MongoDB Ops Manager 部署指南

MongoDB Ops Manager（MMS）是用于监控和备份MongoDB的基础设施服务。其中监控的服务是免费的，备份的服务是需要收费的。本文以最新的4.0.1为例，介绍如何安装配置MongoDB Ops Manager服务。

1、安装并配置MongoDB服务

[[email protected] ~]# yum -y install mongodb-org.x86_64 mongodb-org-mongos.x86_64 mongodb-org-shell.x86_64 mongodb-org-tools.x86_64 mongodb-org-server.x86_64

创建MongoDB的配置文件如下：

[[email protected] ~]# vi /etc/mongod.conf
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
net:
  port: 27017
  bindIp: 0.0.0.0

启动MongoDB服务：

[[email protected] ~]# systemctl start mongod
[[email protected] ~]# systemctl status mongod
● mongod.service - MongoDB Database Server
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
   Active: active (running) since Tue 2018-08-21 11:43:23 CST; 2h 38min ago
     Docs: https://docs.mongodb.org/manual
 Main PID: 29211 (mongod)
   CGroup: /system.slice/mongod.service
           └─29211 /usr/bin/mongod -f /etc/mongod.conf

Aug 21 11:43:23 hdp04 mongod[29208]: child process started successfully, parent exiting
Aug 21 11:43:23 hdp04 systemd[1]: Started MongoDB Database Server.

2、安装MongoDB Ops Manager

[[email protected] ~]# yum -y install mongodb-mms.x86_64
[[email protected] ~]# vi /opt/mongodb/mms/conf/conf-mms.properties
#根据实际情况修改mongodb的地址
mongo.mongoUri=mongodb://127.0.0.1:27017/?maxPoolSize=150
mongo.ssl=false

安装配置完成后，启动服务，默认的端口是8080：

[[email protected] conf]# /etc/init.d/mongodb-mms start
Generating new Ops Manager private key...
Starting pre-flight checks
Successfully finished pre-flight checks

Migrate Ops Manager data
   Running migrations...[  OK  ]
Start Ops Manager server
   Instance 0 starting......................[  OK  ]
Starting pre-flight checks
Successfully finished pre-flight checks

Start Backup Daemon...[  OK  ]

[[email protected] conf]# netstat -antpl|grep 8080
tcp6       0      0 :::8080                 :::*                    LISTEN      10494/mms-app

3、配置MongoDB Ops Manager

3.1 打开Ops管理界面
通过服务ops的8080端口，即可打开web管理界面，如下图所示:

3.2 注册管理员账号

3.3 设置Web Server和Email
设置Web Server和Email，其他的默认即可，如下图所示:

3.4 设置用户认证方式
这里使用默认的application database，如下图：

3.5 备份快照设置
使用默认的设置即可，如下图：

4、配置MongoDB Ops Manager Agent

依次点击Agents->Download & Settings，会出现所有的代理信息，如图所示：

根据实际需求选择代理类型，这里使用Automation代理。环境的操作系统是Oracle Linux 7，所以点击Centos 7对应的rpm连接，弹出安装操作步骤：

安装提示，依次在各个节点安装配置，以hdp06为例，如下：

[[email protected] ~]# curl -OL http://192.168.120.99:8080/download/agent/automation/mongodb-mms-automation-agent-manager-5.4.9.5483-1.x86_64.rhel7.rpm
[[email protected] ~]# yum -y localinstall mongodb-mms-automation-agent-manager-5.4.9.5483-1.x86_64.rhel7.rpm
[[email protected] ~]# vi /etc/mongodb-mms/automation-agent.config
mmsBaseUrl=http://192.168.120.99:8080
mmsGroupId=5b7b8bf6dd601873cb8ea94d
mmsApiKey=5b7b94f0dd601873cb8eb08e7890df416e37a186bcd77e40235210b6

需要说明的是配置文件中的mmsGroupId和mmsApiKey两个选项。mmsGroupId使用弹出的代理安装手册的值，而mmsApiKey需要点击代理安装手册中的√Key Generated方可生成。编辑完配置文件后启动代理服务：

[[email protected] ~]# systemctl start mongodb-mms-automation-agent.service
[[email protected] ~]# systemctl status mongodb-mms-automation-agent.service

待所有的代理安装配置完成后，会在web管理界面看到，如下图所示：
