Nginx, php variable?

Question

PHP

There is a task: php gives a variable and nginx needs to take this variable and insert it into proxy_pass, how can I implement this? And how should I give php this variable so that nginx can process it? Thanks to everyone who helps.

Answer 1

In general, what specific problem are you trying to solve with such manipulations?
Regarding the question, maybe ngx_http_ssi_module will help you .
Or maybe something like this is needed?

Answer 2

Nginx can make requests to memcached and redis. Let nginx take the proxy_pass value from redis.

Answer 3

PHP on apache_mod_php or FastCGI?
For the first case: proxy_set_header will come to $_SERVER['HTTP_*']
For the second case, fastcgi_param will come somewhere in theory, I didn't check it myself.

Answer 4

Keep it simple

And don't ask anything from servers

Answer 5

When changing proxy_pass, nginx also needs to be distorted. Can it be easier to generate a new config (or part of it) for nginx using php?

Answer 6

Measure server load from php, use nginx as a load balancer... Don't you want to look for tools specifically designed to solve such problems? Maybe ipvs, haproxy will suit you?
