Nginx forwarding requests to the wrong Apache/Plesk Virtual Host

Question

server { listen 81; server_name example.com localhost direct1.example.com www.example.com admin.example.com forum.example.com; location /media/ { root /var/www/vhosts/example.com/html; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } location / { proxy_set_header Host $host; proxy_set_header Connection Close; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; root /var/www/vhosts/example.com/html; proxy_pass http://127.0.0.1:80; } } 

This is what I have in nginx/defaults.conf. The server is currently using Apache fine, and Plesk, which seems to manage vhosts on its own (somehow).

Any requests to example.com:81/media/image.jpg work fine, but example.com:81 uses an incorrect vhost.

I'm not 100% sure how the vhost situation works with Plesk, but it was installed and the default vhost is server1.example.com, and no matter how much fiddling with the proxy settings I do, I can't get it to use the example.com vhost.

edit added a ; to the root line under location. It was missing, I tried adding it but still no luck.

update added ServerName "example.com" to /etc/httpd/conf.d/zz010_psa_httpd.conf. Now under apache-status, it lists the vhost as example.com, but still "uses" server1.example.com. Boo.

It also seems that it's using DocumentRoot from the main apache httpd.conf, and not using the proper virtual host.

From the nginx docs on proxy_pass:

Note that the HTTP Host header is not forwarded, but is set based on the proxy_pass statement.

This means your proxy_set_header Host $host; line has no effect. The actual Host header passed to Apache will be Host: 127.0.0.1 as per the proxy_pass statement.

I recommend this location / section to proxy as you described:

location / { proxy_set_header Connection Close; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://example.com:80; }
