学员案例1:
看到 数据库安装到/data/mysql 目录 方向旁边有些乱起一个什么mysql5.89乱七八糟文件 ,你觉得没用 直接 rm -rf 删除 , 现在是清爽了,, 一会 发现业务无非登录全部报错500 无法连接数据库 ?为啥呢 你把数据库干了! 数据库被删除 还不知道为啥呢 ?都是基础不行欠的账 ,所以做运维一定基础扎实。
学员案例2:
当初学习Linux的使用,从基础到服务到集群,都是在虚拟机做的,虽然我告诉我们跟真机没有什么差别,可是对真实环境的渴望日渐上升,不过虚拟机的各种快照却让我们养成了各种手贱的习惯,以致于拿到服务器操作权限时候,就迫不及待的想去试试,记得上班第一天,老大把root密码交给我,由于只能使用xshell,我就想使用xshell,于是悄悄登录服务器尝试改为xshell+密钥登录,因为没有测试,也没有留一个ssh连接,所有重启sshd服务器之后,自己就被挡在服务器之外了,幸好当时我备份了sshd_config文件,后来让机房人员cp过去就可以了,幸亏这是一家小公司,不然直接就被干了……庆幸当年运气比较好
