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=0

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
