MongoDB的使用

发布于 2022-01-08 16:02 阅读 1033

使用docker-compose部署mongo和mongo-express

docker-compose.yml

version: '3.8'

# 使用外部网络
# docker network create server_web-network
networks:
  server_web-network:
    external: true

services:
  docker-mongo:
    image: mongo:5.0.5
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: 123456
    ports:
      - 27017:27017 #为了在宿主机使用vs code连接mongo
    volumes:
      - ./data:/data/db
    networks:
      - server_web-network

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: 123456
      ME_CONFIG_MONGODB_URL: mongodb://root:123456@docker-mongo:27017/
    networks:
      - server_web-network

启动服务

docker-compose up -d

访问mongo-express

http://localhost:8081/

php extension and library

虽然可以单独使用扩展,但强烈建议用户一起使用扩展和库。该库提供了与其他 MongoDB 语言驱动程序一致的高级 API。

extension

# Dockerfile
...
RUN pecl install mongodb-1.12.0 \
    && docker-php-ext-enable mongodb
...

library

composer require mongodb/mongodb

php demo

<?php
require_once __DIR__ . '/../../vendor/autoload.php';

$collection = (new MongoDB\Client('mongodb://root:123456@docker-mongo/'))->images->shop1;

$document=[
    'content' => 'uuuu2',
    'uri'=>'ss.jpg',
    'create_time' => time(),
    'update_time' => 0,
];
$updateResult = $collection->updateOne(
    ['_id' => md5(11)],
    ['$set' => $document],
    ['upsert' => true]
);

printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
printf("Upserted %d document(s)\n", $updateResult->getUpsertedCount());

$upsertedDocument = $collection->findOne([
    '_id' => $updateResult->getUpsertedId(),
]);

var_dump($upsertedDocument);

//$document = $collection->findOne(['_id' => md5(11)]);
//
//var_dump($document->content);
//echo json_encode($document, JSON_UNESCAPED_UNICODE);

备份/恢复

mongodump 和mongorestore 是mongodb自带的工具,如果本地没有安装mongodb,可以单独下载 https://www.mongodb.com/try/download/database-tools

备份

docker exec -it {容器id} /bin/sh
cd /data/db
mkdir dump
mongodump -d {库名} -o ./dump -u root -p 123456 --authenticationDatabase admin

恢复

mongorestore -h 127.0.0.1:27017 -u root -p 123456 --authenticationDatabase admin --dir=/data/dump
