1. 简介

mongoDB是非关系型数据库，存储类似json格式数据

2. docker安装

2.1 docker搭建单节点

docker run -d \

  -p 27017:27017 \
  -v /dockerdata/mongo/data:/data/db \
  -v /dockerdata/mongo/backup:/data/backup \
  -v /dockerdata/mongo/conf:/data/configdb \
  -e MONGO_INITDB_ROOT_USERNAME=root \
  -e MONGO_INITDB_ROOT_PASSWORD=aacopy.cn \
  mongo --auth

2.2 docker搭建伪集群

如果需要支持mongo的事务，需要集群模式，这里搭建一个简单的伪集群做事务测试

  • 编写配置文件
  • vim /dockerData/mongo/config/mongod.conf

docker run -d --name mongo -p 27017:27017 \
-v /dockerData/mongo/data/db:/data/db \
-v /dockerData/mongo/config/mongod.conf:/etc/mongo/mongod.conf \
mongo:4.4.5 --config /etc/mongo/mongod.conf

  • 进去容器：docker exec -it mongo /bin/bash

  • 打开mongo命令行 mongo

  • 依次执行命令

use admin
rs.initiate()
rs.conf()
exit
  • 伪集群搭建完成，可以测试事务
