2.28. Docker install Apache

2.28.1. Method 1. Docker pull httpd ¶

Find Docker Hub Httpd image on:

` <../wp-content/uploads/2016/06/DD4D706F-7D45-41F6-9506-069E12A87F9D.jpg>` __

You can view other versions of httpd through Sort by. The default is the latest version. httpd:latest .

In addition, we can use the docker search httpd command to view the available versions:

runoob@runoob:~/apache$ docker search httpd NAME DESCRIPTION STARS OFFICIAL AUTOMATED httpd The Apache HTTP Server .. 524 [OK] centos/httpd 7 [OK] rgielen/httpd-image-php5 Docker image for Apache... 1 [OK] microwebapps/httpd-frontend 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/httpd-image-simple Docker image for simple... 0 [OK] solsson/httpd Derivatives of the offi... 0 [OK] rgielen/httpd-image-drush Apache HTTPD + Drupal S... 0 [OK] learninglayers/httpd 0 [OK] sohrabkhan/httpd Docker httpd + php5.6 (... 0 [OK] aintohvri/docker-httpd Apache HTTPD Docker ext... 0 [OK] alizarion/httpd httpd on centos with mo... 0 [OK] ... 

Here we pull the official image.

runoob@runoob:~/apache$ docker pull httpd

After waiting for the download to complete, we can look up the image whose REPOSITORY is httpd in the list of local images.

2.28.2. Method 2. Build through Dockerfile ¶

创建 Dockerfile

First, create the directory apache, which will be used to store the following related things.

runoob@runoob:~$ mkdir -p ~/apache/www ~/apache/logs ~/apache/conf

The www directory will be mapped to the application directory configured by the apache container.

The logs directory is mapped to the log directory of the apache container.

The configuration file in the conf directory will be mapped to the configuration file of the apache container.

Go to the apache directory you created and create the 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"] 

COPY httpd-foreground / usr/local/bin/ in the Dockerfile file copies the httpd-foreground in the current directory to the image as the startup script for the httpd service, so we need to create a script file httpd-foreground locally

#!/bin/bash set -e # Apache gets grumpy about PID files pre-existing rm -f /usr/local/apache2/logs/httpd.pid exec httpd -DFOREGROUND 

Give executable permissions to the httpd-foreground file.

runoob@runoob:~/apache$ chmod +x httpd-foreground

Create an image through Dockerfile and replace it with your own name.

runoob@runoob:~/apache$ docker build -t httpd .

After the creation is completed, we can find the image we just created in the local image list.

runoob@runoob:~/apache$ docker images httpd REPOSITORY TAG IMAGE ID CREATED SIZE httpd latest da1536b4ef14 23 seconds ago 195.1 MB 

Use apache mirroring ¶

2.28.3. Run the container ¶

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 

Command description:

-p 80:80: Map port 80 of the container to port 80 of the host.

-v $PWD/www/:/usr/local/apache2/htdocs/: Mount the www directory under the current directory on the host to the / usr/local/apache2/htdocs/ of the container.

-v $PWD/conf/httpd.conf:/usr/local/apache2/conf/httpd.conf: Mount the conf/httpd.conf file in the current directory on the host to the / usr/local/apache2/conf/httpd.conf of the container.

-v $PWD/logs/:/usr/local/apache2/logs/: Mount the logs directory under the current directory on the host to the / usr/local/apache2/logs/ of the container.

Check the container startup:

runoob@runoob:~/apache$ docker ps CONTAINER ID IMAGE COMMAND ... PORTS NAMES 79a97f2aac37 httpd "httpd-foreground" ... 0.0.0.0:80->80/tcp sharp_swanson
