设置Nginx重定向规则优先级

Question

I have nginx+php-fpm and some rewrite rules for sef-urls.

The problem is that all my custom redirects/rewrites are ignored and request going to php script instead redirecting.

Part for sef-links:

if ($request_filename !~ ".(png|gif|ico|swf|jpe?g|js|css)$"){
        set $rule_0 1$rule_0;
}   
if (!-f $request_filename){
        set $rule_0 2$rule_0;
}   
if (!-d $request_filename){
        set $rule_0 3$rule_0;
}   
if ($rule_0 = "321"){
        rewrite /. /index.php?sef_rewrite=1 last;
}   

And I want to do that redirect:

location = /first.html {
    return 301 /second.html;
    }

You need to thing in terms of nginx's locations and rules. Then it will be much easier to write proper config. Try this one:

location / {
    # replacement for last three `if`s
    try_files $uri $uri/ /index.php?sef_rewrite=1;
}

# here is you redirect
location = /first.html {
    return 301 /second.html;
}

# this is replacement for first `if`
location ~ \.(png|gif|ico|swf|jpe?g|js|css)$ {
    # serve static files
}

# I'm sure you have this block somewhere
location ~ \.php$ {
    # serve php
}
