php-fpm running status monitoring

PHP-FPM has a built-in status page. After opening, you can view the detailed running status of PHP-FPM, which can help PHP-FPM optimization.

1. Open php-fpm.conf and configure the php-fpm status page options:

pm.status_path = /phpfpm_status     //'phpfpm_status' can be customized

 2. Configure nginx.conf and add server

server {

    listen 80;
    server_name 127.0.0.1;  #或域名

    location /phpfpm_status {
        fastcgi_pass 127.0.0.1:9000;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
    }
}

3. Restart or reload nginx and php-fpm

1. service php-fpm restart
2. service nginx restart
