o que preciso fazer para que minha web volte ao normal.

    

Answer 1

Você tem uma opção de configuração inválida, e é por isso que o Apache não pode ser iniciado e porque diz 'configtest' failed . Na verdade, a leitura da saída de systemctl status geralmente é suficiente para identificar esses problemas e identificar os principais motivos pelos quais o seu software não está sendo executado corretamente. Eu vejo isso o tempo todo.

Dito isto, este é o erro específico, conforme detalhado na sua saída de status systemctl :

Nov 11 15:42:06 sd-101534 apache2[7132]: AH00526: Syntax error on line 12 of /etc/apache2/mods-enabled/mpm_prefork.conf:
Nov 11 15:42:06 sd-101534 apache2[7132]: Invalid command 'MazClients', perhaps misspelled or defined by a module not included in the server configuration

Edite o arquivo que ele faz referência ( /etc/apache2/mods-enabled/mpm_prefork.conf ) e tente substituir MazClients por MaxClients e tente iniciar o Apache novamente. Parece-me que o seu problema real é com o MPM Prefork e não com o MySQL.
