Must setup the mysql database. Used the following steps

  • Set the root password with sudo emerge --config =dev-db/mysql-5.5.52
  • Create the database running mysql -u root -h localhost -p (Using username/password from etc/db_connection_data.yml
  mysql> create database davaz2;
  Query OK, 1 row affected (0.00 sec)

  mysql> grant all privileges on davaz2.* to davaz@localhost identified by 'top-secret';
  Query OK, 0 rows affected (0.00 sec)

  mysql> flush privileges;
  Query OK, 0 rows affected (0.00 sec)

Now after restarting the davaz.com I see in the errorlog DRb::DRbConnError - drbssl://localhost:9997, which means it cannot connect to the yus daemon. This is a problem because on my gentoo server I already have a YUS database for oddb.org. And as Yasuhiro pointed out: "yus database and its relation objects's owner must be yus user. (not only database)".

Using psql -U postgres and emit \l to list all databases on fastpower I find the following ones containing yus in their name

 bbmb_yus           | postgres | UTF8     | C         | C     | 
 sandoz_yus         | postgres | UTF8     | C         | C     | 
 virbac_yus         | postgres | UTF8     | C         | C     | 
 yus                | postgres | UTF8     | C         | C     | 

Why didn't Yasu use a name like davaz_yus for the database? I will try to create a /var/www/davaz.com/etc/yus.yml.
The page begins to show. See

On oddb-ci2 we used /usr/lib64/apache2/modules/mod_ruby.so which comes from /usr/local/src/mod_ruby/mod_ruby.so. Getting mod_ruby.so from fastpower. Now I get an "Internal Server Error" when looking at (steinwies|davaz).ngiger.ch. But I had copied the file from thinpower, not fastpower. After copying it from fastpower(size 494703), apache2 does not start and emits the error

 * apache2 has detected an error in your setup:
apache2: Syntax error on line 155 of /etc/apache2/httpd.conf: Syntax error on line 4 of /etc/apache2/modules.d/21_mod_ruby.conf: Cannot load /usr/lib64/apache2/modules/mod_ruby.so into server: libruby.so.1.8: cannot open shared object file: No such file or directory
 * ERROR: apache2 failed to stop

even when the file /usr/lib64/apache2/modules/mod_ruby.so exists.

Ran ./gen_mod_ruby_193p547 in /usr/local/src to compile mod_ruby using Ruby 1.9.3.

Had to kill -9 all apache process, remove /var/run/apache2.pid and restart apache. Now the both pages display fine again.

On fastpower we use mod_ruby compiled against Ruby 1.8.6 as seen be lines like RubyAddPath /usr/local/bin/ruby186/lib/ruby in /etc/apache2/modules.d/21_mod_ruby.conf

Why do the image not display correctly? The link points to http://davaz.ngiger.ch/en/personal/life/null. Why?

In the error_log I find

After copying 150MB from /var/www/new.davaz.com/doc/resources/uploads/ on fastpower to oddb-ci2, all images and movies displayed correctly.

I propose to switch mod_ruby on fastpower from running under Ruby 1.8.6 to Ruby 1.9.3 and to adapt the /etc/apache2/modules.d/21_mod_ruby.conf as soon as bbmb and vetoquinol run under Ruby 1.9.

The script gen_mod_ruby_193 calls "make install", which copies files like ruby-run.rb to the sub-directory src/mod_ruby/lib/apache of the installation path defined by the --prefix argument passed to configure.rb. The default is /usr/. E.g

Calling sudo rm -rf /usr/local/lib64/ruby/1.9.1/apache/. After an apache restart, steinwies.ngiger.ch still works.

Looking for erb-run.rb I found a duplicate in /usr/lib64/ruby/1.9.1/apache/erb-run.rb.

Calling sudo rm -rf /usr/lib64/ruby/1.9.1/apache/. After an apache restart, steinwies.ngiger.ch still works.

Calling sudo rm -rf /usr/local/lib64/ruby/1.8/apache. After an apache restart, steinwies.ngiger.ch still works.

