搞定这20个Linux故障,你的运维水平已经超过80%的人

服务器突然连不上、系统起不来、网络时断时续、文件变成只读……搞运维的应该都经历过这种时刻——半夜被报警电话叫醒，一边擦汗一边敲命令，排查半天找不到头绪，越急越乱。

其实Linux的常见故障翻来覆去就那么些，系统启动不了、网络不通、密码忘了、硬盘满了、交换机抽风了。遇得多了你就会发现，大部分问题都是有固定排查套路的。

今天整理了一份Linux运维常见故障排查清单，覆盖了系统故障、网络故障、硬件故障、软件故障四大类，一共20个高频场景。建议直接收藏，下次服务器出问题翻出来对照着查，比临时到处搜答案快得多👇

运维!明明掌握Linux、云、网络多年的功底,却只能困在重复工作中,未免太可惜
