解决linux下创建用户时出现 Creating mailbox file: 文件已存在

时间:2019-05-01 18:39:28   收藏:0   阅读:1207

原来linux下添加用户后,会在系统里自动加一个邮箱(系统邮箱),路径是:/var/spool/mail/用户名.
      可以直接用命令#rm -rf /var/spool/mail/用户名
      这样就可以再次添加同一名字的用户.

 

解决You have new mail in /var/spool/mail/root提示

终端远程登陆后经常提示You have new mail in /var/spool/mail/root

这个提示是LINUX会定时查看LINUX各种状态做汇总,每经过一段时间会把汇总的信息发送的root的邮箱里,以供有需之时查看。

一般这种情况mail的内容就只是一些正常的系统信息或者是比较重要的错误报告。

如果你安装了mutt的话直接用这个命令就可以查看mail的内容(用root登陆先),没有装的话用cat /var/spool/mail/root查看(用root登陆先)。

查看内容:

也可以设置把这个信息发送到管理员邮箱

日志分析工具 Logwatch能够对Linux 的日志文件进行分析,并自动发送mail给相关处理人员,可定制需求 Logwatch的mail功能是借助宿主系统自带的mail server发邮件的,系统需安装mail server , 如sendmail,postfix,Qmail等,具体配置不叙述
