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
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

&& 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
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
