使用docker安装Mongo
1、拉取镜像
注：需要科学上网
docker pull mongo
[root@localhost ~]# docker pull mongo
Using default tag: latest
latest: Pulling from library/mongo
846c0b181fff: Pull complete

Status: Downloaded newer image for mongo:latest
docker.io/library/mongo:latest
查看镜像
docker images
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mongo latest 0850fead9327 3 weeks ago 700MB2、运行容器
2.1、创建文件夹
将容器中mongo文件同步至宿主机中
mkdir -p /data/mongo
[root@localhost ~]# mkdir -p /data/mongo2.2、运行容器
docker run --restart=always --name mongo -v /data/mongo:/data/db -p 27017:27017 -d mongo --auth
[root@localhost ~]# docker run --restart=always --name mongo -v /data/mongo:/data/db -p 27017:27017 -d mongo --auth
584b06bef760661b6101d5e601eae81087314721b8c3380ae303eb52cb7dc8a8
2.3、查看运行的容器
docker ps
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
584b06bef760 mongo "docker-entrypoint.s…" 10 seconds ago Up 9 seconds 0.0.0.0:27017->27017/tcp, :::27017->27017/tcp mongo
3、进入容器且设置
3.1、进入容器
docker exec -it mongo bash
[root@localhost ~]# docker exec -it mongo bash
root@584b06bef760:/#3.2、打开mongo shell
mongosh
root@584b06bef760:# mongosh
Current Mongosh Log ID: 63b3fd044545c473a3a29c24
Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.6.1
Using MongoDB: 6.0.3
Using Mongosh: 1.6.1For mongosh info see: https://docs.mongodb.com/mongodb-shell/To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
You can opt-out by running the disableTelemetry() command.test>
3.3、创建用户设置密码
use admin
db.createUser({user:"tracy",pwd:"123456",roles:[{role:'root',db:'admin'}]})
test> use admin
switched to db admin
admin> db.createUser({user:"tracy",pwd:"123456",roles:[{role:'root',db:'admin'}]})
{ ok: 1 }
3.4、登录数据库
db.auth('tracy','123456')
admin> db.auth('tracy','123456')
{ ok: 1 }
3.5、退出mongo shell
exit
admin> exit;
root@584b06bef760:/#3.4、修改配置文件
3.4.1、安装vim
apt-get update
apt-get install -y vim

Processing triggers for libc-bin (2.31-0ubuntu9.9) ...
注：如果直接执行apt-get install -y vim，出现如下错误，则先更新配置国内镜像（即先执行命令apt-get update），如下所示
root@584b06bef760:/# apt-get install -y vim
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package vim
3.4.2、修改配置文件
vim /etc/mongod.conf.orig
将bindIp由原来的127.0.0.1改为0.0.0.0，如下图所示
按Esc退出编辑，输入:wq保存退出。
3.5、退出容器并重启
docker restart mongo
root@584b06bef760:/# exit
exit
[root@localhost ~]# docker restart mongo
mongo
4、开放端囗
如需外部访问mongo，则需要开放端囗
4.1、开放端囗
firewall-cmd --zone=public --add-port=27017/tcp --permanent
[root@localhost ~]# firewall-cmd --zone=public --add-port=27017/tcp --permanent
success
4.2、重启防火墙
firewall-cmd --reload
[root@localhost ~]# firewall-cmd --reload
success
4.3、查看开放的端囗
firewall-cmd --list-ports
[root@localhost ~]# firewall-cmd --list-ports
7878/tcp 8545/tcp 8546/tcp 18545/tcp 40303/tcp 27017/tcp
5、外部连接centos7中的mongo
5.1、打开Navicat，新建MongoDB连接
5.2、设置连接参数
5.3、测试连接结果
6、常用命令
6.1、查看所有集合
show collections
6.2、查看集合数据
db.集合名称.find().pretty()
