<pstyle="box-sizing:inherit;margin-top:16px;margin-bottom:16px;white-space-collapse:preserve;">使用命令<codestyle="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;padding:0.2em0.4em;margin:0px;white-space-collapse:break-spaces;background-color:var(--color-neutral-muted);border-radius:6px;">dmesg:该命令用于显示内核环缓存的信息,包括进程崩溃信息。通过运行以下命令,您可以查看最近的内核日志信息:

bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">dmesg|grep-i"error"#查找包含关键词"error"的日志信息<pstyle="box-sizing:inherit;margin-top:16px;margin-bottom:16px;white-space-collapse:preserve;">请注意,这只会显示最近的一些崩溃信息。如果您需要更多的详细信息,可以使用以下命令:

bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">dmesg|less#进入分页模式查看完整的内核日志信息<pstyle="box-sizing:inherit;margin-top:16px;margin-bottom:16px;white-space-collapse:preserve;">使用命令<codestyle="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;padding:0.2em0.4em;margin:0px;white-space-collapse:break-spaces;background-color:var(--color-neutral-muted);border-radius:6px;">journalctl:该命令用于查看系统日志信息,可以查看进程崩溃的相关日志。通过以下命令显示与崩溃相关的日志:

bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">journalctl-perr#显示错误级别(Error)的日志信息<pstyle="box-sizing:inherit;margin-top:16px;margin-bottom:16px;white-space-collapse:preserve;">如果要查看特定进程的崩溃信息,您可以指定进程名称或进程ID进行过滤:

bash<preclass="code-block-wrapper"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;margin-top:16px;margin-bottom:16px;overflow-wrap:normal;padding:24px16px16px;overflow:auto;line-height:1.45;background:#e6e7e9;border-radius:6px;transition:background0.1sease-in-out0s;position:relative;width:538.003px;"><codeclass="hljscode-block-bodybash"style="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:16px;color:#383a42;background:transparent;padding:0px;margin:0px;border-radius:6px;word-break:normal;border:0px;display:block;overflow:autovisible;line-height:1.6;overflow-wrap:normal;">journalctl_SYSTEMD_UNIT=<进程名称>.service#以进程名称过滤日志信息journalctl_PID=<进程ID>#以进程ID过滤日志信息<pstyle="box-sizing:inherit;margin-top:16px;margin-bottom:0px;white-space-collapse:preserve;">查看进程的日志文件:进程通常会生成日志文件,记录其运行情况和错误信息。您可以通过查找进程的日志文件来获取崩溃信息。常见的日志文件路径包括<codestyle="box-sizing:inherit;font-family:ui-monospace,SFMono-Regular,'SFMono',Menlo,Consolas,'LiberationMono',monospace;font-size:13.6px;padding:0.2em0.4em;margin:0px;white-space-collapse:break-spaces;background-color:var(--color-neutral-muted);border-radius:6px;">/var/log目录下的各个子目录,以及进程特定的日志文件路径。
