Docker 安装 Apache

方式一、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

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

    \
    && 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' \

    \
    && 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/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

chmod +x httpd-foreground

通过Dockerfile创建一个镜像，替换成自己的名字

docker build -t httpd .

创建完成后，可以在本地的镜像列表中查找到刚刚创建的镜像

docker images httpd

方法二、docker pull httpd

查找Docker Hub上的Httpd镜像

docker search httpd

这里拉取官方的镜像

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

-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

docker ps
