本文介绍两种在Docker中搭建Apache服务的方法：一是直接从DockerHub拉取httpd镜像；二是通过自定义Dockerfile构建镜像，详细解释了Dockerfile各项指令含义，并演示如何创建和运行容器。

方法一、docker pull httpd

查找Docker Hub上的httpd镜像

runoob@runoob:~/apache$ docker search httpdNAME DESCRIPTION STARS OFFICIAL AUTOMATEDhttpd The Apache HTTP Server .. 524 [OK] centos/httpd 7 [OK]rgielen/httpd-image-php5 Docker image for Apache... 1 [OK]microwebapps/httpd-frontend Httpd frontend allowing... 1 [OK]lolhens/httpd Apache httpd 2 Server 1 [OK]publici/httpd httpd:latest 0 [OK]publicisworldwide/httpd The Apache httpd webser... 0 [OK]rgielen/httpd-image-simple Docker image for simple... 0 [OK]solsson/httpd Derivatives of the offi... 0 [OK]rgielen/httpd-image-drush Apache HTTPD + Drupal S... 0 [OK]learninglayers/httpd 0 [OK]sohrabkhan/httpd Docker httpd + php5.6 (... 0 [OK]aintohvri/docker-httpd Apache HTTPD Docker ext... 0 [OK]alizarion/httpd httpd on centos with mo... 0 [OK]...

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。

runoob@runoob:~/apache$ docker images httpdREPOSITORY TAG IMAGE ID CREATED SIZEhttpd latest da1536b4ef14 23 seconds ago 195.1 MB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 $HTTPD_PREFIX# install httpd runtime dependencies# https://httpd.apache.org/docs/2.4/install.html#requirementsRUN apt-get update \ && apt-get install -y --no-install-recommends \ libapr1 \ libaprutil1 \ libaprutil1-ldap \ libapr1-dev \ libaprutil1-dev \ libpcre++0 \ libssl1.0.0 \ && rm -r /var/lib/apt/lists/*ENV HTTPD_VERSION 2.4.20ENV HTTPD_BZ2_URL https://www.apache.org/dist/httpd/httpd-$HTTPD_VERSION.tar.bz2RUN 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 "$HTTPD_BZ2_URL.asc" -o httpd.tar.bz2.asc \# see https://httpd.apache.org/download.cgi#verify && export GNUPGHOME="$(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/

查看容器启动情况

runoob@runoob:~/apache$ docker psCONTAINER ID IMAGE COMMAND ... PORTS NAMES79a97f2aac37 httpd "httpd-foreground" ... 0.0.0.0:80->80/tcp sharp_swanson
