1.下载安装包

首先需要从mongodb官网https://www.mongodb.com/download-center#production下载对应的安装包mongodb-linux-x86_64-3.4.9.tgz；

或者直接通过命令下载：

    wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.4.9.tgz

2.解压缩安装包

首先上传mongodb-linux-x86_64-3.4.9.tgz至Centos虚拟机，解压缩安装包至相应目录：

    [hadoop@server ~]$ cd /opt/softwares/    
    [hadoop@server softwares]$ tar -xzvf mongodb-linux-x86_64-3.4.9.tgz -C /opt/modules/

为方便操作，重命名解压后目录为mongodb:

    [hadoop@server softwares]$ cd /opt/modules/
    [hadoop@server modules]$ mv mongodb-linux-x86_64-3.4.9 mongodb
    [hadoop@server modules]$ cd mongodb/
    [hadoop@server mongodb]$ ls
    bin  GNU-AGPL-3.0  MPL-2  README  THIRD-PARTY-NOTICES

个人习惯将服务的数据存放在/opt/data目录下，需要创建db目录用于存放数据库文件，logs目录存放日志文件:

    [hadoop@server mongodb]$ mkdir -p /opt/data/mongodb/data
    [hadoop@server mongodb]$ mkdir -p /opt/data/mongodb/data/db
    [hadoop@server mongodb]$ mkdir -p /opt/data/mongodb/data/logs
    [hadoop@server mongodb]$ touch /opt/data/mongodb/data/logs/mogodb.log

4.创建MongoDB配置文件mongodb.conf

mongodb.conf主要配置MongoDB的监听端口，数据库目录，日志存放位置，日志输出方式以及是否开启后台运行等：

    [hadoop@server data]$ cd /opt/data/mongodb/data/
    [hadoop@server data]$ vim mongodb.conf

具体配置信息如下：

    # 端口号
    port=27017

    # 数据库路径
    dbpath=/opt/data/mongodb/data/db

    # 日志输出文件路径
    logpath=/opt/data/mongodb/data/logs/mongodb.log

    pidfilepath=/opt/data/mongodb/data/mongo.pid

    # 设置后台运行
    fork=true

    # 日志输出方式
    logappend=true
    
    # 启动http界面，端口号为28017
    httpinterface=true

5.启动MongoDB服务

执行以下命令启动MongoDB服务：

    [hadoop@server data]$ cd /opt/modules/mongodb/ 
    [hadoop@server mongodb]$ bin/mongod --config /opt/data/mongodb/data/mongodb.conf

6.验证MongoDB服务是否启动成功

一般成功启动，打印如下信息：

    about to fork child process, waiting until server is ready for connections.
    forked process: 6234
    child process started successfully, parent exiting

另外，可以检查MongoDB是否成功监听27017端口：

    [hadoop@server mongodb]$ lsof -i:27017
    COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
    mongod  6234 hadoop    7u  IPv4  17293      0t0  TCP *:27017 (LISTEN)

查看MongoDB服务Web界面，输入以下地址:

    http://192.168.33.100:28017/

服务启动成功后，可以启动MongoDB客户端，进行交互操做：

    [hadoop@server mongodb]$ bin/mongo
    MongoDB shell version v3.4.9
    connecting to: mongodb://127.0.0.1:27017
    MongoDB server version: 3.4.9
    Welcome to the MongoDB shell.
    For interactive help, type "help".
