Question

我在ubuntu上有mapcache，mapserver（WMS），nginx。我的指示：

    http://mapserver.org/id/mapcache/install.html#cgi-fastcgi-specific-instructions

Nginx * .conf：

    location ~ ^/maps/ofp_10000(?<path_info>/.*|$) {
        set $url_prefix "/maps/ofp_10000";
        mapcache /mapcache/ofp.xml;
        error_page 404 = @fastcgi_mapcache;
    }

   location @fastcgi_mapcache {
        fastcgi_pass 127.0.0.1:9001;
        fastcgi_index mapserv;
        fastcgi_param QUERY_STRING   map=/ofp_10000/vrt_all.map&$query_string;
        fastcgi_param REQUEST_METHOD $request_method;
        fastcgi_param CONTENT_TYPE   $content_type;
        fastcgi_param CONTENT_LENGTH $content_length;
        fastcgi_param SERVER_NAME    $server_name;
        fastcgi_param SERVER_PORT    $server_port;
        fastcgi_param PATH_INFO      $path_info;
        fastcgi_param SCRIPT_NAME    "/maps/ofp_10000";
     }

ofp.xml：

   <mapcache>
         <cache name="tmp1" type="disk" layout="template">
                <template>/tmp/mapcache/{tileset}#{grid}#{dim}/{z}/{x}/{y}.{ext}</template>

  </mapcache>

在

  http://host/maps/ofp_10000/demo/wms

我的WMS工作正常，但没有缓存 - / tmp / mapcache是空的。

工作，错误的指令，需要启动mapcache.fcgi并在nginx中配置，如：

    location ~ ^/mapserver/ofp_10000(?<path_info>/.*|$) {
            fastcgi_pass 127.0.0.1:9001;
            fastcgi_index mapserv;
            fastcgi_param QUERY_STRING   map=/ofp_10000/vrt_all.map&$query_string;
            fastcgi_param REQUEST_METHOD $request_method;
            fastcgi_param CONTENT_TYPE   $content_type;
            fastcgi_param CONTENT_LENGTH $content_length;
            fastcgi_param SERVER_NAME    $server_name;
            fastcgi_param SERVER_PORT    $server_port;
            fastcgi_param PATH_INFO      $path_info;
            fastcgi_param SCRIPT_NAME    "/maps/ofp_10000";
    }

    location ~ ^/maps/ofp_10000(?<path_info>/.*|$) {
            set $url_prefix "/maps/ofp_10000";
            mapcache /usr/local/share/mapcache/ofp.xml;
            error_page 404 = @fastcgi_mapcache;
    }

    location @fastcgi_mapcache {
            fastcgi_pass 127.0.0.1:9002;
            fastcgi_param QUERY_STRING $query_string;
            fastcgi_param REQUEST_METHOD $request_method;
            fastcgi_param CONTENT_TYPE   $content_type;
            fastcgi_param CONTENT_LENGTH $content_length;
            fastcgi_param PATH_INFO      $path_info;
    }

和mapcache init.d：

              #! /bin/sh
               if [ "$NETWORKING" = "no" ]
                then
                       exit 0
               fi
               PREFIX=/usr
               NAME=mapcache
                PID=/var/run/mapcache.pid
                DAEMON=$PREFIX/bin/spawn-fcgi
                DAEMON_OPTS=" -a 127.0.0.1 -p 9002 -F 4 -u www-data -U www-data -P $PID $PREFIX/local/bin/mapcache.fcgi"
                MAPCACHE_CONFIG_FILE=/usr/local/share/mapcache/ofp.xml
             start () {
                        export MAPCACHE_CONFIG_FILE=$MAPCACHE_CONFIG_FILE
                         echo -n $"Starting $NAME "
                         exec $DAEMON $DAEMON_OPTS >> /dev/null
                         daemon --pidfile $PID
                        RETVAL=$?
                          echo
                       [ $RETVAL -eq 0 ]
             }
             stop () {
                     echo -n $"Stopping $NAME "
                     killproc -p $PID
                      #make sure all mapservers are closed
                    pkill -f mapcache.fcgi
                    RETVAL=$?
                     echo
                    if [ $RETVAL -eq 0 ] ; then
                          rm -f $PID
                    fi
            }
            restart () {
               stop
               start
            }

            if [ -f /lib/lsb/init-functions ]; then
              . /lib/lsb/init-functions
            elif [ -f /etc/init.d/functions ]; then
              . /etc/init.d/functions
            fi
            # See how we were called.
           case "$1" in
               start)
                    start
                   ;;
               stop)
                     stop
                     ;;
               status)
                    status lt-mapserv
                    RETVAL=$?
                  ;;
               restart)
                  restart
                 ;;
              *)
                    echo $"Usage: $0 {start|stop|status|restart}"
                      RETVAL=2
                       ;;
            esac
           exit $RETVAL

和ofp.xml更改网址：

              <source name="vmap0" type="wms">
               <getmap>
                  <params>
                     <FORMAT>image/png</FORMAT>
                      <LAYERS>vrt_all</LAYERS>
                     <MAP>/ofp_10000/vrt_all.map</MAP>
                  </params>
                </getmap>

                 <http>
                      <url>http://host/mapserver/ofp_10000?</url>
