I am doing clustering in Tomcat 7 with Apache server. It is working fine too. However I have the following issues:

1) I am trying to monitor the mod_jk status page; but it is giving 404 error.

2) in Log following error is shown -

[Tue Dec 17 13:16:51.019 2013] [2236:140599476504544] [error] init_jk::mod_jk.c (3348): Initializing shm:/etc/httpd/logs/mod_jk.shm.2236 errno=13. Load balancing workers will not function properly.

Here is worker.properties file

worker.list=tomcatnode1,tomcatnode2,loadbalancer,statusmanager

worker.tomcatnode1.port=8009
worker.tomcatnode1.host=localhost
worker.tomcatnode1.type=ajp13
worker.tomcatnode1.lbfactor=100

worker.tomcatnode2.port=8010
worker.tomcatnode2.host=localhost
worker.tomcatnode2.type=ajp13
worker.tomcatnode2.lbfactor=100


#Load Balance Configuration
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=tomcatnode1, tomcatnode2
worker.loadbalancer.sticky_session=1

#worker.list=jkstatus
worker.statusmanager.type=status

Here is mod_jk.conf file

LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel info
JkShmFile logs/mod_jk.shm
JkMount /IntellixWebApi/* loadbalancer
#JkMount /jkmanager/* jkstatus
#JkMount /jkmanager jkstatus

<Location /status/>
    JkMount statusmanager
    Order deny,allow
#   Deny from all
    Allow from 127.0.0.1
</Location>

If I am accessing IntellixWebApi; it is accessable. but When I am using /status; it is not working.

Please suggest.

Thanks

After lots of googling; I am able to get the jk_manager status screen. Firstly I have disable the SELINUX and then after restarting the system; I set the following JkMount

JkMount /* loadbalancer
JkMount /IntellixWebApi/* loadbalancer
JkMount /jkmanager/* jkstatus

<Location /status/>
    JkMount statusmanager
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
</Location>

This worked for me.

Thanks
