1. 安装

WindTerm下载：
https://github.com/kingToolbox/WindTerm/releases/download/2.6.0/WindTerm_2.6.1_Windows_Portable_x86_64.zip

# 移除旧版本docker sudo yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-engine # 配置docker yum源。 sudo yum install -y yum-utils sudo yum-config-manager \ --add-repo \ http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # 安装 最新 docker sudo yum install -y docker-ce docker-ce-cli containerd.io docker-buildx-pl ugin docker-compose-plugin

启动& 开机启动docker； enable + start 二合一

systemctl enable docker --now

配置加速

sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://mirror.ccs.tencentyun.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker

命令

#查看运行中的容器 docker ps #查看所有容器 docker ps -a #搜索镜像 docker search nginx #下载镜像 docker pull nginx #下载指定版本镜像 docker pull nginx:1.26.0 #查看所有镜像 docker images #删除指定id的镜像 docker rmi e784f4560448 #运行一个新容器 docker run nginx #停止容器 docker stop keen_blackwell #启动容器 docker start 592 #重启容器 docker restart 592 #查看容器资源占用情况 docker stats 592 #查看容器日志 docker logs 592 #删除指定容器 docker rm 592 #强制删除指定容器 docker rm -f 592

后台启动容器

docker run -d --name mynginx nginx

后台启动并暴露端口

docker run -d --name mynginx -p 80:80 nginx

进入容器内部

docker exec -it mynginx /bin/bash

提交容器变化打成一个新的镜像

docker commit -m “update index.html” mynginx mynginx:v1.0

保存镜像为指定文件

docker save -o mynginx.tar mynginx:v1.0

删除多个镜像

docker rmi bde7d154a67f 94543a6c1aef e784f4560448

加载镜像

docker load -i mynginx.tar

登录 docker hub

docker login

重新给镜像打标签

docker tag mynginx:v1.0 leifengyang/mynginx:v1.0
#推送镜像
docker push leifengyang/mynginx:v1.0
3. 存储
两种方式，注意区分：
目录挂载： -v /app/nghtml:/usr/share/nginx/html
卷映射： -v ngconf:/etc/nginx

docker run -d -p 99:80
-v /app/nghtml:/usr/share/nginx/html
-v ngconf:/etc/nginx
–name app03
nginx
4.网络
创建自定义网络，实现主机名作为稳定域名访问。
4.1. Redis主从同步集群
#自定义网络
docker network create mynet
#主节点
docker run -d -p 6379:6379
-v /app/rd1:/bitnami/redis/data
-e REDIS_REPLICATION_MODE=master
-e REDIS_PASSWORD=123456
–network mynet --name redis01
bitnami/redis
#从节点
docker run -d -p 6380:6379
-v /app/rd2:/bitnami/redis/data
-e REDIS_REPLICATION_MODE=slave
-e REDIS_MASTER_HOST=redis01
-e REDIS_MASTER_PORT_NUMBER=6379
-e REDIS_MASTER_PASSWORD=123456
-e REDIS_PASSWORD=123456
–network mynet --name redis02
bitnami/redis
4.2. 启动MySQL

docker run -d -p 3306:3306 \ -v /app/myconf:/etc/mysql/conf.d \ -v /app/mydata:/var/lib/mysql \ -e MYSQL_ROOT_PASSWORD=123456 \ mysql:8.0.37-debian

Docker Compose
5.1. 命令式安装

#创建网络 docker network create blog #启动mysql docker run -d -p 3306:3306 \ -e MYSQL_ROOT_PASSWORD=123456 \ -e MYSQL_DATABASE=wordpress \ -v mysql-data:/var/lib/mysql \ -v /app/myconf:/etc/mysql/conf.d \ --restart always --name mysql \ --network blog \ mysql:8.0 #启动wordpress docker run -d -p 8080:80 \ -e WORDPRESS_DB_HOST=mysql \ -e WORDPRESS_DB_USER=root \ -e WORDPRESS_DB_PASSWORD=123456 \ -e WORDPRESS_DB_NAME=wordpress \ -v wordpress:/var/www/html \ --restart always --name wordpress-app \ --network blog \ wordpress:latest

5.2. compose.yaml

name: myblog services: mysql: container_name: mysql image: mysql:8.0 ports: - "3306:3306" environment: - MYSQL_ROOT_PASSWORD=123456 - MYSQL_DATABASE=wordpress volumes: - mysql-data:/var/lib/mysql - /app/myconf:/etc/mysql/conf.d restart: always networks: - blog wordpress: image: wordpress ports: - "8080:80" environment: WORDPRESS_DB_HOST: mysql WORDPRESS_DB_USER: root WORDPRESS_DB_PASSWORD: 123456 WORDPRESS_DB_NAME: wordpress volumes: - wordpress:/var/www/html restart: always networks: - blog depends_on: - mysql volumes: mysql-data: wordpress: networks: blog:

5.3. 特性
增量更新
数据不删
修改 Docker Compose 文件。重新启动应用。只会触发修改项的重新启动。
默认就算down了容器，所有挂载的卷不会被
移除。比较安全
6. Dockerfile
app.jar

FROM openjdk:17 LABEL author=leifengyang COPY app.jar /app.jar EXPOSE 8080 ENTRYPOINT ["java","-jar","/app.jar"]

#Disable memory paging and swapping performance sudo swapoff -a # Edit the sysctl config file sudo vi /etc/sysctl.conf # Add a line to define the desired value # or change the value if the key exists, # and then save your changes. vm.max_map_count=262144 # Reload the kernel parameters using sysctl sudo sysctl -p # Verify that the change was applied by checking the value cat /proc/sys/vm/max_map_count

7.1. yaml

注意：将下面文件中 kafka 的 119.45.147.122 改为你自己的服务

7.2. 启动

在 compose.yaml 文件所在的目录下执行

docker compose up -d

等待启动所有容器

tip：如果重启了服务
器，可能有些容器会启动
所有程序都可运行成功，并且不会丢失数据。请放心使用。
失败。再执行一遍 docker compose up -d 即可。
