centos+Nginx + PHP+mysql，请问我怎么开启rewrite

nginx不用开启rewrite，nginx的重写规则需要写在nginx的conf里面，下面是一些例子

rewrite重写需要写在location里面如

location / {
            rewrite ^/archiver/((fid|tid)-[\w\-]+\.html)$ /archiver/index.php?$1 last;
            rewrite ^/forum-([0-9]+)-([0-9]+)\.html$ /forumdisplay.php?fid=$1&page=$2 last;
            rewrite ^/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ /viewthread.php?tid=$1&extra=page%3D$3&page=$2 last;
            rewrite ^/space-(username|uid)-(.+)\.html$ /space.php?$1=$2 last;
            rewrite ^/tag-(.+)\.html$ /tag.php?name=$1 last;
        }

完整的例子

server
	{
		listen       80;
		index index.html index.htm index.php default.html default.htm default.php;
		root  /data/wwwroot/yiqicms;
                location / {
			if (-f $request_filename/index.html){
                		rewrite (.*) $1/index.html break;
 	       		}
			if (-f $request_filename/index.php){
                		rewrite (.*) $1/index.php;
        		}
			rewrite ^/article\/(.+)\.html$ /article.php?name=$1 last;
rewrite ^/product\/(.+)\.html /product.php?name=$1 last;
rewrite ^/category\/([^/]+)_([0-9]+)[/]? /category.php?name=$1&p=$2 last;
