一、准备工作: 运行yum命令查看MongoDB的包信息 [[email protected] ~]# 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 [[email protected] ~]# yum info mongo-10gen-server ****(省略多行不重要的信息)********* Available Packages Name : mongo-10gen-server Arch : x86_64 Version : 1.8.2 Release : mongodb_1 Size : 4.7 M Repo : 10gen 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. [[email protected] ~]# 查看客户端工具的信息 [[email protected] ~]# yum info mongo-10gen Loaded plugins: fastestmirror **(省略多行不重要的信息)** Installed Packages Name : mongo-10gen Arch : x86_64 Version : 1.8.2 Release : mongodb_1 Size : 55 M Repo : 10gen Summary : mongo client shell and tools URL : http://www.mongodb.org License : AGPL 3.0 Description: Mongo (from "huMONGOus") is a schema-free document-oriented : database.

[[email protected] ~]# 二、安装MongoDB的服务器端和客户端工具 1.安装服务器端: [[email protected] ~]# yum install mongo-10gen-server [[email protected] ~]# 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: [[email protected] ~]# yum install mongo-10gen 3.检查 [[email protected] ~]# /etc/init.d/mongod Usage: /etc/init.d/mongod {start|stop|status|restart|reload|force-reload|condrestart} [[email protected] ~]# /etc/init.d/mongod status mongod (pid 1341) is running... [[email protected] ~]# 说明安后服务器端已经在运行了 4.服务器配置: /etc/mongod.conf [[email protected] ~]# 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 #启用定期记录CPU利用率和 I/O 等待 #cpu = true # Turn on/off security.

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 [[email protected] ~]# 以上是默认的配置文件中的一些参数,更多参数可以用 mongod -h 命令来查看 [[email protected] ~]# mongod -h Allowed options: General options: -h [ --help ] show this usage information --version show version information -f [ --config ] arg configuration file specifying additional options 指定启动配置文件路径 -v [ --verbose ] be more verbose (include multiple times for more verbosity e.g. -vvvvv) --quiet quieter output --port arg specify port number 端口 --bind_ip arg comma separated list of ip addresses to listen on - all local ips by default 绑定ip,可以多个 --maxConns arg max number of simultaneous connections 最大并发连接数 --logpath arg log file to send write to instead of stdout - has to be a file, not directory 日志文件路径 --logappend append to logpath instead of over-writing 日志写入方式 --pidfilepath arg full path to pidfile (if not set, no pidfile is created) pid文件路径 --keyFile arg private key for cluster authentication (only for replica sets)集群认证私钥,仅适用于副本集 --unixSocketPrefix arg alternative directory for UNIX domain sockets (defaults to /tmp)替代目录 --fork fork server process --auth run with security 使用认证方式运行 --cpu periodically show cpu and iowait utilization 定期显示的CPU和IO等待利用率 --dbpath arg directory for datafiles 数据库文件路径 --diaglog arg 0=off 1=W 2=R 3=both 7=W+some reads oplog记录等级 --directoryperdb each database will be stored in a separate directory 每个数据库存储到单独目录 --journal enable journaling 记录日志,建议开启,在异常宕机时可以恢复一些数据 --journalOptions arg journal diagnostic options --ipv6 enable IPv6 support (disabled by default) --jsonp allow JSONP access via http (has security implications)允许JSONP通过http访问,该方式存在安全隐患 --noauth run without security 不带安全认证的方式 --nohttpinterface disable http interface 禁用http接口 --noprealloc disable data file preallocation - will often hurt performance 禁用数据文件的预分配,往往会损害性能 --noscripting disable scripting engine 禁用脚本引擎 --notablescan do not allow table scans 不允许表扫描 --nounixsocket disable listening on unix sockets禁止unix sockets监听 --nssize arg (=16) .ns file size (in MB) for new databases 为新数据设置.ns文件的大小 --objcheck inspect client data for validity on receipt 检查在收到客户端的数据的有效性 --profile arg 0=off 1=slow, 2=all --quota limits each database to a certain number of files (8 default)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 --quotaFiles arg number of files allower per db, requires --quota --rest turn on simple rest api 开启rest api --repair run repair on all dbs 修复所有数据库 --repairpath arg root directory for repair files - defaults to dbpath修复文件的根目录,默 认为dbpath指定的目录 --slowms arg (=100) value of slow for profile and console log --smallfiles use a smaller default file size --syncdelay arg (=60) seconds between disk syncs (0=never, but not recommended)与硬盘同步数据的时间,默认60秒,0表示不同步到硬盘(不建议) --sysinfo print some diagnostic system information打印一些诊断系统信息 --upgrade upgrade db if needed 如果必要,将数据库文件升级到新的格式 (<=1.0到1.1+升级时所需的) Replication options: 复制选项 --fastsync indicate that this instance is starting from a dbpath snapshot of the repl peer 从一个dbpath快照开始同步 --autoresync automatically resync if slave data is stale 自动同步,如果从机的数据不是新的 自动同步 --oplogSize arg size limit (in MB) for op log oplog的大小 Master/slave options: 主/从配置选项 --master master mode 主模式 --slave slave mode 从属模式 --source arg when slave: specify master as <server:port>从属服务器上指定主服务器地址 --only arg when slave: specify a single database to replicate从属服务器上指定要复制的 数据库 --slavedelay arg specify delay (in seconds) to be used when applying master ops to slave 指定从主服务器上同步数据的时间间隔 单位秒 Replica set options: 副本集选项 --replSet arg arg is <setname>[/<optionalseedhostlist>] 参数:<名称>[<种子主机列表>] Sharding options: 分片设置选项 --configsvr declare this is a config db of a cluster; default port 27019; default dir /data/configdb 声明这是一个集群的配置数据库, 默认的端口是27019 默认的路径是/data/configdb --shardsvr declare this is a shard db of a cluster; default port 27018 声明这是集群的一个分片数据库,默认端口为27018 --noMoveParanoia turn off paranoid saving of data for moveChunk. this is on by default for now, but default will switch 关闭偏着保存大块数据。现在它是默认的,但是会变换 [[email protected] ~]#
