9、阿里云 Ubuntu22.04、安装docker、mysql、mongodb

一、开启远程登录

sudo vim /etc/ssh/sshd_config
 
修改下面的值
PermitRootLogin yes
PubkeyAuthentication yes
 
sudo systemctl reload sshd
 
sudo passwd root

二、安装docker

卸载旧版本

旧版本的 Docker 称为 docker 或者 docker-engine，使用以下命令卸载旧版本：

sudo apt-get remove docker docker-engine docker.io

使用 APT 安装

由于 apt 源使用 HTTPS 以确保软件下载过程中不被篡改。因此，我们首先需要添加使用 HTTPS 传输的软件包以及 CA 证书。

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release

鉴于国内网络问题，强烈建议使用国内源，官方源请在注释中查看。

为了确认所下载软件包的合法性，需要添加软件源的 GPG 密钥。

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
 
 
# 官方源
# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

然后，我们需要向 sources.list 中添加 Docker 软件源

echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 
 
# 官方源
# $ echo \
#   "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
#   $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

安装 Docker

更新 apt 软件包缓存，并安装 docker-ce：

sudo apt-get update
 
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
 
# 验证安装版本
docker --version
 
# 显示出
Docker version 27.1.1, build 6312585

三、安装docker-compose

mkdir /root/folder
cd /root/folder
wget https://github.com/docker/compose/releases/download/v2.29.1/docker-compose-linux-x86_64
 
# 下载很慢可以浏览器下载后上车到服务器
scp docker-compose-linux-x86_64 root@x.x.x.x:/root/folder
 
sudo mv /root/folder/docker-compose-linux-x86_64 /usr/local/bin/docker-compose
 
# 赋予可执行权限：
sudo chmod +x /usr/local/bin/docker-compose
 
# 验证 Docker Compose 是否正确安装：
docker-compose --version
 
# 显示出
# Docker Compose version v2.29.1

四、安装mysql和mongodb

mkdir -p /root/folder/docker-data
cd /root/folder/docker-data
mkdir data
mkdir -p data/mysql_data
mkdir -p data/mongodb_data

vim docker-compose.yml

networks:
    docker-net-01:
        driver: bridge
 
services:
    mysql:
        container_name: mysql_5.7_01
        image: "mysql:5.7"
        restart: always
        ports:
            - 3306:3306
        environment:
            MYSQL_ROOT_PASSWORD: rootpassword
            MYSQL_DATABASE: mydatabase
            MYSQL_USER: myuser
            MYSQL_PASSWORD: mypassword
        volumes:
            - ./data/mysql_data:/var/lib/mysql
        networks:
            - docker-net-01
 
    mongodb:
        container_name: mongodb_4.0_01
        image: "mongo:4.0"
        restart: always
        ports:
            - 27017:27017
        environment:
            MONGO_INITDB_ROOT_USERNAME: root
            MONGO_INITDB_ROOT_PASSWORD: rootpassword
        volumes:
            - ./data/mongodb_data:/data/db
        networks:
            - docker-net-01
 

 如果想要安装其他的中间件可以修配配置文件，例如安装Redis

networks:
    docker-net-01:
        driver: bridge
 
services:
    redis:
        container_name: redis_01
        image: "redis:latest"
        restart: always
        ports:
            - 6379:6379
        volumes:
            - ./data/redis_data:/data
        environment:
            - REDIS_PASSWORD=tiktok
            - ALLOW_EMPTY_PASSWORD=no
        networks:
            - docker-net-01
            
    mysql:
        container_name: mysql_5.7_01
        image: "mysql:5.7"
        restart: always
        ports:
            - 3306:3306
        environment:
            MYSQL_ROOT_PASSWORD: rootpassword
            MYSQL_DATABASE: mydatabase
            MYSQL_USER: myuser
            MYSQL_PASSWORD: mypassword
        volumes:
            - ./data/mysql_data:/var/lib/mysql
        networks:
            - docker-net-01
 
    mongodb:
        container_name: mongodb_4.0_01
        image: "mongo:4.0"
        restart: always
        ports:
            - 27017:27017
        environment:
            MONGO_INITDB_ROOT_USERNAME: root
            MONGO_INITDB_ROOT_PASSWORD: rootpassword
        volumes:
            - ./data/mongodb_data:/data/db
        networks:
            - docker-net-01

链接进入容器，比如进入 “mysql_5.7_01”

docker exec -it mysql_5.7_01 bash

进入容器后，你就可以在容器内执行命令或操作 MySQL 了。如果你需要直接连接到 MySQL 数据库，你可以使用 MySQL 客户端工具（如 mysql 命令行工具），密码在 docker-compose.yml 的配置文件里面有，看自己的设置：

mysql -u root -p
