    今天开始录一些docker布署的视频,每个程序员都应该会这些先准备虚拟机,
    我这里准备的是ubuntu18,配置是2核4G
    第一个视频先准备好docker和docker-compose环境
    先来docker的安装
    习惯将docker放在这个目录/usr/local/docker
    安装docker
    curl -fsSL get.docker.com -o get-docker.sh这一步是下载docker官方的安装脚本
    sudo sh get-docker.sh --mirror Aliyun执行安装脚本,指定镜像为阿里云,这样安装快些
    再提前从官网下载好docker-compose,我这已经下载好了,通过ftp软件,上传到虚拟机上
    docker已经安装好了,先把docker的镜像源配置一下
    我这台虚拟机之前配置过docker,我先把daemon.json清空了
    {
    "registry-mirrors":["https://docker.mirrors.ustc.edu.cn"]
    }
    把上面的配置粘贴到/etc/docker/daemon.json里
    service docker restart重启一次docker服务
    到这里docker就配置好了
    现在来配置docker-compose,刚才已经通过ftp上传到了虚拟机。
    只需要移动到/usr/local/bin/下,将设置u+x权限,让当前用户可以执行即可docker-compose也好了
    docker环境已经准备完毕

    ======================================================================

    先在/usr/local/docker目录下创建nginx目录,用于存储nginx容器的配置和nginx的日志等

    cd /usr/local/docker
    mkdir nginx
    cd nginx/

    docker本身的命令很长,不利于管理,这里采用docker-compose方式来管理容器
    先在/usr/local/docker/nginx下创建docker-compose.yml文件,用来编写nginx容器的配置

    从nginx官网下载nginx的安装包,上传到虚拟机上
    再复制准备好的docker-compose.yml内容

    echo > docker-compose.yml <<EOF
    version: '3.1' #指定docker-compose版本
    services: #定义服务
    nginx: #服务名
    restart: always #重启
    build: build #指定构建容器的目录
    container_name: nginx #指定容器名
    ports: #宿主机端口
    - 80:80
    volumes: #宿主机目录映射到容器中
    - ./nginx.conf:/usr/local/nginx/conf/nginx.conf #将宿主机上当前目录下的nginx.conf文件映射到容器中/usr/local/nginx/conf/nginx.conf
    - ./1og:/var/log/nginx/
    - ./wwwroot:/usr/share/nginx/html
    EOF

    cd /usr/local/docker/nginx
    mkdir build
    vi build/Dockerfile

    #当前镜像基于
    FROM ubuntu:xenial
    #设置工作目录
    WORKDIR /etc/apt
    RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse' > sources.list
    RUN echo 'deb http://mirrors . aliyun. com/ ubuntu/ xenial-security main restricted universe multiverse' 》> sources.list 
    RUN echo 'deb http: //mirrors . aliyun. com/ubuntu/ xenial-updates main restricted universe multiverse' >> sources.list
    RUN echo 'deb http: //mirrors . aliyun . com/ubuntu/ xenial-backports main restricted universe multiverse' >> sources .list
    RUN apt -get update
    
    #安装依赖
    RUN apt-get install unzip make gcc libpcre3-dev zlib1g-dev --assume-yes
    
    #复制工具包
    # ADD命令会将.tar.gz文件复制到指定目录,井自动解压
    ADD nginx-1.17.7.tar.gz /ust/1ocal/src
    
    #设置工作目录
    WORKDIR /usr/1oca1/src/nginx-1.17.7
    
    #编译nginx
    RUN rm -rf ./Makefile 
    RUN ./configure
    RUN make && make install
    WORKDIR /
    #最后运行脚本,启动nginx
    CMD ["/usr/1ocal/nginx/sbin/nginx", "-C", "/usr/local/nginx/conf/nginx.conf", "-g", "daemon off;"]
    

    现在将nginx安装包移到build目录下
    再复制nginx配置文件

    mv /root/nginx-1.17.7.tar.gz ./build/

    }

    http {
    server_tokens off;
    include mime .types ;
    default_type application/octet-stream;

    access_ log /var/log/nginx/access . log;

    access_log off;
    error_log /var/log/nginx/error.log;

    keepalive_timeout 65;
    client_max_body_size 20m;

    gzip on;
    gzip_disable "msie6";
    gzip_min_length 1000;
    gzip_proxied expired no-cache no-store private auth;
    gzip_types text/plain application/xml applicat ion/javascript text/css application/x-javascript;

    server {
    listen 80;
    server_name test;
    root /usr/share/nginx/html/;
    }
    }

    mkdir log
    mkdir wwwroot

    docker-compose up

    docker-compose up -d
