Apache is not getting started after adding mod_proxy_cluster

i am trying to use my HTTP server as load balancer to my Application-server cluster setup. so, i downloaded mod_proxy_cluster binaries and added below files to {$apache-home}/modules directory.

 mod_proxy.so 
 mod_proxy_ajp.so 
 mod_slotmem.so 
 mod_manager.so 
 mod_proxy_cluster.so 
 mod_advertise.so

and also i added below lines in the httpd.conf file.

 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

and then i tried to restart the Apache server but it is not getting started.. i tried a couple of times.. but no luck... can anybody tell me where i am wrong? thank you, in advance.

It is configurable; set MemManagerFile /your/path/to/httpd/cache/mod_cluster outside VirtualHost scope. Older mod_cluster versions were trying to store shm files in log/ directory by default. The current versions, 1.3.x, use the proper cache/ dir though.

In ubuntu, try to view the apache log file at /var/log/apache2/error.log If there is a line like this :

[Wed Aug 13 17:57:19 2014] [emerg] create_mem_node /etc/apache2/logs/manager.node failed: No such file or directory
Configuration Failed

So, just create a folder named logs in the /etc/apache2, then grant the permission to this folder. No, you can start apache2 by apachectl start, then use netstat -tupln to check whether apache2 was started. (view port 80)
