Eu tenho uma instância nginx que está configurada para acessar log para /var/log/nginx/access.log e erros para /var/log/nginx/errors.log, mas assim que o logrotate é executado a cada semana, o arquivo obtém os movimentos para * .log.1 e o novo arquivo * .log é criado, mas o nginx continua a registrar no arquivo log.1 em vez do novo arquivo .log (e nada é compactado com gzip). A primeira vez que notei isso, foram 3 semanas desde a rotação do log e o log estava ficando enorme. A execução de kill -HUP 'cat /run/nginx.pid'
fez o nginx começar a fazer login no local certo novamente, mas o problema começou novamente na semana seguinte.
A razão mais importante que isso é frustrante é que eu tenho os logs configurados para carregar no Loggly via rsyslog, e quando o nginx para de logar no arquivo eu tenho polls do rsyslog, então as coisas param de fazer upload e eu não recebo nenhum alerta.
Eu suspeito que tenha algo a ver com a reinicialização do nginx ou o recarregamento da configuração, porque ele não foi iniciado até que eu tivesse feito uma alteração de configuração e recarregado a configuração de uma forma que achei normal. Eu tentei executar kill -USR1 'cat /run/nginx.pid'
, mas os arquivos continuaram a ser registrados no local errado até que eu corri kill -HUP 'cat /run/nginx.pid'
, o que eu já sei que não resolve o problema.
Alguma ideia do que está acontecendo? Eu admito que não sou especialista em administração de logrotate ou nginx, mas meus googles me falharam nessa.
Aqui está o meu script nginx logrotate, e me avise se houver algo mais que você queira ver. O nginx.conf não tem nada de especial em relação ao registro, além de definir os locais de saída.
/var/log/nginx/*.log {

EDIT: Acho que encontrei o problema. Aqui está a saída da execução do logrotate no modo de depuração:
