zabbix实现邮件告警的方法(邮箱告警)

根据网络教程实现。zabbix3.4，使用脚本和sendEmail。

1.下载并解压缩sendEmail到/usr/local/bin下面，修改权限。

下载网址：

SendEmail - Send email with this free command line email client http://caspian.dotconf.net/menu/Software/SendEmail/

修改权限：

chownzabbix:zabbix/usr/local/bin/sendEmail

2.进行发邮件测试。

/usr/local/bin/sendEmail -f xxxx@163.com(发件邮箱) -s smtp.163.com -u "邮件标题" -m "邮件内容" -o message-content-type=html -o message-charset=utf8 -xu xxxx@163.com（发件邮箱账号） -xp “网易邮箱授权码” -t “目标邮箱”

3.发邮件测试通过后，进入/usr/local/zabbix/share/zabbix/alertscripts/目录，并新建mail.sh文件，授予权限；

4.mail.sh内容：

#!/bin/bash
to=$1
subject=$2
body=$3
/usr/local/bin/sendEmail -o tls=auto -f xxxx@163.com -t "$to" -s smtp.163.com -u "$subject" -o message-content-type=html -o message-charset=utf8 -xu xxxx@163.com -xp "邮箱客户端授权码" -m "$body"

5.测试报错

[root@centos7 alertscripts]# ./mail.sh “目标邮箱” test_topic hello_world!

 possibly with SSL_ca_file|SSL_ca_path for verification.
 If you really don't want to verify the certificate and keep the
 connection open to Man-In-The-Middle attacks please set
 SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.

在sendemail中1906行的内容，从

if (! IO::Socket::SSL->start_SSL($SERVER, SSL_version => ‘SSLv3 TLSv1‘)) {

修改为

if (! IO::Socket::SSL->start_SSL($SERVER)) {

再次测试，成功。

[root@centos7 alertscripts]# ./mail.sh “目标邮箱” test_topic hello_world!

6.zabbix-web配置

在zabbix3.4中，有3处需要配置，actions，media type，users。actions负责判断，发送邮件；media type负责选择脚本，传递参数；users负责明确告警信息发送给谁等信息。

按照官网的介绍配置即可，这部分实在懒得写了。唯一需要注意的是，media type需要添加3个参数，分别是{ALERT.SENDTO},{ALERT.SUBJECT},{ALERT.MESAGE}，分别对于mail.sh中的to、subject和body。
