phpcms在nginx的rewrite伪静态标准写法

我用的lnmp一键安装包，conf文件是放在默认路径。在进行测试时，我先使用了：

location / {
rewrite ^/caipu-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=show&catid=$1&id=$2&page=$3 last;
rewrite ^/content-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=show&catid=$1&id=$2&page=$3 last;
rewrite ^/list-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=lists&catid=$1&page=$2 last;
rewrite ^/tag-([^.]*)-([0-9]+)-([0-9]+).html /index.php?m=content&c=tag&catid=$2&tag=$1&page=$3 last;
rewrite ^/comment-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=comment&c=index&a=init&commentid=content_$1-$2-$3 last;
rewrite ^/([^.]*).html /index.php?m=member&c=index&a=$1 last;
}

然后就出现杯具了。打开网站首页时提示“Action does not exist.”意思是行为不存在？我翻遍了百度，在phpcms官方论坛有人说这个错误是地址问题，再联想到我是修改伪静态出现的······我懂了，是首页伪静态问题！

在我对照了wordpress官方的写法后，将上面的规则改成：

location / {
if (!-f $request_filename){
rewrite (.*) /index.php;
}
rewrite ^/caipu-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=show&catid=$1&id=$2&page=$3 last;
rewrite ^/content-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=show&catid=$1&id=$2&page=$3 last;
rewrite ^/list-([0-9]+)-([0-9]+).html /index.php?m=content&c=index&a=lists&catid=$1&page=$2 last;
rewrite ^/tag-([^.]*)-([0-9]+)-([0-9]+).html /index.php?m=content&c=tag&catid=$2&tag=$1&page=$3 last;
rewrite ^/comment-([0-9]+)-([0-9]+)-([0-9]+).html /index.php?m=comment&c=index&a=init&commentid=content_$1-$2-$3 last;
rewrite ^/([^.]*).html /index.php?m=member&c=index&a=$1 last;
}
