Installing ColdFusion 7.0.2 with Apache 2.2 using CentOS 5

Tuesday April 25, 2017 9:46:05

This page is to help those who have laboured hard trying to get Coldfusion running under Linux and more recently with the new version of Apache 2.2.

CentOS 5 is a open source version of Redhat 5 enterprise which is relatively easy to get working and interacts fairly easily with Coldfusion although as you will read in what follows a few tweaks are necessary. Adobe claim that Redhat is officially supported but this might lead one to suspect that things will flow smoothly. They do not! I also found some of the support pages on Adobe to be difficult to deal with and some typographical errors seemed to make all the difference.

I have developed these notes from excellent help already available on the Internet which I will reference throughout and several installations later. Depending on the machine and the weather (it seems!) no installation is the same. While the material available on the Internet helped tremendously I found that in some cases it was (not to be unkind) not the most productive way to go and assumed away certain problems that have taken me some time to solve. So the sequence of events I outline here represents what I now think is the best way to go and which will work on (almost) any machine. It is more laborious but will get the job done.

Preparation:

Step 1: - Turn off SELinux

I consider it to give problems although if you read Steve Erat's excellent guide to installing Coldfusion on Fedora 6 (essentially CentOS 5) you will find he has some tweaks to overcome the problems. I prefer to deal with security at the firewall.

Step 2: - Check your version of Apache to make sure you have the issue

[root@machine]# httpd -v
Server version: Apache/2.2.3
Server built: Mar 21 2007 19:10:36

So we know that a hotfix is currently available from Adobe to deal with the Apache 2.2. problem. The wsconfig.zip file provided should be downloaded.

After some experimentation I decided the best way was to make a directory for it on the Desktop which I called holder, unzip it and manually copy the JRun Apache 2.2 module mod_jrun22 to its final destination (more about which later). This was after I tried the instructions which accompanied the hotfix. On one machine they work while on another they do not. So

[root@machine holder]# unzip wsconfig.zip

To check the version of Linux to make sure any problems you encounter which my plan are not related to the distribution. Note I updated the Final release for some security fixes before I started - yum update.

[root@machine]#cat /etc/redhat-release
CentOS release 5 (Final)

Step 3: - Get the libXp runtime library

You will find that you need the X.Org X11 libXp runtime library which you can get from CentOS mirrors. Look for libXp-1.0.0-9.i386.rpm. Install it ahead of the Coldfusion installation to save yourself the problem that I describe below.

Step 3: - Pre-install the legacy C libraries

Make sure you install the Legacy C library when you setup linux. You should also check the presence of the shared libraries - libc.so.6. The installation requires them but the Coldfusion installation script seems to think it is missing.

[root@machine]# rpm -q --whatprovides libc.so.6
glibc-2.5-12
[root@machine]# rpm -q glibc
glibc-2.5-12

This establishes that I have the shared libaries installed. You will get an error during the Coldfusion installation anyway. I got the following solution from Steve Erat. I found this part of his resource very helpful and was very grateful.

Step 4: - add a runtime Coldfusion user

Tip: Make sure you have a run-time user installed on your system. For example, cfm. It should not be root.

Starting the Coldfusion installation:

Step 1:

This is the output from the installer after I launch the installation script as below. Also while Adobe says you can use the ./coldfusion-702-linux.bin -i gui switch it doesn't work on this distribution of Linux although I have used it on CentOS 4 Final.

[root@machine]# ./coldfusion-702-linux.bin

/tmp/install.dir.3348/Linux/resource/jre/bin/java: error while loading shared libraries: libpthread.so.0: 
cannot open shared object file: No such file or directory

What is the solution to this?

Well until Adobe update their scripts the solution requires some editing of the installation scripts. Steve Erat documents this well and the steps require you to: (a) back up your coldfusion binary; (b) edit the installation script to weed out the offending lines. Note that he has compiled the shared wisdom from several sources including Dave Shuck. So the steps are:

1. Rename binary

[root@machine]# cp coldfusion-702-linux.bin coldfusion-702-linux.bin.backup

2. Use the following string replace command on the binary to comment out the line that is causing the problem

[root@machine]# cat coldfusion-702-linux.bin.backup | sed "s/export LD_ASSUME/#xport LD_ASSUME/" > coldfusion-702-linux.bin

3. Make the modified binary executable

[root@machine]# chmod 755 coldfusion-702-linux.bin

Step 2: - rerun the installation script

Now you have a choice. Once the installation script is running you will be asked whether to install with a WWW server (such as Apache) or finish the installation in Coldfusion's standalone server mode and then connect to Apache later. I guess it is here that I depart from Steve Erat and others who advocate installing the built-in webserver initially. I have done it both ways and I think additional problems (albeit trivial) emerge if you start with the built-in approach and then connect later. I think it is better to anticipate the now known problems and manually make the connection between Coldfusion and Apache so that it works from scratch.

