当我尝试访问我的 Plesk 管理页面时，似乎无法访问。经过粗略检查后，我发现服务器没有监听端口 8443 上的传入请求（通过 telnet 远程验证）。
因此我假设该服务没有运行，并在 root 帐户下通过 SSH 发出以下命令：
/etc/init.d/psa start
输出结果如下：
Starting xinetd service... done
Starting named service... done
Starting mysqld service... done
Starting postgresql service... done
Starting psa-spamassassin service... done
Plesk: Starting Mail Server... already started
Starting Plesk... failed
Starting drwebd service... not installed
作为一个可能相关的问题，今天我遇到了服务器中断，原因尚不清楚。作为调查的一部分，我使用 Plesk 重新启动服务器。此操作成功完成，是我在 Plesk 中执行的最后一个操作。自重新启动以来，我可以访问除 Plesk 本身之外的所有服务。
我以前从未遇到过这个问题，而且在管理基于 Linux 的服务器方面也是新手，我不知道下一步该怎么做？是否有日志文件可以检查服务启动错误？解决方案就在眼前吗？或者可能是其他原因。
提前致谢
编辑 其他可能相关也可能不相关的内容：
重启后，在再次尝试访问 Plesk 之前，我使用 yum 安装了 sysstat，以便能够使用 iostat。除此之外，没有对服务器进行任何其他更改。

文件中的最后一项/var/log/sw-cp-server/error_log是
2010-12-10 18:35:34: (log.c.75) server started
2010-12-10 18:35:34: (network.c.336) SSL: error:00000000:lib(0):func(0):reason(0)
如果我尝试使用前面提到的命令启动 Plesk，错误日志中会添加 2 个新条目（与上面的相同）。我找到了一些对此错误日志条目的引用，这些引用与 SSL 中断的 plesk 的更新版本有关，但是据我所知，我还没有更新 SSL（除非 sysstat 的安装在后台执行了此操作？？）
输出df -h为：
Filesystem Size Used Avail Use% Mounted on
/dev/md1 9.2G 5.2G 3.7G 59% /
/dev/md5 9.4G 2.2G 7.2G 23% /usr

我敢打赌 /var 所在的分区已经满了。检查df -h一下是否是这种情况。有一个日志文件（来自记忆，所以如果我稍微错了，请使用 tab 完成）/var/log/sw-cp-server/error_log
