set smtp-auth-user=2956694705@qq.com
set smtp-auth-password=ikbaocjbnogadfci
set smtp-auth=login
3.配置mail.rc文件
passwd 是授权码
4 .配置qq邮箱
点击设置
开启IMAP/SMTP服务生成授权码
5.编写shell脚本实现网址判断
#!/bin/bash
w=(
www.baidu.com www.youku.com www.bw.com
)
qq="[email protected]"
aa="报警"
bb="网站不存在"
for i in "${w[@]}"
do
ping -c 1 $i &> /dev/null
if [ $? -eq 0 ];then
echo "$i ok"
else
echo "$i 不存在"
mail -s "这是无效域名" 2956694705@qq.com < /root/shell/haha.txt
echo "已经发送报警文件到邮箱,请查询."
fi
done