Anyway, run the script and follow the screens making the relevant choices. The following output would have been generated if you installed the in-built server.

[root@machine]# ./coldfusion-702-linux.bin

[HERE YOU MAKE YOUR SELECTIONS AND READ A LONG LICENCE AND THEN YOU GET]

....

You have successfully completed the first step in installing Macromedia 
ColdFusion MX 7.

To continue with your installation, go to /opt/coldfusionmx7/bin and type 
"./coldfusion start" to start your server.

Once the server is started log in to the Configuration Wizard at 
http://[machinename]:8500/CFIDE/administrator/index.cfm

PRESS  TO EXIT THE INSTALLER:

Step 3: - Start the Coldfusion service

Now, if you had have installed the built-in server you would do the following:

1. Go to /opt/coldfusionmx7/bin and start the server

[root@machine bin]# ./coldfusion start

Starting ColdFusion MX 7...
The ColdFusion MX 7 server is starting up and will be available shortly.
======================================================================
ColdFusion MX 7 has been started.
ColdFusion MX 7 will write logs to /opt/coldfusionmx7/logs/cfserver.log
======================================================================

You can also start and stop the service using the Linux command service coldfusionmx7 start (stop). Now you are ready to login to the Coldfusion Administrator and finish the installation.

Step 4: - Graphing Service Not Available problem

Go to http://127.0.0.1:8500/CFIDE/administrator/index.cfm if you installed the built-in server and you will get an error if you didn't take the earlier tip to install the libXp runtime libary. You can go to the cfserver.log to find out that it is related to the Graphing Service. Here is the output to the log file.

05/22 21:33:25 Error [main] - Unable to initialize Graphing service: java.lang.UnsatisfiedLinkError: 
/opt/coldfusionmx7/runtime/jre/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such 
file or directory

So if you prepared well you will not have this problem - that is you will have already installed this runtime library. If you haven't go back to the preparation section and find the libXp rpm and install it with yum.

Step 5: - Restart the Coldfusion service

Restarting the service allows you to login to the Administrator and the first-time setup script executes. Your problems are however just beginning if you have Apache 2.2 running.

Connecting Coldfusion to the Apache WWW server

There are three clear options here. I will outline my preferred route as Option 3 and I recognise that approach is not part of the consensus out there in Coldfusion land that says that make the connection after you have Coldfusion up and running with its built-in server as described above. I have done it all three ways and conclude that Options 1 and 2 work sometimes but not always whereas Option 3 is failsafe.

Option 1

Follow the built-in method above and then try to make the connection to Apache later. This will involve the following steps:

1. Download the wsconfig hotfix from Adobe

2. Configure the connector script. The following settings should be used in the apache_connector.sh found at /opt/coldfusionmx7/bin/connectors directory. You can find the relevant parameters as follows:

[root@machine bin]# rpm -q httpd
httpd-2.2.3-6.el5.centos.1

[root@machine bin]# which httpd
/usr/sbin/httpd

[root@machine bin]# httpd -v
Server version: Apache/2.2.3
Server built:   Mar 21 2007 19:10:3

[root@machine bin]# which apachectl
/usr/sbin/apachectl

3. Nano the apache_connector.sh as you will see:

#!/bin/sh

#
# Configure the Apache connector.
# -dir should be the *directory* which contains httpd.conf
# -bin should be the path to the apache *executable*
# -script should be the path to the script which is used to
# start/stop apache
#
../../runtime/bin/wsconfig \
-server coldfusion \
-ws apache \
-dir /etc/httpd/conf \
-bin /usr/sbin/httpd \
-script /usr/sbin/apachectl \
-coldfusion 

exit $#

4. Then run the connector script:

[root@machine connectors]# ./apache_connector.sh 

Could not connect to any JRun/ColdFusion servers on host localhost.
Possible causes:
o Server not running
-Start Macromedia JRun4 or ColdFusion MX server
o Server running
-JNDI listen port in jndi.properties blocked by TCP/IP filtering or firewall
on server
-host restriction in security.properties blocking communication with server

It was here that problems emerged. Steve Erat has some simple checks to follow which include

(a) Checking that the JNDI port was being listened to (2920 as defined in SERVER-INF/jndi.properties)

[root@machine ~]# netstat -antp | grep "cfmx7"
tcp 0 0 :::51011   :::*   LISTEN 3971/cfmx7 
tcp 0 0 :::2920   :::*   LISTEN 3971/cfmx7 
tcp 0 0 :::1099   :::*   LISTEN 3971/cfmx7 
tcp 0 0 :::45742   :::*   LISTEN 3971/cfmx7 
tcp 0 0 :::8500   :::*   LISTEN 3971/cfmx7

(b) Checking /etc/hosts

[root@machine ~]# more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
[machine IP address] [machine_name.domain] [machine_alias]
::1     localhost6.localdomain6 localhost6
127.0.0.1 bilbo localhost

I generally failed to get past this point for reasons that are unknown and not covered by Steve's communication. Typically everything seemed to be okay but the connector wouldn't connect. So we turn to Option 2.

