docker compose部署mongodb 8.0.28

环境:
OS:Centos 7
mongodb:8.0.28

 

1.创建部署目录
mkdir -p /opt/mongodb
mkdir -p /opt/mongodb/data
mkdir -p /opt/mongodb/config
mkdir -p /opt/mongodb/log

修改外挂的日志文件目录权限
cd /opt/mongodb
chown -R 999:999 ./log
chmod 755 ./log

 

2.准备mongodb配置文件

vi /opt/mongodb/config/mongod.conf

[root@localhost conf]# more mongod.conf 
net:
  bindIp: 0.0.0.0
  maxIncomingConnections: 10000

storage:
  dbPath: "/data/db"
  engine: wiredTiger
  wiredTiger:
    engineConfig:
      cacheSizeGB: 6

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

##security:
##  authorization: enabled

 

这里将密码验证先注释掉,等后面创建了密码后再启用

 

3.准备部署文件
cd /opt/mongodb
vi docker-compose.yml

[root@host134 mongodb]# more docker-compose.yml 
version: '3.8'

services:
  mongodb:
    image: registry.cn-shenzhen.aliyuncs.com/hxlk8s/mongo:8.0.28
    container_name: mongodb
    restart: always
    ports:
      - "28001:27017"
    volumes:
      - ./data:/data/db
      - ./config/mongod.conf:/etc/mongod.conf
      - ./log:/var/log/mongodb
    environment:
      TZ: Asia/Shanghai
    command:
      - mongod
      - --config
      - /etc/mongod.conf

 

4.启动
[root@host134 mongodb]#cd /opt/mongodb
[root@host134 mongodb]#docker compose up -d

5.链接mongodb创建账号
下载客户端连接到容器mongosh
wget https://downloads.mongodb.com/compass/mongosh-2.10.0-linux-x64.tgz
tar -xvf mongosh-2.10.0-linux-x64.tgz

/soft/mongosh-2.10.0-linux-x64/bin/mongosh 192.168.1.134:28001
test>use admin
admin>db.createUser({user:"root",pwd:"hxl@123",roles:["root"]}); --创建用户
admin>db.auth("root","hxl@123"); --设置用户登陆权限，密码一定要和创建用户时输入的密码相同
admin>show users; --查看创建的用户

 

6.开启密码验证
修改配置文件
vi /opt/mongodb/config/mongod.conf

security:
  authorization: enabled

 

7.重启
cd /opt/mongodb
docker compose stop
docker compose start

 

8.再次登录

/soft/mongosh-2.10.0-linux-x64/bin/mongosh 192.168.1.134:28001
test> show dbs
MongoServerError[Unauthorized]: Command listDatabases requires authentication
use admin
test> use admin
switched to db admin
admin> db.auth("root","hxl@123");
{ ok: 1 }
admin> show dbs
admin   132.00 KiB
config   60.00 KiB
local    72.00 KiB

 

9.创建开发者账号
创建新的数据库和账号
>use admin
admin>db.createUser({user:'hxldev',pwd:'hxldev123',roles:[{role:'dbOwner',db:'mgdb_hxl'}]})
要写入一条记录才会显示库名
admin> use mgdb_hxl
switched to db mgdb_hxl
mgdb_hxl> show tables;
mgdb_hxl> db.tb_test.insert({"name": "xiaoming"})

 

10.相应的安装工具下载
