linux服务器报警之利用Java邮件报警

在这里分享下服务器如何利用Java邮件报警

前提：服务器先安装配置好java环境

一、JAVA环境安装

[root@Server2 ~]# tar -zxvf jdk-7u75-linux-x64.gz -C /usr/local
[root@Server2 ~]# vi /etc/profile
export JAVA_HOME=/usr/local/jdk1.7.0_75
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
[root@Server2 ~]# source /etc/profile   快速生效
[root@Server2 ~]# java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

二、脚本配置

上传附件中的脚本目录到/var/scripts后解压

修改tomail.sh

#!/bin/bash

export LANG=en_US.UTF-8


HOST="smtp.163.com"
SENDER="[email protected]"
PASSWORD="xxxxxxxx"


RECEIVER="[email protected]"

#报警内容
        SUBJECT="request timeout,Please check"
        CONTENT="this eamil from monitor server"
		
#发送邮件
       /usr/local/jdk1.7.0_75/bin/java -cp /var/scripts/monitor:/var/scripts/lib/* SendMails $HOST $SENDER $PASSWORD "$SUBJECT" "$CONTENT" $RECEIVER

配置好的后，执行tomail.sh发送邮件就可以了。

如果报以下错误，请配置下hosts

javax.mail.SendFailedException: Sending failed;

  nested exception is:

        class javax.mail.MessagingException: 501 Syntax: HELO hostname

        at javax.mail.Transport.send0(Transport.java:218)

[root@Server2 ~]# vi /etc/hosts
