logrotate permission denied

Question

Por que estou recebendo permissão para renomear meu arquivo de registro ao executar logrotate ? O proprietário do meu arquivo de log mostrado abaixo é rajohns , que é o mesmo usuário que efetuou login executando o comando logrotate mostrado abaixo.

$ cat /etc/logrotate.d/judgecard-api-0.0.1

/var/log/judgecard-api-0.0.1.log {
    su rajohns rajohns
    weekly
    rotate 4
    create 0777 rajohns rajohns
    missingok
    notifempty
    postrotate
        systemctl restart judgecard-api-0.0.1.service > /dev/null
    endscript
}

$ ls -l /var/log/judgecard-api-0.0.1.log

-rwxrwxrwx 1 rajohns rajohns 10578 Feb 12 23:01 /var/log/judgecard-api-0.0.1.log

$ sudo logrotate -vf -s ~ / logrotate_test_status_file judgecard-api-0.0.1

Obviamente, a rotação / var / log falha, pois o diretório normalmente pertence à raiz: adm.

Você pode dar uma olhada no Apache e em outros para ver como eles fazem isso.

A maneira usual de fazer isso é criar um subdiretório em / var / log e tornar outro usuário o proprietário dele:

 sudo mkdir /var/log/judgecards
 chown rajohns /var/log/judgecards

Em seguida, mova os registros antigos e crie novos registros do seu aplicativo aqui.
