Apache htaccess rules converting to Nginx rules - apache

Question

I need to translate some htaccess rules for the nginx server,
my htaccess was:
RewriteEngine On
RewriteBase /mysite
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /mysite/index.php/$1 [L]
SetOutputFilter DEFLATE
<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
</ifModule>
i've translated this part
RewriteEngine On
RewriteBase /mysite
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /mysite/index.php/$1 [L]
that looks like
if (!-f $request_filename){
set $rule_0 1$rule_0;
}
if (!-d $request_filename){
set $rule_0 2$rule_0;
}
if ($rule_0 = "21"){
rewrite ^/(.*)$ /mysite/index.php/$1 last;
}
is it ok?
Then I need to translate the second part of the htaccess (showed above).
How can I translate that?

Answer 1

if (!-f $request_filename){
set $rule_0 1$rule_0;
}
if (!-d $request_filename){
set $rule_0 2$rule_0;
}
if ($rule_0 = "21"){
rewrite ^/(.*)$ /bitfungus/index.php/$1 last;
}
is it ok?`
No, it's ugly. Nginx isn't apache, you should not use rewrites where you don't actually need them (in about 95% cases you don't need rewrites in nginx).

Correct:
try_files $uri $uri/ /bitfungus/index.php$uri;
