linux – logrotate不写日志到正确的文件

Linux 前端之家
前端之家收集整理的这篇文章主要介绍了linux – logrotate不写日志到正确的文件，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我有一个生产系统,托管有多个Nginx应用程序.那些是Nginx应用服务器.现在,对于这些Nginx app服务器中的每一个,都会在/etc/logrotate.d/文件夹中配置logrotate配置文件.下面给出了logrotate配置文件的一个示例. 
/var/www/example/current/log/example.log {
  daily
  missingok
  rotate 1
  delaycompress
  compress
  notifempty
  copytruncate
}

我检查了Logrotate not working并检查了我的配置,并没有找到任何重复的应用程序服务器或Nginx条目.下面是我的Nginx logrotate文件的定义.

/var/log/Nginx/*.log {
    daily
    missingok
    rotate 3
  compress
  delaycompress
    notifempty
    create 0640 www-data adm
    sharedscripts
    postrotate
    if [ -s /var/run/Nginx.pid ]; then
      kill -USR1 `cat /var/run/Nginx.pid`
    fi
    endscript
}

我的日志仍然是用* .log.1编写而不是* .log任何人都可以帮忙吗？我想知道这里有什么问题.
以下是调试模式下的logrotate命令输出.

logrotate --force -d /etc/logrotate.d/Nginx
reading config file /etc/logrotate.d/Nginx

解决方法

如果Nginx正在写入旧日志文件,则可能会发生这种情况,因为您的postrotate操作无效.

您是否检查/var/run/Nginx.pid是否存在且包含正确的pid？

而且你可以试试

logrotate --force -d /etc/logrotate.d/Nginx

然后检查输出.它给出了很好的指示.
