Docker-compose封装mysql并初始化数据以及redis

约定不等于承诺〃 2023-07-25 09:20 4阅读 0赞

# 一、概述 #

现有一台服务器，需要部署mysql和redis。其中mysql容器，需要在第一次启动时，执行sql文件。

redis保持空数据即可。

关于Docker-compose的安装，请参考连接：

# 二、封装mysql #

本文使用的mysql 5.7版本，基础镜像为官方的mysql

## 目录结构 ##

./
    ├── docker-compose.yml
    └── mysql
        ├── dockerfile
        ├── init
        │   └── test.sql
        └── mysqld.cnf

docker-compose.yml

version: '3'
    services:
      mysql:
        image: mysql:1
        container_name: mysql
        build: ./mysql
        volumes:
          - /data/mysql/data:/var/lib/mysql
          - ./mysql/init:/docker-entrypoint-initdb.d/
        environment:
          - MYSQL_ROOT_PASSWORD=abcd1234
        ports:
          - "3306:3306"
        restart: always
        command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

参数解释：

image：指定服务的镜像名称或镜像ID。如果镜像在本地不存在，Compose将会尝试拉取镜像。

container\_name：容器名称，相当于docker run --name xxx，里面的--name参数。

build：指定Dockerfile所在文件夹的路径。Compose将会利用Dockerfile自动构建镜像，然后使用镜像启动服务容器。

volumes：挂载一个目录或者一个已存在的数据卷容器，相当于docker run -v xxx:xxx里面的-v参数。

environment：环境变量，相当于docker run -e xxx=xxx里面的-e参数。

ports：映射端口，相当于docker run -p xx:xx里面的-p参数。

restart：重启方式，相当于docker run --restart里面的--restart参数。

command：覆盖容器启动后默认执行的命令，相当于docker run xxx /bin/bash里面最后一段命令。

其实这个 docker-compose，等于命令：

docker run -d --restart=always --name mysql -e MYSQL_ROOT_PASSWORD=abcd1234 -p 3306:3306 -v /data/mysql/data:/var/lib/mysql -v ./mysql/init:/docker-entrypoint-initdb.d/  mysql:1 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

FROM mysql:5.7

## 生成镜像 ##

docker-compose build --no-cache

## 启动docker-compose ##

docker-compose up -d

## 测试 ##

使用mysql客户端，查看数据是否存在。

# 三、封装redis #

本文使用的redis 4.0.11版本，基础镜像为官方的redis

## 目录结构 ##

./
    ├── docker-compose.yml
    └── redis
        ├── dockerfile
        └── redis.conf

docker-compose.yml

version: '3'
    services:
      redis:
        image: redis:1
        container_name: redis
        build: ./redis
        volumes:
          - /data/redis1:/data
        ports:
          - "6379:6379"
        restart: always

dockerfile

FROM redis:4.0.10
    COPY redis.conf /usr/local/etc/redis/redis.conf
    EXPOSE 6379
    ENTRYPOINT [ "redis-server", "/usr/local/etc/redis/redis.conf"]

redis.conf

port 6379
    dir /data
    pidfile /data/redis.pid
    logfile "/data/redis.log"
    repl-disable-tcp-nodelay yes
    no-appendfsync-on-rewrite yes
    maxmemory 2048m
    maxmemory-policy allkeys-lru
    requirepass abcd1234

注意：默认端口为6379，密码为abcd1234

## 生成镜像 ##

docker-compose build --no-cache

## 启动docker-compose ##

docker-compose up -d

## 测试 ##

进入容器，使用redis-cli测试。

# docker exec -it redis /bin/bash
    root@5fa954a74ae2:/data# redis-cli 
    127.0.0.1:6379> auth abcd1234
    OK

    # Server
