There are two ways you might bump into problems with network connectivity: The iptables firewall, and SELinux. These security mechanisms might prevent your various nodes—management, data, and API—from communicating with each other in various ways and with various symptoms.

Let's have a look at what you're likely to see. 

Data nodes stuck at "starting"

The first thing you might notice is that your data nodes get stuck in the "starting" state. Running show in the management client gives something like this:

    Employee +0 Vote Up -0Vote Down

    Here are the instructions for building mod_jk.

    1. Download the source and untar it.

    2. Ensure you have Sun Studio compiler in your PATH followed by /usr/ccs/bin. Save the following in 'make_solaris.sh' in the 'native' directory :

    #!/bin/sh
    INSTALLDIR=/opt/coolstack
    APACHEDIR=$INSTALLDIR/apache2
    make distclean
    PATH=$INSTALLDIR/bin:$PATH
    export PATH
    ./configure --with-apxs=/opt/coolstack/apache2/bin/apxs --with-java-home=/usr/java --with-prefix=$INSTALLDIR
    make
    make install

    3. Go to the 'native' directory and run ./make_solaris.sh

    4. Edit your httpd.conf file to include :

      LoadModule jk_module        modules/mod_jk.so

    5. Restart the apache httpd server.

    Let me know if this doesn't work for you.
