Docker
  1. 下載安裝 docker-compose
curl -L "https://github.com/docker/compose/releases/download/v2.17.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# curl -L "https://get.daocloud.io/docker/compose/releases/download/v2.17.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

# 解除安裝
rm -rf /usr/local/bin/docker-compose
  1. 常用命令
Compose常用命令
docker-compose -h                           # 檢視幫助
docker-compose up                           # 啟動所有docker-compose服務
docker-compose up -d                        # 啟動所有docker-compose服務並後臺執行
docker-compose down                         # 停止並刪除容器、網路、卷、映象.
docker-compose exec  yml裡面的服務id         # 進入容器例項內部  docker-compose exec docker-compose.yml檔案中寫的服務id /bin/bash
docker-compose ps                           # 展示當前docker-compose編排過的執行的所有容器
docker-compose top                          # 展示當前docker-compose編排過的容器程序
docker-compose logs  yml裡面的服務id         # 檢視容器輸出日誌
docker-compose config     # 檢查配置
docker-compose config -q  # 檢查配置, 有問題才有輸出
docker-compose restart    # 重啟服務
docker-compose start      # 啟動服務
docker-compose stop       # 停止服務

  1. 建立使用者表
CREATE TABLE `t_user` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(50) NOT NULL DEFAULT '' COMMENT '使用者名稱',
  `password` varchar(50) NOT NULL DEFAULT '' COMMENT '密碼',
  `sex` tinyint(4) NOT NULL DEFAULT '0' COMMENT '性別 0=女 1=男 ',
  `deleted` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '刪除標誌, 預設0不刪除, 1刪除',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新時間',
  `create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '建立時間',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='使用者表'
  1. docker-compose.yml 模板
