问题描述:

I have searched for a while with no luck. I am very much a beginner with linux and have been playing around with docker.

I need to edit /etc/apache2/apache2.conf so that Allow override on Directory /var/www/ is set to all not none.

So from this:

<Directory /var/www/>

Options Indexes FollowSymLinks

AllowOverride **none**

Require all granted

</Directory>

To this:

<Directory /var/www/>

Options Indexes FollowSymLinks

AllowOverride **All**

Require all granted

</Directory>

I cant figure out how to replace the old block of text with the new block, AllowOverride appears a few times in the conf file.

I would need to be able to run the command from bash prompt, any help would be appreciated.

{# This is the main Apache server configuration file. It contains the

# configuration directives that give the server its instructions.

# See http://httpd.apache.org/docs/2.4/ for detailed information about

# the directives and /usr/share/doc/apache2/README.Debian about Debian specific

# hints.

#

#

# Summary of how the Apache 2 configuration works in Debian:

# The Apache 2 web server configuration in Debian is quite different to

# upstream's suggested way to configure the web server. This is because Debian'

s

# default Apache2 installation attempts to make adding and removing modules,

# virtual hosts, and extra configuration directives as flexible as possible, in

# order to make automating the changes and administering the server as easy as

# possible.

# It is split into several files forming the configuration hierarchy outlined

# below, all located in the /etc/apache2/ directory:

#

# /etc/apache2/

# |-- apache2.conf

# | `-- ports.conf

# |-- mods-enabled

# | |-- *.load

# | `-- *.conf

# |-- conf-enabled

# | `-- *.conf

# `-- sites-enabled

# `-- *.conf

#

#

# * apache2.conf is the main configuration file (this file). It puts the pieces

# together by including all remaining configuration files when starting up th

e

# web server.

#

# * ports.conf is always included from the main configuration file. It is

# supposed to determine listening ports for incoming connections which can be

# customized anytime.

#

# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/

# directories contain particular configuration snippets which manage modules,

# global configuration fragments, or virtual host configurations,

# respectively.

#

# They are activated by symlinking available configuration files from their

# respective *-available/ counterparts. These should be managed by using our

# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See

# their respective man pages for detailed information.

#

# * The binary is called apache2. Due to the use of environment variables, in

# the default configuration, apache2 needs to be started/stopped with

# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will n

ot

# work with the default configuration.

# Global configuration

#

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# NOTE! If you intend to place this on an NFS (or otherwise network)

# mounted filesystem then please read the Mutex documentation (available

# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);

# you will save yourself a lot of trouble.

#

# Do NOT add a slash at the end of the directory path.

# identification number when it starts.

# This needs to be set in /etc/apache2/envvars

#

# Timeout: The number of seconds before receives and sends time out.

#

Timeout 300

#

# KeepAlive: Whether or not to allow persistent connections (more than

# one request per connection). Set to "Off" to deactivate.

#

# MaxKeepAliveRequests: The maximum number of requests to allow

# during a persistent connection. Set to 0 to allow an unlimited amount.

# We recommend you leave this number high, for maximum performance.

# HostnameLookups: Log the names of clients or just their IP addresses

# e.g., www.apache.org (on) or 204.62.129.132 (off).

# The default is off because it'd be overall better for the net if people

# had to knowingly turn this feature on, since enabling it means that

# each client request will result in AT LEAST one lookup request to the

# nameserver.

# ErrorLog: The location of the error log file.

# If you do not specify an ErrorLog directive within a <VirtualHost>

# container, error messages relating to that virtual host will be

# logged here. If you *do* define an error logfile for a <VirtualHost>

# container, that host's errors will be logged there and not here.

#

ErrorLog ${APACHE_LOG_DIR}/error.log

#

# LogLevel: Control the severity of messages logged to the error_log.

# Available values: trace8, ..., trace1, debug, info, notice, warn,

# error, crit, alert, emerg.

# It is also possible to configure the log level for particular modules, e.g.

# "LogLevel info ssl:warn"

# Sets the default security model of the Apache2 HTTPD server. It does

# The former is used by web applications packaged in Debian,

# your system is serving content from a sub-directory in /srv you must allow

# access here, or in any related virtual host.

I found the answer in this question: https://superuser.com/questions/645799/using-sed-to-enable-htaccess-files-in-apache-config

Simply use the sed (stream editor) command to edit the file.

sed -i '/startpattern/endpattern/ <sed-commands>' file

The -i option specifies 'inplace' editing, which tells sed to write over the top of the same file.

To change AllowOverride to All only within the /var/www section upon image build, add the following command to your Dockerfile:

RUN sed -i '/<Directory \/var\/www\/>/,/<\/Directory>/ s/AllowOverride None/AllowOverride All/' /etc/apache2/apache2.conf
