ms4w+tilecache+openlayers配置xuhy总结

 

参考http://opengeo.cn/bbs/simple/index.php?t64.html

1.      安装ms4w，保证apache正常运行

2.      安装python2.5 我的也是arcgis自带了的，严重怀疑我自己下的python2.5安装程序有问题，今天在办公室整了一天都没有头绪，当然办公室是win7

3.      安装mod_python-3.3.1.win32-py2.5-Apache2.2.exe

4.      解压tilecache-2.11.zip到C:\ms4w\apps，这个目录中最好不要有program files这样的中间有空格的目录

5.      打开Apache的conf\ httpd.conf文件，在#LoadModule后添加

LoadModule python_module modules/mod_python.so

还是在conf\ httpd.conf文件中，在


    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all


下添加
Alias /tilecache/ "C:/ms4w/apps/tilecache-2.11/"

AddHandlerpython-program .py

PythonHandlerTileCache.Service

PythonOptionTileCacheConfig C:/ms4w/apps/tilecache-2.11/tilecache.cfg

PythonDebug On

Allow from all

 

AddHandlercgi-script .cgi .pl

AddHandlermod_python .py

 

6.       C:/tilecache-2.10/目录下的tilecache.cgi文件，将第一行改成#!C:\Python25\python.exe –u

本来是（这个在openlayers的ProxyHost中也有用，并且必须将文件另存为unicode-ascii编码格式，害得大爷我研究了一个晚上）

改成如下

之后将tilecache.cgi文件的后缀改为.py，也就是使其转变成tilecache.py文件

 

7.       修改C:/tilecache-2.10/目录下的tilecache.cfg文件，修改位置为

[cache]
type=Disk
base=C:/tilecache-2.10/tmp/tilecache

其中的base指存储地图瓦片的目录

修改后内容为：

# Configurationfor MC TileCache

 

# TileCache canload Layers or Caches from anywhere in sys.path. If you

# prefer to loadfrom somewhere which is *not* on sys.path, you can use

# the pathconfiguration paramter to set a comma-seperated list of

# filesystempaths which you want prepended to sys.path.

#[tilecache_options]

#path=/home/you

 

# Some TileCacheoptions are controlled by metadata. One example is the

#crossdomain_sites option, which allows you to add sites which are then

# included in acrossdomain.xml file served from the root of the TileCache

#[metadata]

#crossdomain_sites=openstreetmap.org,openaerialmap.org

 

# [cache]section examples: (mandatory!)

#

# Disk:

# [cache]

# type=Disk   (works out of the box)

# base=

#

# Memcached:

# [cache]

#type=Memcached  (you'll need memcache.pyand memcached running!)

#servers=192.168.1.1:11211

#

# Amazon S3:

# [cache]

# type=AWSS3

#access_key=your_access_key

#secret_access_key=your_secret_access_key

 

[cache]

type=Disk

base=C:/ms4w/apps/tilecache-2.11/tmp/tilecache

 

# [layername] --all other sections are named layers

#

#type={MapServerLayer,WMSLayer}

#   *** if you want to use MapServerLayer, you*must* have Python mapscript

#       installed and available ***

#

#srs=EPSG:4326                     ***defaults to EPSG:4326           ***

# levels=20                         *** defaults to 20zoom levels      ***

#metaTile=true                     ***metatiling off by default

#metaBuffer=10                     ***size of metatile buffer in px   ***

#                      *** but you may want toset extension=png8 for   ***

#                      *** GeoServer WMS, andthis lets you set the     ***

#                      *** mime_typeseperately.                        ***

 

# The followingis a demonstration of a layer which would be generated

# according tothe 'Google projection'. This uses the standard values for

# a sphericalmercator projection for maxextent, maxresolution, units

# and srs.

# url=http://localhost/cgi-bin/mapserv?map=/mapdata/world.map

# layers=world

8.       配置环境变量，我的电脑---右键--属性--高级--环境变量--下边框的系统变量，先在path中添加上C:\Python25，然后再在pythonpath（大写）中添加C:\tilecache-2.10，确定确定

安装好python后，环境变量中自己就有PYTHONPATH，值为：

D:\Program Files\ArcGIS\bin;C:\ms4w\apps\tilecache-2.11

9.      最后，"运行"，输入"Regedit"，打开注册表编辑器，在注册表的[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.5\PythonPath]位置下的“默认”键值中添加TileCache的位置"C:\tilecache\"

10.   测试结果：启动apache http server，输入：http://localhost:8080/tilecache/tilecache.py?LAYERS=basic&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-180,-90,0,90&WIDTH=256&HEIGHT=256，有图片显示，说明配置成功。

只需用改端口号即可，结果如下，是一个图片：

查看缓存内容如下：

最后，修改tilecache目录下的index.html文件内容，只改一个后缀名，因为tilecache的后缀名被改为了py，所以相应改动如下：

 layer = new OpenLayers.Layer.WMS( "VMap0", 
                    "tilecache.py?", {layers: 'basic', format: 'image/png' } );

然后在浏览器访问 http://localhost:8080/tilecache/index.html

即可看到瓦片地图

在瓦片缓存目录下可以看到切片和目录结构如下

接下来配置tilecache.cfg，加入本地的postgis图层
