方法一、通过 Docker file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-data
ENV HTTPD_PREFIX /usr/local/apache2
ENV PATH $PATH:$HTTPD_PREFIX/bin
RUN mkdir -p "$HTTPD_PREFIX" \
 && chown www-data:www-data "$HTTPD_PREFIX"
WORKDIR $HTTPD_PREFIX
# install  httpd  runtime dependencies
# #requirements
RUN 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 2.4.20
ENV 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 $buildDeps
COPY httpd-foreground /usr/local/bin/
EXPOSE 80
CMD ["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/bash
set -e
# Apache gets grumpy about PID files pre-existing
rm -f /usr/local/apache2/logs/httpd.pid
exec 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 httpd
REPOSITORY TAG IMAGE ID CREATED SIZE
httpd latest da1536b4ef14 23 seconds ago 195.1 MB 

方法二、docker pull httpd

查找Docker Hub上的httpd镜像

runoob@runoob:~/apache$ docker search httpd

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。

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 ps
CONTAINER ID IMAGE COMMAND ... PORTS NAMES
79a97f2aac37 httpd "httpd-foreground" ... 0.0.0.0:80->80/tcp sharp_swanson
