# Steps used September 2021 to get Zoneminder working on Ubuntu 18.04 with a 
# Reolink RLC-410W camera.


# Install dependencies:
sudo apt-get install tasksel
sudo tasksel install lamp-server


# Add repo and install Zoneminder itself:
# sudo add-apt-repository ppa:iconnor/zoneminder-1.34
# NOTE: The above version could detect camera, but not streaming profiles, 
# making camera setup impossible. This appears to be a relatively common issue: 
# <https://forums.zoneminder.com/viewtopic.php?t=28922>
sudo add-apt-repository ppa:iconnor/zoneminder-1.36
sudo apt update
sudo apt install zoneminder


# REVIEW: Optional?
# Change some permissions to its config/data directories: 
sudo chmod 740 /etc/zm/zm.conf
sudo chown root:www-data /etc/zm/zm.conf
sudo chown -R www-data:www-data /usr/share/zoneminder/


# Configure and reload Apache server:
sudo a2enmod cgi
sudo a2enmod rewrite
sudo a2enconf zoneminder


# Edit time zone in `/etc/php/7.2/apache2/php.ini`:
# (Time zone formatting examples: 
#  <https://www.php.net/manual/en/timezones.php>)
# 
#     [Date]
#     ; Defines the default timezone used by the date functions
#     ; http://php.net/date.timezone
#     date.timezone = America/New_York


# Reload Apache:
sudo systemctl reload apache2


# Actually start Zoneminder:
sudo systemctl enable zoneminder
sudo systemctl start zoneminder


# In the browser, open:
