本配置示例在ThinkPHP5 环境下亲测有效，二级目录配置与根目录配置完全独立。主要是通过 ^~ 把sub路径的路由全部接收过来，然后在子location里面进行二次路由和解析，比较方便灵活。之前一直以为location是不能嵌套的，通过这次实践，发现这样用的好处了，确实很方便。
server {
listen 80 ;
index index.php index.html;
location ^~ /sub/ {
set $subroot /home/peaksite/public/;
alias $subroot;
if ( !-e $request_filename) {
rewrite ^/sub/(.*)$ /sub/index.php/$1 last;
break;
}
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
set $scriptname ‘‘;
set $pathinfo ‘‘;
if ( $uri ~ ^/sub/(.+\.php)($|/.+) ) {
set $scriptname $1;
set $pathinfo $2;
}
fastcgi_param SCRIPT_FILENAME $subroot/$scriptname;
fastcgi_index index.php?IF_REWRITE=1;
fastcgi_param PATH_INFO $pathinfo;
fastcgi_param SCRIPT_FILENAME $subroot/$scriptname;
include fastcgi_params;
}
}
}
