如何查看通过 systemctl 命令启动的服务的日志
发表于|更新于|编程文摘
|浏览量:
systemctl 是 Linux 系统服务管理工具,它可以用来启动、停止、重启、启用或禁用系统服务。当我们启动一个服务时,systemctl 会记录服务的启动日志,我们可以通过查看这些日志来排查服务启动时的问题。
查看 systemctl 服务日志的步骤如下:
找到服务的完整名称。系统服务的名称通常以 .service 结尾,例如 httpd.service、mysql.service 等。
使用
journalctl命令查看服务的日志。命令格式为:
1 | journalctl -u <服务名称> |
将 <服务名称> 替换为服务的完整名称。例如,要查看 httpd 服务的日志,运行:
1 | journalctl -u httpd.service |
journalctl会输出服务的启动日志、运行日志和停止日志。

【Linux常用命令】查看主机名
主机名(英语:hostname),也称计算机名,是指分配给计算机的一串唯一标识码,用于在网络上唯一识别该计算机。通常由字母、数字组成,也可以包含一些特殊字符,如英文连字符(-)、英文句点(.)和下划线(_)。典型的主机名最多包含 253 个字符。 在大多数 Linux 发行版中,主机名通常存储在 /etc/hostname 文件中。默认情况下,通过 ssh 命令在终端成功连接到目标服务器时,也可以看到目标服务器的主机名。如以下命令可以看到目标服务器的主机名为 kafka-eagle。 123456$ ssh hadoop@10.10.18.8Last login: Fri May 13 20:50:56 2022 from 10.10.18.215Welcome to Alibaba Cloud Elastic Compute Service ![hadoop@kafka-eagle ~]$ 介绍完主机名的概念,接下来,我们一起了解在 Linux 操作系统中其他各种查找主机名的命令。 使用 hostname 命令hostname 命令用于显示 Linux 系统的 DNS 名称和主...
