;       will be used.
; RPM: apache user chosen to provide access to the same directories as httpd
user = apache
; RPM: Keep a group allowed to write in log dir.
group = apache
…

改为
…
; RPM: apache user chosen to provide access to the same directories as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx
…


------------------------------------------------------
listen = 127.0.0.1:9000;

改为
listen = /var/run/php-fpm/php-fpm.sock;

找到此行改为
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

启动php-fpm服务

    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
