以下命令使用 NGINX 默认的配置来启动一个 Nginx 容器实例：
$ docker run --name runoob-nginx-test -p 8081:80 -d nginx
- runoob-nginx-test 容器名称。
- the -d设置容器在在后台一直运行。
- the -p 端口进行映射，将本地 8081 端口映射 到容器内部的 80 端口。
执行以上命令会生成一串字符串，类似 6dd4380ba70820bd2acc55ed2b326dd8c0ac7c93f68f0067daecad82aef5f938 ，这个表示容器的 ID，一般可作为日志的文件名。
我们可以使用 docker ps 命令查看容器是否有在运行：
$ docker psCONTAINER ID IMAGE ... PORTS NAMES6dd4380ba708 nginx ... 0.0.0.0:8081->80/tcp runoob-nginx-test
PORTS 部分表示端口映射，本地的 8081 端口映射到容器内部的 80 端口。
在浏览器中打开 ，效果如下：
nginx 部署
首先，创建目录 nginx, 用于存放后面的相关东西。
$ mkdir -p ~/nginx/www ~/nginx/logs ~/nginx/conf
拷贝容器内 Nginx 默认配置文件到本地当前目录下的 conf 目录，容器 ID 可以查看 docker ps 命令输入中的第一列：
docker cp 6dd4380ba708:/etc/nginx/nginx.conf ~/nginx/conf
- www : 目录将映射为 nginx 容器配置的虚拟目录。
- logs : 目录将映射为 nginx 容器的日志目录。
- conf : 目录里的配置文件将映射为 nginx 容器的配置文件。
部署命令
$ docker run -d -p 8082:80 --name runoob-nginx-test-web -v ~/nginx/www:/usr/share/nginx/html -v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v ~/nginx/logs:/ var /log/nginx nginx
命令说明：
- -p 8082:80： 将容器的 80 端口映射到主机的 8082 端口。
- –name runoob-nginx-test-web： 将容器命名为 runoob-nginx-test-web。
- -v ~/nginx/www:/usr/share/nginx/html： 将我们自己创建的 www 目录挂载到容器的 /usr/share/nginx/html。
- -v ~/nginx/conf/nginx.conf:/etc/nginx/nginx.conf： 将我们自己创建的 nginx.conf 挂载到容器的 /etc/nginx/nginx.conf。
- -v ~/nginx/logs:/var/log/nginx： 将我们自己创建的 logs 挂载到容器的 /var/log/nginx。
启动以上命令后进入 ~/nginx/www 目录：
$ cd ~/nginx/www
创建 index.html 文件，内容如下：
<!DOCTYPE html><html><head><meta charset="utf-8"><title>菜鸟教程(runoob.com)</title></head><body> <h1>我的第一个标题</h1> <p>我的第一个段落。</p></body></html>
输出结果为：
相关命令
如果要重新载入 NGINX 可以使用以下命令发送 HUP 信号到容器：
$ docker kill -s HUP container-name
重启 NGINX 容器命令：
$ docker restart container-name

这里我们拉取官方的镜像,标签为5.6-fpm
runoob@runoob:~/php-fpm$ docker pull php:5.6-fpm
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为php,标签为5.6-fpm的镜像。
runoob@runoob:~/php-fpm$ docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEphp 5.6-fpm 025041cd3aa5 6 days ago 456.3 MB
Nginx + PHP 部署
Nginx 部署可以查看：Docker 安装 Nginx，一些 Nginx 的配置参考这篇文章。
启动 PHP：
$ docker run --name myphp-fpm -v ~/nginx/www:/www -d php:5.6-fpm
命令说明：
- –name myphp-fpm : 将容器命名为 myphp-fpm。
- -v ~/nginx/www:/www : 将主机中项目的目录 www 挂载到容器的 /www
创建 ~/nginx/conf/conf.d 目录：
mkdir ~/nginx/conf/conf.d
在该目录下添加 ~/nginx/conf/conf.d/runoob-test-php.conf 文件，内容如下：
server { listen 80; server_name localhost; location / { root /usr/share/nginx/html; index index.html index.htm index.php; } error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location ~ \.php$ { fastcgi_pass php:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /www/$fastcgi_script_name; include fastcgi_params; }}
配置文件说明：
- php:9000 : 表示 php-fpm 服务的 URL，下面我们会具体说明。
- /www/ : 是 myphp-fpm 中 php 文件的存储路径，映射到本地的 ~/nginx/www 目录。
启动 nginx：
docker run --name runoob-php-nginx -p 8083:80 -d \ -v ~/nginx/www:/usr/share/nginx/html:ro \ -v ~/nginx/conf/conf.d:/etc/nginx/conf.d:ro \ --link myphp-fpm:php \ nginx
- -p 8083:80 : 端口映射，把 nginx 中的 80 映射到本地的 8083 端口。
- ~/nginx/www : 是本地 html 文件的存储目录，/usr/share/nginx/html 是容器内 html 文件的存储目录。
- ~/nginx/conf/conf.d : 是本地 nginx 配置文件的存储目录，/etc/nginx/conf.d 是容器内 nginx 配置文件的存储目录。
- –link myphp-fpm:php : 把 myphp-fpm 的网络并入 nginx ，并通过修改 nginx 的 /etc/hosts，把域名 php 映射成 127.0.0.1，让 nginx 通过 php:9000 访问 php-fpm。
接下来我们在 ~/nginx/www 目录下创建 index.php，代码如下：
<?phpecho phpinfo();?>
浏览器打开 ，显示如下：

