CentOS/linux rt4 and httpd help!!

y_mullah · 09-14-2012, 09:49 AM

I recently installed rt-4.0.6 on my CentOS 5 distribution. I created /etc/httpd/conf.d/rt4.conf but when I restart my webserver (apache) I get the following error:

[root@localhost conf.d]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: Syntax error on line 11 of /etc/httpd/conf.d/rt4.conf:

this is what the rt4.conf file looks like:

Hi,

Most likely you miss the perl-Log-Dispatch package

Cheers

I installed log-dispatch and when i restarted the server i get this error:

[root@localhost ~]# service httpd restart

and this is what the rt4.conf file looks like:

This is self explanatory: you miss the closing "</Virtualhost>" tag.

BTW using <VirtualHost www.axxentis.com> is not the correct way to define a vhost.
You have to check the "NameVirtualHost ..." option and use the same argument for <VirtualHost ...>. Ie. if you have "NameVirtualHost *:80", you need to use <VirtualHost *:80>. And you need to add inside the vhost stanza:

Code:

ServerName www.axxentis.com

I followed your advice and this is what I get when I restart the server:

You didn't say how you've installed the File::Temp module, but I guess from the INST_FILE, that you didn't use your distro's package manager (yum). That's why you get the same error.
So better run (as root):

Code:

yum update perl-File-Temp

to update the module.

y_mullah · 09-19-2012, 08:15 AM

I've done that and this is what I get when I restart the server:

Syntax error on line 15 of /etc/httpd/conf.d/rt4.conf:
Invalid command 'PerlResponseHandler', perhaps misspelled or defined by a module not included in the server configuration

That means that the perl module is not loaded.
Did you install mod_perl and how? If you used yum, then there should be no such problem.
If you did it from sources, then you need to add in httpd.conf:

Code:

LoadModule perl_module modules/mod_perl.so

Check the actual path to mod_perl.so and if it's not the default /etc/httpd/modules, use the absolute path to it.

y_mullah · 09-20-2012, 02:52 AM

I have added LoadModule perl_module modules/mod_perl.so in my httpd.conf file and this is what I get now:

Syntax error on line 200 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_perl.so into server: libperl.so: cannot open shared object file: No such file or directory

If the module doesn't exist, you need to install it:

Code:

yum install mod_perl

y_mullah · 09-20-2012, 04:16 AM

This is what I get when I do yum install mod_perl

[root@localhost CORE]# yum install mod_perl
Loaded plugins: fastestmirror

bathory · 09-20-2012, 07:50 AM

Does the module actually exist? Run

Code:

ls -l /etc/httpd/modules/mod_perl.so

You may uninstall and reinstall the mod_perl package and see if it works

y_mullah · 09-24-2012, 02:59 AM

This is what I get when I do as you say:

[root@localhost ~]# ls -l /etc/httpd/modules/mod_perl.so
-rwxr-xr-x 1 root root 217160 Jan 21 2009 /etc/httpd/modules/mod_perl.so

I uninstalled and reinstalled mod_perl but then still got the same error when I try to restart the server.

Maybe you hit this bug and you need to upgrade to mod_perl-2.0.4-7.
