getting [emerg] create_mem_node /etc/httpd/logs/manager.node failed: Permission denied Configuration Failed when starting apache on rhel 6 after mod_cluster is added

[claudianus]

Hello all -

I am getting the following error when I try to start apache on rhel 6.

[emerg] create_mem_node /etc/httpd/logs/manager.node failed: Permission denied

Configuration Failed

Note that apache was working fine before I uploaded mod_cluster modules and configured it. I also had mod_jk configured and working with apache before this, which I disabled.

I am trying to run apache with mod_cluster 1.2.0.Final on rhel 6 x64.

I am also starting apache as root (starting it as a regular user causes permission denied error).

Finally, note that I tried to run it both with SELinux enabled and disabled and the outcome seems to be the same.

My mod_cluster conf looks like below

LoadModule slotmem_module modules/mod_slotmem.so

LoadModule manager_module modules/mod_manager.so

LoadModule proxy_cluster_module modules/mod_proxy_cluster.so

LoadModule advertise_module modules/mod_advertise.so

#Listen 192.168.10.91:8008

<VirtualHost 192.168.10.91:8008>

    <Directory />

        Order deny,allow

        Deny from all

    Allow from 127.0.0.1

    Allow from 192.168.10.

    </Directory>

    <Location /mod_cluster-manager>

        SetHandler mod_cluster-manager

        Order deny,allow

    Deny from all

    Allow from 127.0.0.1

        Allow from 192.168.10.

    </Location>

          ManagerBalancerName mycluster

      KeepAliveTimeout 60

      MaxKeepAliveRequests 0

          ServerAdvertise On

      EnableMCPMReceive

</VirtualHost>

I commented out the Listen directive because I put it in the main http.conf file (having it in this file does not change the outcome) and the above mod_cluster.conf file is located under my /etc/http/conf.d/ folder.

I also saw that there is a bug related to this error but under Windows OS.

What am I missing?

Thanks

I solved the issue.

It was SELinux after all.

I ran "sealert -a /var/log/audit/audit.log | less" and saw that SELinux was denying httd write permissions to the /etc/httpd/logs/manager.node.nodes.lock file. So I temporaryly enabled it by running the following two lines

"grep httpd /var/log/audit/audit.log | audit2allow -M mypol"

"semodule -i mypol.pp"

I then went and removed the locks

"rm -f /etc/httpd/logs/manager.node.nodes.lock"

"rm -f /var/lock/subsys/httpd"

and then resstarted httpd ("service httpd start")

That did the trick. I still see some errors in the log but at least for now httpd is running and I can see the mod_cluster-manager page.

Your fixed did not work out for me, this def worked:

Using mod_cluster and SELinux.
