前言

本文将介绍在docker环境下如何搭建常用的后端开发环境。

---

一、环境准备与Docker基础

1.1 CentOS 7.6基础配置

1.1.1 MobaXterm远程连接

1.1.2 更新yum

yum update -y

1.2 Docker与Docker Compose安装

1.2.1 docker 安装

yum install docker -y

1.2.2 docker-compose安装

yum install docker-compose -y

二、单容器创建

2.1 Mysql容器

2.1.1 数据目录映射

• /root/finance/mysql-test/data
• /root/finance/mysql-test/conf
• /root/finance/mysql-test/logs

2.1.2 创建mysql容器

docker run -it --name mysql-test -p 7001:3306 
-v /root/finance/mysql-test/data:/var/lib/mysql
-v /root/finance/mysql-test/conf:/etc/mysql/conf.d
-v /root/finance/mysql-test/logs:/etc/log/mysql
-e MYSQL_ROOT_PASSWORD=abc123456789 
-d  mysql:8.0.20

2.2 MongoDB容器

2.2.1 数据目录映射

• /root/finance/mongo-test/mongod.conf
• /root/finance/mongo-test/data/db
• /root/finance/mongo-test/data/db

2.2.2 mongod.conf 文件配置

net:port: 27017bindIp: "0.0.0.0"
storage:dbPath: "/data/db"
security:authorization: enabled

2.2.3 创建mongodb容器

docker run -it --name mongo-test -p 7003:27017 
-v /root/finance/mongo-test:/etc/mongo 
-v /root/finance/mongo-test/data/db:/data/db 
-v /root/finance/mongo-test/mongod.conf:/etc/mongo/mongod.conf  
-e MONGO_INITDB_ROOT_USERNAME=admin 
-e MONGO_INITDB_ROOT_PASSWORD=gw0420- 
-d mongo:latest 
--config /etc/mongo/mongod.conf

2.3 Redis容器

2.3.1 数据目录映射

• /root/finance/redis-test/conf

2.3.2 redis.conf 文件配置

bind 0.0.0.0
protected-mode yes
port 6379
tcp-backlog 511
timeout 0
tcp-keepalive 0
loglevel notice
logfile ""
databases 4
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
dir ./
requirepass abc123456

2.3.3 创建redis容器

docker run -it --name some-redis -p 7002:6379 
-v /root/finance/redis-test/conf:/usr/local/etc/redis 
-d --restart=always redis:latest 
redis-server /usr/local/etc/redis/redis.conf

2.4 Minio容器

2.4.1 数据目录映射

• /root/finance/minio-test/data

2.4.2 创建minio容器

docker run -it --name minio-test -p 7004:9000 -p 7005:9001 
-v /root/finance/minio-test/data:/bitnami/minio/data 
-e MINIO_ROOT_USER=root 
-e MINIO_ROOT_PASSWORD=csy0420- 
-d bitnami/minio:latest

三、Docker Compose容器编排

3.1 编写docker-compose.yml文件

version: '2.1'
services:app:build: ./ container_name: mis-api-testports:- 7700:7700depends_on:- mysql- redis- mongo- miniomysql:image: mysql:8.0.20container_name: mis-mysqlports:- 7001:3306environment: MYSQL_ROOT_PASSWORD: abc123456volumes:- /root/finance/mysql-test/data:/var/lib/mysql - /root/finance/mysql-test/conf:/etc/mysql/conf.d- /root/finance/mysql-test/logs:/etc/log/mysqlredis:image: redis:6.0.10container_name: mis-redisports:- 7002:6379volumes:- /root/finance/redis-test/conf:/usr/local/etc/rediscommand: redis-server /usr/local/etc/redis/redis.confmongo:image: mongo:4.4.7container_name: mis-mongoports:- 7003:27017volumes:- /root/finance/mongo-test/mongod.conf:/etc/mongo/mongod.conf - /root/finance/mongo-test/data/db:/data/db- /root/finance/mongo-test/data/db:/var/log/mongodbenvironment:ME_CONFIG_MONGODB_ADMINUSERNAME: rootME_CONFIG_MONGODB_ADMINPASSWORD: abc123456command: --config /etc/mongo/mongod.confminio:image: bitnami/minio:latestcontainer_name: mis-minioports:- 7004:9001- 7005:9000volumes:- /root/finance/minio-test/data:/bitnami/minio/dataenvironment:- MINIO_ROOT_USER=root- MINIO_ROOT_PASSWORD=abc123456

3.2 一键启动与停止

• 启动服务：docker compose up -d
• 查看日志：docker compose logs -f
• 停止服务：docker compose down

3.3 命令演示