runoob@runoob:~/python$ docker images python:3.5 REPOSITORY TAG IMAGE ID CREATED SIZEpython 3.5 045767ddf24a 9 days ago 684.1 MB
使用python镜像
在~/python/myapp目录下创建一个 helloworld.py 文件，代码如下：
#!/usr/bin/pythonprint("Hello, World!");
运行容器
runoob@runoob:~/python$ docker run -v $PWD/myapp:/usr/src/myapp -w /usr/src/myapp python:3.5 python helloworld.py
命令说明：
-v $PWD/myapp:/usr/src/myapp : 将主机中当前目录下的myapp挂载到容器的/usr/src/myapp
-w /usr/src/myapp : 指定容器的/usr/src/myapp目录为工作目录
python helloworld.py : 使用容器的python命令来执行工作目录中的helloworld.py文件
输出结果：
Hello, World!
Docker 安装 redis
方法一、docker pull redis:3.2
查找Docker Hub上的redis镜像
runoob@runoob:~/redis$ docker search redisNAME DESCRIPTION STARS OFFICIAL AUTOMATEDredis Redis is an open source ... 2321 [OK] sameersbn/redis 32 [OK]torusware/speedus-redis Always updated official ... 29 [OK]bitnami/redis Bitnami Redis Docker Image 22 [OK]anapsix/redis 11MB Redis server image ... 6 [OK]webhippie/redis Docker images for redis 4 [OK]clue/redis-benchmark A minimal docker image t... 3 [OK]williamyeh/redis Redis image for Docker 3 [OK]unblibraries/redis Leverages phusion/baseim... 2 [OK]greytip/redis redis 3.0.3 1 [OK]servivum/redis Redis Docker Image 1 [OK]...
这里我们拉取官方的镜像,标签为3.2
runoob@runoob:~/redis$ docker pull redis:3.2
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为redis,标签为3.2的镜像。
runoob@runoob:~/redis$ docker images redis REPOSITORY TAG IMAGE ID CREATED SIZEredis 3.2 43c923d57784 2 weeks ago 193.9 MB
方法二、通过 Dockerfile 构建
创建Dockerfile
首先，创建目录redis,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/redis ~/redis/data
data目录将映射为redis容器配置的/data目录,作为redis数据持久化的存储目录
进入创建的redis目录，创建Dockerfile

通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/redis$ docker build -t redis:3.2 .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/redis$ docker images redis REPOSITORY TAG IMAGE ID CREATED SIZEredis 3.2 43c923d57784 2 weeks ago 193.9 MB
使用redis镜像
运行容器
runoob@runoob:~/redis$ docker run -p 6379:6379 -v $PWD/data:/data -d redis:3.2 redis-server --appendonly yes43f7a65ec7f8bd64eb1c5d82bc4fb60e5eb31915979c4e7821759aac3b62f330runoob@runoob:~/redis$
命令说明：
-p 6379:6379 : 将容器的6379端口映射到主机的6379端口
-v $PWD/data:/data : 将主机中当前目录下的data挂载到容器的/data
redis-server –appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置
查看容器启动情况

连接、查看容器
使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1

Docker 安装 Apache
方法一、docker pull httpd
查找Docker Hub上的httpd镜像

这里我们拉取官方的镜像
runoob@runoob:~/apache$ docker pull httpd
等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为httpd的镜像。

