1.　在需要使用.htaccess文件的目錄下新建一個.htaccess文（wén）件

這個.htaccess文件一般discuz、dedecms等係統都自帶

# .htaccess rewrite rule
rewrite ^(.*)/archiver/((fid|tid)-[w-]+.html)$ $1/archiver/index.php?$2 last;
rewrite ^(.*)/forum-([0-9]+)-([0-9]+).html$ $1/forumdisplay.php?fid=$2&page=$3 last;
rewrite ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+).html$ $1/viewthread.php?tid=$2&extra=page%3D$4&page=$3 last;
rewrite ^(.*)/profile-(username|uid)-(.+).html$ $1/viewpro.php?$2=$3 last;
rewrite ^(.*)/space-(username|uid)-(.+).html$ $1/space.php?$2=$3 last;
rewrite ^(.*)/tag-(.+).html$ $1/tag.php?name=$2 last;
# end .htaccess rewrite rule

2.然後修（xiū）改nginx.conf，在（zài）需（xū）要添加偽靜態的虛擬主機的server{}中引入.htaccess文件（jiàn）

server{
include xxxx/.htaccess; ##(把這個改成你.htaccess文件的具體位置)
}

重啟nginx.conf即可。
