root@localhost geffzhang]#  yum install mongo-10gen

4、启动Mongodb

service mongod start

以后有更新了,停掉mongodb,执行yum update mongo-10gen mongo-10gen-server 即可。

5、服务器配置: /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   

directoryperdb=true

# Enables periodic logging of CPU utilization and I/O wait   

#启用定期记录CPU利用率和 I/O 等待   

#cpu = true  

# Turn on/off security.  Off is currently the default  

# 是否以安全认证方式运行,默认是不认证的非安全方式   

#noauth = true  

#auth = true  

# Verbose logging output.   

# 详细记录输出   

#verbose = true  

# Inspect all client data for validity on receipt (useful for  

# developing drivers)用于开发驱动程序时的检查客户端接收数据的有效性   

#objcheck = true  

# Enable db quota management 启用数据库配额管理,默认每个db可以有8个文件,可以用quotaFiles参数设置   

#quota = true  

# 设置oplog记录等级   

# Set oplogging level where n is   

#   0=off (default)   

#   1=W   

#   2=R   

#   3=both   

#   7=W+some reads   

#oplog = 0  

# Diagnostic/debugging option 动态调试项   

#nocursors = true  

# Ignore query hints 忽略查询提示   

#nohints = true  

# 禁用http界面,默认为localhost:28017  

# Disable the HTTP interface (Defaults to localhost:27018).这个端口号写的是错的   

#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   

#slave = true  

#source = master.example.com   

# Slave only: specify a single database to replicate   

#only = master.example.com   

# or   

#master = true  

#source = slave.example.com  

6.开启权限认证:

[root@localhost test]# vim /etc/mongodb.conf           //将auth=true前面的注释拿掉
[root@localhost test]# /etc/init.d/mongod restart      //重启生效

如果想把数据库从系统盘迁移到数据盘,只需配置dbpath为所需要路径,logpath可以配置,也可以不配置,最好也配置一下。
