我有一个生产系统，上面托管了多个 nginx 应用。这些是 nginx 应用服务器。现在，对于每个 nginx 应用服务器，都在/etc/logrotate.d/文件夹中配置了一个 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不工作并检查了我的配置，没有发现应用程序服务器或 nginx 的任何重复条目。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
}
我的日志仍然被写入*.log.1，但没有被写入。*.log有人能帮忙吗？我想了解这里出了什么问题。以下是调试模式下的 logrotate 命令输出。

答案1
如果 nginx 正在写入旧日志文件，则可能是因为您的 postrotate 操作不起作用。
您是否检查过 /var/run/nginx.pid 是否存在且包含正确的 pid？
此外你可以尝试
logrotate --force -d /etc/logrotate.d/nginx
然后检查输出。它给出了很好的指示。
答案2
如果您正在使用 syslog 或 syslog-ng，则需要确保类似这样的内容是共享的 postrotate 脚本的一部分：
sharedscripts
postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
endscript
syslog 将文件写入 inode，而不是文件名，因此如果您不退回 syslog，它将继续写入相同的 inode（即使文件名已更改）对 syslog 进程执行 HUP 操作会将 inode 重置为正确的名称。这与 syslog 无法写入不存在的文件的原因相同。您必须在启动 syslog 之前触摸该文件，以便确定该文件的 inode。
希望有帮助
