• 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
     * base: centos.ustc.edu.cn
     * extras: centos.ustc.edu.cn
     * updates: centos.ustc.edu.cn
    Installed Packages

                : database.
                :

                : server softwware, default configuration files, and init.d scripts.
    查看客户端安装情况 
    [root@localhost geffzhang]#  

    * base: centos.ustc.edu.cn
     * extras: centos.ustc.edu.cn
     * updates: centos.ustc.edu.cn
    Installed Packages
    Name        : mongo-10gen
    Arch        : x86_64
    Version     : 2.0.6
    Release     : mongodb_1
    Size        : 69 M
    Repo        : installed
    From 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. It features dynamic profileable queries, full indexing,
                : replication and fail-over support, efficient storage of large
                : binary data objects, and auto-sharding.
                : 
                : This package provides the mongo shell, import/export tools, and
                : other client utilities.

    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。
