mapserver+QGIS+openlayers的安装和配置

1、下载MS4W，不要怀疑MS4W就是mapserver，只是里面集成了一些其他的工具和库，下载地址：http://www.maptools.org/ms4w/index.phtml?page=downloads.html下载zip就行。

2、将下载的zip解压到硬盘，最好是根目录，不然还要配置其他参数，很麻烦。

3、在dos窗口下执行ms4w文件夹下的apache-install.bat

4、打开浏览器输入http://localhost/或者http://127.0.0.1/ 将可以看到MS4W的首页面。这样mapserver就安装成功了

5、测试mapserver是否支持WMS服务，使用DOS命令行进入MS4W的安装路径（如D:ms4wApachecgi-bin），执行mapserv -v

6、下载安装QGIS，地址：http://www.qgis.org/en/site/，QGIS为了生成mapserver要用的mapfile

7、安装好后在插件>Manage Plugins下添加Mapserver Export插件

8、打开几个shp图层，右击每个图层，在属性中设置使用oldsymbology,否则出错

9、设置好后，导出mapfile文件，一般情况下这个文件不能直接用，需要配置一下，配置的方法自己百度吧

10.配好后在浏览器中输入：http://192.168.1.100/cgi-bin/mapserv.exe?MAP=C:/ms4w/Apache/htdocs/map/ChinaBasint.map&LAYERS=ALL&MODE=MAP

就会出现下图：

11、下一步就是把地图嵌入到openlayers的框架内

将openlayers文件夹内的img，theme，OpenLayers.js三个文件复制到C:ms4wApachehtdocs目录下

这里内容很多，大家可以研究下openlayers自带的例子，通过例子来学习

                map.addLayer(layer);
                layer = new OpenLayers.Layer.WMS( "1 buffer: OpenLayers WMS",
                        "http://vmap0.tiles.osgeo.org/wms/vmap0",

                layer = new OpenLayers.Layer.WMS( "4 buffer: OpenLayers WMS",

                map.addLayer(layer);
                map.addControl(new OpenLayers.Control.LayerSwitcher());
                map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
            }

上面是一个很简单的例子，我们发布自己的地图时，可以把下面的代码段改一下就行了

 layer = new OpenLayers.Layer.WMS( "0 buffer: OpenLayers WMS",
                        "http://vmap0.tiles.osgeo.org/wms/vmap0",
                        {layers: 'basic'}, {'buffer':0} );

下面是我的

Basint =new OpenLayers.Layer.WMS("盆地分布", "http://192.168.1.100/cgi-bin/mapserv.exe?",
        {map:'C:/ms4w/Apache/htdocs/map/ChinaBasint.map',layers:'Basint',transparent: "true"} );
