keepalived 日志设置、邮箱设置和通知

独立的日志设置

vim /etc/sysconfig/keepalived 或/usr/local/keepalived/etc/sysconfig/keepalived
	KEEPALIVED_OPTIONS="-D -S 6"
vim /etc/rsyslog.conf
	local6.*    /var/log/keepalived.log

　配置发送邮件的邮箱设置：

配置发送邮件的邮箱设置：   yum install mailx -y
 vim ~/.mailrc 或 /etc/mail.rc
set from=348987564@qq.com
set smtp=smtp.qq.com
set smtp-auth-user=348987564@qq.com 
set smtp-auth-password=univdqnrmunjcafh  #邮箱需要开启POP3/SMTP服务并设置密钥
set smtp-auth=login
set ssl-verify=ignore

测试：echo test mail | mail -s testa 收件人id@qq.com

　邮件通知和脚本的调用方法：keepalived服务器都要设置。

chmod 777   /etc/keepalived/notify.sh

测试
bash /etc/keepalived/notify.sh master 先测试能不能收到邮件
