Docker 安装 Apache

方法一、docker pull httpd

查找 Docker Hub 上的 httpd 镜像:

可以通过 Sort by 查看其他版本的 httpd，默认是最新版本 httpd:latest。

此外，我们还可以用 docker search httpd 命令来查看可用版本：

runoob@runoob:~/apache$ docker search httpd

...

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 httpd

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-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

&& 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

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
