wordpress下开启防垃圾评论功能

最近blog好多垃圾评论,于是打算开启Akismet,才发现Akismet是要连接外网服务器的,sf空间不支持,没办法,只能安装math-comment-spam-protection了,它是以算数这种方式来anti spam的!下面是设置步骤:
wget http://downloads.wordpress.org/plugin/math-comment-spam-protection.3.0.zip
unzip math-comment-spam-protection.3.0.zip
mv math-comment-spam-protection /home/project-web/your-project-name/htdocs/wp-content/plugins/
然后在后台开启即可!
