1.如是Apache服务器，操作如下：
建立.htaccess文件，在该文件里面写入如下伪静态规则：
# 将 RewriteEngine 模式打开
RewriteEngine On
# 修改以下语句中的 /discuz 为你的论坛目录地址，如果程序放在根目录中，请将 /discuz 修改为 /
RewriteBase /discuzxx
# Rewrite 系统规则请勿修改
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^topic-(.+)\.html$ portal.php?mod=topic&topic=$1&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^article-([0-9]+)-([0-9]+)\.html$ portal.php?mod=view&aid=$1&page=$2&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^forum-(\w+)-([0-9]+)\.html$ forum.php?mod=forumdisplay&fid=$1&page=$2&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^thread-([0-9]+)-([0-9]+)-([0-9]+)\.html$ forum.php?mod=viewthread&tid=$1&extra=page\%3D$3&page=$2&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^group-([0-9]+)-([0-9]+)\.html$ forum.php?mod=group&fid=$1&page=$2&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^space-(username|uid)-(.+)\.html$ home.php?mod=space&$1=$2&%1
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^([a-z]+)-(.+)\.html$ $1.php?rewrite=$2&%1
2.如果是IIS6，操作如下：
下载
Discuzx 1.5 Rewrite组件，上传到服务器的根目录，然后在"ISAPI"中加载刚刚上传的Rewrite组件中的Rewrite.dll即可。
或者已经安装了rewrite的朋友
httpd.ini
[ISAPI_Rewrite]
# 3600 = 1 hour
CacheClockRate 3600
RepeatLimit 32
# Protect httpd.ini and httpd.parse.errors files
# from accessing through HTTP
RewriteRule ^(.*)/topic-(.+)\.html(\?(.*))*$ $1/portal\.php\?mod=topic&topic=$2&$4
RewriteRule ^(.*)/article-([0-9]+)-([0-9]+)\.html(\?(.*))*$ $1/portal\.php\?mod=view&aid=$2&page=$3&$5
RewriteRule ^(.*)/forum-(\w+)-([0-9]+)\.html(\?(.*))*$ $1/forum\.php\?mod=forumdisplay&fid=$2&page=$3&$5
RewriteRule ^(.*)/thread-([0-9]+)-([0-9]+)-([0-9]+)\.html(\?(.*))*$ $1/forum\.php\?mod=viewthread&tid=$2&extra=page\%3D$4&page=$3&$6
RewriteRule ^(.*)/group-([0-9]+)-([0-9]+)\.html(\?(.*))*$ $1/forum\.php\?mod=group&fid=$2&page=$3&$5
RewriteRule ^(.*)/space-(username|uid)-(.+)\.html(\?(.*))*$ $1/home\.php\?mod=space&$2=$3&$5
RewriteRule ^(.*)/([a-z]+)-(.+)\.html(\?(.*))*$ $1/$2\.php\?rewrite=$3&$5
如果是IIS虚拟主机，则修对应的httpd.ini文件即可。
然后在"全局"=》"优化设置"=》"搜索引擎优化"中开启相应的伪静态页面即可。
上面Apache,IIS两种环境下的伪静态配置我都成功了。
