docker 命令（我使用过的）（docker命令详解大全）

是否安装 docker:
    docker version

启动 docker:
    service docker start

查看本机可用镜像：
    docker images

删除镜像：

　docker rmi 镜像 id

查看正在运行的镜像：
    docker ps -l
    
结束正在运行的镜像：
    docker stop imagesId/name    
    
docker 进入具体进程：

　　方法一：
    　　　　1、docker ps        --》 获得进程 id
    　　　　2、docker inspect -f {{.State.Pid}} 进程 id     --》 活得 nsenter 需要的 id
   　　　　 3、nsenter --target 第二步得到的 id --mount --uts --ipc --net --pid     --> 进入具体的进程

　　方法二：

　　　　　docker exec -it 镜像名称（你运行镜像时，起的名字，或者 id） /bin/bash

docker 与 进程的文件拷贝
    1、docker ps        --》 获得进程 id
    2、docker cp 需要拷贝到进程的文件  第一步得到的进程 id: 需要拷贝到进程的路径
    将进程内的文件拷贝出来
       docker cp 第一步得到的进程 id: 需要在进程中拷贝的文件路径  需要拷贝到宿主机的文件         

重启 docker 内的进程：
    docker restart docker 进程名称

mysql:
    docker run --name mysql --privileged=true -e MYSQL_ROOT_PASSWORD=root -p 3306:3306 -d mysql:5.7

多实例：（name 和宿主机的端口，需要有差异）
    docker run --name mysql7 --privileged=true -e MYSQL_ROOT_PASSWORD=root -p 3307:3306 -d mysql:5.7

mongo:

　　docker run --name mongo-1 -p 27017:27017 -d mongo: 版本号

　　--name: 运行后的服务名称

　　-p: 本机端口：镜像服务端口

　　-d: 守护进程

docker构建nginx容器系列问题

background : 最近为小伙伴们筹划docker系列的技术分享，研究了一会docker相关技术， 在此记录一下构建nginx容器时候的坑

1.nginx服务器根目录问题

docker 官方镜像提供的nginx基于debian/jessie平台，其文件结构和ubuntu中的nginx中并不相同

eg:

run一个niginx容器

<span>//80端口被占用，so...</span>
$ sudo docker run <span>-it</span><span>-p</span><span>800</span>:<span>800</span> nginx
$ sudo docker ps 

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                   NAMES
<span>1801</span>a32aab54        nginx               <span>"nginx -g ''daemon off"</span><span>2</span> minutes ago       Up <span>2</span> minutes        <span>80</span>/tcp, <span>443</span>/tcp, <span>0.0</span><span>.0</span><span>.0</span>:<span>800</span><span>-&gt;</span><span>800</span>/tcp   berserk_kare

进入容器内部

<span>$ </span>sudo docker exec -it <span>1801</span>a32aab54 /bin/bash
root<span>@1801a32aab54</span><span>:/</span><span># </span>

查看nginx目录

<span># cd /etc/nginx/</span>
conf<span>.d</span>/         koi-utf         mime<span>.types</span>      nginx<span>.conf</span>      uwsgi_params    
fastcgi_params  koi-win         modules/        scgi_params     win-utf  

可以看到不仅没有熟悉的 /sites-available，也没有 /sites-enabled

继续查看nginx配置

<span># cat /conf.d/default.conf</span><span>server</span> {
    listen       <span>80</span>;
    server_name  localhost;

    <span>#charset koi8-r;</span><span>#access_log  /var/log/nginx/log/host.access.log  main;</span>    location / {
        root   /usr/share/nginx/html;
        <span>index</span><span>index</span>.html <span>index</span>.htm;
    }

    <span>#error_page  404              /404.html;</span><span># redirect server error pages to the static page /50x.html</span><span>#</span>
    error_page   <span>500</span><span>502</span><span>503</span><span>504</span>  /<span>50</span>x.html;
    location = /<span>50</span>x.html {
        root   /usr/share/nginx/html;
    }
    <span>#...省略php-fpm配置，好长..</span>
}

根目录配置: root /usr/share/nginx/html;

测试

<span># cd /usr/share/nginx/html</span><span># touch index.html</span><span># echo "test nginx in docker" &gt;index.html</span>

php-fpm配置相关

以上就介绍了167 docker docker构建nginx容器系列问题，包括了docker,nginx方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