方法二、通过 Dockerfile构建
创建Dockerfile
首先，创建目录apache,用于存放后面的相关东西。
runoob@runoob:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf
www目录将映射为apache容器配置的应用程序目录
logs目录将映射为apache容器的日志目录
conf目录里的配置文件将映射为apache容器的配置文件
进入创建的apache目录，创建Dockerfile
FROM debian:jessie# add our user and group first to make sure their IDs get assigned consistently, regardless of whatever dependencies get added#RUN groupadd -r www-data && useradd -r --create-home -g www-data www-dataENV HTTPD_PREFIX /usr/local/apache2ENV PATH $PATH:$HTTPD_PREFIX/binRUN mkdir -p "$HTTPD_PREFIX" \ && chown www-data:www-data "$HTTPD_PREFIX"WORKDIR $HTTPD_PREFIX# install httpd runtime dependencies# #requirementsRUN apt-get update \ && apt-get install -y --no-install-recommends \ libapr1 \ libaprutil1 \ libaprutil1-ldap \ libapr1-dev \ libaprutil1-dev \ libpcre++0 \ libssl1.0.0 \ && rm -r /var/lib/apt/lists/*ENV HTTPD_VERSION 2.4.20ENV HTTPD_BZ2_URL RUN buildDeps=' \ ca-certificates \ curl \ bzip2 \ gcc \ libpcre++-dev \ libssl-dev \ make \ ' \ set -x \ && apt-get update \ && apt-get install -y --no-install-recommends $buildDeps \ && rm -r /var/lib/apt/lists/* \ \ && curl -fSL "$HTTPD_BZ2_URL" -o httpd.tar.bz2 \ && curl -fSL "$HTTPD_BZ2_URL.asc" -o httpd.tar.bz2.asc \# see #verify && export GNUPGHOME="$(mktemp -d)" \ && gpg --keyserver ha.pool.sks-keyservers.net --recv-keys A93D62ECC3C8EA12DB220EC934EA76E6791485A8 \ && gpg --batch --verify httpd.tar.bz2.asc httpd.tar.bz2 \ && rm -r "$GNUPGHOME" httpd.tar.bz2.asc \ \ && mkdir -p src \ && tar -xvf httpd.tar.bz2 -C src --strip-components=1 \ && rm httpd.tar.bz2 \ && cd src \ \ && ./configure \ --prefix="$HTTPD_PREFIX" \ --enable-mods-shared=reallyall \ && make -j"$(nproc)" \ && make install \ \ && cd .. \ && rm -r src \ \ && sed -ri \ -e 's!^(\s*CustomLog)\s+\S+!\1 /proc/self/fd/1!g' \ -e 's!^(\s*ErrorLog)\s+\S+!\1 /proc/self/fd/2!g' \ "$HTTPD_PREFIX/conf/httpd.conf" \ \ && apt-get purge -y --auto-remove $buildDepsCOPY httpd-foreground /usr/local/bin/EXPOSE 80CMD ["httpd-foreground"]
Dockerfile文件中 COPY httpd-foreground /usr/local/bin/ 是将当前目录下的httpd-foreground拷贝到镜像里，作为httpd服务的启动脚本，所以我们要在本地创建一个脚本文件httpd-foreground
#!/bin/bashset -e# Apache gets grumpy about PID files pre-existingrm -f /usr/local/apache2/logs/httpd.pidexec httpd -DFOREGROUND
赋予httpd-foreground文件可执行权限
runoob@runoob:~/apache$ chmod +x httpd-foreground
通过Dockerfile创建一个镜像，替换成你自己的名字
runoob@runoob:~/apache$ docker build -t httpd .
创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
runoob@runoob:~/apache$ docker images httpdREPOSITORY TAG IMAGE ID CREATED SIZEhttpd latest da1536b4ef14 23 seconds ago 195.1 MB
使用apache镜像
运行容器
docker run -p 80:80 -v $PWD/www/:/usr/local/apache2/htdocs/ -v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf -v $PWD/logs/:/usr/local/apache2/logs/ -d httpd
命令说明：
-p 80:80 : 将容器的80端口映射到主机的80端口
-v $PWD/www/:/usr/local/apache2/htdocs/ : 将主机中当前目录下的www目录挂载到容器的/usr/local/apache2/htdocs/
-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf : 将主机中当前目录下的conf/httpd.conf文件挂载到容器的/usr/local/apache2/conf/httpd.conf
-v $PWD/logs/:/usr/local/apache2/logs/ : 将主机中当前目录下的logs目录挂载到容器的/usr/local/apache2/logs/
