Serverinstallation Linux

The following steps describe how to install on a Debian 10 server. Generally you can try to install on other Linux systems.

This may work if all Squeeze dependencies like the correct PHP version, PHP modules and Apache extensions are present in your operating systems package repositories.

Linux (Debian 10)

1. Prepare Debian for installation via apt

Before installing Squeeze some third party applications need to be installed. Follow the steps below to install these applications.

Please note that using a proxy to connect to the internet might need some additional configuration like:

export https_proxy=https://proxy.intra.net:proxy_port
or
export http_proxy=http://user:password@proxy.intra.net:proxy_port

apt update
apt upgrade

2. Install PHP 7.4

apt-get update
apt-get install php7.4 php7.4-cli php7.4-common php7.4-imap php7.4-mysql php7.4-mailparse php7.4-bcmath php7.4-intl php7.4-gd php7.4-xml php7.4-xsl php7.4-mbstring php7.4-opcache php7.4-curl php7.4-zip php7.4-bz2 php7.4-soap php7.4-json php7.4-imagick libapache2-mod-php7.4

3. Install Apache

To install Apache run the following command

apt install apache2

And enable the following modules

a2enmod proxy rewrite deflate filter headers

4. Install MariaDB

apt update
apt install mariadb-server
systemctl status mariadb

run the follwing command and follow the instructions to secure the installation:

mysql_secure_installation

Create a new user for later use

mysql --user=root mysql

CREATE USER 'squeeze'@'localhost' IDENTIFIED BY 'secret';
GRANT ALL PRIVILEGES ON *.* TO 'squeeze'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

5. Install RabbitMQ

Run the following command to install RabbitMQ including the management web interface

apt-get install rabbitmq-server
rabbitmq-plugins enable rabbitmq_management

If needed add a new user to RabbitMQ

rabbitmqctl add_user username password
rabbitmqctl set_user_tags username administrator
rabbitmqctl set_permissions -p / username ".*" ".*" ".*"

6. Install ElasticSearch

Run the following command to install ElasticSearch

nano /etc/apt/sources.list
deb http://ftp.us.debian.org/debian sid main

apt-get update
apt install openjdk-8-jre-headless

apt install gnupg2
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | apt-key add -
echo "deb https://artifacts.elastic.co/packages/5.x/apt stable main" | tee -a /etc/apt/sources.list.d/elastic-5.x.list
apt update && apt upgrade
apt install apt-transport-https uuid-runtime pwgen
apt update
apt install elasticsearch

cd /usr/share/elasticsearch/bin 
./elasticsearch-plugin install analysis-icu
./elasticsearch-plugin install mapper-attachments

To be able to install the plugins behind a proxy please use the following commands:

ES_JAVA_OPTS="-Dhttp.proxyHost=proxy.intra.net -Dhttp.proxyPort=3128 -Dhttps.proxyHost=proxy.intra.net -Dhttps.proxyPort=3128" ./elasticsearch-plugin install analysis-icu 
ES_JAVA_OPTS="-Dhttp.proxyHost=proxy.intra.net -Dhttp.proxyPort=3128 -Dhttps.proxyHost=proxy.intra.net -Dhttps.proxyPort=3128" ./elasticsearch-plugin install mapper-attachments

Optional:

nano /etc/elasticsearch/elasticsearch.yml
cluster.name: my-applicationnano 

/etc/elasticsearch/jvm.options
-Xms512m
-Xmx512m

Enable and start ElasticSearch

systemctl daemon-reload
systemctl enable elasticsearch.service
systemctl restart elasticsearch.service
systemctl status elasticsearch.service

apt install tesseract-ocr tesseract-ocr-deu imagemagick ghostscript poppler-utils zbar-tools git sudo

8. Install Squeeze

cd /var/www/html
git clone https://git.dexpro-solutions.de/dex/squeeze/Squeeze.git

<Directory "/var/www/html/Squeeze/public">
    AllowOverride All
</Directory>

Now restart the apache webserver:

systemctl restart apache2
