Docker 安装 Apache

方法一、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。

root@web3:~$ 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

# https://httpd.apache.org/docs/2.4/install.html#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 https://www.apache.org/dist/httpd/httpd-$HTTPD_VERSION.tar.bz2

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 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 $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

root@web3:~/apache$ chmod +x httpd-foreground

通过Dockerfile创建一个镜像，替换成你自己的名字

root@web3:~/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

root@web3:~/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

root@web3:~/apache$ docker search httpd

...

这里我们拉取官方的镜像

root@web3:~/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
