Chapter 7:  Using Multiple Server Instances

Configuring application isolation in Apache

When you use multiple virtual hosts with multiple server instances under Apache, you edit the 
httpd.conf file manually.

This section assumes that you already created server instances and virtual websites, as described in 

To configure multiple server instances for application isolation when using Apache:

1.

Run the Web Server Configuration Tool once, specifying the location of the Apache httpd.conf 
file and any other required information. Ensure that you select the Configure Web Server for 
ColdFusion MX Applications check box (GUI) or use the 

-coldfusion

 option (command-

line).

2.

The Web Server Configuration Tool creates a sequentially numbered subdirectory under 
jrun_root/lib/wsconfig. You can use the subdirectory created by the Web Server Configuration 
Tool for one of your virtual hosts, but you must create additional subdirectories for all other 
virtual hosts. For example, the first time you run the Web Server Configuration Tool, it creates 
jrun_root/lib/wsconfig/1; if you have two other virtual hosts, you must manually create two 
other directories (jrun_root/lib/wsconfig/mystore and jrun_root/lib/wsconfig/myemp in this 
example). These directories can be empty.

3.

Open the jrun_root/servers/servername/SERVER-INF/jrun.xml file for each of your server 
instances, locate the 

ProxyService

 service, ensure that the 

deactivated

 element is set to false, 

and note the value of the port element; for example:

...
<service class="jrun.servlet.jrpp.JRunProxyService" name="ProxyService">
  <attribute name="activeHandlerThreads">25</attribute>
  <attribute name="backlog">500</attribute>
  <attribute name="deactivated">false</attribute> 
  <attribute name="interface">*</attribute>
  <attribute name="maxHandlerThreads">1000</attribute>
  <attribute name="minHandlerThreads">1</attribute>
  <attribute name="port">51002</attribute> 
...

4.

Restart each of the modified JRun servers.

5.

Open the apache_root/conf/httpd.conf file in a text editor and find the 

VirtualHost

 directives. 

The settings added by the Web Server Configuration Tool are after the last 

</IfModule>

 

directive, as the following example shows:

...
# JRun Settings
LoadModule jrun_module "C:/JRun4/lib/wsconfig/1/mod_jrun20.so"
<IfModule mod_jrun20.c>
    JRunConfig Verbose false
    JRunConfig Apialloc false
    JRunConfig Ssl false
    JRunConfig Ignoresuffixmap false
    JRunConfig Serverstore "C:/JRun4/lib/wsconfig/1/jrunserver.store"
    JRunConfig Bootstrap 127.0.0.1:51000
    #JRunConfig Errorurl <optionally redirect to this URL on errors>
