本篇文章主要对如何在Linux下安装与配置 MongoDB 进行介绍。

# 环境准备 #

**Linux版本：**CentOS 7.2

MongoDB压缩包下载地址：

[https://www.mongodb.com/download-center\#atlas][https_www.mongodb.com_download-center_atlas]

选择你所需的版本：

![70][]

我使用的是 [mongodb-linux-x86\_64-rhel70-4.0.2.tgz][mongodb-linux-x86_64-rhel70-4.0.2.tgz] ，其下载地址为：

[https://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-rhel70-4.0.2.tgz][mongodb-linux-x86_64-rhel70-4.0.2.tgz]

可以使用如下命令直接将压缩包下载至 Linux 服务器，下载过程中可能会报 Unable to establish SSL connection 错误：

[root@hadoop40 soft]# wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.0.2.tgz
    --2018-10-08 16:50:39-- https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.0.2.tgz
    Resolving fastdl.mongodb.org (fastdl.mongodb.org)... 13.35.8.98, 13.35.8.53, 13.35.8.95, ...
    Connecting to fastdl.mongodb.org (fastdl.mongodb.org)|13.35.8.98|:443... connected.
    Unable to establish SSL connection.

将下载地址改为 [http://fastdl.mongodb.org/linux/mongodb-linux-x86\_64-rhel70-4.0.2.tgz][http_fastdl.mongodb.org_linux_mongodb-linux-x86_64-rhel70-4.0.2.tgz] ，即可下载成功。

[root@hadoop40 soft]# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.0.2.tgz
    --2018-10-08 16:53:31-- http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.0.2.tgz

当然，你也可以先下载好MongoDB压缩包，然后使用WinSCP等远程连接工具将其上传到服务器上。

# 安装MongoDB #

# 将下载好的 MongoDB 压缩包解压到 /usr/local/
    [root@hadoop40 soft]# tar zxvf mongodb-linux-x86_64-rhel70-4.0.2.tgz -C /usr/local/

    # 由于 mongodb-linux-x86_64-rhel70-4.0.2 目录名称比较长，将其重命名为 mongodb-4.0.2
    [root@hadoop40 soft]# mv /usr/local/mongodb-linux-x86_64-rhel70-4.0.2/ /usr/local/mongodb-4.0.2/

# 配置环境变量(root权限) #

[root@hadoop40 soft]# vim /etc/profile
    [root@hadoop40 soft]# source /etc/profile

在 /etc/profile 配置文件中添加 MongoDB 环境变量，内容如下：

PATH=$PATH:/usr/local/mongodb-4.0.2/bin

# 启动MongoDB #

接下来，创建 data 和 log 两个文件夹分别用来存放 MongoDB 的数据和日志文件。

[root@hadoop40 soft]# mkdir /usr/local/mongodb-4.0.2/data
    [root@hadoop40 soft]# mkdir /usr/local/mongodb-4.0.2/log

然后，执行如下命令使用指定的配置来启动 MongoDB：

[root@hadoop40 soft]# mongod --dbpath /usr/local/mongodb-4.0.2/data/ --logpath /usr/local/mongodb-4.0.2/log/mongodb.log --fork --bind_ip 172.16.250.240 --port 27017
    2018-10-09T10:19:47.483+0800 I CONTROL [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
    about to fork child process, waiting until server is ready for connections.
    forked process: 3093
    child process started successfully, parent exiting

你也可以将以上启动配置写到一个配置文件中 mongodb.conf，内容如下：

dbpath=/usr/local/mongodb-4.0.2/data
    logpath=/usr/local/mongodb-4.0.2/log/mongodb.log
    fork=true
    logappend=true
    bind_ip=172.16.250.240
    port=27017

并使用如下命令使用 mongodb.conf 配置文件中的配置来启动 MongoDB：

[root@hadoop40 soft]# mongod -config /usr/local/mongodb-4.0.2/mongodb.conf
    2018-10-09T10:32:54.788+0800 I CONTROL [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
    about to fork child process, waiting until server is ready for connections.
    forked process: 3316
    child process started successfully, parent exiting

# MongoDB连接测试 #

首先执行 **ps -ef|grep mongo** 命令查看MongoDB进程是否已经启动：

[root@hadoop40 soft]# ps -ef|grep mongo
    root 3316 1 1 10:19 ? 00:00:01 mongod --dbpath /usr/local/mongodb-4.0.2/data/ --logpath /usr/local/mongodb-4.0.2/log/mongodb.log --fork --bind_ip 172.16.250.240 --port 27017
    root 3142 24012 0 10:21 pts/0 00:00:00 grep --color=auto mongo

然后执行如下命令进行连接：

[root@hadoop40 soft]# mongo -host 172.16.250.240 -port 27017
    MongoDB shell version v4.0.2
    connecting to: mongodb://172.16.250.240:27017/
    MongoDB server version: 4.0.2
    Server has startup warnings:

    Enable MongoDB's free cloud-based monitoring service, which will then receive and display
    metrics about your deployment (disk utilization, CPU, operation statistics, etc).
    The monitoring data will be available on a MongoDB website with a unique URL accessible to you
    and anyone you share the URL with. MongoDB may use this information to make product
    improvements and to suggest MongoDB products and deployment options to you.
    To enable free monitoring, run the following command: db.enableFreeMonitoring()
    To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
    ---

关闭MongoDB服务使用如下命令：

[root@hadoop40 mongodb-4.0.2]# mongod --shutdown --dbpath /usr/local/mongodb-4.0.2/data
    2018-11-13T14:47:05.932+0800 I CONTROL  [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
    killing process with pid: 3509
