Entonces tengo esta configuración para mi WordPress.
Todos los servidores se ejecutan en Centos 7 MariaDB 10.4.17 Php-FPM 7.4 PHP 7.4 NginX
Servidor 1, el servidor de equilibrio de carga frontal Servidor 2-3-4 la aplicación wordpress servida con NginX Servidor 4 MariaDB
La configuración del equilibrio de carga de Nginx funciona bien con info.php estándar en cada uno de los servidores 2-3-4. Cambian de turno usando el round robin.
WordPress por sí solo funciona bien en el servidor 2-3-4. Tengo que cambiar la URL del sitio y la URL de inicio de WordPress en la base de datos de wp-options para reflejar la dirección IP del servidor. Entonces, por ejemplo, si estoy probando el servidor 2 de wp, la URL del sitio y la URL de inicio apuntan al servidor 2.
En el momento en que combiné todos los servidores 2-3-4 bajo LB con WordPress, recibí este error "La página no se redirige correctamente". No estoy muy seguro de si es necesario realizar ciertas configuraciones para que WP funcione bajo el balanceador de carga de Nginx. ¿Algún consejo sobre cómo solucionar el problema? ¿Por favor ayuda?
