Install OS4X on Ubuntu 20
General
Ubuntu 20.x is supported by the automatic OS4X installer since build 2016-11-24. Older versions lack the ability to support various features of this modern operating system.
Packages
You need the following packages to be installed:
apt-get install apache2 \ mysql-server \ libapache2-mod-php \ php-mysql \ php-xml \ xsltproc \ zip
Special installation parameter
When running the automated installer script, you will have to use "localhost" instead of "127.0.0.1" in the default MySQL installation (since the MySQL user "root" isn't allowed for 127.0.01, but for localhost). You'll get the following error otherwise:
error: 'Access denied for user 'root'@'localhost
Configuration
PHP
The PHP configuration must be extended in order to use big file uploads. Edit the configuration file
/etc/php/7.4/apache2/php.ini
and set these values:
upload_max_filesize = 128M post_max_size = 128M
Don't forget to restart Apache afterwards:
service apache2 restart
SystemD integration
Download the source tarball from https://cdn.c-works.de/fileadmin/downloads/os4x.systemd.tar, extract it /tmp. Then, copy over the files:
cp /tmp/etc/init.d/os4x /etc/init.d/ cp /tmp/etc/systemd/system/os4x.service /etc/systemd/system
Then, enable the service:
systemctl enable os4x systemctl start os4x
