Centos 5.3 tar 和 rpm 总是给出分段错误 - 你能从 strace 中看出原因吗？

  • 772

（更新：今天，tar 在没有段错误的情况下工作，系统上没有已知的更改。“rm”命令现在是段错误。啊！也许这是由 ESXi 引起的？或者，也许是硬件。）

我有一个在 VMWare ESXi 上运行的 Centos 5.3 系统。它已经运行了一段时间，没有太大问题。然而，最近，我注意到 tar 命令和 rpm 命令在我运行它们时会出现分段错误。

所以，我尝试使用 strace（发现有人在网上提出了这个建议），下面是我使用 strace 时得到的结果。我想知道如何修复我的系统以及如何防止将来发生这种情况。

提前谢谢大家！

  1. 即使没有太多调查，根据您的描述，一些程序开始出现段错误，然后它们开始正常工作，而其他程序开始出现故障，您的内存模块或预链接损坏。

    首先，停止所有虚拟机，重新启动主机并运行内存测试。您必须从 ESXi 外部执行此操作。如果您发现任何内存缺陷，那就是您的问题。更换硬件。

    如果没有发现内存缺陷，请检查您是否正在为您的架构运行来自 CentOS 的最新可用内核。

    再次启动主机和服务器，服务器处于单用户模式（将“single”传递给 grub 内核参数）并运行：

    prelink -avf

    预链接完成后，您应该重新启动服务器。您也可以telinit u && init 3恢复启动，但最好重新启动以确保所有二进制文件都将使用新的内存映射重新加载。

  2. 这是一个猜测，但是，请尝试关闭 se-linix 并查看它是否有效。

    它不应该是段错误，但是，可能有一个文件由于 se-linux 而无法打开，这是 tar 从未想过会发生的。

    否则，您必须安装 tar 的源 rpm，并通过调试构建它，然后在调试器中运行它以查看原因。

    好吧，没有我想象的那么复杂。服务器遭到入侵，天才黑客搞砸了 root 工具包安装。所以，影响是二进制segfaulting。另一个影响是来自服务器的意外网络流量。感谢所有回复的人！

  4. 好吧，听起来很有趣。

    首先，您是否有两个相同的最新框（其中一个不是段错误的）？

    如果是这样，请检查存在段错误的二进制文件的 md5sum，确保它们相同。

    接下来，在失败的二进制文件上运行 ldd，然后在库上运行 md5sum 以查看它们是否不同。

    现在，假设库是相同的，还有其他问题，可能是机器环境或配置，但让我们看看 strace 是否有任何启发。

    引用您的 strace，接近尾声，您有：

     open("/proc/mounts", O_RDONLY|O_LARGEFILE) = 3
 fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f85000
 read(3, "rootfs / rootfs rw 0 0\n/dev/root"..., 4096) = 587
 read(3, "", 4096)                       = 0
 close(3)                                = 0
 munmap(0xb7f85000, 4096)                = 0

    下一行是段错误消息。

    在我的 CentOS 5.3 机器（rpm 版本 4.4.2.3）上，我的 rpm 立即执行以下操作：

    open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=56458752, ...}) = 0
mmap(NULL, 56458752, PROT_READ, MAP_PRIVATE, 3, 0) = 0x2b36f9d01000
close(3)                                = 0

    因此，我敢说问题是在读取 /proc/mounts 或打开 /usr/lib/locale/locale-archive 后关闭内存。由于 munmap() 返回 0，我会在语言环境树上咆哮。

    顺便说一句，如果您的配置不包括语言环境，我执行的下一个块是：

     open("/usr/lib/rpm/rpmpopt-4.4.2.3", O_RDONLY) = 3
 lseek(3, 0, SEEK_END)                   = 23100
 lseek(3, 0, SEEK_SET)                   = 0
 read(3, "#/*! \\page config_rpmpopt Defaul"..., 23100) = 23100
 close(3)

    祝你好运，让我们知道你发现了什么。
