Docker 入门教程 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。

w3cschool@w3cschool:~$ 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

w3cschool@w3cschool:~/apache$ chmod +x httpd-foreground

通过Dockerfile创建一个镜像,替换成你自己的名字

w3cschool@w3cschool:~/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

w3cschool@w3cschool:~/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

w3cschool@w3cschool:~/apache$ docker search httpd
NAME DESCRIPTION STARS OFFICIAL AUTOMATED

...

这里我们拉取官方的镜像

w3cschool@w3cschool:~/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

w3cschool@w3cschool:~/apache$ docker ps
CONTAINER ID IMAGE COMMAND ... PORTS NAMES
79a97f2aac37 httpd "httpd-foreground" ... 0.0.0.0:80->80/tcp sharp_swanson
