Configuring TileCache on Windows and Linux

Question

I want to do tile caching for MapServer map files by using TileCache application. For this I have installed Python 2.7 and TileCache 2.11 and applied the following sequence of steps:

1. Extracted TileCache-2.11 tar file to my apache web directory into a folder tilecache Changed Disk Cache location in tilecache.cfg to my local folder
2. Replaced name, srs, url with my map file in place of basic layer
3. tested in browser using the url http://localhost:8088/tilecache/tilecache.cgi?LAYERS=APdem&&SERVICE=WMS&FORMAT=image/png&VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-180,-90,0,90

But i'm getting tilecache.cfg python code in the browser as:

 from TileCache import Service, cgiHandler, cfgfiles
if __name__ == '__main__':
 svc = Service.load("tilecache.cfg")
 cgiHandler(svc)

Is there any step missed in my process or what went wrong? In Linux the apache httpd.conf file is as follows

 ServerRoot "/etc/httpd"
Listen 80
Include conf.modules.d/*.conf

ServerAdmin root@localhost

the tilecache.cfg file is as follows

[cache]
type=Disk
base=/var/www/tilecache
[basic]
type=WMS
url=http://labs.metacarta.com/wms/vmap0
extension=png
[apdem]
type=WMS
url=https://test.com/mapserver/cgi-bin/mapserv?map=RMapFiles/apdem.map
extension=png
srs=EPSG:4326
layers=apdem

I have changed working directory in apache from html to cgi-bin the following error is appearing I extracted the tilecache code into cgi-bin and now the error was rectified with new error asAn error occurred:

File contains no section headers.

• Satya Chandra: I'm facing same issue in Linux also. I followed steps from tilecache.org/docs/README.html
• Fran Raga: That file is there, tilecache.cfg?You may need something like this, svc = Service.load("C:\\TileCache\\tilecache.cfg") but with your path
• Satya Chandra: Even if i gives the relative path to tilecache.cfg , it displaying the error with the path.
• Satya Chandra: #!/usr/bin/env python from TileCache import Service, cgiHandler, cfgfiles If I gives the cfg file path the error as follows if name == 'main': svc = Service.load('/var/www/html/tilecache-2.11/tilecache.cfg') cgiHandler(svc)

Answer 1

After struggling one week I'm able to configure tilecache in Linux o.s. I also tested alongwith OL3 and working fine. The main problem is that the it is not reading tilecache.cfg files from correct path. So you have to give your absolute path for cfg files wherever required like in tilecache.cgi and services.py files. For mapserver service the mapscript module should be installed.

Answer 2

The TileCache installation instructions have one more step:

Permit CGI execution in the TileCache directory. For example, if TileCache is to be run with Apache, the following must be added in your Apache configuration, where /var/www/tilecache is the directory resulting from the code extraction. On Debian, this is typically /usr/lib/cgi-bin.

<Directory /var/www/tilecache>
 AddHandler cgi-script .cgi
 Options +ExecCGI
</Directory>

• Satya Chandra: This is already included.
• CL.: It is included in the Apache configuration that listens on port 80. The server that listens on port 8088 apparently has no such configuration. What is running on 8088? Another Apache? What happens if you change the port to 80 in the URL?
• Satya Chandra: I have tested changed port also but same problem
• Satya Chandra: Now it is giving error as, An error occurred: The requested layer () does not exist. Available layers are1: * apdem
• CL.: The line d# Configuration for MC TileCache does not occur in the file shown in the question.
