    What is the method for docker to install mysql and redis images?

    可直接默认下载最新镜像,也可以指定版本下载【注意,版本差异不大的软件可以直接下载最新版本,差异大的,例如java,mysql等,最好指定熟悉的版本进行下载

    docker pull redis

    启动镜像:

    docker run --name=redis -d --restart=always -p 6379:6379 redis
    • --name:别名

    • -d:后台运行,镜像不会随窗口关闭而关闭

    • --restart=always:随docker启动而自启 可以进行后配置:docker update --restart=always [容器名称|id]

    • -p:6379[主机端口]:6379[映射端口],如果有版本号,应该带上版本号redis:6.2.6

    挂载外部文件启动:

    提前创建好文件夹和文件,redis.conf如果没有特别的配置,可以参考(测试环境,生产环境换成本地,关闭密码即可):

    What is the method for docker to install mysql and redis images?

    #redis使用自定义配置文件启动
     
    docker run -v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf \
    -v /mydata/redis/data:/data \
    -d --name redis \
    --restart=always \
    -p 6379:6379 \
    redis:latest  redis-server /etc/redis/redis.conf
     
    #最后这一句代表自启动方式,redis启动默认不加载此处配置
    redis-server /etc/redis/redis.conf

    mysql安装下载

    镜像参考redis直接下载对应版本即可。

    -v:配置挂载,冒号左边为容器内部想要挂载出去的配置路径,右边为挂载的实际路径

    例如:mysql,挂载日志,数据,配置等信息到外部

    docker run -p 3306:3306 --name mysql \
    -v /mydata/mysql/log:/var/log/mysql \
    -v /mydata/mysql/data:/var/lib/mysql \
    -v /mydata/mysql/conf/my.cnf:/etc/mysql/my.cnf \
    -e MYSQL_ROOT_PASSWORD=root \
    -d mysql:5.7

    修改配置文件 my.cnf

    [client]
    default-character-set=utf8
    [mysql]
    default-character-set=utf8
    [mysqld]
    init_connect='SET collation_connection = utf8_unicode_ci'
    init_connect='SET NAMES utf8'
    character-set-server=utf8
    collation-server=utf8_unicode_ci
    skip-character-set-client-handshake
    skip-name-resolve
    lower_case_table_names=1

    最后说一下文件外部挂载的优缺点:

    • 优点:修改配置方便,不用每次都进入容器内部

    • 缺点:外部挂载方式镜像将不可以打包传递

    docker安装使用及用docker安装mysql,Redis,nacos

    安装

    卸载之前的docket

    sudo yum remove docker \
                       docker-client \
                       docker-client-latest \
                       docker-common \
                       docker-latest \
                       docker-latest-logrotate \
                       docker-logrotate \
                       docker-engine
    sudo yum install -y yum-utils  //设置存储库

    设置仓库地址,默认国外,也可以设置阿里云的

    sudo yum-config-manager \
        --add-repo \
        https://download.docker.com/linux/centos/docker-ce.repo
    yum-config-manager \
        --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

    安装docket引擎等组件

    sudo yum install docker-ce docker-ce-cli containerd.io

    启动docket

    sudo systemctl start docker

    配置加速镜像

    sudo mkdir -p /etc/docker
    sudo tee /etc/docker/daemon.json <<-&#39;EOF&#39;
    {
      "registry-mirrors": ["https://chqac97z.mirror.aliyuncs.com"]
    }
    EOF
    sudo systemctl daemon-reload
    sudo systemctl restart docker

    docket常用命令

    systemctl stop docker //关闭docker
    systemctl restart docker //重启docker
    systemctl status docker  //查看docker状态
    systemctl enable docker  //设置docker开机自启动
    
    docker images  //查看自己服务器的镜像列表
    docker search 镜像名  //搜索指定镜像
    docker search --filter=STARS=9000 mysql  //搜索 STARS >9000的 mysql 镜像
    docker pull 镜像名 //拉取docker仓库里的镜像
    docker pull 镜像名:tag  //拉取docker仓库里指定版本的镜像,具体版本号需要到镜像官网查看(https://hub.docker.com/search?type=image)

    docker rmi -f $(docker images -aq) //删除全部镜像  -a 意思为显示全部, -q 意思为只显示ID
    docker image rm 镜像名称/镜像ID  //强制删除镜像
    
    docker save 镜像名/镜像ID -o 镜像保存在哪个位置与名字
    docker save tomcat -o /myimg.tar //保存Tomcat到myimg.tar里
    docker commit -m="提交信息" -a="作者信息" 容器名/容器ID 提交后的镜像名:Tag
    
    docker ps  //查看正在运行容器列表
    docker ps -a  //查看所有容器 -----包含正在运行 和已停止的
    docker exec -it 容器名 路径//进入容器 里的路径
    #删除一个容器
    docker rm -f 容器名/容器ID
    #删除多个容器 空格隔开要删除的容器名或容器ID

    docker cp 容器ID/名称: 容器内路径  容器外路径        //容器内拷文件到外面
    docker cp 容器外路径 容器ID/名称: 容器内路径        //容器外拷文件到容器内
    docker run -it -d --name 容器别名 镜像名 --restart=always   //容器随着docker启动而启动
    docker update --restart=always 容器Id 或者 容器名 //修改容器启动配置(设置自启动)
    docker rename 容器ID/容器名 新容器名  //更改容器名
    
    docker logs container-id    //查看容器日志
    sudo docker info | grep "Docker Root Dir"  //查看docker工作目录
    du -hs /var/lib/docker/     //查看docker磁盘占用总体情况
    docker system df    //查看Docker的磁盘使用具体情况
    docker rm `docker ps -a | grep Exited | awk &#39;{print $1}&#39;`  //#  删除异常停止的容器
    docker rmi -f  `docker images | grep &#39;<none>&#39; | awk &#39;{print $3}&#39;` //删除名称或标签为none的镜像

