incorrect redmine installation - apache

Question

I am trying to install redmine 3.2.0 like in the following article.
The point 2.4 Test Redmine works fine, i.e. I am able to open redmine using http://MY_IP:3000.
After this, I did:
sudo chown -R www-data files log tmp public/plugin_assets
sudo chmod -R 755 files log tmp public/plugin_assets
sudo ln -s /opt/redmine/redmine-3.2.2/public/ /var/www/html/redmine
Added Listen 89 into /etc/apache2/ports.conf.
Created the following sudo vim /etc/apache2/sites-available/redmine.conf:
<VirtualHost MY_IP:89>
ServerAdmin email#example
DocumentRoot /var/www/html/
<Location /redmine>
RailsEnv production
RackBaseURI /redmine
Options -MultiViews
</Location>
</VirtualHost>
Enabled redmine.conf: sudo a2ensite redmine.conf.
Added PassengerUser www-data into /etc/apache2/mods-available/passenger.conf. Now passenger.conf contains the following:
<IfModule mod_passenger.c>
PassengerRoot /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini
PassengerDefaultRuby /usr/bin/ruby
PassengerUser www-data
</IfModule>
And restarted apache: sudo service apache2 restart.
So /var/www/html/ contains:
drwxr-xr-x 2 root root 4096 Jan 25 09:32 .
drwxr-x--x 7 root root 4096 Jan 22 07:21 ..
-rw-r--r-- 1 root root 11104 Jan 22 02:57 index.html
lrwxrwxrwx 1 root root 34 Jan 25 09:32 redmine -> /opt/redmine/redmine-3.2.0/public/
Now if I am going to http://MY_IP:89 then /var/www/html/index.html is opened instead of redmine home page.
Could you please advise where I did an error?
Thanks in advance!
UPDATE:
If I use the following redmine.conf:
<VirtualHost MY_IP:89>
DocumentRoot /var/www/html/redmine
<Directory /var/www/html/redmine>
RailsBaseURI /
PassengerResolveSymlinksInDocumentRoot on
AllowOverride None
RailsEnv production
Options -MultiViews
</Directory>
</VirtualHost>
Redmine won't start, only shows index of (/var/www/html/redmine/).

Answer 1

I SOLVED THE ISSUE:
I did gem install passenger. And I use the following redmine.conf:
<VirtualHost MY_IP:89>
DocumentRoot /var/www/html/redmine
<Directory /var/www/html/redmine>
RailsBaseURI /
PassengerResolveSymlinksInDocumentRoot on
AllowOverride None
RailsEnv production
Options -MultiViews
</Directory>
</VirtualHost>

Answer 2

From passenger 5.2.0 which was released in January 2018 "PassengerResolveSymlinksInDocumentRoot on" is no longer supported
in your /etc/apache2/sites-available/xxx.conf
make the following changes:
# Not supported from passenger 5.2.0 on wards
# PassengerResolveSymlinksInDocumentRoot on
PassengerAppRoot /opt/redmine/redmine-3.2.0/public/

Answer 3

My redmine works on apache with this config.
LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p551/gems/passenger-5.0.21/buildout/apache2/mod_passenger.so
<IfModule mod_passenger.c>
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p551/gems/passenger-5.0.21
PassengerDefaultRuby /usr/local/rvm/gems/ruby-1.9.3-p551/wrappers/ruby
</IfModule>
<VirtualHost redmine.domain:80>
ServerName redmine.domain
ServerAlias redmine
DocumentRoot /opt/redmine/redmine-3.2.0/public/
<Directory /opt/redmine/redmine-3.2.0/public/>
# This relaxes Apache security settings.
AllowOverride all
# MultiViews must be turned off.
Options -MultiViews
allow from all
</Directory>
