篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了centos8.4中的journalctl使用相关的知识，希望对你有一定的参考价值。

journalctl 用来查询 systemd-journald 服务收集到的日志。systemd-journald 服务是 systemd init 系统提供的收集系统日志的服务。journalctl通常用来查询systemd管理的Unit的日志信息。

[root@ocky-Linux-8-4 ~]# journalctl --help
journalctl [OPTIONS...] [MATCHES...]

Query the journal.

Options:
     --system                Show the system journal

(3).查看系统本次启动的日志

journalctl -b

(4).查看上一次启动的日志（需更改设置）

在该[Journal]部分下，将该Storage=选项设置为 persistent 以启用持久记录：

vim /etc/systemd/journald.conf

centos8.4中的journalctl使用_MySQL

在您的服务器上启用了保存以前的引导时，journalctl提供了一些命令来帮助您将引导作为分割单位来使用。要查看journald知道的引导，请使用以下–list-boots选项journalctl：

[root@ocky-Linux-8-4 ~]# journalctl --list-boots
-1 45bea3c8b1d64502b645856369b015cc Fri 2021-11-19 14:21:35 CST—Fri 2021-11-19 14:25:35 CST
 0 b91e19e4f5554920802c689baa7d6bd8 Fri 2021-11-19 14:25:59 CST—Fri 2021-11-19 14:27:55 CST
[root@ocky-Linux-8-4 ~]#

这将为每次启动显示一行。第一列是启动的偏移量，可用于轻松引用启动journalctl。如果您需要绝对参考，则启动ID位于第二列。您可以通过在结束时列出的两个时间规范来指出引导会话引用的时间。

要显示来自这些引导的信息，您可以使用来自第一列或第二列的信息。

例如，要查看上一次启动的日志，请使用-1带有该-b标志的相对指针：

journalctl -b -1

[root@ocky-Linux-8-4 ~]# journalctl -b -1

(5).查看指定时间的日志

可以使用–since和–until选项过滤任意时间限制，这些限制分别显示给定时间之前或之后的条目。例如："显示2021年11月19号，14点20分30秒到当前时间之间的所有日志信息"

[root@ocky-Linux-8-4 ~]# journalctl --since="2021-11-19 14:20:30"
-- Logs begin at Fri 2021-11-19 14:21:35 CST, end at Fri 2021-11-19 14:27:55 CST. --
Nov 19 14:21:35 localhost.localdomain kernel: Linux version 4.18.0-305.3.1.el8_4.x86_64 (mockbuild@ord1-prod-x86build003.svc.aws.rockylinux.org) (gcc version 8.4.1 20200928 (Red Hat 8.4>
Nov 19 14:21:35 localhost.localdomain kernel: Command line: BOOT_IMAGE=(hd0,msdos2)/vmlinuz-4.18.0-305.3.1.el8_4.x86_64 root=/dev/mapper/rl-root ro crashkernel=auto resume=/dev/mapper/r>
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x001: x87 floating point registers
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x002: SSE registers
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x004: AVX registers
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x008: MPX bounds registers
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x010: MPX CSR
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x020: AVX-512 opmask
Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: Supporting XSAVE feature 0x040: AVX-512 Hi256

Nov 19 14:21:35 localhost.localdomain kernel: x86/fpu: xstate_offset[2]:  576, xstate_sizes[2]:  256

另外，journal还能够理解部分相对值及命名简写。例如，大家可以使用“yesterday”、“today”、“tomorrow”或者“now”等表达。另外，我们也可以使用“-”或者“+”设定相对值，或者使用“ago”之前的表达。

例如获取昨天的日志如下：

journalctl --since="yesterday"

获取某一个时间段到当前时间的前一个小时的日志

journalctl --since 09:00 --until "1 hour ago"

获取当前时间的前20分钟的日志

journalctl --since "20 min ago"

获取某一天到某一个时间段的日志信息

journalctl --since "2021-11-18" --until "2021-11-19 15:00"

2.按消息兴趣过滤

(1).按服务

查看mysqld服务的日志信息

[root@ocky-Linux-8-4 ~]# journalctl -u mysqld.service      
-- Logs begin at Fri 2021-11-19 14:21:35 CST, end at Fri 2021-11-19 16:01:01 CST. --
Nov 19 14:21:39 ocky-Linux-8-4 systemd[1]: Starting LSB: start and stop MySQL...
Nov 19 14:21:42 ocky-Linux-8-4 mysqld[883]: Starting MySQL... SUCCESS!
Nov 19 14:21:42 ocky-Linux-8-4 systemd[1]: Started LSB: start and stop MySQL.

Nov 19 14:25:34 ocky-Linux-8-4 mysqld[2532]: Shutting down MySQL. SUCCESS!
Nov 19 14:25:34 ocky-Linux-8-4 systemd[1]: mysqld.service: Succeeded.
Nov 19 14:25:34 ocky-Linux-8-4 systemd[1]: Stopped LSB: start and stop MySQL.
-- Reboot --
Nov 19 14:26:03 ocky-Linux-8-4 systemd[1]: Starting LSB: start and stop MySQL...
Nov 19 14:26:06 ocky-Linux-8-4 mysqld[879]: Starting MySQL... SUCCESS!
Nov 19 14:26:06 ocky-Linux-8-4 systemd[1]: Started LSB: start and stop MySQL.
[root@ocky-Linux-8-4 ~]#

(2).按进程、用户或者群组ID

由于某些服务当中包含多个子进程，因此如果我们希望通过进程ID实现查询，也可以使用相关过滤机制。

这里需要指定_PID字段。例如，如果PID为8227，则可输入：

journalctl _PID=8227

(3).按优先级

管理员们可能感兴趣的另一种过滤机制为信息优先级。尽管以更为详尽的方式查看日志也很有必要，不过在理解现有信息时，低优先级日志往往会分散我们的注意力并导致理解混乱。

大家可以使用journalctl配合-p选项显示特定优先级的信息，从而过滤掉优先级较低的信息。

例如，只显示错误级别或者更高的日志条目：

journalctl -p err -b

[root@hospital-web1 ~]# journalctl -p err -b
-- Logs begin at Fri 2021-09-17 04:19:02 CST, end at Fri 2021-11-19 16:17:01 CST. --

[root@hospital-web1 ~]#

这将只显示被标记为错误、严重、警告或者紧急级别的信息。Journal的这种实现方式与标准syslog信息在级别上是一致的。大家可以使用优先级名称或者其相关量化值。以下各数字为由最高到最低优先级：

    0: emerg
    1: alert
    2: crit
    3: err
    4: warning
    5: notice
    6: info
    7: debug

例如：

[root@hospital-web1 ~]# journalctl -p 3 -b
