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。

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-dataENV HTTPD_PREFIX /usr/local/apache2 ENV PATH $PATH:$HTTPD_PREFIX/bin RUN mkdir p “$HTTPD_PREFIX” / && chown wwwdata:wwwdata “$HTTPD_PREFIX”WORKDIR $HTTPD_PREFIX# install httpd runtime dependencies# https://httpd.apache.org/docs/2.4/install.html#requirementsRUN aptget update / && aptget install y noinstallrecommends / libapr1 / libaprutil1 / libaprutil1ldap / libapr1dev / libaprutil1dev / libpcre++0 / libssl1.0.0 / && rm r /var/lib/apt/lists/* ENV HTTPD_VERSION 2.4.20 ENV HTTPD_BZ2_URL https://www.apache.org/dist/httpd/httpd-$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/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

runoob@runoob:~/apache$ chmod +x httpdforeground

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


方法二、docker pull httpd

查找Docker Hub上的httpd镜像

runoob@runoob:~/apache$ docker search httpd NAME                           DESCRIPTION                  STARS  OFFICIAL AUTOMATED httpd                          The Apache HTTP Server ..    524     [OK]       centos/httpd                                                7                [OK]rgielen/httpdimagephp5       Docker image for Apache   1                [OK]microwebapps/httpdfrontend    Httpd frontend allowing   1                [OK]lolhens/httpd                  Apache httpd 2 Server        1                [OK]publici/httpd                  httpd:latest                 0                [OK]publicisworldwide/httpd        The Apache httpd webser   0                [OK]rgielen/httpdimagesimple     Docker image for simple   0                [OK]solsson/httpd                  Derivatives of the offi   0                [OK]rgielen/httpdimagedrush      Apache HTTPD + Drupal S   0                [OK]learninglayers/httpd                                        0                [OK]sohrabkhan/httpd               Docker httpd + php5.6 (…   0                [OK]aintohvri/dockerhttpd         Apache HTTPD Docker ext   0                [OK]alizarion/httpd                httpd on centos with mo   0                [OK]

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。


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               NAMES79a97f2aac37  httpd   “httpd-foreground”   0.0.0.0:80->80/tcp  sharp_swanson
