grep '^[a-Z]' /etc/zabbix/zabbix_server.conf
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000
cd /usr/lib/zabbix/alertscripts
2、sendEmail脚本
vim sendEmail.sh
#!/bin/bash
LOGFILE="/tmp/Email.log"
:>"$LOGFILE"
exec 1>"$LOGFILE"
exec 2>&1
SMTP_server='smtp.test.cn' #SMTP服务器，变量值需要自行修改
username='my@test.com' #用户名，变量值需要自行修改
password='$passwd ' #密码，变量值需要自行修改
from_email_address='my@test.com' #发件人Email地址，变量值需要自行修改
to_email_address="$1" #收件人Email地址，zabbix传入的第一个参数
message_subject_utf8="$2" #邮件标题，zabbix传入的第二个参数
message_body_utf8="$3" #邮件内容，zabbix传入的第三个参数
# 转换邮件标题为GB2312，解决邮件标题含有中文，收到邮件显示乱码的问题。
message_subject_gb2312=`iconv -t GB2312 -f UTF-8 << EOF
$message_subject_utf8
EOF`
[ $? -eq 0 ] && message_subject="$message_subject_gb2312" || message_subject="$message_subject_utf8"
# 转换邮件内容为GB2312，解决收到邮件内容乱码
