Update to index.php in observium to work with nginx.

Change from:

$_SERVER[‘PATH_INFO’] = (isset($_SERVER[‘PATH_INFO’]) ? $_SERVER[‘PATH_INFO’] : $_SERVER[‘ORIG_PATH_INFO’]);

Change to:

$_SERVER[‘PATH_INFO’] = $_SERVER[‘REQUEST_URI’];

nginx site configuration:

server {
listen 80;
server_name hostname.kulish.com;

access_log /var/log/nginx/hostname.kulish.com.acc.log;
error_log /var/log/nginx/hostname.kulish.com.err.log;

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

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

location / {
try_files $uri $uri/ @observium;
}

location @observium {
rewrite ^(.+)$ /index.php/$1/ last;
}

}

# General php settings
include php.conf;

# We need to exclude robots.txt specifically
include drop.conf;

php.conf contents:

location ~ \.php {

fastcgi_pass unix:/var/run/php5-fpm/php5-fpm.sock;
}

I am connecting to a php5-fpm socket to avoid TCP overhead.

drop.conf contents:

# Drop from logging and accidental access
