安装docker和docker-compose

安装这个很简单，就不写了。。。。

添加用户到docker组

把操作docker的用户，添加到docker组，这样就不用每次都要切root或者输入sudo密码（啥都用root用户是一种愚蠢的行为。。。小声）

1
sudo usermod -a -G docker username

新建文件夹，创建docker-compose.yml 文件

1
2
mkdir test
cd test && vim docker-compose.yml

# Use root/123456 as user/password for mariadb
# adminer is a simple tool to control mariadb
# Use 123456 as redis password
version: '3.1'

services:
  mariadb:
    image: mariadb
    container_name: db
    restart: always
    ports:
      - "3306:3306"
    volumes:
      - ./mariadb/data:/var/lib/mysql:rw
    environment:
      MARIADB_ROOT_PASSWORD: "123456"
  adminer:
    image: adminer
    container_name: adminer
    restart: always
    ports:
      - 8080:8080
  redis:
    image: redis
    container_name: redis
    restart: always
    volumes:
      - ./redis/data:/data:rw
      - ./redis/conf/redis.conf:/usr/local/etc/redis/redis.conf:rw
    command: redis-server /usr/local/etc/redis/redis.conf
    ports:
      - 6379:6379

创建 redis.conf

2
mkdir -p redis/conf
vim redis/conf/redis.conf

在docker-compose.yml所在目录启动docker

1
docker-compose up -d

如此便可以后台运行mariadb,redis 和adminer了。

如果报错ipv4 ip_forward相关的错误;

写入net.ipv4.ip_forward=1到/etc/sysctl.d/ipv4-forward.conf，然后重启就好
