Re^4: Apache Server restart fails

[rianne_k]

Thanks for the suggestions. I created the symlink with a2enmod perl. When I to restart the server now, I get a slightly different error message :

rianne@rianne-OXYL015:~$ sudo a2enmod perl
Enabling module perl.
To activate the new configuration, you need to run:
  service apache2 restart
rianne@rianne-OXYL015:~$ service apache2 restart
ulimit: 88: error setting limit (Operation not permitted)

I do have the libapache2-mod-perl2 installed:

 dpkg -l|fgrep apache

Do you see anything missing in there ? Cheers, Rianne

To find what is missing run ldd /usr/lib/apache2/modules/mod_perl.so

[rianne_k]

that is missing indeed:

rianne@rianne-OXYL015:/usr/lib/apache2/modules$ ldd /usr/lib/apache2/m
+odules/mod_perl.so
ldd: /usr/lib/apache2/modules/mod_perl.so: No such file or directory

How do I get it back there?

[rianne_k]

I manually copied mod_perl.so into the right directory (probably not the best approach). Now the server is up and running again, but I still get the error:

I can run run ldd /usr/lib/apache2/modules/mod_perl.so now, this is the outcome:

ldd /usr/lib/apache2/modules/mod_perl.so
    linux-vdso.so.1 =>  (0x00007fffeb376000)

mod_perl.so doesn't make ModPerl::Registry magically installed :)

Doing this manually is hard

[rianne_k]

I reinstalled libapache2-mod-perl2, and for now it seems to be working. Thanks for the help!

Aha, good to know, nevermind Re^7: Apache Server restart fails then :)
