Ruby doesn't execute and show source

Create the old mod_ruby.so for apache 2.4 using Ubuntu 14.04

Make sure you're using ruby 1.9 - it unlikely will work with newer versions!
Some logging and probably auth informations will not work. This module is considered obsolete and nobody will give you support if something goes wrong.
There is no guarantee this will work for you or the results are as expected.
I would not recommend using it on productive systems. It probably is useless but ....



We need a few build tools and dev packages

Code:

apt-get install cmake libaprutil1-dev libapr1-dev ruby ruby-dev apache2-dev

Prepare folders and build dir.

Code:

mkdir /usr/local/src/mod_ruby_old
cd /usr/local/src/mod_ruby_old
wget https://github.com/shugo/mod_ruby/archive/master.zip
unzip master.zip

Put the attached patch to the current directory /usr/local/src/mod_ruby_old and apply the patch

Code:

cd mod_ruby-master
patch -i ../mod_ruby.txt

Now lets make it

Code:

./configure.rb --with-apxs --with-apr-includes=/usr/include/apr-1.0
make
make install

Create /etc/apache2/mods-available/ruby.load with the following content

Code:

LoadModule ruby_module /usr/lib/apache2/modules/mod_ruby.so

Code:

a2enmod ruby

Now just enable Ruby in your ISPConfig

 

Thanks it compiled and i could install mod_ruby but after apache restart it doesn't open any page and pages just loading and in apache error log i have:

Code:

So i disable mod_ruby and now apache works

 

it could not make and return error:

Hmm I wasn't able to reproduce either the first nor the second issue :/
Did you see any errors while applying the patch file?
My ruby.c looks like
http://s000.tinyupload.com/index.php?file_id=21370299087222088094

I don't think that's a 32/64bit issue

if I have some time later, I'll try on 64 bit

Oh and I didn't need
"RubyConfig GEM_PATH /usr/lib/ruby/gems/2.0.0/gems/"

 

Are u sure your patch file is correct ? it seems on ) is lost:
also i replace my mod_ruby.c file with yours and i get error when run make.
and it's output of patch:

Yes, I did all the steps I posted on fresh source to verify they're working.
The line you're seeing there is just a marker for the patch program.
It belongs to server.c line 70 which indeed has a newline at this point

 

i removed everything and uzip again and now patch with fixed last line and it was output of patch then configure then make and it shows error

What about error for previous mod_ruby ? it's old one the previous complied but apache segment fault for it

 

Again, the patch file is alright, no need to fix anything. Regarding your segmention fault - I've not been able to reproduce this issue - you could try installing -dbg files and debug what's wrong or where it fails.
Have you enabled any 3rd party repositories ? I was using stock debian 8 and ubuntu 14.04 and did not have any issues, well but 32bit

 

But it worked.Thanks

 

I'm going to try it on 64bit anyway It's bothering me it didn't work for you, so I give it one last attempt to compile it on 64bit.
However, keep in mind using CGI is slow and it allows any program beeing executed since it's not limited to #!/usr/bin/ruby ...

 

Thanks a lot i never forget it

You'r right. but its better something work as a ruby feature until there is checkbox that doesn't do anything

 

Indeed, it does behave a bit different. I did some debugging but as said, it's none of my daily business rewriting apache modules
We do have an issue somewhere

However, I was curious and I got a solution ( maybe ) - however, I just played around and I defnitly don't know how it will effect anything but the new mod_ruby does not segfault anymore....

change src/ruby.cpp startup function to the following code

Code:

void startup(const char* script_name)
{
    if (running)
    {
        return;
    }

    int fake_argc = 0;
//    char* fake_args[fake_argc];
//    char** fake_argv = fake_args;
    char **fake_argv;

    ruby_sysinit(&fake_argc, &fake_argv);

    // Initialize Ruby itself
    RUBY_INIT_STACK;
    ruby_init();

    ruby_init_loadpath();
    //Init_prelude();
    //ruby_init_gems();

    // To load prelude.rb
//    static char* args[] = { "ruby", "/dev/null" };
//    ruby_process_options(2,args);

    // Load Ruby encodings, otherwise we'll get all kinds of "Unitialized
    // constanct Encoding::UTF-7", etc. everywhere.
//    rb_enc_find_index("encdb");

//    VALUE gem;
//    gem = rb_define_module("Gem");
//    rb_const_set(gem, rb_intern("Enable"), Qtrue);
//    rb_require("rubygems");




    ruby_script((char*)script_name);

    running = true;


}

This is for the new mod_ruby, not the old one.
The old mod_ruby does compile well! ( but segfaults aswell on 64bit ) but there's no issue like you described.

 

Thanks it worked now.
i put mod-ruby.deb package for everyone needs to install it on ubuntu 64bit
so just enable it and change template
