ubuntu linux环境下,按照网址(https://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/提供的方式,执行至sudo /etc/init.d/renderd restart
打开http://localhost/osm/slippymap.html就可以看到样例图;但是如果不出意外,中文会出现方框,无法正常显示。
下面说明解决方法:
- 1)安装unifont字体
sudo apt-get install unifont
- 2)修改/etc/mapnik-osm-data/inc/fontset-settings.xml.inc的内容为:
<!--Settings for Mapnik Fonts
To see the fonts you have installed with Mapnik do:
ls `python -c "import mapnik;print mapnik.fontscollectionpath"`-->
<FontSet name="book-fonts">
<Font face-name="unifont Medium" />
</FontSet>
<FontSet name="bold-fonts">
<Font face-name="unifont Medium" />
</FontSet>
<FontSet name="oblique-fonts">
<Font face-name="unifont Medium" />
</FontSet>
修改/etc/renderd.conf的内容为:
[renderd]
stats_file=/var/run/renderd/renderd.stats
socketname=/var/run/renderd/renderd.sock
num_threads=4
tile_dir=/var/lib/mod_tile ; DOES NOT WORK YET
[mapnik]
plugins_dir=/usr/lib/mapnik/2.0/input
font_dir=/usr/share/fonts/truetype/unifont
font_dir_recurse=true
[default]
URI=/osm/
XML=/etc/mapnik-osm-data/osm.xml
DESCRIPTION=This is the standard osm mapnik style

- 3)修改/etc/mapnik-osm-data/osm.xml的关键词,把配置文件中的FontSet name="bold-fonts"等字体集设置全部改为字符类型设置face-name="unifont Medium"。
- 4)删除缓存文件 sudo rm -rf /var/lib/mod_tile/default/*
再次打开,中文名称应该就可以正常显示了。
附加:
可以根据如下命令的运行情况,来判断mapnik是否正确运行。
sudo su www-data
