Então eu tenho essa configuração para meu wordpress.
Todos os servidores rodam em Centos 7 MariaDB 10.4.17 Php-FPM 7.4 PHP 7.4 NginX
Servidor 1, o servidor Front Load Balancing Servidor 2-3-4 o aplicativo wordpress servido com NginX Server 4 MariaDB
A configuração do balanceamento de carga do Nginx funciona bem com o info.php padrão em cada servidor 2-3-4. Eles trocam usando o round robin.
O wordpress por si só funciona bem no servidor 2-3-4. Eu tenho que alterar o URL do site e o URL inicial do wordpress no banco de dados wp-options para refletir o endereço IP do servidor. Por exemplo, se estou testando o servidor wp 2, o URL do site e o URL inicial são apontados para o servidor 2.
No segundo em que combinei todos os servidores 2-3-4 no LB com o wordpress, recebi este erro "A página não está redirecionando corretamente". Não tenho certeza se há certas configurações que precisam ser feitas para que o WP funcione no balanceador de carga Nginx. Algum conselho é como resolver o problema? Por favor ajude?
