![Linux 服务器历史记录不一致](https://linux22.com/image/113957/Linux%20%E6%9C%8D%E5%8A%A1%E5%99%A8%E5%8E%86%E5%8F%B2%E8%AE%B0%E5%BD%95%E4%B8%8D%E4%B8%80%E8%87%B4.png)
我们在生产环境中使用 Cent OS 机器,有时 Web 应用程序 [Jboss] 会给出小时后的时间戳而不是当前时间。即使在服务器历史记录中也有不一致的时间戳。任何人都可以帮我解决这个问题。
我们已经验证了系统日期及其正确性,网络服务器日志也写入了系统日期。但只有访问日志写入的时间戳不一致。

答案1
.bash_history 很简单。该文件不会逐行写入。它通常在 shell 关闭/退出时附加。在多用户系统上,这可能会根据多人登录和退出的时间创建显示的条件。例如,假设您于 08:00 通过 ssh 登录。在 08:00 到 08:05 之间运行了一些命令,但没有注销。然后,您在 09:00 打开另一个 ssh 会话并运行一些命令,并在几分钟后注销。稍后您会发现有一个会话打开(您在 08:00 开始的会话)并退出。 .bash_history 文件会将早期会话的历史记录(包含 08:00-08:05 之间的命令)附加到 09:00 打开的会话退出时附加的命令。我一直在具有共享/应用程序帐户的开发环境中的服务器上看到这种情况。
在 JBOSS 日志中,记下日期和时间后面的+0100
和值。+0000
我假设这些是与 UTC 的偏移量。因此,如果您调整偏移量,上面的 JBOSS 日志将显示:
