Logrotate-仅在服务正在运行时重新启动服务

我有一个 HA 集群，其中 samba 在活动节点上运行，现在我在根邮件中收到以下错误：

Can't find pid for destination 'smbd'
error: error running non-shared postrotate script for /var/log/samba/log.smbd of '/var/log/samba/log.smbd '
Can't find pid for destination 'nmbd'
error: error running non-shared postrotate script for /var/log/samba/log.nmbd of '/var/log/samba/log.nmbd '
run-parts: /etc/cron.daily/logrotate exited with return code 1

我可以让 Logrotate 仅在服务正在运行时重新启动它吗？

根据 smane 的要求，logrotate 配置

/var/log/samba/log.smbd {
        weekly
        missingok
        rotate 7
        postrotate
                [ ! -x /usr/bin/smbcontrol ] || /usr/bin/smbcontrol smbd reload-config
        endscript
        compress
        delaycompress
        notifempty
}

/var/log/samba/log.nmbd {
        weekly
        missingok
        rotate 7
        postrotate
                [ ! -x /usr/bin/smbcontrol ] || /usr/bin/smbcontrol nmbd reload-config
        endscript
        compress
        delaycompress
        notifempty
}

/var/log/samba/log.samba {
        weekly
        missingok
        rotate 7
        postrotate
                if [ -d /run/systemd/system ] && command systemctl >/dev/null 2>&1 && systemctl is-active --quiet samba-ad-dc; then
                        systemctl kill --kill-who all --signal=SIGHUP samba-ad-dc
                elif [ -f /var/run/samba/samba.pid ]; then
                        # This only sends to main pid, See #803924
                        kill -HUP `cat /var/run/samba/samba.pid`
                fi
        endscript
        compress
        delaycompress
        notifempty
}

现在根据您的 logrotate 配置，我可以看到这些错误来自哪里。它们来自 smbcontrol 工具，如果找不到 smbd/nbmd PID，它会返回错误代码。

以下是忽略日志轮换脚本中这些错误的简单解决方案：添加行|| true后的/usr/bin/smbcontrol [sn]mbd reload-config内容。即第一部分应如下所示

postrotate [ ! -x /usr/bin/smbcontrol ] || /usr/bin/smbcontrol smbd reload-config || true endscript
