标签：compose log -- sql db innodb mysql size

1、应用场景：

使用docker-compose 部署后台系统、nacos、seata 时，由于他们都各有自己的一个数据库，且在容器启动的时候要保证这三个数据库都创建完成，否则后台系统起不来，或者nacos 报错找不到数据库，seata 一样

2、构建数据：

执行docker-compose up -d

1）目录结构：

2）test1_db.sql

-- ----------------------------
-- 创建数据库
-- ----------------------------
drop database IF EXISTS test1_db;
CREATE DATABASE test1_db DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

use test1_db
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for test_table
-- ----------------------------
DROP TABLE IF EXISTS `test_table`;
CREATE TABLE `test_table` (
`name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

SET FOREIGN_KEY_CHECKS = 1;

3) test2_db.sql

-- ----------------------------
-- 创建数据库 
-- ----------------------------
drop database IF EXISTS test2_db;
CREATE DATABASE test2_db DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

use test2_db
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for test2_table
-- ----------------------------
DROP TABLE IF EXISTS `test2_table`;
CREATE TABLE `test2_table`  (
  `id` int(11) NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;

SET FOREIGN_KEY_CHECKS = 1;

4) init.sql

-- ----------------------------
-- 执行顺序
-- ----------------------------
source /opt/db/test1_db.sql;
source /opt/db/test2_db.sql

5) mysqld.cnf

6) dockerfile

# 基础镜像

# author

ADD mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf

7) docker-compose.yml

version : '3.8'
services:
  mysql:
    container_name: mysql
    image: mysql:5.7
    build:
      context: ./mysql
    ports:
      - "3306:3306"

    environment:
      MYSQL_ROOT_PASSWORD: 123123
    restart: always

3、执行docker-compose up -d

4、连接数据库
