How to use switch PHP(using phpbrew) version in nginx config

phpbrew-config.md

php -v
PHP 5.6.3 (cli) (built: Oct 28 2015 09:47:41)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2014 Zend Technologies

But this only changes in CLI. You have to tweak you nginx(same for apache) to make it works. Nginx will still using the native PHP-FPM.

> ps aux | grep php-fpm
user     17093  0.7  2.5 512976 26080 ?        Ss   13:40   0:00 php-fpm: master process (/etc/php-fpm.conf)

> phpbrew fpm start

To know which port our phpbrew fpm uses, we can check from ~/.phpbrew/php/php-5.6.3/etc/php-fpm.conf

...
; The address on which to accept FastCGI requests.
...
; Note: This value is mandatory.
listen = 127.0.0.1:9000

Ok it's 127.0.0.1:9000. So in our nginx configuration, we do something like:

server {
 ...
 
   location ~ \.php$ {
    try_files       $uri =404;
    #fastcgi_pass    unix:/var/run/php-fpm/php-fpm.sock;        <--- probably default setting
    fastcgi_pass     127.0.0.1:9000;            <--- changed this
    fastcgi_index   index.php;
    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include         fastcgi_params;
  }
}

My system seems to be slightly different.
I looked in ~/.phpbrew/php/php-7.2.8/etc/php-fpm.d/www.conf
there I found

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
;                            a specific port;
;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses
;                            (IPv6 and IPv4-mapped) on a specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /home/cparrish/.phpbrew/php/php-7.2.8/var/run/php-fpm.sock

So I updated my config file to read.

location ~\.php$ {
                #fastcgi_pass    unix:/run/php-fpm/www.sock;
                fastcgi_pass    unix:/home/cparrish/.phpbrew/php/php-7.2.8/var/run/php-fpm.sock;
                fastcgi_index   index.php;
                fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
                fastcgi_read_timeout 380;
                include         fastcgi_params;
        }

Then I restarted nginx
and when I go to the page I get a 502 Bad Gateway error. So I checked my log and saw the following

 [crit] 9473#0: *10294 connect() to unix:/home/cparrish/.phpbrew/php/php-7.2.8/var/run/php-fpm.sock failed (13: Permission denied) while connecting to upstream, client: x.x.x.x, server: www.xxx.xxx, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://unix:/home/cparrish/.phpbrew/php/php-7.2.8/var/run/php-fpm.sock:", host: "www.xxx.xxx"

So I checked my permissions and got the following any ideas?

total 4.0K
-rw-r--r--. 1 cparrish cparrish 4 Aug 11 11:15 php-fpm.pid
srw-rw----. 1 cparrish cparrish 0 Aug 11 11:15 php-fpm.sock

I'm not sure what to try next.

Never mind I changed it to use a tcp socket like you had in your example and it's working fine now.
