配置 and stream code 解決 origin bre afa baseline
原來linux下添加用戶後,會在系統裏自動加一個郵箱(系統郵箱),路徑是:/var/spool/mail/用戶名.
可以直接用命令#rm -rf /var/spool/mail/用戶名
這樣就可以再次添加同一名字的用戶.
解決You have new mail in /var/spool/mail/root提示
終端遠程登陸後經常提示You have new mail in /var/spool/mail/root
這個提示是LINUX會定時查看LINUX各種狀態做匯總，每經過一段時間會把匯總的信息發送的root的郵箱裏，以供有需之時查看。
一般這種情況mail的內容就只是一些正常的系統信息或者是比較重要的錯誤報告。
如果你安裝了mutt的話直接用這個命令就可以查看mail的內容（用root登陸先），沒有裝的話用cat /var/spool/mail/root查看（用root登陸先）。
查看內容：
[[email protected] ~]# cat /var/spool/mail/root From [email protected] Wed May 1 14:59:35 2019 Return-Path: <[email protected]> X-Original-To: root Delivered-To: [email protected] Received: by tan.localdomain (Postfix,from userid 0) id AD13C101A70C; Wed, 1 May 2019 14:59:34 +0800 (CST) To: [email protected] From: [email protected] Auto-Submitted: auto-generated Subject: *** SECURITY information for tan *** Message-Id: <20190501065934[email protected]> Date: Wed, 1 May 2019 14:59:34 +0800 (CST) tan : May1 14:59:34 : tan : user NOT in sudoers ; TTY=pts/1 ; PWD=/home/tan ; USER=root ; COMMAND=/sbin/useradd tan2 From [email protected] Wed May 1 15:04:53 2019 Return-Path: <[email protected]> X-Original-To: root Delivered-To: [email protected] Received: by tan.localdomain (Postfix, from userid 0) id F0D65101A70C; Wed, 1 May 2019 15:04:52 +0800 (CST) To: [email protected] From: [email protected] Auto-Submitted: auto-generated Subject: *** SECURITY information for tan *** Message-Id: <20190501070452[email protected]> Date: Wed, 1 May 2019 15:04:52 +0800 (CST) tan : May 1 15:04:52 : tan : user NOT in sudoers ; TTY=pts/1 ; PWD=/home/tan ; USER=root ; COMMAND=/sbin/useradd tan2 From [email protected] Wed May 1 15:06:08 2019 Return-Path: <[email protected]> X-Original-To: root Delivered-To: [email protected] Received: by tan.localdomain (Postfix, from userid 0) id C3BD8101A70C; Wed, 1 May 2019 15:06:08 +0800 (CST) To: [email protected] From: [email protected] Auto-Submitted: auto-generated Subject: *** SECURITY information for tan *** Message-Id: <20190501070608[email protected]> Date: Wed, 1 May 2019 15:06:08 +0800 (CST) tan : May 1 15:06:08 : tan : user NOT in sudoers ; TTY=pts/1 ; PWD=/home/tan ; USER=root ; COMMAND=/sbin/useradd tan2 From [email protected] Wed May 1 15:18:14 2019 Return-Path: <[email protected]> X-Original-To: root Delivered-To: [email protected] Received: by tan.localdomain (Postfix, from userid 0) id 68249101A71A; Wed, 1 May 2019 15:18:14 +0800 (CST) To: [email protected] From: [email protected] Auto-Submitted: auto-generated Subject: *** SECURITY information for tan *** Message-Id: <20190501071814[email protected]> Date: Wed, 1 May 2019 15:18:14 +0800 (CST) tan : May 1 15:18:14 : tan : user NOT in sudoers ; TTY=pts/1 ; PWD=/etc ; USER=root ; COMMAND=/bin/cat sudoers
也可以設置把這個信息發送到管理員郵箱
日誌分析工具 Logwatch能夠對Linux 的日誌文件進行分析，並自動發送mail給相關處理人員，可定制需求 Logwatch的mail功能是借助宿主系統自帶的mail server發郵件的，系統需安裝mail server , 如sendmail，postfix,Qmail等，具體配置不敘述
