USCD1 Plugin
On the previous page I have shown how easy it is to modify Uniform Server 3.5-Apollo and have it running from a CD. You currently have a collection of old and new files neatly saved in folder uscd, we now put these to good use by creating a test plugin for UniServer.
Plugin
This plugin is not overly complex it allows you to switch Uniform Server to CD mode where you can burn your design and then switch back to standard mode. To achieve switching two batches files are required one for each mode. Our design needs a reference point allowing relative paths to be used. Uniform Server already provides a plugins folder which meets our requirements.
Files and location
Currently we have a collection of files in folder uscd these I have listed below. During switching these files are copied to the location shown. While copying each file its name is changed back to the original. To perform this copying we use two batch files cd_mode_switch.bat copies only the new files and us_mode_switch.bat copies original (old) files, thus switching between CD and normal Uniform Server mode respectively.
| File | Location | |
|---|---|---|
| new_httpd.conf old_httpd.conf |
*\Uniform Server\udrive\usr\local\apache2\conf | Apache |
| new_my-small.cnf old_my-small.cnf |
*\Uniform Server\udrive\usr\local\mysql\bin | MySQL |
| new_php.ini old_php.ini |
*\Uniform Serve\udrive\usr\local\php | PHP |
| new_config.inc.php old_config.inc.php |
*\Uniform Serve\udrive\home\admin\www\phpMyAdmin | phpMyAdmin |
| new_Server_Start.bat old_Server_Start.bat |
*\Uniform Server | UniServer Control |
| new_Stop.bat old_Stop.bat |
*\Uniform Server | UniServer Cont |
Preperation
Create a new folder uscd1 in folder *\Uniform Server\udrive\plugins now copy the folder uscd to uscd1.
- Folder uscd1: Will contain two new batch files cd_mode.bat and us_mode.bat these call batch files us_mode_switch.bat and cd_mode_switch.bat respectively. They can be moved to the top level folder (Uniform Server) each file contains a single line of code hence are easily modified to run the main switching batch files.
- Folder uscd: Will contain two new batch files cd_mode_switch.bat and us_mode_switch.bat these perform file copying and renaming. Strictly speaking these are the only two files required for switching.
Note: Using four files provides a flexible architecture I prefer to have all my control files located in the top level folder you can choose whatever suits your need better.
Batch file commands
Before looking at the batch files an understanding of the commands used will make the whole process easier to understand.
| Batch Command | Explanation |
|---|---|
pushd %~dp0 .... batch file code .... popd |
|
COPY switches source destination |
COPY switches source destination Copies one or more files to another location. Source: Complete path and name of the file to copy. Destination: Complete path and file name to where we wish to copy the above file. The file name can be different to that of the source file. (We use this to change names back to their originals) Switches: /Y Suppresses prompting to confirm you want to overwrite an existing destination file. |
..\folder\file_name ..\..\folder\file_name |
..\ not a DOS command Its a relative path name ..\ means move up one folder level ..\..\ move up two folder levels. ..\folder_name\folder_name\file_name Move up one folder level and then start moving down following the folder names to the file name. Note: Relative to the current working directory (folder) as established above using pushd. |
us_mode_switch.bat
Double click on this file and you are back to a default installation of Uniform Server (Well the files we have been using). The above comments also apply to this file.

How to use the plugin
Before running the servers it is good practice to run either us_mode.bat or cd_mode.bat.
- us_mode.bat If you are developing a web site this selects the normal Uniform Server mode.
- cd_mode.bat When you are ready to transfer the servers and site/s to a CD run this batch file to setup CD mode. There is no need to start the servers just copy folder Uniform Server and all its content to a CD.
Download
Download this overlay (plugin USCD1) file CD Part 2 copy the file to folder Uniform Server double click to extract the files. See above file overview for details of file locations.
What's next
The above is a solid foundation for producing a plugin, it can be used as is but lacks features that a real plugin should have. Part 3 revisits what we currently have and resolves these shortcomings.
