Here is how you can switch PHP-FPM to listen on a unix socket rather than a TCP socket. This guide assumes you have already installed a LEMP stack as shown in Install LEMP on Centos.
Switch PHP-FPM Listen On Unix Socket
Step 1. First, edit the file at /etc/php-fpm.d/www.conf and find this block:
1 2 3 4 5 6 7 8 9 10 | ;TheaddressonwhichtoacceptFastCGIrequests. ;Validsyntaxesare: ; 'ip.add.re.ss:port' -tolistenonaTCPsockettoaspecificaddresson ; aspecificport; ; 'port' -tolistenonaTCPsockettoalladdressesona ; specificport; ; '/path/to/unix/socket'-tolistenonaunixsocket. ;Note:Thisvalueismandatory. ;listen=127.0.0.1:9000 listen=/var/run/php5-fpm.sock |
Step 2. Next, let’s create a file at /etc/nginx/conf.d/ named php5-fpm.conf:
1 2 3 | upstreamphp5-fpm-sock{ serverunix:/var/run/php5-fpm.sock; } |
Step 3. Open Nginx virtual-host config file(s), In our Nginx server config we’ll also have to change where to pass PHP requests:
1 2 | #fastcgi_pass 127.0.0.1:9000; fastcgi_passphp5-fpm-sock; |
Step 4. Reload php-fpm and nginx.
1 2 | servicephp-fpmrestart servicenginxrestart |
