Docker 安装 Apache
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
REPOSITORY TAG IMAGE ID CREATED SIZE
httpd latest da1536b4ef14 23 seconds ago 195.1 MB
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 $HTTPD_PREFIX
# install httpd runtime dependencies
# https://httpd.apache.org/docs/2.4/install.html#requirements
RUN apt-get update
&& apt-get install -y --no-install-recommends
libapr1
libaprutil1
libaprutil1-ldap
libapr1-dev
libaprutil1-dev
libpcre++0
libssl1.0.0
&& rm -r /var/lib/apt/lists/*
ENV HTTPD_VERSION 2.4.20
ENV HTTPD_BZ2_URL https://www.apache.org/dist/httpd/httpd-$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 $buildDeps
COPY httpd-foreground /usr/local/bin/
EXPOSE 80
CMD ["httpd-foreground"]
Dockerfile文件中 COPY httpd-foreground /usr/local/bin/ 是将当前目录下的httpd-foreground拷贝到镜像里，作为httpd服务的启动脚本，所以我们要在本地创建一个脚本文件httpd-foreground
#!/bin/bash
set -e
# Apache gets grumpy about PID files pre-existing
rm -f /usr/local/apache2/logs/httpd.pid
exec httpd -DFOREGROUND
赋予 httpd-foreground 文件可执行权限。
runoob@runoob:~/apache$ 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
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
