一、查看内存使用情况在Linux系统中,大部分操作都通过命令行来完成,因为大部分情况下不开启图形界面。在服务器环境,则只能通过shell执行操作。下面介绍查看内存使用情况的相关命令。 包括物理内存(RAM)和交换内存(swap)。我们经常需要检查服务器的内存使用情况,以及每个进程占用的内存,避免发生资源短缺进而影响用户体验。对...
通过上面的简单指标查看,可以推断mysqld进程异常,多个CPU呈现饱和状态,可能存在着类似死循环的操作,不断的创建线程,导致CUP饱和。进而我们可以排查mysqld服务的进程信息show processlist;。后排查发现确实存在。kill掉对应的外挂,mysqld恢复正常,然后排查外挂的问题。
