管理员登录到后台，选择“全局-SEO设置-URL静态化”，可以看到有“页面 标记 格式 可用”几个标题，将可用下面的方框里都选中，Rewrite兼容性选否，点击提交。
找到nginx配置文件中配置这个bbs域名的server段，在location /内添加伪静态规则。
比如原来是：
...
server {
listen 80;
server_name www.aaa.com;
access_log /var/log/nginx/aaa.com.log main;
location / {
root /home/webroot;
index index.html index.htm index.php;
}
}
...
修改后为：
...
server {
listen 80;
server_name www.aaa.com;
access_log /var/log/nginx/aaa.com.log main;
location / {
root /home/webroot;
index index.html index.htm index.php;
