MongoDB及主从配置
一、Yum安装MongoDB1、准备工作
运行yum命令查看MongoDB的包信息 # 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
vi /etc/yum.repos.d/10gen.repo，输入下面的语句：
name=10gen
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
# yum info mongo-10gen-server
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
* extras: mirrors.btte.net
* updates: mirrors.btte.net
Installed Packages
Name : mongo-10gen-server
Arch : x86_64
Version : 2.2.3
Release : mongodb_1
Size : 17 M
Repo : installed
From repo : aaa
Summary : mongo server, sharding server, and support scripts
URL : http://www.mongodb.org
License : AGPL 3.0
Description : Mongo (from "huMONGOus") is a schema-free document-oriented database.
:
: This package provides the mongo server software, mongo sharding server
: softwware, default configuration files, and init.d scripts.
3、安装MongoDB的服务器端和客户端工具
# yum -y installmongo-10gen-server
# yum -y installmongo-10gen
安装好后可以查看mongd的命令
# ls /usr/sbin/mongo
mongo mongodump mongofiles mongorestoremongosniff mongotop
mongod mongoexport mongoimport mongos mongostat
4、启动Mongodb与登陆
service mongod start
# mongo
MongoDB shell version: 2.0.4
connecting to: test
> show dbs;
admin(empty)
elaindb0.203125GB
local4.013671875GB
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>
# nssize =
# Accout token for Mongo monitoring server.
#mms-token =
# mongo监控服务器的名称
# Server name for Mongo monitoring server.
#mms-name =
# mongo监控服务器的ping 间隔
# Ping interval for Mongo monitoring server.
#mms-interval =
# 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
二、MongoDB主从配置
一、mongodb主从服务器
1.172.16.1.170mongodb主服务器
2.172.16.1.171mongodb从服务器
二、主从服务器配置
1.172.16.1.170配置
# cat /etc/mongod.conf
logpath=/var/log/mongo/mongod.log
logappend=true
fork = true
dbpath=/var/lib/mongo
pidfilepath = /var/run/mongodb/mongod.pid
master = true
source = 172.16.1.171
port=27017
2.172.16.1.171配置
# cat /etc/mongod.conf
port=27017
logpath=/var/log/mongo/mongod.log
logappend=true
fork = true
dbpath=/var/lib/mongo
pidfilepath = /var/run/mongodb/mongod.pid
slave = true
source = 172.16.1.170
3.启动主从服务器mongodb
service mongod start
