Nginx: multiple sites (including Wordpress) in multiple folders with droplet_ip/site_name as URL

Hello, I have a LEMP droplet on which I want to host few sites. For now I have two applications: PhpMyAdmin and a Wordpress site. But my Wordpress site is stored in “/srv/www/mysite/mysite/src” and I want to access to this site via the URL “x.x.x.x/mysite” (x.x.x.x is my droplet IP of course) because I can’t use a domain name for the moment. So I tried a lot of things (with locations, aliases, root…) but none has worked. My last config file (works for PhpMyAdmin but not for “mysite”):

server {
	listen 80;
	listen [::]:80;

	root /srv/www;
	index index.php index.html;

	# Hosts
	server_name localhost x.x.x.x;

	location / {
		try_files $uri $uri/ /index.php?$args;
	}

	location /mysite/ {
		alias /srv/www/mysite/mysite/src;
	}

	error_page 404 /404.html;
	error_page 500 502 503 504 /50x.html;
	location = /50x.html {
		root /usr/share/nginx/html;
	}

	location ~ \.php$ {
		try_files $uri =404;
		fastcgi_split_path_info ^(.+\.php)(/.+)$;
		fastcgi_pass unix:/var/run/php5-fpm.sock;
		fastcgi_index index.php;
		include fastcgi_params;
	}
}

As I said I’ve made a lot of tests and none of them has worked (there are always errors 404 and 500)… So thanks in advance for your help! :-)
