Nginx Tips

Multi Level SubDirectory Setup which is not a multisite.

If a multilevel subdirectory install is required , make sure /dir/mappedsite is a symbolic link . For single level the rewrite is not required. Also make sure that safe path is updated accordingly.

# If subdirectory is there match files inside the subdirectory 
location /de/fernstudium {
        index index.php index.html index.htm;
        try_files $uri $uri/ /de/fernstudium/index.php?q=$uri&$args;
    }

# So that /de is not matched as a domain 
rewrite ^/de(.?!(fernstudium)*)$ $1 last;

Subdirectory Setup with reverse proxy

This is used when the subdirectory is on a different server. wordpress homeurl and siteurl also to be updated.

location ~/news(.*)$ {
            proxy_set_header X-Real-IP  $remote_addr;
            proxy_set_header X-Forwarded-For $remote_addr;
            proxy_set_header Host news.erudera.com;
            proxy_pass http://172.104.155.54:80$1$is_args$args;
