1.安装docker和docker-compose

1.1 安装docker软件
yum install -y docker

1.2 启动docker并将docker加入开机启动
systemctl start docker
systemctl enable docker

1.3 查看docker版本
docker version

1.4 安装docker-compose
安装epel源
yum install -y epel-release

安装docker-compose
yum install -y docker-compose

2.登录官网查看mongodb的版本号：

MongoDB Community Download | MongoDBDownload the Community version of MongoDB's non-relational database server from MongoDB's download center.https://www.mongodb.com/try/download/community

3.下载mongodb到个人虚拟机

服务器无法访问外网，个人虚拟机才可以访问外网
docker pull mongo:5.0.5  或者 docker pull mongo:latest

[root@mongodb mongodb-5.0.5]# docker pull mongo:5.0.5
Trying to pull repository docker.io/library/mongo ...

[root@mongodb mongodb-5.0.5]# 

4.打包镜像

docker save docker.io/mongo:3.6.23 > /root/mongo3.6.23.tar
docker save docker.io/mongo:5.0.5 > /root/mongo5.0.5.tar

将mongo5.0.5.tar文件从下载到本地，并上传到服务器

5.导入镜像：


在你的新的 Docker 实例中运行 docker load命令，并且指定 tar 镜像文件的位置。

docker load < /root/mongo5.0.5.tar

[root@localhost ~]# docker load < mongo5.0.5.tar

6、修改镜像tag(如需)


$ docker tag [镜像ID]  [镜像名称]:[镜像标签]

7、安装mongodb

7.1 在宿主机上创建mongodb存放目录,用来做持久化。

mkdir -p /opt/XXXXXX/product/docker-containers/mongodb-5.0.5
cd /opt/XXXXXX/product/docker-containers/mongodb-5.0.5
mkdir db conf logs configdb

7.2、创建、编写配置文件mongod.conf


dbPath、path不建议改动，bindIp改为0.0.0.0以方便外部连接MongoDB

参考：

[root@mongodb conf]# cat mongod.conf 
storage:
   dbPath: /var/lib/mongodb
   journal:
      enabled: true
# engine:
# wiredTiger:

systemLog:
   destination: file
   logAppend: true
   path: /var/log/mongodb/mongod.log

net:
   bindIp: 0.0.0.0
   port: 27017

processManagement:
   timeZoneInfo: /usr/share/zoneinfo
[root@mongodb conf]# 

7.3、上传mongod.conf


上传 / 复制 / 创建 到：/opt/XXXXXX/product/docker-containers/mongodb-5.0.5/conf/
该路径由自己决定，即数据卷目录由自己决定，只要成功挂载并能启动MongoDB即可
(该路径与下方的创建容器并挂载目录一致)


7.4、创建容器并挂载目录


很多新手会面临1个问题：如何选择挂载目录？不知道选择哪个数据卷目录、容器目录来挂载；
下方的docker run的-v中，":"左边为数据卷目录，右边为挂载目录

docker run --name mongodb \
-p 27017:27017 \
-v /opt/XXXXXX/product/docker-containers/mongodb-5.0.5/db:/data/db \
-v /opt/XXXXXX/product/docker-containers/mongodb-5.0.5/conf/mongod.conf:/etc/mongod.conf.orig \
-v /opt/XXXXXX/product/docker-containers/mongodb-5.0.5/logs:/var/log/mongodb \
-v /opt/XXXXXX/product/docker-containers/mongodb-5.0.5/configdb:/data/configdb \
-e MONGO_INITDB_ROOT_USERNAME=root \
-e MONGO_INITDB_ROOT_PASSWORD=<密码> \
--privileged=true \
--restart=always \
-d mongo:5.0.5

 7.5 登录数据库，验证密码，查看数据库

[root@localhost conf]# docker ps |grep mongo
bcba97cdcae8        mongo:5.0.5                                          "docker-entrypoint.s…"   21 seconds ago      Up 20 seconds       0.0.0.0:27017->27017/tcp   mongodb

7.6 创建数据库、创建集合

1. 创建数据库qyqdb
use qyqdb
（注：这里还并没有在本地创建该数据库，需要在该数据库添加集合(表)之后才算真正创建了）

2. 创建user集合(表),也是插入数据
db.user.insert({"name":"小一",age:18})
db.user.insert({"name":"小二",age:19})
db.user.insert({"name":"张三",age:20})
db.user.insert({"name":"赵四",age:21})
db.user.insert({"name":"王老五",age:22})
db.user.insert({"name":"李老六",age:23})
db.user.insert({"name":"阮小七",age:24})
db.user.insert({"name":"郑八哥",age:25})

注意：mongodb的数据和json数据一样，格式要正确

3.查看创建的数据库
> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB
qyqdb   0.000GB


4.显示当前数据集合show collections
> show collections
user

7.7 条件查询

--条件查询，查询age=18的数据
> db.user.find({"age": 18})      
{ "_id" : ObjectId("61b1bb1f5b33d3cc45039662"), "name" : "小一", "age" : 18 }

--条件查询，查询age>24的数据$gt
> db.user.find({"age": {$gt: 24}})

{ "_id" : ObjectId("61b1bb1f5b33d3cc45039664"), "name" : "张三", "age" : 20 }

--模糊查询，查询name包含‘老’字的数据/老/
> db.user.find({"name": /老/})

> db.user.find({"name": /七$/})
{ "_id" : ObjectId("61b1bb1f5b33d3cc45039668"), "name" : "阮小七", "age" : 24 }

--查询指定列(字段)的数据，如name，age
下面只查询name的字段, 注意：要查询那个字段就写该字段=1，比如{name: 1},如果只查询age字段就{age: 1},_id是自带的。
> db.user.find({},{name: 1})
{ "_id" : ObjectId("61b1bb1f5b33d3cc45039662"), "name" : "小一" }

{ "_id" : ObjectId("61b1bb205b33d3cc45039669"), "name" : "郑八哥" }

--排序查询sort，升序：1，降序：-1
--升序
> db.user.find().sort({age: 1})
