docker-compose 安装mariadb

1、创建需要映射的目录

mkdir -p /docker/mariadb/{config,data,log}                                                                                           

2、编写docker-compose.yml

cat > /docker/mariadb/docker-compose.yml << EOF

version: '3.1'

services:

  mariadb:

    image: mariadb:latest

    restart: always

    container_name: mariadb

    ports:

      # 端口映射

      - 3305:3306

    volumes:

      # 容器与宿主机时间同步

      - /etc/localtime:/etc/localtime

      # 数据库目录映射

      - /docker/mariadb/data:/var/lib/mysql

      # （不推荐）数据库配置文件映射（如果需要自己配置的话打开--他会覆盖docker容器中的配置文件夹-如果是空文件夹那么会把容器内的配置文件全都替换成空）

      #- ./config/data/mariadb-config/my.cnf:/etc/mysql/my.cnf

      # （推荐）如果要使用自定义的MySQL配置，则可以在主机上的目录中创建备用配置文件，然后将该目录位置/etc/mysql/conf.d安装在mariadb容器内。自己所需的配置文件可以放在自己服务器./config/data/mariadb-config里面，

      - /docker/mariadb/config:/etc/mysql/conf.d

      - /docker/mariadb/log:/var/log

    environment:

      TIME_ZONE: Asia/Shanghai

      MYSQL_ROOT_PASSWORD: root

3、编写自定义配置文件

cat > /docker/mariadb/config/my.cnf <

# MariaDB database server configuration file.

#

# You can copy this file to one of:

# - "/etc/mysql/my.cnf" to set global options,

# - "~/.my.cnf" to set user-specific options.

#

# One can use all long options that the program supports.

# Run program with --help to get a list of available options and with

# --print-defaults to see which it would actually understand and use.

#

# For explanations see

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients

# It has been reported that passwords should be enclosed with ticks/quotes

# escpecially if they contain "#" chars...

4、给/docker/mariadb文件夹读写权限

chmod -R 777 /docker/mariadb

5、运行

docker-compose up -d
