nginx写二级目录下安装wordpress多用户版伪静态规则

想在我网站二级目录下“/group/”安装wordpress多用户版，可是wordpress给出的是apache的.haccess规则，如何将.haccess 规则转换为nginx规则。
找了些在线转换工具，转换后都打不开网站。
请教一下两个问题:
1. 二级目录的nginx规则是不是也是写在/a/apps/nginx/vhosts/xxx.com.config文件中。
2. 二级目录多用户wordpress的nginx规则如何写。
麻烦懂这方面的你帮忙指点指点


以下分别是“.haccess规则”和主目录下安装wordpress的nginx规则（用二级域名请自测试，可以实现）。



.haccess规则 RewriteEngine On
RewriteBase /group/ RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L] RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L] RewriteRule . index.php [L]


主目录下安装wordpress多用户版的nginx规则：

# WordPress multisite subdirectory rules.
# Designed to be included in any server {} block.
# This order might seem weird - this is attempted to match last if rules below fail.
# http冒号//wiki点nginx点org/HttpCoreModule
location / {
try_files $uri $uri/ /index.php?$args;
}


# Add trailing slash to */wp-admin requests.
rewrite /wp-admin$ $scheme://$host$uri/ permanent;


# Pass uploaded files to wp-includes/ms-files.php.
rewrite /files/$ /index.php last;


# For multisite: Use a caching plugin that creates symlinks to the correct subdirectory structure to get some performance gains.
set $cachetest "$document_root/wp-content/ms-filemap/${host}${uri}";
if ($uri ~ /$) {
set $cachetest "";
}
if (-f $cachetest) {
# Rewrites the URI and stops rewrite processing so it doesn't start over and attempt to pass it to the next rule.
rewrite ^ /wp-content/ms-filemap/${host}${uri} break;
}


if ($uri !~ wp-content/plugins) {
rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last;
}


# Uncomment one of the lines below for the appropriate caching plugin (if used).
#include global/wordpress-ms-subdir-wp-super-cache.conf;
#include global/wordpress-ms-subdir-w3-total-cache.conf;


# Rewrite multisite '.../wp-.*' and '.../*.php'.
if (!-e $request_filename) {
rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
rewrite ^/[_0-9a-zA-Z-]+.*(/wp-admin/.*.php)$ $1 last;
rewrite ^/[_0-9a-zA-Z-]+(/.*.php)$ $1 last;
}
