LogRotate：运行非共享后旋转脚本时出错

Question

在每日日志轮转期间，我们收到以下错误。

/usr/bin/find: cannot delete ‘/var/log/tomcat/catalina.out’: Permission denied error: error running non-shared postrotate script for /var/log/tomcat/xdlogger.log of '/var/log/tomcat/*.log'

这是我的 logrotate 配置。

# cat /etc/logrotate.d/tomcat
/var/log/tomcat/*.txt
/var/log/tomcat/*.log
/var/log/tomcat/catalina.out {
    copytruncate
    daily
    dateext
    rotate 3
    compress
    missingok
    postrotate
        /usr/bin/find /var/log/tomcat/ -type f ! -name 'catalina.out' -mtime +5 -delete
    endscript
}

catalina.out 和 xdlogger.log 的权限如下。

# stat /var/log/tomcat/catalina.out
  File: `/var/log/tomcat/catalina.out'