    使用docker安装MySQL

    sudo docker pull mysql:5.7.39  //拉取mysql镜像到本地
    # --name指定容器名字 -v目录挂载 -p指定端口映射(宿主机端口:容器端口)  -e设置mysql参数 -d后台运行
    sudo docker run --name mysql -v /usr/local/mysql/data:/var/lib/mysql -v /usr/local/mysql/conf:/etc/mysql -v /usr/local/mysql/log:/var/log/mysql -v /usr/local/mysql/mysql-files:/var/lib/mysql-files/  -e MYSQL_ROOT_PASSWORD=root  -p 3306:3306 -d mysql:5.7
    docker exec -it 容器名称|容器id bin/bash  //进入容器里
    exit  //退出容器
     -v /usr/local/mysql/mysql-files:/var/lib/mysql-files/

    验证:用连接工具测试能不能连接成功,或window下cmd测试

    ssh -v -h 3306 IP

    使用docker安装Redis

    docker pull redis:6.0.10  //拉取镜像

    创建配置文件,docker-Redis里面默认没有配置文件,在宿主机创建并挂载到容器里

    mkdir /home/redis
    cd /home/redis
    vi redis.conf

    添加如下内容

    bind 0.0.0.0  开启远程权限
    appendonly yes  开启aof持久化

    启动Redis容器并挂载文件

    docker run --name redis  -v /home/redis/data:/data  -v /home/redis/redis.conf:/usr/local/etc/redis/redis.conf -p 6379:6379 -d redis:6.0.10  redis-server /usr/local/etc/redis/redis.conf
    docker exec -it redis redis-cli //进入Redis客户端

    安装nacos

    拉取镜像

    docker pull nacos/nacos-server

    查看镜像

    docker images

    启动容器

    docker run --env MODE=standalone --name mynacos -d -p 8848:8848 docker.io/nacos/nacos-server

    查看启动日志

    docker logs -f mynacos

    日志中显示nacos服务地址为:

    http://172.18.0.2:8848/nacos/index.html

    默认账号密码都是nacos

    进入nacos容器查看配置

    docker ps
    docker exec -it 容器名或ID /bin/bash
    ls
    cd conf/
    ls

    修改启动配置文件

    进入

    docker exec -it nacos /bin/bash

    进入启动脚本

    cd /home/nacos/bin
    vim docker-startup.sh

    Redis: Beyond SQL - The NoSQL PerspectiveRedis: Beyond SQL - The NoSQL PerspectiveMay 08, 2025 am 12:25 AM

    Redis goes beyond SQL databases because of its high performance and flexibility. 1) Redis achieves extremely fast read and write speed through memory storage. 2) It supports a variety of data structures, such as lists and collections, suitable for complex data processing. 3) Single-threaded model simplifies development, but high concurrency may become a bottleneck.

    Redis: A Comparison to Traditional Database ServersRedis: A Comparison to Traditional Database ServersMay 07, 2025 am 12:09 AM

    Redis is superior to traditional databases in high concurrency and low latency scenarios, but is not suitable for complex queries and transaction processing. 1.Redis uses memory storage, fast read and write speed, suitable for high concurrency and low latency requirements. 2. Traditional databases are based on disk, support complex queries and transaction processing, and have strong data consistency and persistence. 3. Redis is suitable as a supplement or substitute for traditional databases, but it needs to be selected according to specific business needs.

    Redis is primarily a database, but it is more than just a database. 1. As a database, Redis supports persistence and is suitable for high-performance needs. 2. As a cache, Redis improves application response speed. 3. As a message broker, Redis supports publish-subscribe mode, suitable for real-time communication.

    Redis is an open source memory data structure storage used as a database, cache and message broker, suitable for scenarios where fast response and high concurrency are required. 1.Redis uses memory to store data and provides microsecond read and write speed. 2. It supports a variety of data structures, such as strings, lists, collections, etc. 3. Redis realizes data persistence through RDB and AOF mechanisms. 4. Use single-threaded model and multiplexing technology to handle requests efficiently. 5. Performance optimization strategies include LRU algorithm and cluster mode.

    Redis: Caching, Session Management, and MoreRedis: Caching, Session Management, and MoreMay 01, 2025 am 12:03 AM

    Redis's functions mainly include cache, session management and other functions: 1) The cache function stores data through memory to improve reading speed, and is suitable for high-frequency access scenarios such as e-commerce websites; 2) The session management function shares session data in a distributed system and automatically cleans it through an expiration time mechanism; 3) Other functions such as publish-subscribe mode, distributed locks and counters, suitable for real-time message push and multi-threaded systems and other scenarios.