Calling sudo rm -rf /usr/local/bin/ruby186/lib/ruby/1.8/apache. After an apache restart, steinwies.ngiger.ch does not work anymore. In the log/error_log I find (eval):127: (eval):127: uninitialized constant Apache::RubyRun (NameError)

But this can be explained, as I found a lines like RubyAddPath /usr/local/bin/ruby186/lib/ in /etc/apache2/modules.d/21_mod_ruby.conf. Removing these lines.

After calling sudo ./gen_mod_ruby_193p547 Apache2 does not start, as says:

  apache2: Syntax error on line 155 of /etc/apache2/httpd.conf: Syntax error on line 4 of /etc/apache2/modules.d/21_mod_ruby.conf:   Cannot load /usr/lib64/apache2/modules/mod_ruby.so into server: /usr/lib64/apache2/modules/mod_ruby.so: undefined symbol: rb_exc_new2

This is bizarr, as I found in https://docs.ruby-lang.org/en/2.1.0/ChangeLog.html that in error.c (rb_exc_new_cstr) as renamed from rb_exc_new2.

Recompiling 1.9.3 from source using gen_ruby_193-p547. And installing mod_ruby again. After restarting apache2 I can access , but not .

In the /var/www/davaz.com/log/error_log I find

Here the paths are messed up. Accessing davaz.ngiger.ch should use the gems from /var/www/davaz.com and not from /var/www/steinwies.ch.

But the SecurityError can probably be circumvented. Trying the solution from https://github.com/rubygems/rubygems/issues/1265.

Adding .untaint to the request_path in /usr/local/lib/ruby/gems/1.9.1/gems/sbsm-1.3.0/lib/sbsm/trans_handler.rb did not help.

After adding a RubyAddPath for each lib directory under /var/www/davaz.com/vendor/ruby/2.3.0/ to the /etc/apache2/vhosts.d/davaz.com.conf I got another error

Copyied the davaz.com.conf to ~/davaz.com.conf.all_vendor (for later inspection if needed).

Changed davaz.com.conf to contain only the following RubyAddPath

RubyAddPath /usr/local/lib/ruby/gems/1.9.1/gems/sbsm-1.3.0/lib
RubyAddPath /usr/local/lib/ruby/gems/1.9.1/gems/rclconf-1.0.0/lib
RubyAddPath /var/www/davaz.com/src

After restarting apache and davaz I get the following error

Changing DRb.start_service('druby://localhost:0') to ::DRb.start_service('druby://localhost:0') did not help neither.

Decided to invest a couple of hours of my spare time to see whether I can switch to another Ruby web framework. These steps were done:

  • sudo emerge nginx
  • created /etc/nginx/sites-enabled/rack_test with the following content
server { 
        listen 8752;
        location / {
          proxy_pass http://localhost:9292;
  }
}
  • sudo /etc/init.d/nginx restart
  • cd /var/www && sudo -u apache git clone https://github.com/rack/rack
  • cd /var/www/rack && sudo -u apache /usr/local/bin/ruby231 -Ilib lib/rack/lobster.rb

And now http://localhost:8752/ displays:

Now my next task is to get the functionality of davaz.com/doc/index.rbx into a copy of the lobster.rb which I put into davaz.com/doc/index_rack.rb.

Now adding /etc/nginx/sites-enabled/davaz_rack with

server { 
        listen 8751;
        location / {
          proxy_pass http://localhost:9191;
  }
}

And starting the doc/index_rack.rb via sudo -u apache /usr/local/bin/bundle exec doc/index_rack.rb

When calling http://localhost:8751/ and passing the request directly as SBSM::Request.new(DaVaz.config.server_uri).process to sbsm 1.3.0 I get a ruby error NameError at /uninitialized constant Apache with a nice callback. Also adding a binding.pry works find.

I will fix this error tomorrow and I think it should be quite easy to adapt it for the use with rack. The index_rack.rb can be found as Attach:index_rack.rb.txt
