如何在 CentOS 上安装 corosync 包的调试符号？

我遇到了崩溃，corosync我想在 gdb 中查看。但是，目前核心转储仅向我显示这么多信息

我想我需要安装调试信息包，corosync无论是什么libtotem_pg.so.4。这个怎么做？

通常，当您启动时，gdb它会显示一条消息，告诉您如何安装所需的调试符号。

例如：

# gdb /usr/sbin/corosync

Missing separate debuginfos, use: debuginfo-install corosync-2.4.3-2.el7_5.1.x86_64
(gdb)

请参阅提示之前的最后一行：

Missing separate debuginfos, use: debuginfo-install corosync-2.4.3-2.el7_5.1.x86_64

因此，在这种情况下，您可以通过在 shell 中（而不是在 gdb 中）运行以下命令来安装调试符号：

debuginfo-install corosync-2.4.3-2.el7_5.1.x86_64

您没有指定您使用的 CentOS 版本。以上是针对 CentOS 7 的。它在 CentOS 6 上的工作方式相同，但您不能剪切和粘贴该命令，因为库版本不同。
