docker-compose安装mongodb

1. 配置docker-compose.yml

# 该Yaml文件改编自DockerHub中的配置文件
version: '3.8'
services:
  mongo:
    image: mongo:4.4.0 #根据需要选择自己的镜像
    restart: always
    ports:
     - 27017:27017 #对外暴露停供服务的端口，正式生产的时候理论不用暴露。
    volumes:
     - /docker/mongodb/data/db:/data/db # 挂载数据目录
     - /docker/mongodb/data/log:/var/log/mongodb  # 挂载日志目录
     - /docker/mongodb/data/config:/etc/mongo  # 挂载配置目录
    # command: --config /docker/mongodb/mongod.conf # 配置文件

2. 创建配置文件

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /data/db
  journal:
    enabled: true
  directoryPerDB: true
  engine: wiredTiger
  wiredTiger:
    engineConfig:
      cacheSizeGB: 8
      directoryForIndexes: true

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0

# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

#replication:
replication:
   oplogSizeMB: 51200
   replSetName: rs0

3. 运行mongodb

docker-compose -f docker-compose.yml up -d

4. 进入mongodb

docker exec -it mongo /bin/bash

5. 添加用户

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