Apache HTTP: установка mod_dispatcher для Adobe Experience Manager

Автор: | 12/11/2015
 

apache_logoDispatcher — еще одна часть  AEM, предназначенная для кеширования и в качестве балансировщика нагрузки.

Является отдельным модулем, имеются версии для Apache HTTP 2.2, 2.4, MS IIS и других серверов.

В данном примере установка будет выполняться на Vagrant + Ubuntu 14.04 + Apache 2.2. 

Подготовка

Создаем каталог для Vagrant-бокса:

$ mkdir ~/VMs/Vagrant/AEM_Dispatcher
$ cd ~/VMs/Vagrant/AEM_Dispatcher

Инициализируем Vagrantfile:

$ vagrant init ubuntu/trusty64

Устанавливаем память и порты:

...
config.vm.network "forwarded_port", guest: 80, host: 8080
...
  config.vm.provider "virtualbox" do |vb|
     vb.memory = "2048"
  end
...

Запускаем и подключаемся:

$ vagrant up&& vagrant ssh

Устанавливаем Apache HTTP:

# apt-get update && apt-get -y install apache2

Проверяем:

# apache2 -v
Server version: Apache/2.4.7 (Ubuntu)
Server built:   Oct 14 2015 14:20:21
# service apache2 status
 * apache2 is running
# curl localhost; echo $?
...
0

Установка Dispatcher

Загружаем подходящий архив отсюда>>>:

# cd /tmp/
# wget https://www.adobeaemcloud.com/content/companies/public/adobe/dispatcher/dispatcher/_jcr_content/top/download_10/file.res/dispatcher-apache2.4-linux-x86-64-4.1.11.tar.gz

Распаковываем:

# tar xfp dispatcher-apache2.4-linux-x86-64-4.1.11.tar.gz
# ls -l
total 920
drwxr-xr-x 2  501 games   4096 Oct 15 09:51 conf
-rwxr-xr-x 1  501 games 644021 Oct 22 15:38 dispatcher-apache2.4-4.1.11.so
-rw-r--r-- 1 root root  275378 Nov  3 18:42 dispatcher-apache2.4-linux-x86-64-4.1.11.tar.gz
-rw-r--r-- 1  501 games   3827 Oct  6 11:47 license.txt
-rw-r--r-- 1  501 games   7357 Oct 22 15:19 release-notes.txt

Тут же есть готовые примеры файлов конфигурации:

# ls -l conf/
total 68
-rw-r--r-- 1 501 games  6314 Oct  6 11:47 README.dispatcher.apache2
-rw-r--r-- 1 501 games  6649 Oct  6 11:47 author_dispatcher.any
-rw-r--r-- 1 501 games  9420 Oct 15 09:51 dispatcher.any
-rw-r--r-- 1 501 games 37488 Oct  6 11:47 httpd.conf.disp2

Файл dispatcher-apache2.4-4.1.11.so — разделяемая библиотека, которую добавляем в Apache:

# cp dispatcher-apache2.4-4.1.11.so /usr/lib/apache2/modules

Создаем каталог (или укажите свой путь в параметре DispatcherConfig, до него дойдем позже):

# mkdir /etc/apache2/conf

Копируем файл конфигурации:

# cp conf/dispatcher.any /etc/apache2/conf

Добавляем файл /etc/apache2/mods-enabled/dispatcher.load:

LoadModule dispatcher_module /usr/lib/apache2/modules/mod_dispatcher.so

Проверяем:

# apachectl -t
...
Syntax OK

Добавляем в /etc/apache2/mods-enabled/dispatcher.load настройки Dispatcher:

<IfModule disp_apache2.c>
  DispatcherConfig conf/dispatcher.any
  DispatcherLog    /var/logs/dispatcher.log
  DispatcherLogLevel 3
  DispatcherNoServerHeader 0
  DispatcherDeclineRoot 0
  DispatcherUseProcessedURL 0
  DispatcherPassError 0
</IfModule>

Редактируем файл /etc/apache2/sites-enabled/000-default.conf в котором описывает обработчик dispatcher-handler для виртуалхоста:

<VirtualHost *:80>

        DocumentRoot /var/www/aemcache

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <Directory /var/www/aemcache>
            <IfModule disp_apache2.c>
                SetHandler dispatcher-handler
                ModMimeUsePathInfo On
            </IfModule>
            AllowOverride None
        </Directory>

</VirtualHost>

Создаем директорию:

# mkdir /var/www/aemcache && chown www-data:www-data /var/www/aemcache

Перезагружаем Apache:

# service apache2 restart
 * Restarting web server apache2
# service apache2 status
 * apache2 is running

Готово.

Далее остается настроить RewriteRule-ы.

Пример конфига с боевого сервера:

<VirtualHost *:80>
    <ifModule mod_rewrite.c>
        RewriteEngine on
        RewriteRule   ^(.*)$  https://%{HTTP_HOST}$1 [R=301]
    </ifModule>
</VirtualHost>

<VirtualHost *:443>

    <IfModule mod_ssl.c>
        SSLEngine on
        SSLProtocol all -SSLv2
        SSLCertificateFile    /etc/ssl/certs/host.crt
        SSLCertificateKeyFile /etc/ssl/private/host.key
        SSLCertificateChainFile /etc/ssl/certs/rootCA.crt
    </IfModule>
