本文作者：[wangwenhai] # 概要：记录近期工作中的一些常见操作.

1.Docker相关

1.1 Windows下

windows安装Docker首先要启用Hyper-V：

1. 可以通过【程序和功能】=》【打开或关闭 Windows 功能】=》勾选【Hyper-V】来启用Hyper-V，

   

   

2. 也可以通过管理员执行以下Powershell脚本：

   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

1.2 Linux下

1. Ubuntu - server 安装Docker

   sudo apt-get install apt-transport-https  ca-certificates curl gnupg-agent software-properties-common -y
   sudo add-apt-repository  "deb [arch=amd64] https://download.docker.com/linux/ubuntu   $(lsb_release -cs)   stable"
   sudo apt-get update  -y
   sudo apt-get install docker-ce docker-ce-cli containerd.io -y

2. Docker强制删除容器

   
   1. 删除所有容器
   # 先停止所有容器 
   $ docker stop $(docker ps -a -q) 
   # 删除 
   $ docker rm $(docker ps -a -q)
   2. 批量删除部分容器
   # 先停止所有容器 
   $ docker stop $(docker ps | grep rock | awk '{print $1}') 
   # 删除 
   $ docker rm $(docker ps -a| grep rock | awk '{print $1}')

3. UbuntuServer安装MINIKUBE

   curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
   chmod +x minikube
   sudo mkdir -p /usr/local/bin/
   sudo install minikube /usr/local/bin/
   minikube start --registry-mirror=https://registry.docker-cn.com --memory=4096 --image-repository=registry.cn-hangzhou.aliyuncs.com/google_containers

4. DockerMysql8认证问题

   Navicat连接失败的时候：

   alter user root@localhost identified by 'password' password expire never;
   alter user root@localhost identified with mysql_native_password by 'password';
   flush privileges;

   2. 环境搭建

我们有时候需要快速搭建开发环境，比如数据库之类的，我这里总结了一个ComposeFile，直接即可搭建Mongo，Mysql，Redis开发环境。

version: '3.1'
# 定义网络
# 节点	IP
# Mysql	      192.168.1.100/24
# Mongodb	  192.168.1.101/24
# Redis	      192.168.1.102/24
networks:
  ezlinker_net:
    driver: bridge
    ipam:
      config:
        - subnet: 192.168.1.0/24
# 定义服务
services:
  # Mysql
  mysql:
    # 使用最新版Mysql
    image: mysql
    container_name: "ezlinker_mysql"
    # 环境变量
    environment:
      TZ: Asia/Shanghai
      MYSQL_ROOT_PASSWORD: "root"
      MYSQL_USER: 'root'
      MYSQL_PASS: 'root'
    # 映射数据卷
    volumes:
      - ~/docker/ezlinker/mysql8/data:/var/lib/mysql
      - ~/docker/ezlinker/mysql8/log:/var/log/mysql
      - ~/docker/ezlinker/mysql8/mysql-files:/var/lib/mysql-files
    restart: always
    # 对外断口
    ports:
      - 3306:3306
      - 33060:33060
    # 启动后执行命令
    command:
      --default-authentication-plugin=mysql_native_password
      --character-set-server=utf8mb4
      --collation-server=utf8mb4_general_ci
      --explicit_defaults_for_timestamp=true
      --lower_case_table_names=1
      --max_allowed_packet=128M;
    # 日志限制
    logging:
      driver: "json-file"
      options:
        max-size: "200k"
        max-file: "10"
    # 网络
    networks:
      ezlinker_net:
        ipv4_address: 192.168.1.100
  # Mongodb
  mongo:
    image: mongo
    container_name: ezlinker_mongo
    volumes:
      - ~/docker/ezlinker/mongodb/db:/data/db
      - ~/docker/ezlinker/mongodb/configdb/:/data/configdb
    ports:
      - "27017:27017"
    restart: always
    command:
      --bind_ip 0.0.0.0
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: ezlinker_mongo
    networks:
      ezlinker_net:
        ipv4_address: 192.168.1.101
  # Redis
  redis:
    image: redis
    container_name: ezlinker_redis
    command: redis-server --requirepass ezlinker_redis --appendonly yes
    ports:
      - "56379:6379"
    volumes:
      - ~/docker/ezlinker/redis/data:/data
    restart: always
    networks:
      ezlinker_net:
        ipv4_address: 192.168.1.102

直接用docker compose来构建即可：

docker-compose up -d
