虚拟机客户端vmware player

linux版本：CentOS Linux release 7.4.1708 (Core)

CentOS安装类型：Basic Web Server

参照官网最新文档描述安装

https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/

一、安装

1、配置下载mongodb的仓库文件

vi /etc/yum.repos.d/mongodb-org-4.0.repo

填充内容

[mongodb-org-4.0]name=MongoDB Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/gpgcheck=1enabled=1gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

2、下载安装包到/home/mongodb-rpm-package下

yum install --downloaddir=/home/mongodb-rpm-package/ --downloadonly mongodb-org

3、安装

rpm -ivh /home/mongodb-rpm-package/*

4、启动mongo

systemctl start mongod.service

5、登陆，查询

可以看到，mongodb默认有三个db，分别为admin，config，local

到此，通过默认安装方式已经完成，

二、修改配置

通过默认安装，mongodb不允许远程登陆，也没有访问控制，默认mongodb的日志和db路径分别被放到了/var/log/mongodb/和/var/lib/mongo下（如果需要，则自定义日志和db路径）

1、停止mongod

systemctl stop mongod.service

2、配置访问控制

Security – Role-Based Access Control中对访问控制有明确描述，我们通过在配置文件中添加security.authorization参数进行访问控制，该值默认为disabled

vim /etc/mongod.conf

添加如下配置

3、配置mongodb日志和db路径

新建mongodb日志和db路径（PS:最初将db和log放入/home/mongodb下，但使用开机服务一直都无法启动mongodb，建议自定义log和db时不要使用上述路径）

mkdir -p /home/mongodb-home/logmkdir -p /home/mongodb-home/dbchown -R mongod:mongod /home/mongodb-home

vim /etc/mongod.conf

修改配置

systemLog.path修改为/home/mongodb-home/mongod.log

storage.dbPath修改为/home/mongodb-home/db

移动数据库

mv /var/lib/mongo/* /home/mongodb-home/db/

5、配置远程访问

vim /etc/mongod.conf

bindIp修改为0.0.0.0，即允许所有的ip地址访问

5、其他配置修改

如需其他配置修改，可参考该官方文档

https://docs.mongodb.com/manual/reference/configuration-options/

6、启动mongodb实例

systemctl start mongod.service

正常登陆，但此时show dbs已经不能查询出数据库

PS：

如果没有使用默认的mongodb安装路径或者端口，并且SELinux是enforceing模式，则需要配置下SELinux，否则将不能够正常访问mongodb，最简单的方式就是配置/etc/selinux/config中SELINUX=disabled

本例中虚拟机安装完成之后，该模式已经为disabled，所以并未影响使用

三、初始化超级用户

1、可以通过mongo登陆后，执行如下命令

use admindb.createUser(         {                 user: "root",                 pwd: "mongo",                 roles: [ { role: "root", db: "admin" } ]   } )

2、将以上命令放入js文件执行,如js名称为initUser.js

cat ./initUser.js | mongo --shell

3、也可以直接使用mongo 文件名执行js脚本

4、测试（登陆并查询数据库）

mongo -u root -p mongo

[root@localhost work]# mongo -u root -p mongoMongoDB shell version v4.0.6connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodbImplicit session: session { "id" : UUID("1fcc117d-5c26-448d-9363-ad1bcadf3e93") }MongoDB server version: 4.0.6Server has startup warnings: 2019-02-24T09:37:46.920+0800 I CONTROL  [initandlisten] 2019-02-24T09:37:46.920+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.2019-02-24T09:37:46.920+0800 I CONTROL  [initandlisten] **        We suggest setting it to 'never'2019-02-24T09:37:46.921+0800 I CONTROL  [initandlisten] 2019-02-24T09:37:46.921+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.2019-02-24T09:37:46.921+0800 I CONTROL  [initandlisten] **        We suggest setting it to 'never'2019-02-24T09:37:46.921+0800 I CONTROL  [initandlisten] ---Enable MongoDB's free cloud-based monitoring service, which will then receive and displaymetrics 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 youand anyone you share the URL with.

正常

PS:

1、需要注意的是，一旦设置了访问控制，即将配置文件中security.authorization设置为enabled，则mongo会提供一个localhost exception以便用于创建第一个用户，当然，也可以在设置访问控制前新建用户，但是必须要有一个具有超级权限的用户

2、Security -- Authentication中有一段描述需要关注下

3、root角色具有最大权限，一下为内置用户角色

https://docs.mongodb.com/manual/reference/built-in-roles/

四、脚本安装

将以上步骤整合成shell脚本安装mongodb

提前获取到mongod.conf，将所需参数进行修改，拷贝到默认路径/etc下，mongodb安装时会根据该配置配置数据库，日志等信息

mongod.conf

# mongod.conf# for documentation of all options, see:#   http://docs.mongodb.org/manual/reference/configuration-options/# where to write logging data.systemLog:  destination: file  logAppend: true  path: /home/mongodb-home/log/mongod.log# Where and how to store data.storage:  dbPath: /home/mongodb-home/db  journal:    enabled: true#  engine:#  mmapv1:#  wiredTiger:# how the process runsprocessManagement:  fork: true  # fork and run in background  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile  timeZoneInfo: /usr/share/zoneinfo# network interfacesnet:  port: 27017  bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.#security:#operationProfiling:#replication:#sharding:## Enterprise-Only Options#auditLog:#snmp:

五、卸载mongo

mongodb的卸载很简单

1、停止服务

2、执行如下卸载命令

sudo yum erase $(rpm -qa | grep mongodb-org)

3、删除日志和db文件，对应/etc/mongod.conf中的systemLog.path和storage.dbPath路径
