NAME

Clustericious::Command::apache - Clustericious command to stat Apache

VERSION

version 1.29

DESCRIPTION

Start an Apache web server. The Apache start and stop commands recognize these options in their configuration section:

pid_file

The location to the pid file. This should usually be the same as the PidFile directive in your Apache configuration.

EXAMPLES

These examples are for Apache 2.4. Getting them to work on Apache 2.2 will require some tweaking.

mod_proxy with hypnotoad

Create a apache24-proxy.conf:

            

              
              
---
% my $root = dir "@{[ home ]}/var/run";
% $root->mkpath(0,0700);
url: http://<%= $host %>:<%= $port %>
start_mode:
  - hypnotoad
  - apache
apache:
  args: -f <%= $root %>/apache.<%= $port %>.conf -E <%= $root %>/apache.<%= $port %>.startup.log
  pid_file: <%= $root %>/apache.<%= $port %>.pid
  autogen:
    filename: <%= $root %>/apache.<%= $port %>.conf
    content: |

      Listen <%= $host %>:<%= $port %>
      ServerName <%= $host %>
      PidFile <%= $root %>/apache.<%= $port %>.pid
       
      ErrorLog   <%= $root %>/apache.<%= $port %>.error.log
      LogFormat "%h %l %u %t \"%r\" %>s %b" common

      <Location />
        ProxyPreserveHost On
        ProxyPass         http://localhost:<%= $port %>/
        ProxyPassReverse  http://localhost:<%= $port %>/
        RequestHeader append set X-Forward-Proto

hypnotoad:
  listen:

  pid_file: <%= $root %>/hypnotoad.<%= $port %>.pid
            
          

Note that this configuration binds hypnotoad to localhost and Apache to the IP that you pass in. Then call from your application's config file:

            

              
              
---
# If hostname() (should be the same as what the command hostname
# prints) is not a valid address that you can bind to, or if 
# your hostname is the IP as localhost, then change the host to
# a literal IP address
% extend_config 'apache24-proxy', host => hostname(), port => 3001;
            
          

CGI

CGI is not recommends, for reasons that are hopefully obvious. It does allow you to run Clustericious from
