Docker-compose封装mysql并初始化数据以及redis

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

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
127.0.0.1:6379> info
# Server
redis_version:4.0.10
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:3e68f04515f466a2
redis_mode:standalone
os:Linux 3.10.0-957.el7.x86_64 x86_64