Option 2 - Adobe hotfix method

You can try the Adobe method which is well described here. It didn't work consistently for me however. Although you have to go there to get the new wsconfig.zip which has the updated jar file that you need to make the connection.

Option 3 - Manual installation

This is the preferred option in my view and should be done after you have installed Coldfusion but before you have tried to start it for the first time.

You can find a useful guide from Adobe and some of the steps below follow that guide closely.

Step 1: - Edit the jrun.xml file

Open the /opt/coldfusionmx7/runtime/servers/coldfusion/SERVER-INF/jrun.xml file and

  • Find the entry labeled ProxyService
  • Add <attribute name="deactivated">false</attribute>
  • Save the file

If you had used the built-in option in the initial installation you would have to edit the JRun server entry (just above the Proxy Server xml) as:

  • Find the entry labeled JRunService
  • Change <attribute name="deactivated">true</attribute>>
This turns off access to Port 8500 and will then redirect the requests to Port 80 once you connect to Apache. This is one of the unnecessary things you have to do if you took the built-in option.

So it should look like the following. Also see here which was helpful.

For one virtual server (Apache) only you can turn the multi-host cacheRealPath option to true.

Step 2: - Create a directory for the virtual server

Create the following directory under under wsconfig:

  • /opt/coldfusionmx7/runtime/lib/wsconfig/1

Step 3: - Configuration file creation

(1) Create a file named wsconfig.properties in the /opt/coldfusionmx7/runtime/lib/wsconfig directory. This file has information necessary about the Apache web server configuration.

(2)Nano wsconfig.properties

#JRun Web Server Configuration File
# edited by bill 10.31 Thur May 24
1=Apache,/etc/httpd/conf,"","",""
1 .srv=localhost,"coldfusion"

(3) Save the file.

Step 4: - Configuring Apache

(1) Create a file jrunserver.store in the /opt/coldfusionmx7/runtime/lib/wsconfig/1 directory and edit it with

proxyservers=127.0.0.1:51011 The 51011 is for ColdFusion MX 7:

(2) After you had unzipped the wsconfig.jar from the Adobe hotfix download you can search within the huge number of files contained to find the mod_jrun22.so which is the fix for Apache 2.2 and above. You need to place this in the /opt/coldfusionmx7/runtime/lib/wsconfig/1 directory as well. Just copy it over. See also this which I found helpful.

(3) Nano /etc/httpd/conf/httpd.conf and at the end of the configuration file add the following lines of code. You can cut and paste from here if you like (making sure you keep everything on one line as below:

# JRun Settings
LoadModule jrun_module /opt/coldfusionmx7/runtime/lib/wsconfig/1/mod_jrun22.so
<IfModule mod_jrun22.c>
JRunConfig Verbose false
JRunConfig Apialloc false
JRunConfig Ssl false
JRunConfig Ignoresuffixmap false
JRunConfig Serverstore /opt/coldfusionmx7/runtime/lib/wsconfig/1/jrunserver.store
JRunConfig Bootstrap 127.0.0.1:51011
#JRunConfig Errorurl <optionally redirect to this URL on errors>
AddHandler jrun-handler .cfm .cfml .cfc .jsp .jws .cfr .cfswf
</IfModule>

Note:

  • The Adobe document I referred to above on manual installation reflects its age because it refers to mod_jrun20.so. If you cut and paste from their instructions make sure you edit the mod_jrun20.so to make it mod_jrun22.so, which was the file in the Apache 2.2 hotfix.
  • JRunConfig Bootstrap 127.0.0.1:51011 is for Coldfusion MX7 and points to the server and proxy port of the JRun server.

Step 4: - Running the servers together

Now start Apache and Coldfusion:

[root@machine ~]# service httpd start

[root@machine ~]# service coldfusionmx7 start

Things should now nearly work.

Other Issues

  • If you used the built-in option you will have your CFIDE directory under the /opt/coldfusionmx7/wwwroot directory. You either have to move that over wholesale to the Apache WWW directory (default is /var/www/html) or create a symlink to it from the /var/www/html. Theories abound as to what is best.The problem that you will notice is that the images accompanying the Coldfusion Administrator are broken because it cannot find the images directory under the CFIDE directory. Either solution fixes this and also fixes the problem of finding CF scripts necessary for CFform, among other things.
  • You may find that you will still be accessing an index.cfm file in the /opt/coldfusionmx7/wwwroot even though you clearly deactivated it on Port 8500. I wrestled with this for a while before I worked out that if I deleted the index.cfm and copied it over to the /var/www/html directory Apache did its things beautifully with prior help from the Coldfusion server.
  • If you want index.cfm files served from the Apache WWW root then you need to add the index.cfm option to the Directory config in httpd.conf

That is it for now. Comments appreciated.

Next I will document hooking up MySQL 5 with Coldfusion MX7 which is very easy.
