1.查看是否已安装邮件服务 rpm -qa|grep mail
2. 如果没有mailx，则安装
yum install -y mailx3.配置 cat /etc/mail.rc
set [email protected]
set smtp=smtp.qq.com
set [email protected]
set smtp-auth-password=xxxx
set smtp-auth=login如图：
注：smtp-auth-password 是授权密码，不是邮箱密码。设置如下图，qq邮箱账户设置，生成授权码，然后设置smtp-auth-password
4.发送邮件
mailx -s "centos7测试邮件" [email protected] < ~/test.txtecho 'hello' | mail -s "Linux测试" [email protected]cat ~/test.txt | mail -s "邮件测试" [email protected]
