503 service unavailable after installing php-fpm with apache and nginx reverse proxy

Question

I have installed apache on centos 7 and setup nginx as a reverse proxy for apache. Apache listens into 8080 and nginx into 80 . I have two virtual hosts and also two server blocks.

Everything is OK and I can see my two server addresses: www1.mysite.com and www2.mysite.com

Now I install php-fpm to run php script . Near to one of my tested index.html files in my websites' root directory , I create an info.php file to see something printed by php. But I encounter a 503 error (unavailable service). What is wrong with my simple configuration do you think?

Any idea or similar experience would help me. Thank you in advance

Answer 1

My problem was almost funny. I had named my sock file php-fpm.sock but it was another name in the php-fpm config file. I made them equal and the problem was resolved. Hope nobody encounter this rediculous mistake.
