linux – 在docker文件中编辑conf文件

概述我已经搜索了一段时间没有运气.我是 linux的初学者,一直在玩docker. 我需要编辑/etc/apache2/apache2.conf,以便将Directory / var / www /上的Allow覆盖设置为all not none. 所以从这个： <Directory /var/www/> Options Indexes FollowSymLinks AllowOver 我已经搜索了一段时间没有运气.我是 linux的初学者,一直在玩docker.

我需要编辑/etc/apache2/apache2.conf,以便将Directory / var / www /上的Allow覆盖设置为all not none.

所以从这个：

<Directory /var/www/>    Options Indexes FollowSymlinks    AllowOverrIDe **none**    Require all granted</Directory>

对此：

<Directory /var/www/>    Options Indexes FollowSymlinks    AllowOverrIDe **All**    Require all granted</Directory>

我无法弄清楚如何用新块替换旧的文本块,AllowOverrIDe在conf文件中出现几次.

我需要能够从bash提示符运行命令,任何帮助将不胜感激.

完整的apache con文件：

{# 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 the#   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 not#   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!

解决方法 我在这个问题中找到了答案：
https://superuser.com/questions/645799/using-sed-to-enable-htaccess-files-in-apache-config

只需使用sed(流编辑器)命令编辑文件即可.

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

-i选项指定’inplace’编辑,它告诉sed写在同一文件的顶部.

要在映像构建时仅在/ var / www部分中将AllowOverrIDe更改为All,请将以下命令添加到Dockerfile：

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